54-482: The brown marmorated stink bug ( Halyomorpha halys ) is an insect in the family Pentatomidae , native to China, Japan, Korea, and other Asian regions. In September 1998, it was collected in Allentown, Pennsylvania , where it is believed to have been accidentally introduced. The nymphs and adults of the brown marmorated stink bug feed on over 100 species of plants, including many agricultural crops, and by 2010–11 had become

Vibrational signals of this species are noted for their low frequency , and one male signal type is much longer than any other previously described signals in stink bugs, although the significance of this is not yet clear. The brown marmorated stink bug
162-605: A few live specimens were found in agricultural equipment being imported from Italy. However the Portuguese National Authority for Animal Health regards this as a transitory interception. In 2019, there may have been another sighting somewhere in Portugal. In 2018 arrived to the Basque Country , where the population grew rapidly by October 2023. Only in 2020 was H. halys confirmed to be reproducing and overwintering in
216-518: A field of crops is infected because stink bugs are known for the "edge effect", in which they tend to infest crops 30–40 ft from the edge of the field. Control of stink bugs is a priority of the United States Department of Agriculture , which has developed an artificial pheromone which can be used to bait traps. Because the bugs insert their probosces below the surface of fruit and then feed, some insecticides are ineffective; in addition,
270-535: A laboratory strain being studied in quarantine. Since then, several agricultural authorities have begun programs to augment wild populations with releases of laboratory reared wasps. An adventive European population was discovered during similar surveys in Switzerland in 2017. Several parasitoids and predators indigenous to North America and Europe have been reported to attack stink bug eggs, nymphs and adults. Researchers have also experimented with other predators like

The body shape of adult pentatomids is generally " shieldlike ," when viewed from above, but this varies between species, and is not true for the immature nymphal stages. The forewings of stink bugs are called hemelytra , with the basal half thickened while the apex is membranous. At rest, the wings are laid across the back of the insect, with

Bush green beans are usually cultivars of the common bean ( Phaseolus vulgaris ). Pole beans have a climbing habit and produce a twisting vine, which must be supported by "poles," trellises , or other means. Pole beans may be common beans ( Phaseolus vulgaris ), runner beans ( Phaseolus coccineus ) or yardlong beans ( Vigna unguiculata subsp. sesquipedalis ). Half-runner beans have both bush and pole characteristics, and are sometimes classified separately from bush and pole varieties. Their runners can be about 3–10 feet long. Over 130 varieties (cultivars) of edible pod beans are known. Varieties specialized for use as green beans, selected for
432-421: A resistance to pyrethroid insecticides, a common chemical used to combat infestations. Other insecticides currently in field trials that are showing promising results are oxamyl (96% mortality rate) and moribund (67% mortality rate). Many other commonly used insecticides are merely used to keep the insects out of fields, rather than actually killing them. The most successful method of protecting apples found thus far
486-556: A ride as a stowaway in packing crates or on various types of machinery. The first documented specimen was collected in Allentown, Pennsylvania , in September 1998. Several Muhlenberg College students were reported to have seen these bugs as early as August of that same year. Between 2001 and 2010, 54 sightings were reported of these bugs at shipping ports in the United States. However, stink bugs are not listed as reportable and no action
540-759: A season-long pest in orchards in the Eastern United States. In 2010, in the Mid-Atlantic United States, $ 37 million in apple crops were lost, and some stone fruit growers lost more than 90% of their crops. Since the 2010s, the bug has spread to countries such as Georgia and Turkey and caused extensive damage to hazelnut production . It is now established in many parts of North America, and has recently become established in Europe and South America. Adult brown marmorated stink bugs are approximately 1.7 cm (0.67 in) long and about as wide, forming

