African 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 کاملHoney bees preferentially consume freshly-stored pollen
Honey bees (Apis mellifera) collect and store both honey and pollen in preserved forms. Pollen storage involves the addition of honey or nectar and oral secretions to pollen granules. It is controversial whether the duration of pollen storage alters the palatability or nutritive value of the pollen storage medium. We examined how bees utilize different-aged stored pollen during an extended poll...
متن کاملPollen Foraging Response to Brood Pheromone by Africanized and European Honey Bees (Apis mellifera L.)
We examined the pollen foraging responses of Africanized and European honey bee colonies to hexane extractable compounds of Africanized and European larvae (brood pheromone). Brood pheromone was presented to broodless Africanized and European colonies equalized for numbers of bees, food stores and, empty comb space. The pheromone signiÞcantly increased the ratio of pollen to nonpollen foragers ...
متن کاملSucrose responsiveness and behaviour in honey bees (Apis mellifera L.)
In dieser Arbeit wird bei der Honigbiene (Apis mellifera L.) analysiert, wie sich die individuelle Empfindlichkeit für Zuckerwasserreize auf verschiedene Formen der Verhaltensplastizität auswirkt. Die Versuche klären insbesondere die Rolle des Belohnungsreizes Zuckerwasser beim assoziativen und nicht-assoziativen Lernen auf. In den Untersuchungen werden Bienen verschiedenen Genotyps, verschiede...
متن کاملImmune pathways and defence mechanisms in honey bees Apis mellifera
Social insects are able to mount both group-level and individual defences against pathogens. Here we focus on individual defences, by presenting a genome-wide analysis of immunity in a social insect, the honey bee Apis mellifera. We present honey bee models for each of four signalling pathways associated with immunity, identifying plausible orthologues for nearly all predicted pathway members. ...
