Prabhakaran, Shripat T. Kamble] Technical grade azadirachtin (11.46% [AI]) was tested for its toxicity to insecticide-resistant and -susceptible strains of German cockroach, Blattella germanica (L.), by injection and diet incorporation. The effect of azadirachtin was dose dependent. The LC50 and LC90 for 3 strains ranged between 2.49 and 2.56 μg per insect and 6.49 and 6.92 μg per insect, respectively. Incorporation of Azadirachtin in food pellets resulted in LT50s of 22, 23, and 22 d for Dursban-R, CSMA, and Baygon-R strains, respectively. No significant differences were observed in toxicity of Azadirachtin to either insecticide-resistant or susceptible strains. The body weight of German cockroaches varied with time depending upon the dose administered. The roaches injected with 2 and 3 μg of Azadirachtin showed a continuous weight reduction. The toxicity of Azadirachtin to German cockroaches may be associated with an altered feeding behavior and a disruption of endocrinal events. © 1996 Entomological Society of America Physiological and Chemical Ecology nationallicence Blattella germanica nationallicence Azadirachtin nationallicence neem nationallicence resistance nationallicence bioassay nationallicence weight gain nationallicence Prabhakaran Suresh K.
