          Abstract

          Abstract In order to determine biometric parameters of newborn drones of Apis mellifera L. and factors that affect them, a study was conducted in three apiaries from San José de las Lajas municipality, which included a monthly sampling of 10 hives/apiary, in November and December, 2015 and in January, 2016. An amount of 50 newborn individuals were examined, and their birth weight and body length were determined, as well as their fore right wing and body color. Infestation extension and intensity by Varrea destructor was evaluated. Weight and dimensions of drones were in correspondence with those of European breeds, and were influenced by the apiary of origin, sampling month and intensity of infestation.

          Resumen Para determinar los parámetros biométricos de los zánganos de Apis mellifera L. al nacer y los factores que los afectan, se desarrolló un estudio en tres apiarios del municipio San José de las Lajas, que comprendió un muestreo mensual de 10 colmenas/apiario en noviembre y diciembre de 2015 y en enero de 2016. En cada colmena se examinaron 50 individuos al nacer, a los que se les determinó el peso en el nacimiento, la longitud del cuerpo y del ala anterior derecha y el color. Se precisó la extensión e intensidad de invasión por Varroa destructor. El peso y las dimensiones de los zánganos coincidieron con los de razas europeas, y en ellos influyó el apiario de procedencia, mes de muestreo e intensidad de infestación.

            Biology and control of Varroa destructor.

            The ectoparasitic honey bee mite Varroa destructor was originally confined to the Eastern honey bee Apis cerana. After a shift to the new host Apis mellifera during the first half of the last century, the parasite dispersed world wide and is currently considered the major threat for apiculture. The damage caused by Varroosis is thought to be a crucial driver for the periodical colony losses in Europe and the USA and regular Varroa treatments are essential in these countries. Therefore, Varroa research not only deals with a fascinating host-parasite relationship but also has a responsibility to find sustainable solutions for the beekeeping. This review provides a survey of the current knowledge in the main fields of Varroa research including the biology of the mite, damage to the host, host tolerance, tolerance breeding and Varroa treatment. We first present a general view on the functional morphology and on the biology of the Varroa mite with special emphasis on host-parasite interactions during reproduction of the female mite. The pathology section describes host damage at the individual and colony level including the problem of transmission of secondary infections by the mite. Knowledge of both the biology and the pathology of Varroa mites is essential for understanding possible tolerance mechanisms in the honey bee host. We comment on the few examples of natural tolerance in A. mellifera and evaluate recent approaches to the selection of Varroa tolerant honey bees. Finally, an extensive listing and critical evaluation of chemical and biological methods of Varroa treatments is given. This compilation of present-day knowledge on Varroa honey bee interactions emphasizes that we are still far from a solution for Varroa infestation and that, therefore, further research on mite biology, tolerance breeding, and Varroa treatment is urgently needed.

              Colonización, impacto y control de las abejas melíferas africanizadas en México

              En este trabajo recapitulativo se describe el proceso de colonización y reemplazo de las poblaciones de abejas melíferas europeas por africanizadas, así como las características biológicas que han dado ventajas a las abejas africanizadas para su éxito colonizador y una discusión sobre su impacto, control y perspectivas para la apicultura mexicana, abordando el punto de vista de los apicultores respecto a su manejo y explotación en comparación con abejas europeas.
