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...

Acaricide (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...

Biology 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 ...

Applications of plane-wave destructor filters

On several synthetic and real-data examples, I show that finite-difference plane-wave destructor filters can be a valuable alternative to prediction-error filters in applications such as data interpolation, fault detection, and noise attenuation.
