Abstract: Imidazole compound KK-42 was tested for its inhibitory effect on Schisfocerca gregaria. The compound caused 80% mortality after 19 days of treatment with 100 µg of KK-42/insect. It also caused the production of deformed adults at even lower doses. Ecdysteroid content, when estimated by RIA, declined due to KK-42 treatment in both haemolymph and ovaries of the insect. Reduction in ecdysteroid titer was maximum at 100 µg of KK-42/insect. The value estimated by RIA was 0.34 ng/µL haemolymph as compared to 0.97 ng/µL in case of controls. Similarly, ecdysteroid content of ovaries detected was 0.48 ng/mg in treated ones as compared to 0.61 ng/mg in control s. Histological studies, however, revealed no alteration in the ovarian tissues due to KK-42 treatment.
