Chestnuts and Chestnuting in Washington DC 100 years ago when there were still a few Chestnuts

Chestnuts and Chestnuting.

The Sunday Evening Star. 27 December 1914. Washington, D.C.[1]

            The Rambler recently wrote of two famous chestnut trees— or the stumps of two famous chestnut trees— in the environs of Washington.  One of these was the chestnut tree in the home grounds of Conway Robinson,[2] called the Vineyard, under which [Senator] Daniel Webster and pious John Agg[3] of Rock Creek Church where want to indulge in toddies, and the other was the chestnut tree on the banks of the Anacostia river, beneath whose spreading branches John Howard Payne[4] and George W. Talbert of Chichester used to drink juleps.  These reflections in chestnut trees bring to Rambler's memory some very pleasant thoughts on the chestnut season now some weeks gone.  It is well understood that the lure of the chestnut is widely felt and has called many persons into the woods.  There is fascination which a large number of men and women cannot resist, or will not resist, not so much in the chestnut as in chestnuting.  They like to scratch among the fallen leaves for the rich, brown, velvet-smooth and fuzzy nuts, or pry them out of their spike-armed and satin-lined chambers, and one chestnut found is to these persons of greater value and sweeter flavor than half a pint bought at the corner stand. 

            On the walk which the great Washington family of wanderlusters made to the summit of Sugarloaf Mountain the Rambler noted an incident which illustrates what has gone before.  It was a long and dusty road from Dickerson {Montgomery County, Maryland] to the base of the mountain, and the "hikers," as they have come generally to be called, were strung out for a mile.  You're the base of the mountain, on its southerly side, is a crossroads with a store and house called Mount Ephraim.  A little beyond that point and off the left of the road, in a copse of chestnut trees, a young girl was hunting, and finding, chestnuts.  She was about 12 or 13 years old.  Her hair, in two bright blonde braids, was hanging down her back.  She carried her big straw hat under one arm and with her free hand rustled among the leaves on the ground.  Her big cat was brimful of chestnuts.

            The Rambler trying to say something about the fun of hunting chestnuts, and the young lady asked him to have some.  An invitation of that kind is not to be resisted and she gave him a handful, and then another, and proceeded to fill one of his coat pockets out of the bounteous store from the old straw hat.
            "What is your name?" The Rambler asked.
            "Oh! it is a hard name and you won't be able to say it," she said in very clear, clean–cut English, but with an accent not of this land.
            "German?" guessed the Rambler.    
            "No," said the little maid, with a trace of indignation in her tone.  "I am Dutch.  I was born in Amsterdam [The Netherlands].  My name is Henrica du Fries."

            That is, the name sounded very much like "Henrica du Fries."  Just then one of the Washington women came along.  She was tired and sunburnt and her tailored skirt with yellow with dust and her shirtwaist, which was so fresh that morning, was no longer fresh.

            "Little girl, may I have some chestnuts?"  she asked, and her tone indicated that she was prepared for a refusal.  But little Henrica came forward with a smile and that big straw hat full of chestnuts and was going to give the strange lady as many chestnuts as she wanted.  Then the strange lady said, in a voice that had grown 20 years younger in a minute:
            "Oh, little girl. I don't want to take your chestnuts, but if you will just let me come in there and help you to find some and find one for myself I will be so glad."

            The child laughed and the woman, laughed, gayly, and climbed through the old fence separating the dusty road from the chestnut trees, and was soon scratching among the leaves and giving out exultant little exclamations when she found the chestnut.

            The Rambler set up on the top rail of the fence, and with satisfaction cracked and choose the chestnuts which he had not found, and in course of half an hour he saw the incident of the woman and the chestnuts repeated, with sundry modifications, half a dozen times.  So he reasoned it out that it was not the chestnuts these men and women wanted, but the fund of finding them, and that they wanted to hunt for them because it brought back were freshened up some pleasant memories of their childhood days.

