Absconding in honeybees (Apis mellifera) in relation to queen status and mode of worker reproduction

We investigated absconding frequency and latency in queenright and queenles s honeybee colonies in thelytokous Apis mellifera capensis, arrhenotokous A pis mellifera scutellata and their natural thelytokous hybrids. There was n o significant difference in frequency of absconding among any of the queenr ight colonies. Absconding was significantly greater in thelytokous queenles s colonies than in the queenless arrhenotokous ones. Latency to absconding did not differ among the three groups of queenright colonies nor between th e queenright and queenless colonies of A. m. capensis and A. m. scutellata. There were significant differences in latency between queenright and queen less hybrids and significant differences in latency among the three groups of queenless colonies. Among queenless colonies, A. m. capensis absconded t wice as readily as did A. m. scutellata and the hybrids were intermediate. Afterabsconding events include the fates of the absconding colony as well a s nestmates left behind. One group of orphaned nestmates of A. m. capensis amalgamated with another queenright colony. In the case of A. m. scutellata either drones were produced or the residual queenless colony was joined by a queenless thelytokous group, subsequently reared a queen and then abscon ded. Differences in the rate and degree of ovarial development indicate tha t queenless thelytokous workers have the physiological capacity for reprodu ction, a trait that contributes to colony fitness.
