Male fitness of honeybee colonies (Apis mellifera L.).
Honeybees (Apis mellifera L.) have an extreme polyandrous mating system. Worker offspring of 19 naturally mated queens was genotyped with DNA microsatellites, to estimate male reproductive success of 16 drone producing colonies. This allowed for estimating the male mating success on both the colony level and the level of individual drones. The experiment was conducted in a closed population on ...
متن کاملEffects of Oxalic Acid on Apis mellifera (Hymenoptera: Apidae)
Abstract: Oxalic acid dihydrate is used to treat varroosis of Apis mellifera. This study investigates lethal and sublethal effects of oxalic acid dihydrate on individually treated honeybees kept in cages under laboratory conditions as well as the distribution in the colony. After oral application, bee mortality occurred at relatively low concentrations (No Observed Adverse Effect Level (NOAEL) ...
متن کاملThermal learning in the honeybee, Apis mellifera.
Honeybee foragers are exposed to thermal stimuli when collecting food outside and receiving food rewards inside the nest. In both contexts, there is an opportunity for foragers to associate warmth with food rewards. However, honeybee thermal learning is poorly understood. Using an associative learning paradigm (the proboscis extension reflex), we show that honeybees can learn to associate a nec...
متن کاملThe role of the vibration signal during queen competition in colonies of the honeybee, Apis mellifera
Temporary polygyny (the presence of multiple queens) occurs in honeybee colonies when virgin queens (VQs) are reared for reproductive swarming or queen replacement. During these events, workers perform vibration signals on queen cells and emerged queens, and these signals may influence which VQ becomes the new laying queen of a colony. We examined the role of vibration signals during queen comp...
متن کاملResonance frequencies of honeybee (Apis mellifera) wings.
During flight, insect wings bend and twist under the influence of aerodynamic and inertial forces. We tested whether wing resonance of honeybees (Apis mellifera) matches the wingbeat frequency, against the 'stiff element' hypothesis that the wing's first longitudinal mode exceeds the wingbeat frequency. Six bees were immobilized with their right wing pair outspread, and stimulated with a shaker...
