| The findings showed that for the black cutworm A. ipsilon larvae exposed to various concentrations of Bio-Bower and lufenuron, the LC50 values obtained were 1.0677 and 0.0921 ppm, respectively. The results showed that, as compared to control, the duration of the larvae increased by 4.76% and 20.67% for Bio-power and lufenuron, respectively. Pupation rates decreased by 49.5% and 47.5%, respectively, for Bio-power and lufenuron, when compared to controls. Additionally, pupal duration was shorter for each of Bio-power and lufenuron when compared to controls, by 23.9 % and 22.2 %, respectively. When compared to the enzymatic activity in control insects, the enzyme activities for Bio-power and lufenuron show an increase in protease by 82.450 and 77.993% and a decrease in chitinase by 116.702 and 86.801%, respectively. These enzymes are a variety of hydrolases that are crucial for the physiological operation of the targeted insect and, as a result, for its metabolic pathway.The total level of protein decreased by 32.413% and 13.702%, lipid by 12.795% and 12.934%, and carbohydrate by 23.872% and 38.846%, according to the results of both treatments. | ||||
