Biologists have developed a solution for controlling the invasive Asian hornet Vespa velutina based on the insect’s natural chemical mating instincts. They deciphered the sex pheromone of the insect and devised a method of luring males into traps baited with synthesized versions of the pheromones. Vespa velutina has recently spread its presence with invasions in Europe and Korea, posing risks to honey bees, humans and related economics.
