Second-instar larvae were reared on artificial diet in a laboratory colony, 9 generations removed from field-collected moths. The test larvae were treated either by Hamilton syringe (topical application of 1 u,l to the dorsa' thorax) or by spray atomizer (contact mist) and then incubated for 48 h under 12:12 (L:D) photoperiod and 75-85°F within individual 1-oz creamer cup>; containing fresh artificial diet. For each application method there were 3 replicate sets/treatment level; 10 larvae/set. Mortality data were transformed h, arcsin p prior to 1-way analysis of variance.
