Worker reproduction and policing in insect societies: an ESS analysis.
Insect societies are vulnerable to exploitation by workers who reproduce selfishly rather than help to rear the queen's offspring. In most species, however, only a small proportion of the workers reproduce. Here, we develop an evolutionarily stable strategy (ESS) model to investigate factors that could explain these observed low levels of reproductive exploitation. Two key factors are identifie...
متن کاملEvolution of worker policing.
Workers in insect societies are sometimes observed to kill male eggs of other workers, a phenomenon known as worker policing. We perform a mathematical analysis of the evolutionary dynamics of policing. We investigate the selective forces behind policing for both dominant and recessive mutations for different numbers of matings of the queen. The traditional, relatedness-based argument suggests ...
متن کاملColony stage and not facultative policing explains pattern of worker reproduction in the Saxon wasp.
Inclusive fitness theory predicts that in colonies of social Hymenoptera headed by a multiple-mated queen, workers should benefit from policing eggs laid by other workers. Foster & Ratnieks provided evidence that in the vespine wasp Dolichovespula saxonica, workers police other workers' eggs only in colonies headed by a multiple-mated queen, but not in those headed by a single-mated one. This c...
متن کاملHormonal control of tick development and reproduction.
Ecdysteroids (moulting hormones), juvenoids and neuropeptides in ticks are reviewed but, by far, the emphasis is on the former since this class of hormones has been the subject of most investigations. In immature stages of ticks, ecdysteroids have been shown to regulate moulting and to terminate larval diapause. Although there is a paucity of information on the molecular action of ecdysteroids ...
متن کاملConflict over sex ratio and male production in paper wasps
Kin selection theory has been used to generate several useful frameworks in the field of evolutionary ecology. We briefly review the research on two main theoretical predictions for sex ratio variation among colonies, and for worker policing, using a relatedness framework in paper wasps. Contrary to the studies of advanced eusocial wasps, conclusive evidence showing worker control of sex ratio ...
