The ectoparasitic mite Varroa destructor remains a great threat for the beekeeping industry, example contributing to excessive winter colony loss in Canada. For decades, beekeepers have sequentially used registered synthetic varroacides tau-fluvalinate, coumaphos, amitraz, and flumethrin, leading risk of resistance evolution mites. In addition widespread coumaphos pyrethroids, decline amitraz efficacy has recently been reported numerous regions goals this study were assess Canadian...
The honey bee, Apis mellifera L., is the world's most important managed pollinator of agricultural crops, however, Varroa mite, destructor Anderson and Trueman, infestation has threatened bee survivorship. Low efficacy development mite resistance to currently used Varroacides increased demand for innovative, effective treatment tool options that exhibit high efficacy, while minimizing adverse effects on fitness. In this investigation, toxicity 16 active ingredients 9 formulated products...
Nosema ceranae Fries, 1996, causes contagious fungal nosemosis disease in managed honey bees, Apis mellifera L. It is associated around the world with winter losses and colony collapse disorder. We used a laboratory vivo screening assay to test curcumin, fenbendazole, nitrofurazone ornidazole against N. bees identify novel compounds anti-nosemosis activity compared commercially available medication Fumagilin-B®. Over 20-day period, Nosema-inoculated Plexiglas cages were orally treated...
The objective of this study was to assess the effectiveness a cooperative breeding program designed enhance winter survival honey bees ( Apis mellifera L.) when exposed high levels varroa Varroa destructor Anderson and Trueman) in outdoor-wintered indoor-wintered colonies. Half colonies from selected unselected stocks were randomly assigned be treated with late autumn oxalic acid treatment or left untreated. Colonies then wintered either indoors n = 37) outdoors 40). Late did not improve...
The Varroa mite (Varroa destructor) is an ectoparasite that can affect the health of honey bees (Apis mellifera) and contributes to loss colony productivity. limited availability Varroacides with different modes action in Canada has resulted development chemical resistance populations. Therefore, urgent need evaluate new potential miticides are safe for exhibit high efficacy against exists. In this study, acute contact toxicity 26 active ingredients (19 classes), already available on market,...

Varroa destructor Anderson and Trueman, is an ectoparasitic mite of honey bees, Apis mellifera L., that has been considered a major cause colony losses. Synthetic miticides have developed registered to manage this ectoparasite, however, resistance pyrethroid organophosphate Varroacides already reported in Canada. To test toxicity miticides, current contact-based bioassay methods are designed evaluate mites bees separately, these unlikely give accurate depiction how interact at the level....
Abstract BACKGROUND Varroa mite, destructor , is a major threat for honey bee, Apis mellifera colonies. Beekeepers have used synthetic Varroacides against mite decades, but resistance to organophosphates, pyrethroids and formamidine has been reported in many locations worldwide. The goals of this study were develop reliable bioassay assess efficacy phenotypic commercial Varroacides. In study, was evaluated using the Apiarium technique comparison Mason jar method. RESULTS Among tested...
