Behavioral defenses of honey bees against Varroa jacobsoni Oud . Otto
Two behaviors of honey bees, hygienic behavior and grooming, are mechanisms of defense against brood diseases and parasitic mites. Studies have shown that Apis mellifera colonies remove worker brood infested with Varroa jacobsoni mites from the nest (hygienic behavior), and groom the mites off other adult bees, but to a limited extent compared to the original host of V. jacobsoni, A. cerana. Re...
متن کاملA comparative study of Varroa jacobsoni reproduction inworker cells of honey bees
The aim of this study was to investigate an underlying mechanism of the apparent tolerance of Africanized honey bees (AHB) to Varroa jacobsoni mites in Mexico. This was achieved by conducting the first detailed study into the mites’ reproductive biology in AHB worker cells. The data was then compared directly with a similar study previously carried out on European honey bees (EHB) in the UK. A ...

متن کاملThe kairomonal esters attractive to the Varroa jacobsoni mite in the queen brood
are secreted by queen brood at half the rate found for worker brood. Methyl oleate, repellent to the mite, is secreted in large amounts compared with the attractive esters. Quantitative and qualitative differences in the esters present on worker, drone, and queen broods could partially explain the weaker attraction exerted by queen brood on the mite, compared with the attractive effects of work...
متن کاملThe transmission of deformed wing virus between honeybees (Apis mellifera L.) by the ectoparasitic mite varroa jacobsoni Oud
Under field conditions, Varroa jacobsoni were shown to be highly effective vectors of deformed wing virus (DWV) between bees. Adult female mites obtained from honeybee pupae naturally infected with DWV contained virus titers many times in excess of those found in their hosts and, beyond that, which might be expected from a concentration effect. It is therefore possible that DWV may be capable o...
