The dead “murder hornet” near Seattle was first discovered in the United States in 2021 – NBC Chicago

Scientists have discovered a giant Asian wasp that died north of Seattle. This is the first so-called giant hornet found in the country this year, federal and state investigators said Wednesday.

State and US agricultural insectologists said this was the first confirmed report from Snohomish County in northern Seattle, and Hornet’s 2019 and 2020 surveys were widespread in Whatcom County along the Canada-Canada border. Note that it seems to be irrelevant to the results.

The 2 inch long (5 cm long) invading insect, first discovered near the US-Canada border in December 2019, is native to Asia and threatens honeybees and native wasp species. .. Although not particularly aggressive to humans, their stings are extremely painful and can be killed, although they are rarely repeatedly stung.

The world’s largest wasps are far more threatening to bees that rely on crop pollination. They attack urticaria, destroy urticaria in just a few hours, and decapitate bees in what scientists call the “slaughter stage.” It is unknown how they came here from Asia, but it seems that they are traveling by freighter.

“Hitchhikers are a side effect of all the commerce we do worldwide,” said Sven Spichiger, an entomologist at the State Department of Agriculture, who is leading the fight to eradicate the Hornets.

In recent sightings, residents found dead wasps on the lawn near the city of Marysville and reported them to state officials on June 4. Entomologists recovered it on June 8 and reported that it was a very dry and male wasp.

Entomologists believe that it is a male, an old wasp of the previous season that was previously undiscovered, given the time when the specimens were very dry. New males usually do not appear until at least July.

Officials said there was no clear route for how wasps reached Marysville.

Dr. Osama El Lissie, Deputy Director of the USDA Quarantine Program, said:

El-Lissy said a federal agency would work with state officials to “investigate the area to see if there is a population in Snohomish County.”

The wasp was submitted to the Federal Animal and Plant Health Inspection Service for final verification because it was first discovered in the county and had a different color than previously collected specimens in North America.

On June 11, entomologists confirmed that it was a giant hornet. DNA testing showed that the specimens appeared to be unrelated to the introduction of wasps in Whatcom County or Canada.

According to Spichiger, the newly discovered wasp has no orange band on its abdomen and is most likely from a South Asian country.

“This new report continues to emphasize how important public reporting is to all suspicious invasive species, especially the Asian giant hornet,” he said.

By 2020, half of the giant hornet sightings confirmed in Washington and all of the sightings confirmed in Canada were from the general public, officials said.

“We are now trapping the area and encouraging citizen scientists to trap in Snohomish and King counties,” Spichiger said. “

USDA has added the giant hornet to its list of quarantine pests and offers more tools to help eradicate invasive species in Washington State.
