Abstract

The response of the parasitoidEucelatoria bryani Sabrosky to fresh plant material and several plant extracts was examined in an olfactometer. The plants tested can serve as a food source for hosts (Heliothis spp.) of the parasitoid. Females responded positively to 13 of the 19 fresh plant tissues tested, and all of the extracts tested. Males responded to only two of the fresh plant tissues and to none of the extracts. The significance of plant variety, morphology, and phenology on the host habitat-selection behavior of this parasitoid is discussed.
