ipsilon development duration, normal food consumption and digestion process, enzymatic properties, hormone levels, fecundity and population levels. These results suggest that chlorantraniliprole at low concentrations can impair A. Importantly, these chlorantraniliprole-induced changes affected life table parameters of the cutworm. Compared with the control treatment, chlorantraniliprole significantly reduced digestive enzyme activities and observably increased detoxifying and protective enzyme activities and hormone titers. ipsilon larvae treated with low doses of chlorantraniliprole decreased food utilization and nutrient content (protein, lipid, carbohydrate, trehalose), showed lower pupal weights and growth rates. Furthermore, compared to those treated with the control, A. Relative to the control treatment, chlorantraniliprole decreased pupal and adult emergence rates, fecundity and fertility and increased the proportions of developmental deformities, the adult preoviposition period (APOP) and the total preoviposition period (TPOP). The development time of the larval, pupal and adult stages was significantly affected after chlorantraniliprole exposure, compared to the control treatment.
ipsilon, and the LC 50 was 0.187 μg.g −1 of artificial diet after treatment for 72 h. Chlorantraniliprole exhibited signs of active toxicity against third instar larvae of A.
A diet-incorporation-based bioassay was conducted to evaluate the sublethal effects of the novel anthranilic diamide chlorantraniliprole on the nutritional physiology, enzymatic properties and population parameters of this cutworm. Agrotis ipsilon (Lepidoptera: Noctuidae) is a major underground pest that damages many agricultural crops in China and other countries.
