Mate number, kin selection and social conflicts in stingless bees and honeybees

摘要: Microsatellite genotyping of workers from 13 species (ten genera) stingless bees shows that genetic relatedness is very high. Workers are usually daughters a single, singly mated queen. This observation, coupled with the multiple mating honeybee queens, permits kin selection theory to account for many differences in social biology two taxa. First, contrast honeybees, where predicted and do police each other's male production, bee compete directly queen rights produce males. leads behavioural reproductive conflict during oviposition. Second, risk daughter will attack mother higher as cost such an workers. explains why commonly have virgin queens nest, but honeybees not. It also leaves found new while it who leaves.
