Sublethal effects of spinosad on some biochemical parameters of Xanthogaleruca luteola (Müller) (Coleoptera: Chrysomelidae)
Plant Protection Science 50 (4), 199-206
Abstract: The effect of spinosad on some biochemical characteristics of Xanthogaleruca luteola was investigated. LC₃₀ and LC₅₀ of spinosad for the third instar larvae were determined as 1.6 and 2.9 ppm, respectively. Biochemical tests were carried out on the 3^rd instar larvae treated with LC₃₀ and LC₅₀ of spinosad. The LC₃₀ concentration decreased carbohydrate and glycogen content and increased lipid content significantly. There was a significant decrease in carbohydrate, glycogen, and protein contents following the exposure to LC₅₀ concentration. Available energy of the larvae exposed to LC₃₀ of spinosad increased significantly, whereas it decreased significantly at LC₅₀. However, the energy consumed was increased at both concentrations significantly. Cellular energy allocation of larvae treated with LC₅₀ concentrations of spinosad decreased significantly. Glutathione-S-transferase and esterase activities were increased significantly at LC₅₀. However, lipase activity was decreased at both concentrations.
