Larval epicuticular substances are sufficient for recognition of nestmate larvae by adults and demonstrate that wasps are able to discriminate between alien and nestmate larval odours. Expand

Abstract.Identifying the sex of larvae is important in social Hymenoptera. Until now for Polistes wasps it has been necessary to genotype larvae at microsatellite loci, and assign their sex based on… Expand

The results demonstrate that parasite larvae have evolved a host larval profile, which overcomes the host colony recognition system probably because of the lower proportion of branched compounds compared to host larvae. Expand
Polistes dominulus (Hymenoptera, Vespidae) larvae show different cuticular patterns according to their sex: workers seem not use this chemical information.
Investigating the paper wasp Polistes dominulus to see if male and female larvae show different patterns of cuticular hydrocarbon mixtures and if workers are able to discriminate between male andFemale larvae on this basis found sex-based variation in CHC-profiles sufficient for discrimination.
