Abstract: 
Injection of the insect growth regulator azadirachtin into 40-h-old last larval instars of Epilachna varivestis (Mulsant) inhibited metamorphosis at doses lower than 0.3 .mu.g. Various higher doses (0.3-1.0 .mu.g) caused in addition weight gain reduction, whereas weight gain was almost entirely suppressed after injection of 2.5 .mu.g. Histological and electrophoretical analyses showed that storage protein formation in the fat body, necessary for pupation, did not occur in higher dose treated (1.0 .mu.g) individuals, but it was not affected by low dose (0.1 .mu.g) treatment. It is assumed that azadirachtin causes metabolic defects at higher concentrations.
