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.

Army Worm

Mortality of eggs, first, third, and fifth instars and adults of fall army worm (FAW), Spodoptera frugiperda (J. E. Smith), after exposure to several insecticides on cotton indicated that the FAW is susceptible to most insecticides currently used to control Heliothis spp. Most insecticides tested exhibited ovicidal activity. High mortality of first instar larvae was observed for most treatments, including the biological insecticide, Bacillus thuringiensis (Berliner). More variation in mortality among treatments was observed in third and fifth instars than in first instars. Pyrethroid, carbamate, and organophosphorous insecticides resulted in higher mortality than did B. thuringiensis. Diflubenzuron, an insect growth regulator, was as effective as commonly used insecticides against third and fifth instar larvae when mortality was observed at pupation. Third instar FAW placed on plant tissue from the upper section of cotton plants sprayed in field situations suffered higher mortality than those placed on plant tissue from lower sections in the plant canopy. Inadequate deposition of insecticide in the lower portions of the cotton plant appears to be a limiting factor in control of FAW larvae on cotton.
