Sublethal effects of spinosad on some biochemical and biological parameters of Glyphodes pyloalis Walker (Lepidoptera: Pyralidae)
Plant Protection Science 50 (3), 135-144
Abstract: The susceptibility of G. pyloalis larvae to spinosad was studied using the leaf dip method. Treatment with doses of spinosad sublethal concentrations (LC₁₀, LC₂₀, LC₃₀, LC₄₀ of 0.026, 0.045, 0.065, 0.090 ppm, respectively) was applied. A significant difference in the effects was observed between the sublethal concentrations (LC₁₀, LC₂₀, LC₃₀, and LC₄₀) and the control in the content of carbohydrate and glycogen, and between the control vs. LC₃₀ and LC₄₀ in the content of protein. A significant decrease in glutathione S-transferase activity with the increase of spinosad concentration, no significant differences in the activities of α- and β-esterases, and a significant increase in the enzyme activity of phenoloxidase were observed. Effects of LC₁₀ and LC₃₀ spinosad concentrations on some biological parameters showed that percentage of larval pupation and female fecundity significantly decreased in the concentration of LC₃₀.