            A few days later the Rambler was passing over one of the [    ] and sequestered paths of Rock Creek Park, far away from the tracks used by those very ordinary mortals who ride in motor cars.  In the woods a few feet out the past a horse was tethered. He was hitched to a sapling by his bridle rein and the stirrups were thrown across the saddle.  Down among the dry, brown leaves stooped a grave and reverend seignior.  He is a federal judge and everybody who reads this would instantly recognize the name.  He had tied up his horse (which by the way, is a very free and clear footed jumper) and was groping in the leaves for chestnuts, and nibbling the sweetmeat with great satisfaction when he found one.   The Rambler tied up "Nancy" to a tree and fell to chestnuting with the judge. And as they scratched for the nuts the Rambler said:
            "Judge, you know Pat Joyce, the superintendent of this part, would have apoplexy and turn in a right call if he came on us poaching in these woods."[5]
            "Let him have apoplexy, but if you hear him coming we will make our escape," said the judge.  After getting a pocket full of chestnuts the judge and the Rambler moved on through the paths of the woods, and for several miles talked about chestnuts and horses.  Neither Congress nor the administration was mentioned once.

            Not long after this incident the Rambler was passing along that high part of the park on the backbone of land between Rock creek and Broad branch          , up near the jumping field. There are some chinquapin bushes and chestnut trees up there, but, of course, the chinquapins had been stolen several weeks before.  Squatting on the ground was a general in active service, perhaps the best-known general in the city, and who rides one of the best sorrel thoroughbreds that go over the brush hurdles, the bars and that turf–topped stone wall in Rock Creek Park.  His wife was sitting by him. They had a knotted handkerchief full of chestnuts which they had abstracted from this national preserve; and chicken sandwiches.  Their automobile, one of those large,closed-in affairs with a mechanician [sic] and a footman in livery, was standing by the roadside about 200 yards away. 
            "Have some chestnuts?"  Said the general.
            The Rambler told him that he had already stolen so many out of Pat Joyce's woods that he felt a little ashamed of himself, but that he would take a sandwich if there was one left.  And there was.
            "Chestnuting is great fun," said the general with the smiling approval of his wife.  "It's just like being children all over again."

            The blight[6] and the ax have destroyed thousands of chestnut trees throughout the eastern states, but the trees that survive or an extraordinarily large crop last season. It has been a great season for apples and chestnuts.  Europe supplied many tons of chestnuts to the United States each year, but the supply has been visibly diminished by the war and Americans are eating native chestnuts just as sweet but not so large as the European variety. The European chestnuts, Castanea sativa is variously called the "French" chestnut, the "Italian" chestnut and the "Spanish" chestnut.   In England they call it the "sweet chestnuts."   It is native to the mountain forests in the temperate regions of western Asia, Europe and North Africa and has been an important article of food with the people of those regions since recorded history began. With them it is not a tidbit to be merrily munched as with us, but a food of which meals are made. This chestnut is grown to some extent also in the United States. It was introduced into this country  by Irenie du Pont at Wilmington Del., in 1803,[7] and there is a record that the French chestnut was grafted on a native chestnut tree by Thomas Jefferson at Monticello in 1773. The native chestnut is formally known as Castanea Americana [Castanea dentata (Marshall) Borkh.], and in some American chestnut grows it has been improved by grafting from selected forms. There is another chestnut grown in the United States which was introduced from Japan into New York State in 1876.[8]

Riggs Jr. was 29 years old when he bought the farm of a bankrupt family friend,reporter John Agg, who had accumulated nearly $14,000 in debt and in March 1842, he petitioned for protection under a new federal bankruptcy law. Among his assets were a “Farm near Rock Creek Church containing about fifty acres” which had been known as “Wheat Yard Heights” and “Evesham Lodge.” [accessed 27 December 2014 at  William Degges, the man who built “Lincoln’s Cottage” November 2010. http://blog.historian4hire.net/2010/11/12/lincolns-cottage/]

[4]  John Howard Payne was born in East Hampton, Long Island, NY on June 9, 1791. n June of 1813, Payne went to England and was the first American actor to invade the British stage. A contemporary noted of Payne’s appearance: "Nature bestowed upon him a countenance of no common order, and though there was a roundness and fairness which but faintly express strong turbulent emotions or display the furious passions, these defects were supplied by an eye which glowed with animation and intelligence. A more extraordinary mixture of softness and intelligence were never associated in a human countenance, and his face was a true index of his heart."

