Queen Replacement in Dequeened Colonies of the Argentine Ant Iridomyrmex Humilis
Replacement of killed or damaged queen by a new inseminated queen produced in the same nest is regularly accomplished in honey bees (Butler, 1967; Wilson, 1971; Michener, 1974). In the lower termites, e.g., Calotermes, it has been known for a long time that the removal of the sexual pair leads to the differentiation of neotenic reproductives from larval, pseudergate or nymphal forms (Grass6 and...
متن کاملModelling information exchange in worker-queen conflict over sex allocation.
We investigate the conflict between queen and worker over sex allocation, specifically the allocation of the queen's eggs between workers and reproductives and the allocation of the reproductive eggs between male and female. In contrast to previous models, we allow workers to observe and use information about the strategy of the queen. We consider three conflict models: simultaneous (no informa...
متن کاملSex ratio conflict and worker production in eusocial hymenoptera.
The best known of the conflicts occurring in eusocial Hymenoptera is queen-worker conflict over sex ratio. So far, sex ratio theory has mostly focused on optimal investment in the production of male versus female sexuals, neglecting the investment in workers. Increased investment in workers decreases immediate sexual productivity but increases expected future colony productivity. Thus, an impor...
متن کاملSex Determination, Sex Ratios and Genetic Conflict
Genetic mechanisms of sex determination are unexpectedly diverse and change rapidly during evolution. We review the role of genetic conflict as the driving force behind this diversity and turnover. Genetic conflict occurs when different components of a genetic system are subject to selection in opposite directions. Conflict may occur between genomes (including paternal-maternal and parentalzygo...
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 ...