However, simply handling the bug, injuring it, or attempting to move it can trigger it to release the odor. Reports on human cases are rare, but the stink bug's body fluids are toxic and irritating to the human skin and eyes. One case of keratitis has been reported in Taiwan . During courtship, the male emits pheromones and vibrational signals to communicate with
702-407: Is a natural predator of the stink bug. Pill bugs eat stink bug eggs. Arilus cristatus , however, was the most voracious predator and attacked the eggs and adults more consistently. The brown marmorated stink bug is more likely to invade homes in the fall than others in the family. The bug survives the winter as an adult by entering houses and structures when autumn evenings become colder, often in
756-422: Is a pest to soybean and fruit crops. In the U.S., the brown marmorated stink bug feeds, beginning in late May or early June, on a wide range of fruits, vegetables, and other host plants including peaches , apples , green beans , soybeans , cherries , raspberries , and pears . The brown marmorated stink bug was accidentally introduced into the United States from China or Japan. It is believed to have hitched
810-421: Is a serious agricultural pest that has been readily causing damage to crops across the Eastern United States. They feed on a wide array of plants including apples, apricots, Asian pears, cherries, corn, grapes, lima beans, peaches, peppers, tomatoes, and soybeans. This makes them extremely versatile, as they do not require a specific plant on which to feed. To obtain their food, stink bugs use their stylets to pierce
864-410: Is a sucking insect (like all Hemiptera or "true bugs") that uses its proboscis to pierce the host plant to feed. This feeding results, in part, in the formation of dimpled or necrotic areas on the outer surface of fruits, leaf stippling, seed loss, and possible transmission of plant pathogens . It is an agricultural pest that can cause widespread damage to fruit and vegetable crops. In Japan, it
918-747: Is evidence that it has been cultivated in Mexico and Peru for thousands of years. The first "stringless" bean was bred in 1894 by Calvin Keeney, called the "father of the stringless bean," while working in Le Roy, New York . Most modern green bean varieties do not have strings. Green beans are classified by growth habit into two major groups, "bush" (or "dwarf") beans and "pole" (or "climbing") beans. Bush beans are short plants, growing to not more than 2 feet (61 cm) in height, often without requiring supports. They generally reach maturity and produce all of their fruit in
972-705: Is required to remove the insect. This allowed the insect to enter the United States relatively easily, as they are able to survive long periods of time in hot or cold conditions. Other reports have the brown marmorated stink bug documented as early as 2000 in New Jersey from a blacklight trap run by the Rutgers Cooperative Extension Vegetable Integrated Pest Management program in Milford, New Jersey . In 2002, in New Jersey, it
1026-411: Is the use of kaolin clay . As of 2012, native predators such as wasps and birds were showing increased signs of feeding on the bugs as they adapt to the new food source. Managing this pest species is challenging, because few effective pesticides are labeled for use against them. Another recently introduced species from Asia, the large but non-threatening spider; Trichonephila clavata , also known as
1080-529: The Ondokuz Mayıs University has stated that the bug has already caused a 20% drop in Artvin's hazelnut yield and is expected to cause a 50% drop in hazelnut production and quality in the future. According to Tuncer, these drops would lead to US$ 1 billion in damages to hazelnut producers. In China, Trissolcus japonicus , a parasitoid wasp species in the family Scelionidae , is a primary predator. In

They are generally a dark brown when viewed from above, with a creamy white-brown underside. Individual coloration may vary, with some bugs being various shades of red, grey, light brown, copper, or black. The term "marmorated" means variegated or veined, like marble , which refers to the markings of this species, including alternating light-colored bands on

