Regulation of life history determines lifespan of worker honey bees (Apis mellifera L.).
Life expectancy of honey bees (Apis mellifera L.) is of general interest to gerontological research because its variability among different groups of bees is one of the most striking cases of natural plasticity of aging. Worker honey bees spend their first days of adult life working in the nest, then transition to foraging and die between 4 and 8 weeks of age. Foraging is believed to be primari...
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 کاملMorphometric Identification of Queens, Workers and Intermediates in In Vitro Reared Honey Bees (Apis mellifera)
In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days are grafted for queen rearing. Morphological classification (queen versus worker or intercastes) of bees produced by this method can be subjec...
متن کاملEffects of Pesticide Treatments on Nutrient Levels in Worker Honey Bees (Apis mellifera).
Honey bee colony loss continues to be an issue and no factor has been singled out as to the cause. In this study, we sought to determine whether two beekeeper-applied pesticide products, tau-fluvalinate and Fumagilin-B(®), and one agrochemical, chlorothalonil, impact the nutrient levels in honey bee workers in a natural colony environment. Treatments were performed in-hive and at three differen...
متن کاملThe ontogenetic pattern of mandibular gland components in queenless worker bees (Apis mellifera capensis Esch.).
The quantity and composition of the six major mandibular gland components of young queenless workers of the Cape honeybee (Apis mellifera capensis) were determined. The total amount of the six components increased with age. The relative quantities in the mandibular gland secretion of queenless caged workers were found to change rapidly during the first 4 days after emergence and to become domin...
