Jewett, D.K. | Carpenter, J.E.
Data supporting chemically-mediated communication between males and females of a pupal parasitoid Ichneumon (= Pterocormus) promissorius (Erichson) (Hymenoptera: Ichneumonidae) were gathered with a behavioral bioassay and electroantennography. Live I. promissorius females and a whole-body extract of females elicited greater responses from male antennae than did live males, a whole-body extract of them or a control. In behavioral bioassays, more I. promissorius males were recovered from traps baited with live females or the diethyl ether rinse of a glass substrate to which females were exposed than with live males, the diethyl ether rinse of a glass substrate to which males were exposed or a control. Volatile materials collected from live females either effluvially or by their immersion in solvent did not attract males.
