The eastern yellowjacket is a black and yellow wasp that lives in eastern North America. It builds paper nests, many of them underground, and lives in large family groups called colonies. People often meet it around recreational areas and buildings, and it can give a painful sting if its nest is threatened.1

Anaishi

Eastern North America, extending west as far as the Great Plains1

Amerika Kaskazini

Nyumbani

Most nests are underground and not deep, usually covered by less than 50 mm of soil. Nests are also found in hardwood forests, on creek banks, in urban and suburban areas, and in sheltered places such as tree stumps and attics. Because nests are so often found in recreational and residential areas, it is considered a pest.1

Jinsi ya kumtambua

Black and yellow lines on the head, thorax and abdomen1
Length of about 12.7 to 15.9 mm1
Spots on the head, which give the species its scientific name1
Queens have one flared black line nearest the thorax, followed by thinner black lines, with two black dots between each line1

Mara nyingi huchanganywa na: It can be told apart from other wasp species by its smaller size and its abdominal pattern. Other yellowjacket species are also black and yellow, and in most areas where it lives, this is the most common yellowjacket species.1

Nguvu ya sumu

Kudungwa

Sumu hutoka kupitia mdungo.

Sumu yake hufanya nini?

Its sting is painful. Wasps, bees, ants and sawflies (the order Hymenoptera) are the leading cause of anaphylaxis in humans, a severe allergic reaction. These reactions are usually triggered by proteins in the venom. Peptides called vespulakinins were first found in this species and are insecticidal, meaning they kill insects.1

Ana hatari gani kwa watu?

It is known to inflict painful stings and defends its nest aggressively. Its nests are often treated as a pest because they are found so often in recreational and residential areas.1

Hufanya nini akiogopa?

When threatened, workers release an alarm pheromone that calls others to attack. Wasps near the nest entrance circle in a zigzag pattern and fly straight at the target.1

Akidunga

Kwangua mwiba wa nyuki na upoze mahali hapo.
Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura na umtumie kalamu yake ya adrenalini kama anayo.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

A large nest can have 10,000 to 15,000 cells, and about a third of them are queen cells.1

The nest envelope is made from chewed, decaying wood mixed with saliva, which makes it fragile.1

The species is a host for a social parasite, Vespula squamosa, which can take over its nests.1

Males gather in groups around prominent trees and bushes, where they patrol and wait for queens.1

Queens can mate with several males, and both queens and males can mate more than once.1
