Pesticide resistance is the ability of a pest to survive normally lethal rates of a pesticide. The ability to develop resistance to a wide range of pesticides is a widespread phenomenon among the mites, so it was almost inevitable that varroa would become resistant against the commonly used acaricides such as the pyrethroids, taufluvalinate (Apistan) and flumethrin (Bayvarol). Studies found tha...

In a study replicated across two states and two years, we tested the sublethal effects on honey bees of the miticides Apistan (tau fluvalinate) and Check Mite+ (coumaphos) and the wood preservative copper naphthenate applied at label rates in field conditions. A continuous covariate, a colony Varroa mite index, helped us disambiguate the effects of the chemicals on bees while adjusting for a pr...

Deformed wing virus (DWV) is a pathogenic of honey bees transmitted by the ectoparasitic mite Varroa destructor. Annual overwintering colony losses, accounting for ~25% all colonies, are associated with high levels Varroa-DWV infestation. Effective miticide treatments available to control Varroa. However, absence coordinated treatment means environmental transmission mites continues unchecked. ...

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...

The Asian yellow-legged hornet ( Vespa velutina ) has been invading Italy since 2013, and it was subjected to management programs counter its spread raise awareness about impacts. We administered a questionnaire sample of 358 beekeepers in Italy, asking them their sources information on V. perception potential impacts severity, compared other threats beekeeping. also explored Internet searching...

Voltage-gated sodium channels are essential for the generation and propagation of action potentials in most excitable cells. They are the target sites of several classes of insecticides and acaricides. Isolation of full-length sodium channel cDNA is a critical and often difficult step toward an understanding of insecticide and acaricide resistance. We previously cloned and sequenced two overlap...
