GONZALEZ-ACUNA, Daniel et al. Comparison of formic acid and fluvalinate effectiveness, as control methods of Varroa destructor (Acari:Varroidae) in Apis mellifera (Hymenoptera: Apidae), in Ñuble, southcentral Chile. Rev. Soc. Entomol. Argent. [online]. 2005, vol.64, n.3, pp.35-42. ISSN 0373-5680.
ABSTRACT. During spring of 2000, formic acid (85 %) and fluvalinate (3%) effectiveness against Varroa destructor Anderson y Trueman, was compared in Apis mellifera L. colonies located at Chillán Campus of University of Concepción (36º36' S - 72º0,6´O). Three groups of 10 beehives were formed. Group 1 was treated with formic acid to 85 %, applied in Universal Evaporator MHT®. Group 2 was used as control, without receiving any treatment. Group 3 was treated with fluvalinate 3% (rever concentración) impregnated splints. At the end of treatment, all colonies received a test treatment with Bayvarol® (Flumetrina). The biggest effectiveness was in fluvalinate treated group, with an average of 98.05 ± 2.13 %. In formic acid treated group an average effectiveness of 88.26 ± 9.12% was obtained, while in the control group the natural mortality was 41.11 ± 11.52 %.
