Parasitoids employ different suites of host-related volatiles for foraging and host location. In order to test the hypothesis of differential response of parasitoids to different host-related volatiles, we compared the electroantennogram (EAG) responses of both sexes of the specialist parasitoid, Microplitis croceipes (Cresson) and the generalist, Cotesia marginiventris (Cresson) to varying doses of select host-plant volatiles: two green leaf volatiles (GLVs) (cis-3-hexenol and hexanal), and three inducible compounds (cis-3-hexenyl acetate, linalool, and (E,E)-a-farnesene). The data showed a significant effect of sex on EAG responses of both parasitoids; however mating had no significant effect on EAG response. Females of both species showed significantly greater EAG response than conspecific males to the two tested GLVs (cis-3-hexenol and hexanal), while the three tested inducible compounds (cis-3-hexenyl acetate, linalool, and (E,E)-a-farnesene) elicited significantly greater EAG in males than in conspecific females at high doses, supporting the hypothesis that female parasitoids are more responsive than conspecific males to GLVs released immediately after initiation of herbivore feeding damage, whereas males show greater response than conspecific females to inducible compounds released much later after initial damage. In general, C. marginiventris females and males showed greater EAG response than counterpart M. croceipes to the tested compounds at various doses, possibly suggesting that the generalist parasitoid is more responsive than the specialist to the tested host-plant volatiles.
