“…Positive correlations between number of mites on bottom boards with amount and emergence of brood have been reported (Lobb and Martin, 1997;Beetsma et al, 1999). However, there were no differences in the number of combs with bees and with brood between our two groups of colonies.…”

“…Hence, there is no clear evidence from this study that the Bee Gym increases mite fall through enhanced grooming by the bees. The presence of brood has a large effect on mite fall (Branco et al, 2006;Lobb & Martin, 1997). When brood is present, the majority of mites on drop boards are those associated with emerging brood (Lobb & Martin, 1997), with hygienic behavior and phoretic mites making up the remainder.…”

“…(2) The treatment was randomised separately for four hives at IM that had low mite fall (again with equal numbers assigned control/treatment). The counting was performed blind with respect to which hives had the Bee Gyms or Brood presence/absence was recorded for all colonies during the trial, as this can have significant effects on mite fall (Branco, Kidd, & Pickard, 2006;Lobb & Martin, 1997). As six colonies had brood absent for a portion of the trial, these were removed from the analyzes, leaving the final 20 colonies that completed the trial.…”

Grooming is a honey bee behavior that has the potential to minimize and manage the detrimental effects of Varroa destructor. Here we tested the efficacy of the Bee Gym™, a device hypothesized to increase honey bee auto-grooming and increase mite removal from colonies. Natural mite fall from 20 colonies was counted for 14 days, after which half the colonies were fitted with a Bee Gym and half with a control object. Mite fall and the proportion of damaged mites were then recorded for another 14 days. Total mite fall was generally higher over the second 14 days, but this increase was not significantly higher for the Bee Gym colonies than for the control colonies. There was also no difference in the proportion of damaged mites between the two treatments. Mite fall and damage to mites may be influenced by other factors, and this is discussed; however, given that we found no effect of the Bee Gym, we conclude that there is no evidence from this study of its efficacy as a management strategy for V. destructor.Efecto del dispositivo de aseo 'Bee Gym ™' sobre la caída del ácaro Varroa destructor en colonias de abejas melíferas (Apis mellifera) El aseo es un comportamiento de la abeja de la miel que tiene el potencial de minimizar y de manejar los efectos perjudiciales de Varroa destructor. Aquí hemos probado la eficacia del Bee Gym ™, un dispositivo que hipotéticamente aumenta el auto-aseo en la abeja de la miel y aumentar la eliminació n de ácaros de las colonias. La caída natural de ácaros de 20 colonias se contó durante 14 días, tras lo cual la mitad de las colonias fueron equipadas con un Bee Gym y la otra mitad con un objeto de control. La caída de ácaros y la proporció n de ácaros dañados se registraron durante otros 14 días. La caída total de ácaros fue generalmente mayor durante los segundos 14 días, pero este aumento no fue significativamente mayor para las colonias con Bee Gym que para las colonias de control. Tampoco hubo diferencias en la proporció n de ácaros dañados entre los dos tratamientos. La caída de ácaros y el daño a los ácaros pueden estar influidos por otros factores, lo cual se discute; sin embargo, dado que no encontramos ningún efecto del Bee Gym, concluimos que no hay evidencia en este estudio de su eficacia como estrategia de manejo para V. destructor.

“…Lobb and Martin (1997) estimated that around 50% of fallen dead mites die within sealed brood cells, the rest mainly shortly after emergence. This may explain Wallner's deduction that if 60% of fallen mites show damage inflicted by bees, those bees should be capable of survival without mite treatment (Dews, 2008;Wallner, 1990aWallner, , 1990b.…”

Grooming by honey bees as a component of varroa resistant behavior

Grooming behavior of honey bees can be considered in two major categories: autogrooming or self-grooming and inter-bee grooming, called allogrooming. Allogrooming can be one-on-one, or social, involving several nestmates acting collaboratively. In addition, some house bees become allogrooming specialists, and for them grooming their nestmates can be a full-time occupation for most of their lives. Early observations on the Eastern honey bee, Apis cerana, recorded autogrooming, one-on-one, and social allogrooming, all of which result in dead, visibly mutilated varroa mites falling to the hive floor. Similar behavior has been sought in the Western honey bee. Apis mellifera, with variant observations for the different subspecies. Most descriptions relate to A. m. carnica, some to A. m. ligustica, but with one notable exception, almost none to A. m. mellifera. The most impressive findings are from "Africanized" bees, which provide some of the best cases of natural, long-lasting tolerance to varroa mites in A. mellifera, although even some of these are controversial. The speed of both autogrooming and allogrooming responses is generally reported to be much slower in A. mellifera than in A. cerana, and the frequency and degree of damage to mites are also lower. Serious damage, such as severance of limbs and gashes of the idiosoma, shows a heritability (h²) of around .16 in A. mellifera overall.Acicalamiento de las abejas como un componente del comportamiento de resistencia a varroa La conducta de acicalamiento de las abejas puede ser considerada en dos categorías principales: autogrooming o auto-aseo y cuidado personal inter-abeja, llamada allogrooming. Allogrooming puede ser uno-a-uno, o social, incluyendo la participació n de varias compañeras de la colonia que actúan en colaboració n. Además, algunas abejas de interior se convierten en especialistas en el allogrooming, y para ellas el aseo de sus compañeras de colonia puede ser una ocupació n a tiempo completo durante la mayor parte de sus vidas. Las primeras observaciones sobre la abeja de la miel oriental, Apis cerana, registraron autogrooming, uno-a-uno y allogrooming social, todo lo cual resultó en ácaros varroa muertos, visiblemente mutilados caídos en al suelo de la colmena. Se ha buscado un comportamiento similar en la abeja occidental de la miel, Apis mellifera con observaciones variables en las diferentes subespecies. La mayoría de las descripciones se refieren a A. m. carnica, algunas a A. m. ligustica, pero casi ninguna a A. m. mellifera. Los hallazgos más impresionantes son de abejas "africanizadas", que proporcionan algunos de los mejores casos de tolerancia natural de más larga duració n a los ácaros varroa en A. mellifera, aunque incluso algunos de ellos son controvertidos. La velocidad de las respuestas tanto autogrooming como allogrooming está resultando ser mucho más lenta en A. mellifera que en A. cerana, así como la frecuencia y el grado de daño a los ácaros que también son más bajos. Daños graves tales como ruptura de las extremidades y heridas d...