Other research investigated different spider species, as well as the wheel bug Arilus cristatus . Several spider species attacked both the eggs and adult stink bugs. The Joro spider , another invasive Asian species, was identified in Georgia in 2015, and
1296-566: The Aphylinae is often given family status, but is here retained as a subfamily, following Grazia et al. (2008). The subfamilies include: European species within this family include: Green bean Green beans are young, unripe fruits of various cultivars of the common bean ( Phaseolus vulgaris ), although immature or young pods of the runner bean ( Phaseolus coccineus ), yardlong bean ( Vigna unguiculata subsp. sesquipedalis ), and hyacinth bean ( Lablab purpureus ) are used in
1350-609: The Joro spider is a known predator of the stink bug while not posing a threat to native species. There is hope that it may be capable of reducing or controlling stink bug populations in North America as it continues to spread. Easily confused with Brochymena and Euschistus , the best identification for adults is the white band on the antennae. It is similar in appearance to other native species of shield bug , including Acrosternum , Euschistus , and Podisus , except that several of
1404-560: The United States, Europe, and New Zealand, Trissolcus japonicus is a focus of biological control programs against the brown marmorated stink bug. This wasp was under study in the United States since 2007 for biosafety of possible introduction. However, in 2014, two adventive populations were found in the United States during surveys to identify which North American parasitoids might be attacking brown marmorated stink bug. Subsequent genetic testing showed these wild populations were self-introduced: they were not related to each other, or to
1458-885: The United States, no matter the climate. In warmer climates, multiple generations can occur annually, which can range from two generations in states such as Virginia to six generations in California, Arizona, Florida, Louisiana, Georgia, and Texas. The addition of two more generations allowed the population to explode, leading to the establishment of several other populations in neighboring states. Currently, no environmental limiting factors are apparently slowing their distribution across North America. They also are extremely mobile insects, capable of moving from host to host without causing disruption in their reproductive processes. Currently, populations are estimated to continue to grow and spread to other states and provinces, especially during unusual periods of warm weather. The brown marmorated stink bug
1512-416: The abdominal segments protrude from beneath the wings and are alternatively banded with black and white (visible along the edge of the bug even when wings are folded) and a white stripe or band on the next to last (fourth) antennal segment. The adult rice stink bug ( Oebalus pugnax ) is distinguishable from the brown marmorated stink bug by noting the straw color, the smaller size, and the elongated shape of

1728-495: The bugs are mobile, and a new population may fly in after the resident population has been killed, making permanent removal nearly impossible. In the case of soybean infestations, spraying only the perimeter of a field may be the most effective method of preventing stinkbugs from damaging the crops. However, even this method is limited, as new populations move back into the area, or the existing population simply moves to unaffected areas. Evidence also shows that stink bugs are developing

The stink bug was traced to have been introduced to the Greater Caucasus area during the construction works of the 2014 Winter Olympics in Sochi , Russia , where it was most likely imported with decorative building elements brought from Italy. The stink bug has since spread to Georgia , where it continues to cause major damage to
1836-459: The eastern half of the United States were reported as having more than normal numbers of stink bugs. Stink bug populations rise because the climate in the United States is ideal for their reproduction. In optimal conditions, an adult stink bug can develop within 35 to 45 days after hatching. Female stink bugs are capable of laying 400 eggs in their lifetimes. The bug is also capable of producing at least one successful generation per year in all areas of
1890-555: The family Acanthosomatidae. The term shield bug refers to the generalized body shape of adult bugs in these families which resembles a heraldic shield when viewed from above. The American name "stink bug" is specific to the Pentatomidae, and refers to their ability to release a pungent defensive spray when threatened, disturbed, or crushed. The composition of this spray may vary between species, and even by sex or age, but generally includes aldehydes and alkanes . Descriptions of

Since its recent arrival in the U.S., the brown marmorated stink bug population has grown significantly. As of October 2014, brown marmorated stink bugs can be found in 41 out of 50 states within the U.S. In 2016 New Zealand's MPI put out an alert to prevent this invasive species from entering via imported cargo. There are several subfamilies, of which
2646-692: The subfamily Asopinae , are predatory and may be considered beneficial. The name "Pentatomidae" is from the Greek pente meaning "five" and tomos meaning "section", and refers to the five segments of their antennae. Pentatomids are generally called "shield bugs" in British English , or "stink bugs" in American English . However, the term shield bugs are also applied broadly to include several related families (e.g. Acanthosomatidae , Scutelleridae , and Cydnidae ), or specifically only to refer to species in

They enter under siding, into soffits , around window and door frames , chimneys, or any space which has openings big enough to fit through. Once inside the house, they go into a state of hibernation. They wait for winter to pass, but often the warmth inside the house causes them to become active, and they may fly clumsily around light fixtures. Two important vectors of this pest are
