“…However, these miticides leave chemical residues in wax and honey (Wallner 1995;Cabras et al 1994). Other chemical control agents such as Xumethrin, amitraz, cymiazole, and bromopropylate are also associated with toxic residues (Wallner 1995;Gamber 1990), as such, they are diYcult to register in North America.…”

Strips coated with conidia of Metarhizium anisopliae (Metschinkoff; Deuteromycetes: Hyphomycetes) to control the parasitic mite, Varroa destructor (Anderson and Trueman) in colonies of honey bees, Apis mellifera (Hymenoptera: Apidae) were compared against the miticide, tau-fluvalinate (Apistan) in field trials in Texas and Florida (USA). Apistan and the fungal treatments resulted in successful control of mite populations in both locations. At the end of the 42-day period of the experiment in Texas, the number of mites per bee was reduced by 69-fold in bee hives treated with Apistan and 25-fold in hives treated with the fungus; however mite infestations increased by 1.3-fold in the control bee hives. Similarly, the number of mites in sealed brood was 13-fold and 3.6-fold higher in the control bee hives than in those treated with Apistan and with the fungus, respectively. Like the miticide Apistan, the fungal treatments provided a significant reduction of mite populations at the end of the experimental period. The data from the broodless colonies treated with the fungus indicated that optimum mite control could be achieved when no brood is being produced, or when brood production is low, such as in the early spring or late fall. In established colonies in Florida, honey bee colony development did not increase under either Apistan or fungal treatments at the end of the experimental period, suggesting that other factors (queen health, food source, food availability) play some major role in the growth of bee colonies. Overall, microbial control of Varroa mites with fungal pathogens could be a useful component of an integrated pest management program for the honey bee industry.

“…The most effective and widely used acaricides to control Varroa are with the pyrethroid class of insecticide tau-fluvaliniate and with the organophosphate coumaphos. However, coumaphos and fluvalinate have been detected in wax and honey (Cabras et al, 1994;Wallner, 1995;Jimenez et al, 2005), which is a threat to the food chain for humans and compromising food and cosmetic sources. Other chemical acaricides such as flumethrin, amitraz, cymiazole, and bromopropylate are also associated with toxic residues (Gamber, 1990;Wallner, 1995).…”

“…The application of acaricides in the control of the bee ectoparasite is accompanied by negative side effects on the bees themselves, beekeepers and/or bee product consumers. An additional problem is the resistance which often develops towards synthetic acaricides (Milani, 1999;Elzen et al, 1999 The aforementioned led to the use of an increasing number of acaricides with various mechanisms of action and, consequently, to considerable residua in bee products (Cabras et al, 1994;Bogdanov, 1998;Wallner 1999;Lodesani, 2008) and negative effects on bee colonies (Patetta andManino, 1988, Rada et al, 1997;Pettis et al, 2004a). Fluvalinat, for example, significantly increases the mortality in bees and reduces the number of aerobic bacteria in their digestive system, whilst amitraz stimulates the proliferation of yeasts (Rada et al, 1997).…”

The aim of this work was the investigation on the efficacy of pulverised sugar dusting on knocking-down Varroa destructor mites and the influence of the dynamics of the treatment on the degree of infestation in honey bee colonies. Two methods were deployed to measure the degree of infestation of bee colonies with V. destructor mites: the sugar shake method and the technique which involves mesh bottom boards equipped with sticky inserts. The research was carried out on 30 strong honey bee colonies in three successive years. The results proved that dusting with pulverised sugar (particle diameter below 40 μm) influenced the fall of V. destructor in comparison with both their fall off prior to the treatment and the negative control. The most discernible effects on the mite fall and the decline in their population in the hives was obtained with dustings repeated at threeday intervals. To conclude, the dynamics of the treatment affected the degree of infestation in bee colonies. However, the efficacy of sugar dusting was significantly lower in comparison with the one of flumethrin (positive control). Thus, in spite of considerable favourable effects on the decline in the degree of infestation with mites, by no means may dusting with pulverised sugar be advised to beekeepers as the one and only means of bee protection against V. destructor. The use of the technique which involves mesh bottom boards equipped with sticky inserts proved more efficacious and sensitive in the judgment of the degree of infestation of bee colonies in comparison with the sugar shake method, which includes dusting 300 bees with 40 g of pulverised sugar (particle diameter below 40 μm)
