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 کاملCombating Varroa destructor in Honeybee Colonies Using Flumethrin or Fluvalinate
Gregorc A. , M. I . Smodi‰ ·kerl : Combating Varroa destructor in Honeybee Colonies Using Flumethrin or Fluvalinate. Acta Vet. Brno 2007, 76: 309-314. Mite mortality in two apiaries, one with 32 and the other with 15 honeybee (Apis mellifera carnica) colonies, was recorded prior to and after flumethrin or fluvalinate treatments and after a control, oxalic-acid application. During the 42and 51-d...
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 کاملDevelopment of Varroa jacobsoni in colonies of Apis mellifera capensis and Apis mellifera carnica
Honey bee colonies (Apis mellifera carnical, infested with Varroa jacobsonl were de-queened and divided into 2 subunits. Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen. The development of the mite population was monitored by determining the number of mites in samples of brood, and worker bees, and lhe number of dead mites on the bottom board of the h...
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...
