Abstract
The ability of queens of the paper wasp Polistes fuscatus to recognize larv ae on the basis of colony origin was investigated in the laboratory. In a b lind, binary choice paradigm, queens discriminated between larvae from thei r own colony and unrelated larvae, and between larvae from a sister colony and unrelated larvae. However, queens failed to discriminate between larvae from their own colony and larvae from a sister colony, indicating that que ens of multiple-foundress colonies may lack the ability to make intracoloni al brood discriminations on the basis of relatedness. These results demonst rate that recognition of larvae is mediated by larval-borne, genetically sp ecified odors. Gas chromatograph/mass spectral analysis revealed that adult s and larvae have similar cuticular hydrocarbon profiles, suggesting that t he cues mediating larval and adult recognition may be the same.
