Laboratory Assay

A laboratory assay of the klinokinetic response of Trichogramma spp. to scales of Heliothis virescens (F.) and Heliothis zea (Boddie) was investigated. The assay indicated significant behavioral response to materials similar in size to lepidopteran scales (small glass beads, cotton fibers); however, response to these materials was significantly less than response to H. virescens scales. The assay did not distinguish any difference in response to H. zea scales betewen naturally occurring and laboratory-bred Trichogramma exiguum Pinto and Platner. Physiological status (freshly emerged, virgin vs. 3–4 day-old, mated) of the H. zea moths from which scales originated affected scale response, but anatomical origin (abdominal tip vs. abdominal venter vs. wing) of host scales did not.
