The susceptibility of Varroa destructor against oxalic acid: A study case

Varroa destructor Anderson et Trueman is an ectoparasitic mite of the honey bee Apis mellifera L. and it must be controlled in managed bee colonies to maintain colony health. Taking into account that these mites are now resistant to synthetic acaricides worldwide, oxalic acid was suggested as an alternative for Varroa control. Oxalic acid is one of the most common natural miticides used against varroosis by spraying and sublimation administration techniques. It is a natural constituent of honey, very active against the Varroa mite, safe to use for beekeepers, and has no residue problems. Nevertheless, some authors have predicted that the risk of developing resistance to oxalic acid in mites is high. The objective of this research was to assess the susceptibility to oxalic acid of a V. destructor population belonging to a commercial apiary where 64 consecutive control treatments with this acid were performed. Bioassays to assess the oxalic acid susceptibility were performed on two mite populations: (1) a „focal‟ population consisting of mites previously exposed to oxalic acid treatments, and (2) a „naïve‟ population that was never exposed to this acid, which allows setting a reference in the absence of historical data on our „focal‟ mites. The results reported here suggest that the Varroa population exposed during 8 successive years to oxalic acid treatments remains susceptible to this acid.Fil: Maggi, Matías Daniel.

A new formulation of oxalic acid for Varroa destructor control applied in Apis mellifera colonies in the presence of brood

International audienceAbstractAn organic product based on oxalic acid was evaluated for use in Varroa control under spring/summer climatic conditions in Argentina. The formulation consists of four strips made of cellulose impregnated with a solution based on oxalid acid. Forty-eight beehives were used to assess the product efficacy. Residues of the product were also tested in honey, bees, and wax. Each trial had respective control groups without oxalic treatment. At the beginning of the experiment, four strips of the formulation were applied to the colonies belonging to the treated group. Falling mites were counted after 7, 14, 21, 28, 35, and 42 days. After the last count, the strips were removed and colonies received two flumethrin strips for 45 days. Falling mites were counted throughout this period. Average efficacy of the organic product was 93.1 % with low variability. This product is an organic treatment designed for Varroa control during brood presence and represents a good alternative to the synthetic treatments
