US Magazin Science published in 1989 a report prepared by a french scientist group working in Labs for neurobiology in Bures-sur-Yvette. As explained in the report they use Ethylpalmitat and Methyllinolenat as active substances to allure varoa into a trap and subsequently eliminate them from the hive. The cheap and undengerous (for bees and human) substance, its uncomplicated application looked very attractive and promissing. Since then I never heared any further news on development of this approach to get ride of varoa.Does somebody of the BEELIST community has perhaps more up-to-dayt or fresh info?
