METHOD: Feeding Behavior CONDITIONS: Field and Lab - 16h light at 20-26C and 60-90% RH METHOD NARR: The effect of larval body size on acquisition of trichome exudate was examined. This was done both in the lab using detatched lld. The effect of environment on trichome density was also examined. RESULTS NARR: The # of tarsi bearing exudate increased significantly as successive larval instars were confined for 24h on ber 310927. This accession atarsal encasement than the others tested. Both 1st & 3rd instars collected far less exudate in field plots of ber than in lab tests. The environment did not significantly influence type A trichome density, while for type B itaxial surface. AUTHOR EXPLANATION: The tendency of young CPB larvae to feed on the underside of leaves may explain the lower incidence of exudate accumulation on sone accessions. Large larvae acquire exudate more rapidly than do sm indument of trichomes may simply deter or physically prevent larvae from setting into a suitable feeding site, and spending more time on grooming or searching activities.
