The present study aimed to minimize the pollution effects of traditional insecticides on the environment by development and synthesis of bio-insecticide and to evaluate insect growth regulators , Lufenuron as insecticidal agents. Stock colony of Schistocerca gregaria was used in this study which were kept in cages and fed on leaves of Castor plant. Treatment of the fifth nymphal instar of locusts by using insect growth regulator, Lufenuron were carried out.
Results showed that, the treatment with different concentrations of Lufenuron (50, 75 and 100 ppm) resulted in nymphal mortality of 0.0, 12.33 and 21.01% respectively and percentages of adult malformed with 89.99, 73.34 and 72.33 respectively comparing with control. The current study showed that Lufenuron caused malfunction and decomposition of the components in the muscles of the desert locust.
