The expression profile of MmedOR49 in the antennae of female M. mediator. (A) Location of MmedOR49 in the antennae of female M. mediator. The biotin-labeled antisense RNA probe for MmedOR49 was labeled in the olfactory sensory neurons (OSNs) of the antennal flagella of the females. (B) Amplification of the labeled OSNs. (C)MmedOR49 expressions in female antennae at different developmental stages and physiological states. (a) Red-eyed pupae, (b) half-pigmented pupae, (c) fully pigmented pupae, (d) newly emerged adult, (e) unmated adult, (f) mated adult without parasitism experience, (g) mated adult with parasitism experience. The significant differences of transcription levels among samples are indicated by different lowercase letters (P < 0.05).
