Leaves were placed in 1 oz plastic creamer cups with moist filter paper. Colony reared larvae were placed on the leaves and sprayed with a hand-held mist bottle for contact/residual efficacy resting. For residual efficacy, leaves were sprayed and air-dried before placement in cups with larvae. Mortality assessments were made at 1 and 14 DAT. Each treatment was replicated 4 times with 10 cups/replicate and 1 larva per cup.
