9 Giant hornets headline beekeepers’ concerns
Provincial apiarist updates beekeepers on pests, diseases by TOM WALKER
PRINCE GEORGE – If you want to catch a bee, ask a beekeeper to help. That’s the strategy
provincial apiculturist Paul van Westendorp used when two Asian giant hornets were spotted and captured at a Nanaimo-area apiary in September, and it’s a good thing he did. “This is a totally other
creature,” van Westendorp told delegates to the BC Honey Producers Association annual general meeting in Prince George, October 4-6. “It is the apex insect predator – the ultimate insect hunter. They can destroy a commercial honeybee hive in less than an hour.” Asian giant hornets include a number of insects in the Vespa genus, van Westendorp explains. “The one we saw in Nanaimo, Vespa mandarinia, is a ground-nester,” he says. The hornets raid a colony
by biting and dismembering young bees and then steal the bee brood and turn it into “protein meatballs” to bring back to their nests, van Westendorp continues. “We have full confidence that if they establish themselves in BC, beekeepers will be able to deal with them effectively,” he says. “These insects have an oversize head and you will be able to screen for them.”
it.
But that is not the least of The hornets are also a
threat to livestock and wildlife, not to mention humans. People typically provoke attacks when they unwittingly disturb a nest. “In Japan, there are 40 to 60 human fatalities each year from sting attacks,” van Westendorp says, noting just a few dozen can cause trouble. “Each hornet can sting multiple times and their
venom contains a cytolytic peptide that will cause tissue damage and bleeding.” He says one of the
beekeepers involved in the eradication mission was stung several times through his beekeepers outfit, and there were open wounds on his legs.
Nanaimo beekeepers knew what to do, however. Van Westendorp reached out to them after four additional sightings, aside from at the apiary.
“I contacted them for help
after the sightings, and after confirming with different agencies the insect we were dealing with,” says van Westendorp. “They did a fantastic job.”
The Nanaimo squad mapped where the sightings were, considered the insect’s behaviour, and calculated where to look. “They found the nest in the
forest within a couple of hours,” he says. “It’s a grand story and the beekeepers deserve all the credit.” Some 100 hornets were gassed with CO2 at dusk, dug out of the nest and soaked in alcohol to preserve them. There were drones, but no virgin queens were found, confirming that the nest had not had time to develop to a point that the insects would spread. “That’s not the end of it,”
says van Westendorp, adding that it is suspected they arrived via the port of Nanaimo. “We need to be vigilant in 2020 to make sure that they did not establish themselves,” he says, noting that the climate can’t be counted on to curtail the pests. “I’ve seen nest cone that has been in a fridge for 24 hours and a freezer for 24 hours and the brood were still wiggling.” The rest of van
Westendorp’s report was not as dramatic.
There is little chance of mistaking the Asian giant hornet with domestic hornets. PAUL VAN WESTENDORP PHOTO He says he was happy with
the responses to the province’s annual spring survey that went out to the 403 beekeepers who are registered to have 10 colonies or more.
“We received 155 online
responses for a total of 39% returned, which I consider excellent,” he says. The survey noted 54,000 colonies went into the winter of 2018, with 37,000 surviving
in the spring, for a 32% winter mortality. Van Westendorp says the weather was a key factor in those losses. “We had virtually no winter
