Abstract :

Greenhouse whitefly (Trialeurodes vaporarium) Westwood is one of the most important plant pests in Iran and the world. Due to the resistance of whiteflies to common insecticides and the harmful nature of these insecticides to the environment, new and safe compounds should be sought to combat this pest. Epile's new insecticide with a new combination while controlling this pest is also less dangerous for the environment Based on the Bioassay results, LC30 is considered a lethal concentration. The LC30 levels for the insecticides Epile, Abamecetin and Omidochloroprid were 1.31, 0.00448 and 0.00868 mg/lit. The results showed that the application of sub-lethal concentration of the treatments by spraying reduces the length of egg hatching period for the insecticides of Epile, Abacmetin and Omidchloroprid by 11.33, 5.45 and 4.53%, respectively, compared to the control and Epile is less than the length of the egg-related insecticide period. Also, Epile insecticide increased the length of  the larva period by 5.13% and the pupa period by 0.62% compared to the control. Also, the lifespan of adult insects was reduced by 38.64%, and in general, it reduces the lifespan of whitefly.
