Field efficacy of acaricides against Varroa destructor
Field trials were conducted in Northeast Spain (Aragón) to evaluate the effectiveness of two acaricides against Varroa destructor. These experiments took into account the season of the year, apiary, colony, and developmental state and strength of the colony. The acaricides used were a synthetic (amitraz, Apivar®) and a natural (formulated from Api Life Var®, thymol oil and thymol alcohol) produ...
متن کاملPropolis chemical composition and honeybee resistance against Varroa destructor.
Propolis is known as honeybee chemical defence against infections and parasites. Its chemical composition is variable and depends on the specificity of the local flora. However, there are no data concerning the relationship between propolis chemical composition and honeybee colony health. We tried to answer this question, studying the chemical composition of propolis of bee colonies from an api...
متن کاملBiology and control of Varroa destructor.
The ectoparasitic honey bee mite Varroa destructor was originally confined to the Eastern honey bee Apis cerana. After a shift to the new host Apis mellifera during the first half of the last century, the parasite dispersed world wide and is currently considered the major threat for apiculture. The damage caused by Varroosis is thought to be a crucial driver for the periodical colony losses in ...
متن کاملBidirectional Transfer of RNAi between Honey Bee and Varroa destructor: Varroa Gene Silencing Reduces Varroa Population
The mite Varroa destructor is an obligatory ectoparasite of the honey bee (Apis mellifera) and is one of the major threats to apiculture worldwide. We previously reported that honey bees fed on double-stranded RNA (dsRNA) with a sequence homologous to that of the Israeli acute paralysis virus are protected from the viral disease. Here we show that dsRNA ingested by bees is transferred to the Va...
متن کاملAcaricide (pyrethroid) resistance in Varroa destructor
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...