While living in London and Paris, Payne began writing dramas. He also contributed to several operas, in particular, produced by Sir Henry Bishop entitled Clari, the Maid of Milan. This opera included the Payne’s composition “Home, Sweet Home”, written in 1822 and first sung in Covent Garden, England in 1823. After the popularity of the song spread throughout the world and Bishop claimed that in editing the song for Clari he created new music for Payne’s lyrics. This was recognized both popularly and officially and Payne never did receive royalties for his contribution to the song.

[5]  The park remained under the Board of Control until 1918, when Congress made it and its Piney Branch Parkway adjunct part of the park system of the District of Columbia. On September 16 of that year the park was transferred to the jurisdiction of the Office of Public Buildings and Grounds, which had managed the District park system since 1867. Its officer in charge, Col. Clarence S. Ridley, reported to the Army chief of engineers. [11] Grabill, attached to the office of the District engineer commissioner, was separated from the park, but his staff on the ground stayed. It was headed by Patrick Joyce, who had been appointed foreman in 1910, and then included three skilled laborers, a wagon boss, and nine unskilled hands.

[6]  "Before the turn of the century, the eastern half of the United States was dominated by the American chestnut. Because it could grow rapidly and attain huge sizes, the tree was often the outstanding visual feature in both urban and rural landscapes. The wood was used wherever strength and rot-resistance was needed. In colonial America, chestnut was a preferred species for log cabins, especially the bottom rot-prone foundation logs. Later posts, poles, flooring, and railroad ties were all made from chestnut lumber. The edible nut was also a significant contributor to the rural economy. Hogs and cattle were often fattened for market by allowing them to forage in chestnut-dominated forests. Chestnut ripening coincided with the Thanksgiving-Christmas holiday season, and turn-of-the-century newspaper articles often showed train cars filled to overflowing with chestnuts rolling into major cities to be sold fresh or roasted. The American chestnut was truly a heritage tree.

All of this began to change at or slightly before the turn of the century with the introduction of Cryphonectria parasitica, the causal agent of chestnut blight. This disease reduced the American chestnut from its position as the dominant tree species in the eastern forest to little more than an early-succession-stage shrub." [Background on American chestnut and chestnut blight. accessed at http://www.esf.edu/chestnut/background.htm].

[7]  It would be neither safe nor advisable to attempt to give the exact date at which seedlings or nuts of the European chestnut or Spanish Chestnut as it was popularly called were first planted in American soil. Certain it is however that the introduction took place nearly a century ago and that imported trees have been bearing fruit in this country for over fifty years. It was in the region around Philadelphia Pa Wilmington Del and Trenton NJ that the first general introduction took place and from here has occurred the eventual dissemination of the different varieties to other arts of the country.

The initial introduction of foreign nuts was not as would be expected the work of horticulturists who wished to propagate them for economic purposes but the result of efforts made by wealthy individuals to secure rare and interesting trees adapted fo r planting on their new world estates. To the French "Marrons" is accorded the credit of being among the first to introduce the European chestnut. Irenee Dupont the founder of the now famous powder mills bearing his name was a recipient as early as 1802 of chestnut seed and young trees from France. Most of the seed failed to grow but records show that a few trees became established in his garden and flourished for years no doubt serving as a center of distribution for the surrounding country.

[8] The blight fungus disease was first observed in the U.S. killing American chestnuts (Castanea dentata) in 1904. It has been widely accepted since that humans brought the disease to the US from Asia on imported chestnut trees. The first sighting of the fungus was at the Bronx Zoo, New York City. From there, the disease spread like fire throughout the eastern states, and across the entire natural range of the American chestnut. By the 1920s, the disease had even reached southern Ontario, and by the 1930s, the entire stock of American chestnuts was infected, with most of them dying. By 1940, over three and a half billion American chestnuts had been lost to the fungus. In less than four decades, a dominant American tree species had been converted to a threatened species.  [accessed from Chestnut Blight Fungus (Cryphonectria parasitica) http://www.columbia.edu/itc/cerc/danoff-burg/invasion_bio/inv_spp_summ/Cryphonectria_parasitica.htm].

