Disease Resistance in Africanized Honey Bees
One of the consequences of the expansion is the health conditions of the bees in the countries where they are found today. It is known that the honey bees are susceptible to several diseases and bee pests such as EFB, AFB, Nosema, Amoeba, Sacbrood, Chalkbrood, Acarine, Varroosis, Viruses etc. The two most important diseases of honey bees are Varroosis and American Foulbrood (AFB) (DE JONG, 1994...
متن کاملRapid morphological changes in populations of hybrids between Africanized and European honey bees.
African honey bees, introduced to Brazil in 1956, rapidly dominated the previously introduced European subspecies. To better understand how hybridization between these different types of bees proceeded, we made geometric morphometric analyses of the wing venation patterns of specimens resulting from crosses made between Africanized honey bees (predominantly Apis mellifera scutellata) and I...
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 کاملRange and Frequency of Africanized Honey Bees in California (USA)
Africanized honey bees entered California in 1994 but few accounts of their northward expansion or their frequency relative to European honey bees have been published. We used mitochondrial markers and morphometric analyses to determine the prevalence of Africanized honeybees in San Diego County and their current northward progress in California west of the Sierra Nevada crest. The northernmost...
متن کاملColor-dependent learning in restrained Africanized honey bees.
Associative color learning has been demonstrated to be very poor using restrained European honey bees unless the antennae are amputated. Consequently, our understanding of proximate mechanisms in visual information processing is handicapped. Here we test learning performance of Africanized honey bees under restrained conditions with visual and olfactory stimulation using the proboscis extension...
