Effect of genotype, weight of honeybee virgin queens and brood status on some parameters used for judging the queens from their introduction until egg-laying. [electronic resource].

Includes reference.

Four Parameters were chosen in this study on which the effect of both weight and genotypes of honeybee queens as well as brood status were studied. One of these parameters is related to the premating period, being the acceptance rate of the introduced queens, and the others are related to post-mating period, being mating success, pre-oviposition period and sperm counts. The genotype of the queens had a significant effect on both pre-oviposition and the number of spermatozoa in the spermatheca, whereas this effect was not significant on acceptance rate and mating success. On the other hand, the weight of the queens showed a significant effect on both acceptance and pre-oviposition period, but did not show a significant effect on mating success and sperm count. A trend response was established to test the linear dependence of both acceptance rate and pre-oviposition period on the weight, and the result verified this relationship, being positive with the former and negative with the latter. The comparison between different genotypes under study showed the superiority of the F I-Italian hybrid queens to the remaining genotypes.