Beefsteak plant, (Perilla frutescens), a Growing Control Problem


Beefsteak plant flower
http://www.biosurvey.ou.edu/okwild/beefsteak.html
               Natural areas, parks and woods of the Lower Chesapeake Bay have yet another early detection of a non indigenous, alien species.  Perilla frutescens (L.) Britton 1894, [synonyms: Ocimum frutescens L.; Perilla ocymoides L.] beefsteak plant, has been found to be spreading beyond Maryland's cultivated, managed gardens and landscapes. Escaped from gardens in New York as early as 1898, it was reported as a weed of wastelands.[1]  Bernard McMahon, the great American horticulturalist, was selling Perilla seed as early as 1804.[2] Marc Imlay, the great weed warrior, has been weeding Perilla from parks in Maryland since 1998.[3]

               Beefsteak plant also known as Chinese basil; purple or perilla mint, is described on the Missori Botanical Garden website as

"an upright, bushy annual that is native from the Himalayas to Southeast Asia. It is related to coleus and basil. It has become a very popular foliage annual and salad herb plant. It grows to 1-3’ (less frequently to 4’) tall. Wrinkled, serrate, broad ovate, medium green leaves (to 4” long) are sometimes tinged with purple. Leaves are aromatic. Two-lipped nettle-like white flowers in spike-like inflorescences (to 4”) bloom at the stem tips in late summer and fall (August – October). Flowers are not particularly showy. This plant has escaped gardens and naturalized throughout many areas of the eastern and central U. S., including central and southern Missouri. Fresh leaves are used in Oriental cooking, salads, soups and as garnishes. Deep red leaves of some perilla varieties purportedly resemble the color of uncooked beef, hence the common name."

USDA Plants - spread of Purilla frutescens
http://plants.usda.gov/core/profile?symbol=pefr4
               Perilla frutescens is reported as invasive in DC, IL, MD, MO, PA, TN, VA,
and WV and occurring in all states east of Colorado, parts of Canada, as well as the State of Washington on the west coast (excluding, for now, the Dakotas). The Forest Service (USDA) is aware that beefsteak plant is often planted as showy ornamentals,  that

"may readily escape cultivation, spreading to disturbed areas where they disrupt native ecosystems. The species has toxic characteristics and very few predators. It is ordinarily avoided by cattle and has been implicated in cattle poisoning. Plants are most toxic if cut and dried for hay late in the summer, during seed production. One reason for beefsteak plants’ survival in pastures is that cattle avoid it. Sold as a salad plant for its dark purple foliage, this member of the mint family is extremely invasive by wind-borne seeds."[4]

Chinese basil or perilla mint - Perilla frutescens
http://cal.vet.upenn.edu/projects/poison/plants/ppperil.htm
               Purdue Extension Service website control recommendations include "...pulling or digging it up, mowing it, or using herbicides. 2,4-D, Milestone®, Forefront®, Weedmaster®, and glyphosate."  Dr. Imlay, however, notes an ominous sign that control of Perilla frutescens, as well as control of Japanese stiltgrass, Microsteigum virineum Camus 1921[1922], is becoming much more difficult. Imlay told me that he and his volunteers removed 100% of the beefsteak plants by hand pulling until 2010 when many newly emergent patches in open space and lightly shaded areas emerged. He also noted that  existing patches of Perilla frutescens  no longer declined by ~80 % each year in 'weeded'  sections of the park as they had in previous years. 

               "In 2010," Imlay said, " I switched to herbicide treatment and sprayed 20 gallons. A great reduction occurred in 2011 and I only had to spray 2.2 gallons along with modest hand pulling. However, in 2012 many new patches appeared, all of which were treated or hand pulled. But this year many, many new and expanded patches have appeared increasing the coverage of beefsteak plant from about 1/10 th acre to about 1/2 acre.  As of September 6 we have already sprayed 60 gallons and only sprayed about half of the beefsteak plant."

