Symposium 7: The consequences of polyandry for colony organization
The adaptive significance of multiple mating of social insect queens remains an evolutionary puzzle. Although the evolution of polyandry is controversial, the proximate consequences of a high genotypic intracolonial diversity have been studied in a series of insect societies. The symposium comprises various examples in which multiple mating has very different consequences, ranging from the fine tuning of task specialization among workers to the compete failure of colony reproduction.
