Inheritance of traits associated with reproductive potential in Apis mellifera capensis and Apis mellifera scutellata workers.
When workers of the thelytokous Cape honeybee, Apis mellifera capensis, come into contact with colonies of the neighboring arrhenotokous subspecies Apis mellifera scutellata, they can become lethal social parasites. We examined the inheritance of 3 traits (number of ovarioles, number of basitarsal hairs, and size of spermatheca) that are thought to be associated with reproductive potential in A...
متن کاملDevelopment of Varroa jacobsoni in colonies of Apis mellifera capensis and Apis mellifera carnica
Honey bee colonies (Apis mellifera carnical, infested with Varroa jacobsonl were de-queened and divided into 2 subunits. Each pair of subunits were requeened with an inseminated A m capensis and A m carnica queen. The development of the mite population was monitored by determining the number of mites in samples of brood, and worker bees, and lhe number of dead mites on the bottom board of the h...
متن کاملAfrican Honey Bees (apis Mellifera Scutellata) and Nosema (nosema Apis) Infections
Nosema apis has been found on all continents where there is beekeeping using Apis mellifera. However, there is very little data on the prevalence and impact of Nosema apis in honey bee colonies in tropical climates and it may be uncertain if all records of Microsporidia in honey bees actually are records of the same parasite. Also, the development of N. apis has not been documented in tropical ...
متن کاملAsexually produced Cape honeybee queens (Apis mellifera capensis) reproduce sexually.
Unmated workers of the Cape honeybee Apis mellifera capensis can produce female offspring including daughter queens. As worker-laid queens are produced asexually, we wondered whether these asexually produced individuals reproduce asexually or sexually. We sampled 11 colonies headed by queens known to be the clonal offspring of workers and genotyped 23 worker offspring from each queen at 5 micro...
متن کاملIndividual Variability of Nosema ceranae Infections in Apis mellifera Colonies
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N. ceranae is a fairly recently discovered parasite, there is little knowledge of the variation in infection levels among individual workers within a colony. In this study we examined the levels of infec...
