Continuous Management of Varroa Mite in Honey Bee, Apis Mellifera, Colonies
The Varroa mite has many deleterious impacts on honey bee colonies. These impacts are well known and include, for example, the weakness of honey bees by feeding on the haemolymph (Rosenkranz et al. 2010), transportation of viruses to host bees including Kashmir bee virus (Chen et al. 2004), suppresses the immunity of honey bees (Shen et al. 2005), impact bee wing Shape (Cakmak et al. 2011) and ...
متن کاملControl of Varroa Mite by Essential Oils and Formic Acid with Their Effects on Grooming Behaviour of Honey Bee Colonies
Four essential oils in two concentrations (50 and 100%) of thyme, Thymus vulgaris; Cinnamon, Cinnamomum zeylanicum; Lemon grass, Cymbopagon flexuosus; Anise, Pimpinella anisum and formic acid (65%) were used against varroa mite, Varroa destructor infesting honey bee colonies. Results show that, formic acid and the highest concentration (100%) of tested essential oils caused effective control of...
متن کاملAPICULTURE AND SOCIAL INSECTS Varroa destructor Infestation in Untreated Honey Bee (Hymenoptera: Apidae) Colonies Selected for Hygienic Behavior
Honey bee (Apis mellifera L.) colonies bred for hygienic behavior were tested in a large Þeld trial to determine if they were able to resist the parasitic mite Varroa destructor better than unselected colonies of “Starline” stock. Colonies bred for hygienic behavior are able to detect, uncap, and remove experimentally infested brood from the nest, although the extent to which the behavior actua...
متن کاملRussian honey bee (Hymenoptera: Apidae) colonies: Acarapis woodi (Acari: Tarsonemidae) infestations and overwintering survival.
Honey bee, Apis mellifera L. (Hymenoptera: Apidae), colonies infested by parasitic mites are more prone to suffer from a variety of stresses, including cold temperature. We evaluated the overwintering ability of candidate breeder lines of Russian honey bees, most of which are resistant to both Varroa destructor Anderson & Trueman and Acarapis woodi (Rennie), during 1999-2001. Our results indica...
متن کاملDifferential gene expression of two extreme honey bee (Apis mellifera) colonies showing varroa tolerance and susceptibility.
Varroa destructor, an ectoparasitic mite of honey bees (Apis mellifera), is the most serious pest threatening the apiculture industry. In our honey bee breeding programme, two honey bee colonies showing extreme phenotypes for varroa tolerance/resistance (S88) and susceptibility (G4) were identified by natural selection from a large gene pool over a 6-year period. To investigate potential defenc...
