Journal ArticleDOI
From field to food—will pesticide-contaminated pollen diet lead to a contamination of royal jelly?
TL;DR: Considering this extraordinary low contamination of RJ, it seems unlikely that pesticides, if used according to the approved application instructions, would impair the development and health of honeybee queens.
Journal ArticleDOI
Invasion of Varroa destructor mites into mite-free honey bee colonies under the controlled conditions of a military training area
TL;DR: It is shown that highly infested honey bee colonies present a substantial risk to already treated colonies up to distances of 1.5 km away, and a more benign behaviour should be an adaptive strategy for V. destructor.
Journal ArticleDOI
Cuticular volatiles, attractivity of worker larvae and invasion of brood cells by Varroa mites. A comparison of Africanized and European honey bees.
TL;DR: In this paper, a comparison of brood infestation rates and brood attractiveness to Varroa destructor mites was performed in a laboratory bioassay where either living host stages were offered or host extracts were presented on dummies.
Journal ArticleDOI
Volatiles of the honey bee larva initiate oogenesis in the parasitic mite Varroa destructor
Peter Rosenkranz,Claudia Garrido +1 more
TL;DR: A new bioassay is presented for field and laboratory tests to evaluate host factors triggering Varroa oogenesis and the activating components apparently are in the polar fraction of the cuticular volatiles.
Journal ArticleDOI
Scent or movement of Varroa destructor mites does not elicit hygienic behaviour by Africanized and Carniolan honey bees
Pia Aumeier,Peter Rosenkranz +1 more
TL;DR: Le comportement hygienique des abeilles domestiques (Apis mellifera L.) est connu comme moyen efficace de defense contre la loque americaine and d'autres maladies du couvain dans la tolerance a l'acarien Varroa destructor.
