The objective of the present study was to evaluate the best alternative of two oxalic acid methods (spraying and strips of cellulose) for the control of Varroa destructor in colonies of Apis mellifera under summer/ottom climatic conditions in Cieneguilla by the parameters: effectiveness based on the difference in infestation in adult bees; effectiveness based on the number of fallen mites due to the application of a chemical shock treatment; differences between the initial and final amount of brood combs and food reserve and economic and practical evaluation of the treatments. Twenty-seven hives of honeybees naturally infested with varroa were evaluated during the period from February to March 2022, which were grouped into 2 treatments with 10 repetitions and a control group with 7 repetitions. Treatment 1 (T1) consisted in spraying 50 ml of solution per hive with a second application after 14 days. The solution was prepared using one kilogram sucrose per one liter of water and 80 g of oxalic acid crystals. Treatment 2 (T2) consisted in placing four strips made of cellulose, each one contains 1 g of OA mixed with 5 mL of glycerin and finally the control group, it didn’t receive oxalic acid application. All the treatments were suspended after 28 days, immediately, a fluvalinate treatment was applied on both treatments and the control. After 2 weeks, efficacy of the treatment in varroa control was determined by comparing the number of falling mites recorded during the oxalic acid treatment period with the total number of falling mites recorded during the whole trial (including the fluvalinate treatment). Pulverized method and cellulose strips method achieved 73.15 and 54.97 percent respectively. The effectiveness through the infestation difference modality in adult bees was higher for the pulverized treatment (71.82 percent), while the treatment with cellulose strips obtained 46.98 percent. There were no adverse effects regarding the difference in the number of brood combs and food reserve; Finally, the spray method turned out not to be the most practical, but it was the most effective and economical, since its cost was less than 0.21 soles per hive.
