MARCANGELI, Jorge Augusto  e  GARCIA, María del Carmen. Control of Varroa destructor (Mesostigmata: Varroidae) in honeybee colonies of Apis mellifera Hymenoptera: Apidae) by means of different active agents. Rev. Soc. Entomol. Argent. [online]. 2003, vol.62, n.3-4, pp.69-74. ISSN 0373-5680.

The aim of this work was to evaluate the acaricide efficacy of four commercial products against the mite Varroa destructor (Anderson & Trueman) in honeybee colonies of Apis mellifera (L.). Twenty five honeybee colonies divided in five equal groups were selected. Groups received Apistan®, Bayvarol®, Apitol® and Folbex®. Final group was the control. Dead mites were collected weekly in special floors. After treatment, each colony received a shock treatment with the other three products to kill remnant mites and to obtain acaricide efficacy. Average values of efficacy were Apistan® 85,38%, Bayvarol® 83,83%, Apitol® 71,77% and Folbex® 62,78%. In all cases these values were lower than those reported by the laboratories that produce them. These results alert about the possible generation of resistant mite populations and justify research directed to search for alternative products for the control this parasite.
