Mortality of adults, eggs (and the crawlers hatching from them), small and large nymphs, and pupae were evaluated following insecticide treatments. All tests were conducted using two-leafed plants. To evaluate toxicity to adults, plants were sprayed with the insecticidal preparations. When the sprays had dried, leaves were excised and placed individually in water-filled vials in 34 oz screen-ventilated plastic containers. Twenty five adults were caged on each of 4 leaves for each treatment and mortality was evaluated after the containers had been held 2 d in a room at 27°C. To evaluate toxicity to the immature stages, plants were exposed 24 h to adults. Two 2-leaved plants with 25 eggs/leaf were sprayed for each treatment the same day that adults were removed. The numbers of crawlers that died as they exited the eggs or that died in close proximity to the eggs were recorded 1 wk later. The small amount of mortality that was observed in the egg stage was added to crawler mortality. Other plants were held until either small nymphs, large nymphs or pupae were present. Two 2-leaved plants with 25 individuals of the desired lifestage/leaf were sprayed for each treatment. When the individuals on the check had developed to the next lifestage, mortality of the treated lifestage was evaluated.
