Queen developmental time and fitness consequences for queens of clonal social parasitic honeybees (A. m. capensis) and its host A. m. scutellata
2005
The social parasitic honeybees of South Africa (Apis mellifera capensis) consist of a single clonal lineage, which has been selected for traits related to worker reproduction. Viable queens of this parasitic clonal lineage have never been observed. We tested if it is possible to rear queens from eggs of the social parasitic workers. In a competitive situation, using larvae of the parasitic clonal lineage and of the host, we tested the discriminatory ability of host colonies (A. m. scutellata) between parasitic and non-parasitic larvae. We found evidence for a reduced fitness of queens reared from the social parasite lineage, resulting from a longer developmental time. The results are discussed in the light of a fitness trade-off between queen and worker caste.
