Varroa destructor reproductive success is considered an important character for determining the resistance of honey bees to this mite parasite. However, most of the published data are not comparable due to the different methods of ascertaining and reporting reproduction. A recently published technique that involves reconstructing mite families in older worker brood gives repeatable and reliable...

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. ...

this research explains the morphometric characteristics of varroa destructor anderson and trueman in tehran province. 180 adult female mites were collected from three different colonies of apis mellifera l. in three apiaries during september 2003 to may 2004. these colonies were divided according to three altitudes-less than 1000m, 1000-1500m and more than 1500m above the sea level. the morphol...

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...

An obvious need for an updated and comprehensive study prompted this investigation of the complex of environmental costs resulting from the nation’s dependence on pesticides. Included in this assessment of an estimated $10 billion in environmental and societal damages are analyses of: pesticide impacts on public health; livestock and livestock product losses; increased control expenses resultin...

The ectoparasitic mite, Varroa destructor, has become the largest threat to apiculture and honey bee health world-wide. Since it was introduced to the new host species, the European honey bee (Apis mellifera), it has been responsible for the near complete eradication of wild and feral honey bee populations in Europe and North America. Currently, the apicultural industry depends heavily on chemi...
