GIANT Asian hornets that have begun to invade the coronavirus-stricken U.S. may cost the economy millions of dollars a year.
The insects, which can kill with a single sting, may have a devastating impact on the already dwindling honeybee population in the U.S.
Experts estimate the pests may cause America a staggering $29.3 million as they invade.
The invasion is projected as a coronavirus-stricken U.S. is already facing economic setbacks.
Millions are out of work – with nearly 17 million applying for unemployment in the last three weeks alone – as more than 432,000 cases of the virus have been confirmed in the U.S. alone.
Many experts have warned of a looming recession, as businesses have been forced to shutter their doors due to stay-at-home orders.
Asian hornets are similar to European hornets that live in the U.S., but they are not native to America.
They are large insects measuring almost 2in long, originally from Southeast Asia, that prey on small creatures - especially bees.
Just one sting is enough to kill someone allergic to their venom.
The yellow legged critters were accidentally introduced to France from China in 2004 and they have been spreading rapidly throughout Europe and other parts of the world ever since.
Experts estimate the Asian hornet colonised most of France at a rate of roughly 37 to 50 miles per year.
And the species has swiftly been invading other countries including Spain in 2010, Portugal and Belgium in 2011, Italy in 2012 and Germany in 2014.
The invasive hornets made it to the UK in 2016 – and in December 2019, were first spotted in the U.S. in Washington.
Experts are now warning that the species will begin to swarm in spring, as the hornet's life cycle begins in April.
In a new study – published first in the journal NeoBiota – French scientists evaluated the estimated cost of this non-native hornet invasion to the U.S. and Europe.
They did so by analysing the negative impact Asian hornets have on ecosystems and the global decline in pollination and honey production.
The invasion is mainly controlled by destroying hornet nests and bait trapping.
But the authors say these methods are not enough to completely eradicate the species.
The team divided costs into three main categories - prevention of the invasion, fighting the invasion, and damage caused by the invasion.
The cost of fighting the invasion was the price of nest destruction - calculated by studying the companies that provide the service.
Research leader Professor Franck Courchamp said just two years after the hornet was first spotted in France, estimates show it cost roughly $446,000 to destroy nests.
"Since then, the estimated yearly costs have been increasing by about 450,000 euros each year (roughly $492,000), as the hornet keeps spreading and invades new departments.
Courchamp said over a ten-year period – from 2006 to 2015, the nest destruction cost more than $25 million, according to estimates.
The hornets may cause more than $29 million in damage to the U.S.
So far, nest destruction is the most effective way to fight the invasion but experts say it is not enough to kill off the species.
Only 30 to 40 per cent of the detected nests are destroyed each year in France.
And those that are destroyed are the ones that have been deemed particularly harmful to human or beekeeping activities.
The scientists are calling for more active measures and research into the invasion of Asian hornets.
Professor Courchamp said: "The current study presents only the first estimates of the economic costs resulting from the Asian hornet, but definitely more actions need to be taken in order to handle harmful invasive species - one of the greatest threats to biodiversity and ecosystem functioning."
Experts in Washington are calling for people to take action now, so the species can be controlled before it becomes out of hand.
Natch!
“Accident” my foot!
One more good reason not to order from China.
Don’t call them “Asian”. You know why. /sarc
Meh. That was a dumb movie.
“Just one sting is enough to kill someone allergic to their venom.”
I believe that is also true of domestic bees already present in this country.
France seems to have all kinds of infestation problems....
Another unwanted gift from China and thereabouts.
The Chinese giant stink bug just invaded Turkey — stowaways on improperly cleaned storage containers — and is destroying the hazelnut crop. Goodbye Nutella.
Its where all the Flu Bros hang out
Note the almond eyes...
Hmmm...does The Sun still have a topless girl on Page 3? They’re into selling papers, that’s for sure.
That’s because France is tolerant, diverse and inclusive! Looking forward to hearing about a new breed of mooselimb bee in France. The bee of pieces.
Ahhh China, is there anything China can’t do?
I’ve had the misfortune of being stung by one of these monsters.
It got me on the left cheek just below the eye.
I looked like I’d been hit by a car.
Zanti Misfits!!
Gonna have to use my shotgun.
