The Effects of Sub lethal doses of Epiel . Abamectin and Imidacloprid on the Biological Parameters of Trialeurodes vaporariorum (Hem.:Aleyrodidae) in laboratory condition

Abstract

Abstract

The whitefly greenhouse (Trialeurodes vaporariorum) is one of the major pests of vegetable and ornamental crops in greenhouses throughout the world. In this research the effects of the new pesticide Epiel along with two pesticides Abamectin and Imidacloprid on the whitefly greenhouse were investigated. . In this study, the sub-lethal effects of these pesticides on some biological parameters of whiteflies greenhouse were studied. Based on the bioassay results, LC30 is considered a lethal concentration. The LC30 levels for the insecticides Epiel, Abamectin and Imidcloprid were 1.31, 0.00448 and 0.00868 mg / L. Life table parameters using were calculated from the equations provided by Carey(1993). Intrinsic population growth rates (rm) for control and pesticides for the insecticides Epile, Abacmetin and Imidacloprid were 0.123203, 0.121019, 0.121564 and 0.121734 of female progeny per day. Furthermore, the Net reproduction rate (R0) was 89.08, 51.36, 74.4 and 62.91 individuals. The results showed that the three formulated compounds harm some population parameters and biological characteristics of whitefly greenhouse and can be used in the integrated control program of whitefly greenhouse.
