Varroasis of the bee Apis mellifera is considered the plague that causes greater economic impact on the beekeeping world. There is a need to investigate new control alternatives and expand the range of products that offer the possibility of alternating chemical treatments with organic acids or essential oils. For the above, was determined the effectiveness of acaricides: oxalic acid, amitraz, cumaphos and thymol in the control of Varroa destructor and its possible side effects in the colonies of bees Apis mellifera L. This study was conducted in the Apiary of the National Agrarian University Molina (UNALM). Twenty European bee colonies, Apis mellifera L. were used. The experimental phase was conducted from October to November 2015, for which the design was completely randomized with four treatments and one control with four replications. Treatment one (T1) consists of a mixture of 2.5 g of oxalic acid in 40 g of powdered sugar per hive, three applications every eight days. Treatments two (T2) and three (T3) consisted of two comercial strips application based on amitraz and coumaphos respectively; treatment four (T4) was assigned to the witness. Treatment five (T5) consisted of the application of 8 g of thymol diluted in 8 ml of alcohol, divided equally into two squares of oasis (absorbent sponge), with three applications every eight days. The effectiveness of acaricides was determined in two ways; the first, according to the difference between the percentages of initial and final infestation in adult bees, which coumaphos and thymol reached the highest value of 94.85 and 84.68 percent respectively; and second, taking into account the number of varroa falls per treatment and the total number of varroa falls by treating chemical shock, wherein coumaphos and thymol reached the highest value of 97.72 and 87.16 percent, respectively. Coumaphos and thymol showed a fall dynamics varroa similarly proving more important to day 13 of experiment. Acaricide showed no side effects on bees.
