Analysis of odorant-binding protein gene family members in the polyembryonic wasp, Copidosoma floridanum: Evidence for caste bias and host interaction

- Primary structures of 8 odorant-binding protein (OBP) family members are analyzed.
- Phylogenetic relationships are inferred for the OBPs.
- DIG in situ and RT-PCR expression data is presented from different developmental stages and castes.
- Novel expression patterns are observed including the potential for export to host hemolymph.
- Potential roles of the OBPs in this study are discussed.
