“…In Argentina, where brood was pin killed instead of freeze killed, colonies initially removed 66% of their dead brood in 24 h (Palacio et al 2000), although pin killing results in more rapid removal of brood than freeze killing (Spivak and Downey 1998). While some bee populations from Africa (Fries and Raina 2003;Kamel et al 2003) and the Russian far-east (de Guzman et al 2002) appear to have higher endemic levels of hygienic behaviour, the population we studied appeared similar to the majority of European origin previously studied. Given the similarities, it is possible that other European-derived honeybee populations confront a similar challenge with low heritability.…”

Breeding for hygienic behaviour in honeybees (Apis mellifera) using free-mated nucleus colonies

Gains in hygienic behaviour based on maternal selection of queens were evaluated among four commercial beekeeping operations in northern Alberta, Canada over four generations. While the proportion of breeding colonies expressing the trait increased with each subsequent generation, levels of hygienic behaviour among progeny remained relatively unchanged. Estimated breeding values for the final generation of progeny confirmed only a slight effect of selection; the expected average increase in the removal of frozen brood in the next generation was determined to be 0.17% at 24 h and 0.34% at 48 h. This modest increase may be explained by the low (24 h, h 2 =0.17) to moderate (48 h, h 2 =0.25) heritability of hygienic behaviour in our population. Our work implies that year-to-year comparisons of breeding colonies may not be an accurate predictor of selection gains within honeybee populations and that honey producers in this region may need to focus selection within elite breeding populations.

“…Russian honey bees are known to be hygienic toward freeze-killed brood (de Guzman et al 2002). However, it is uncertain whether the Russian honey bee colony we used as a host was also hygienic toward varroa-infested brood.…”

A high proportion of nonreproductive (NR) Varroa destructor Anderson & Trueman (Mesostigmata: Varroidae), is commonly observed in honey bee colonies displaying the varroa sensitive hygienic trait (VSH). This study was conducted to determine the influence of brood removal and subsequent host reinvasion of varroa mites on mite reproduction. We collected foundress mites from stages of brood (newly sealed larvae, prepupae, white-eyed pupae, and pink-eyed pupae) and phoretic mites from adult bees. We then inoculated these mites into cells containing newly sealed larvae. Successful reproduction (foundress laid both a mature male and female) was low (13%) but most common in mites coming from sealed larvae. Unsuccessful reproductive attempts (foundress failed to produce both a mature male and female) were most common in mites from sealed larvae (22%) and prepupae (61%). Lack of any progeny was most common for mites from white-eyed (83%) and pink-eyed pupae (92%). We also collected foundress mites from sealed larvae and transferred them to cells containing newly sealed larvae, prepupae, white-eyed pupae, or pink-eyed pupae. Successful reproduction only occurred in the transfers to sealed larvae (26%). Unsuccessful reproductive attempts were most common in transfers to newly sealed larvae (40%) and to prepupae (25%). Unsuccessful attempts involved the production of immature progeny (60%), the production of only mature daughters (26%) or the production of only a mature male (14%). Generally, lack of progeny was not associated with mites having a lack of stored sperm. Our results suggest that mites exposed to the removal of prepupae or older brood due to hygiene are unlikely to produce viable mites if they invade new hosts soon after brood removal. Asynchrony between the reproductive status of reinvading mites and the developmental stage of their reinvasion hosts may be a primary cause of NR mites in hygienic colonies. Even if reinvading mites use hosts having the proper age for infestation, only a minority of them will reproduce.

Natural Varroa mite-surviving Apis mellifera honeybee populations

2015

-The Varroa destructor mite is the largest threat to apiculture worldwide and has been responsible for devastating losses of wild honeybee populations in Europe and North America. However, Varroa mite-resistant populations of A. mellifera honeybees have been reported and documented around the world with a variety of explanations for their long-term survival with uncontrolled mite infestation. This review synthesizes the work on naturally occurring survival to Varroa mites and discusses what these honeybee populations can signify for apiculture.Varroa destructor / mite resistance / host-parasite adaptations / natural selection / apiculture