         While preventing and introduction is the first line of defense, even the best prevention efforts will not stop all harmful invasive species. In the case of beefsteak plant, however, preventing its introduction has been off the table for over 200 years. However using the tools of IPM (Integrated Pest Management), such as early detection and rapid response (EDRR), at a local level can greatly support effective management and even in some cases elimination. EDRR efforts increase the likelihood that invasions that can lead to establishment and spread of harmful species will be halted and eradicated. Once a species becomes widely established in an ecosystem, the only action possible is the partial mitigation of negative impacts. Based on the work of the ISAC/NISC EDRR Subcommittee, NISC has approved Guidelines for Early Detection and Rapid Response.

More invasive species detected at US ports in the Mid Atlantic


               Insect as well as plant and animal species from around the world can hitch a ride in a manner of speaking, on cargo shipments, moving from their native lands to exotic foreign destinations, and sometimes stay and establish a new home. Ports of entry like Baltimore and Norfolk are doorways to establishment of species that may impact livelihoods by altering the characteristic services of ecological systems.

               The front-line of defense is the U. S. CBP,
"one of the Department of Homeland Security’s largest and most complex components, with a priority mission of keeping terrorists and their weapons out of the U.S. It also has a responsibility for securing the border and facilitating lawful international trade and travel while enforcing hundreds of U.S. laws and regulations, including immigration and drug laws. Amopng other tasks," CBP performs two crucial roles in facilitating trade to and from the U.S. and around the globe: securing it from acts of terrorism and assuring that goods arriving in the U.S. are legitimate and that appropriate duties and fees are paid."[1]

Working with USDA ARS Systematic Entomology Laboratory and USDA APHIS Plant Inspection Stations, and APHIS Plant Protection and Quarantine (PPQ). the organizations work to protect American jobs, businesses and the ecosystems that support them. Recent interceptions of non-native and potentially harmful insect species provide  highlights of the impossible nature of their underfunded mission. USDA APHIS PPQ reported at the Maryland Invasive Species Council's May 2013 meeting the following interceptions.

Macroglossum stellatarum

               At the port in Norfolk, Virginia CBP intercepted for the first time, Macroglossum stellatarum  Linnaeus (1758), the hummingbird hawk-moth. The moth is found though out most of Europe, Asia and Northern Africa. While the species is unable to survive cold winters, the adults are strong enough fliers that they seasonally migrate from the Mediterranean region North to Sweden & Iceland. The Encyclopedia of Life notes that
"The hummingbird hawk-moth is named for its long proboscis (straw like mouth) and its hovering behavior, which, accompanied by an audible humming noise, give it remarkable resemblance to a hummingbird as it visits flowers to feed on nectar."[2]
Humans see various shades of dull brown or grey in the forewings of the moth. On the other hand, they reveal characteristic fluorescent yellow, violet, purple and green patterns under ultraviolet light . Thus to birds and other insects the moth is most likely brightly patterned.[3]

Coreus marginatus

               The Port of Norfolk also saw for the first time the arrival and discovery of Coreus marginatus Linnaeus (1758). The uninvited accidental visitor was found in a shipment of tile from Italy. This species if found throughout most of Europe where it feeds on plants in the genus Rumex. In addition inspectors also discovered at the Norfolk facility an adult moth hiding out amongst military cargo. The moth was identified as Autophila ligaminosa Eversmann (1851). This is the first time this species found in the sub-alpine region from the Balkans west to Afghanistan has been identified entering the US.

               In the historic rivalry between Virginia and Maryland, the Port of Baltimore was not without its own early detection of non native visitors taking advantage of the enormous flow of global trade. And to make matters even worse one of the interception was yet another stink bug. Baltimore CBP found a moderate sized stinkbug in a shipment of tile that was later identified to be Sciocoris sideritidis Wollaston (1858). This is the first time this species has been identified entering the US. Just wait until an undetected mating pair of this new species to the shores of the United States sets up shop and works with the two existing invasive stink bugs already sucking their way through vegetables, fruits, and soya beans. Reducing USDA funding through political mismanagement and grand standing in Congress is a sure way to encourage this opportunity.

