ABSTRACT The effect of acetone and water extracts of Acacia auriculiformis A. Cunn. bark was investigated on biology of Bactrocera cucurbitae (Coquillett). The eggs, larvae and adults were treated with different concentrations (1, 5, 25, 125 and 625 ppm) of the bark extracts. Both the extracts significantly prolonged the larval period and total developmental period. Percentage pupation, percentage emergence, oviposition and egg hatching decreased in a dose dependent manner. The LC50 values were lower for the acetone extract as compared to water extract indicating that acetone extract was more toxic than water extract. The present findings demonstrated the potential of the plant extracts in controlling melon fruit fly.
