Synergistic strategies as an alternative for the control of varroasis in africanized bees
This work investigates the synergistic effect of combining flumethrin (Bayvarol) strips of polyethylene, formic acid (FA), the biotechnical method of the change of the queen bee and their possible combinations, to control Varroasis in the africanized honey bees. The formic acid was dispersed by means of a homemade device. Two experiments were done in two regions of Chiapas, Mexico. In a semiwarm zone and in a hot zone. The experiments took four weeks and the results show that in Altamirano for the period of time from April 15th to the 11th of May 1998, the combination of flumethrin with the change of the queen bee and only the flumethrin, produced a significant reduction of the infestation in the treated colonies, which showed medium to high infestations. In contrast the formic acid did not prove in any case to be the method most efficient. In Tapachula during the period from July 4th to August 2nd 1998 none of the utilized treatments had an effect on the infestations of varroa and the hoped for synergistic effect was not obtained. Even so, noting that the initial colonies with low and medium infestation and the control treatments in the time period of the experiments, showed decreases in the infestations. So, it can be foreseen as a latent lines of investigation the characteristic of tolerance in the African bees to the Varroa jacobsoni Oud. mites in these zones.