             And last but not least, remembering that airports are ports too, a baggage interception in Baltimore was confirmed to be Tetraleurodes andropogoni Dozier (1934), a type of white fly. This is the first time this species have been intercepted entering the US.  According to CPB "the insects were discovered on fresh leaves being carried by a passenger originating from Nigeria and arriving from the United Kingdom."[4]

Updating the Bamboo Wars in Connecticut - Question on the Table

Seems that the Connecticut General Assembly has decided for the moment to side step running bamboo legislation by using the time-honored motion of setting the bill on the table, more commonly referred to as tabled, at least for today; and with the end of the session coming up quickly - maybe gone for good.  

According to a recent posting on the Facebook site, Institute of Invasive Bamboo Research


"Old Burying Ground - Byram Shore, Greenwich, Conn. under invasion by Yellow Groove bamboo. * S.B.1016 REGULATE RUNNING BAMBOO has been tabled - Needs to be Voted on now. The Constituents of Connecticut will not let this bill die."  

The accompanying photograph of a bamboo species taking over a cemetery is a nice touch.

Here is the most current legislative analysis curtesy of the CGA website:

OLR Bill Analysis
sSB 1016
AN ACT REGULATING THE PLANTING AND SALE OF RUNNING BAMBOO.
SUMMARY:
This bill makes people liable for failing to contain “running bamboo” (ie, bamboo in the genus Phyllostachys, including yellow-groove bamboo) on their property beginning October 1, 2013It requires a 100-foot setback from abutting property and a public right of way for running bamboo planted after that date, unless it is properly containedIt also requires people who sell or install running bamboo to educate customers on the plant's growing habits, the bill's provisions, and recommended containment methods.
The bill subjects violators of its setback or containment provisions to a 100 fineIt also subjects violators of its education requirements to a 100 fine, for each plantFines may be mailed to the Central Infractions Bureau without a court appearance.
Lastly, the bill (1) authorizes the Department of Energy and Environmental Protection, in conjunction with the Department of Consumer Protection, and (2) requires environmental conservation officers, to enforce the setback, containment, and education requirements.
EFFECTIVE DATEUpon passage, except the environmental conservation officers' enforcement powers are effective October 1, 2013.
LIABILITY FOR DAMAGE TO NEIGHBORING PROPERTY
Beginning October 1, 2013, the bill makes people who plant running bamboo, or allow it to be planted, on their property liable for any damage the bamboo causes to neighboring properties, including the cost of removing any bamboo that spread to neighboring propertyIt prohibits people from allowing running bamboo to grow beyond their property boundaries.
SETBACK OR CONTAINMENT REQUIRED
The bill requires anyone planting or allowing running bamboo to be planted on his or her property after October 1, 2013 to plant it at least 100 feet from an abutting property or public right-of-wayBut it allows a person to plant within 100 feet if the running bamboo is properly containedThe containment system must be (1) a properly constructed and maintained barrier system or (2) an above ground container that does not allow the bamboo to come in contact with the ground's soil.
Violators are subject to a 100 fine, and each day of a continuing violation is a separate offense.
EDUCATING PURCHASERS
The bill requires retail sellers and installers of running bamboo to provide purchasers of the plant with a statement that includes:
1a disclosure that running bamboo is a fast growing plant that may spread if not properly contained;
2a plain language summary of the billand
3recommendations on how to properly contain the bamboo, based on the best available information.
Violators are subject to a 100 fine for each plant sold without the required statement.

Invasive species 'boxbug' tries to sneak past APHIS

Gonocerus acuteangulatus (Goeze 1778)

               Invasive species are all around us. The eat our lunch, they make us sick, and they change our landscapes. Invasive species cost us money...lots of money...some say over 130 billion dollars a year in the United States alone. Most of only get excited about invasive species when they directly and immediately injure us personally.  We remain landscape illiterate convinces that food comes from stores, and clean water from pipes.

               The United States Department of Agriculture's Animal and Plant Health Inspection Service (USDA APHIS) works to stave off the introduction and establishment of harmful invasive species.[1] APHIS and its ever-smaller budgets is faced with more "stuff' coming in to US ports each year. And who is APHIS' stakeholder that should be clamoring for increases to protect our pockets, food, and health? Why we the very people who have no clue. Somehow we have the idea that the infrastructure started by Lincoln and enhanced by Presidents through the 1960s now needs no support at all. Our arrogance is only unsurpassed by our inability to see tomorrow.

