The study was conducted to evaluate the direct spraying effects of Triflumuron and Diflubenzuron at 250, 500, 1000 and 2000 ppm on the mortality of alates and workers of termite Microcerotermes diversus ( Silv.) at 30 ± 3ºC and 85 ± 5% R.H. The results showed that all concentrations of Triflumuron and Diflubenzuron have caused slow and gradual mortality to termite individuals. Hundred percent mortality in termite workers was achieved with all concentrations of both Triflumuron and Diflubenzuron after three weeks of application, except that for the concentration 250 ppm of Diflubenzuron, where the achievement of 100% mortality was taken 2 weeks only. It was found that early mortality in the first week was connected with the concentration so increasing Triflumuron concentration induced increasing in mortality, while increasing Diflubenzuron induced decreasing in mortality. All concentrations of Triflumuron and Diflubenzuron caused deformations in workers, abdomen swellen, abnormal shape, discolored to white lackluster associated with slow movement. High mortality of termite alates have exhibited by the two CSIs reached to 100% after two weeks of application. The termite alates were found to be more sensitive to Triflumuron and Diflubenzuron than workers. All concentration of the two CSIs caused failure eggs hatch laid by termite alates.
