A dead “murder wasp” near Seattle was first discovered in the United States this year | Seattle

Scientists have found a dead giant hornet in the north SeattleThe first so-called murder wasp found in the country this year, a federal and state investigator, said Wednesday.

State and US agricultural entomologists said this was the first confirmed report from Snohomish County in northern Seattle and appears to be unrelated to 2019. 2020 survey results It received widespread attention among the wasps in Canada and Whatcom County along the Canadian border.

The 2 inch long (5 cm long) invading insect first discovered near the US-Canada border in December 2019 is native to Asia. Threaten bees And native wasp seeds. 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 hives, destroy them in just a few hours, and decapitate bees in what scientists call their “slaughter stage.” It is unknown how they came here from Asia.

In a recent sighting, a resident found a dead wasp near the city of Marysville and reported it to the State Department on June 4. An entomologist contacted the person on June 7 and recovered the dead wasp the next day. It turned out to be 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.

State 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.

“This new report continues to emphasize how important public reporting is to all suspicious invasive species, especially the Asian giant hornet,” said the state leading the fight to eradicate wasps. Sven Spichiger, an entomologist at the Department of Agriculture, said.

“We are now trapping the area and encouraging citizen scientists to trap in Snohomish and King counties,” Spichiger said. “This wouldn’t have happened if the alert resident had to take the time to take a picture and submit the report.”

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.

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