Effect of three insect growth regulators on certain biological aspects of the lesser grain borer, Rhyzopertha dominica (Coleoptera: Bostrichidae).

The current study was performed to evaluate the efficacy of certain insect growth regulators (IGRs), buprofezin, hexaflumuron, and lufenuron, at different concentrations (0.2, 0.4, and 0.8 ppm) against Rhyzopertha dominica in wheat grains. Our data showed that the three IGRs tested at different concentrations significantly affected the mortality of adults to varying extents. The percentage mortality of adults increased with increasing concentrations and time of exposure. After 21 days of treatment, the highest mortality (80.00%, 78.33%, and 60.00%) was observed at the highest concentration (0.8 ppm) and the lowest mortality (58.33%, 46.66%, and 30.00%) was observed at the lowest concentration (0.2 ppm) of lufenuron, buprofezin, and hexaflumuron, respectively. The tested IGRs reduced fecundity, hatchability, adult emergence, and weight loss in treated wheat grains and increased the developmental period of R. dominica compared with the control.