               If you live in the Mid-Atlantic you already know about the stink bug because it decided to not only cost the fruit industry millions but more importantly for you, because it moved in by the thousands to your personal space and caused you discomfort. So you call on APHIS and demand to know why and then fail to give it the money to prevent the next critter from moving in.

               With little support from the calmly disinterested public (those without stink bugs, pythons, flying fish and rock snot in their lives so far), the dedicated employees of APHIS and its sister organizations ARS and the Forest Service) work to keep the next invader out of your personal space. They work tirelessly to safeguard the United States much like the heroic 'Little Dutch boy' who stuck his finger in a hole in the dike to save his world from certain doom.

              And what has APHIS done lately for you - especially those of you who garden or make your living selling plants? In December, the keen eyes of USDA APHIS port inspectors in Baltimore, Maryland spotted for the first time a Coreid, Gonocerus acuteangulatus (Goeze 1778). G. acuteangulatus, commonly called known as a boxbug in the United Kingdom, id a "relatively large reddish-brown squashbug, distinguished from the commoner Coreus marginatus by the narrower abdomen and more pointed lateral extremities of the pronotum. Nymphs have a green abdomen." The website, British Bugs, goes on to describe this new invader to the US as historically very rare in the British Isles and known only from Box Hill in Surrey, where it feeds on box trees (boxwoods). British Buigs continues its report noting that the "bug is expanding its range and now occurs widely in the south-east of England and beyond. It is exploiting different foodplants, and has been found on hawthorn, buckthorn, yew and plum trees." Reports from England report that it seems prefers berry bearing species such as hollies and ivies.[2]  The boxbug is also reported as a major problem for hazelnut production in Italy.[3]

               APHIS also reports that the recently intercepted boxbug, G. acuteangulatust is a primary pest of boxwood, but is also recorded feeding on important landscape and garden plants such as hawthorn, buckthorn, yew and plum trees. According to a report in the Washington Times, the boxbug, referred to as a squashbug in the article, was "destined for Eldersburg, Md.  CBP (U.S. Customs and Border Protection) issued an Emergency Action Notification to the importer requiring the shipment to be re-exported or destroyed."[4]

               The possible introduction of this invasive pest would add to the litany of invasive species problems facing farmers and gardeners in the United States. We, all of us, should be actively supporting enhanced funding for USDA APHIS. It is worth noting that APHIS also quietly protects natural areas from invasive species that creep through our trade routes into our ports and out into our fields and woods.
 



[1] The Animal and Plant Health Inspection Service is a multi-faceted Agency with a broad mission area that includes protecting and promoting U.S. agricultural health, regulating genetically engineered organisms, administering the Animal Welfare Act and carrying out wildlife damage management activities.  These efforts support the overall mission of USDA, which is to protect and promote food, agriculture, natural resources and related issues.

To protect agricultural health, APHIS is on the job 24 hours a day, 7 days a week working to defend America’s animal and plant resources from agricultural pests and diseases.  For example, if the Mediterranean fruit fly and Asian longhorned beetle, two major agricultural pests, were left unchecked, they would result in several billions of dollars in production and marketing losses annually.  Similarly, if foot-and-mouth disease or highly pathogenic avian influenza were to become established in the United States, foreign trading partners could invoke trade restrictions and producers would suffer devastating losses.    http://www.aphis.usda.gov/about_aphis/

"The importer plans to fumigate.
Upon Friday’s discovery of the bug, CBP forwarded the specimen to a USDA Animal and Plant Health Inspection Service Plant Protection and Quarantine entomologist for identification. CBP agriculture specialists work closely with USDA to protect the nation’s agriculture resources against the introduction of foreign plant pests and animal diseases.
CBP agriculture specialists have extensive training and experience in the biological sciences and agricultural inspection. On a typical day, they inspect tens of thousands of international air passengers, and air and sea cargoes nationally being imported to the United States and seize 4,291 prohibited meat, plant materials or animal products, including 470 insect pests."
