Dear Bee-listers... I am Eduardo Varni from Argentina and I own hives here. Since two years ago the production decresed 30% due one hornet who killed bees(Its scientific name is Mallophora Ruficauda).It hunt the bees on flight and at the same time it produce a frightening hum. This noise makes the bees remain in their hives. The female hornet laid his eggs on the low branches of trees and /or on wires of the fences .When the larvae are born,they fall to the ground and buried themselves .There, they await for soil worms to parasite during the winter.Then they reborn in summer as a killer hornet. This predator eats all kind of insects ,specially bees. We began a survey to fight against this predator, so we wish to receive same information or experiences about control methods ,sexuan Pheromones isolation or something else . Thanks in advance for your help. Regards *********************************** * * * Eduardo Varni * * [log in to unmask] * ***********************************
