Effect of thiacloprid (TIA) on electroantennogram (EAG) responses of males of C. pomonella, G. molesta and L. botrana to sex pheromone stimulation. Males treated with acetone or 4 lethal concentrations of TIA (LC0.001 to LC20) were stimulated with n-hexane and 3 concentrations (1 ng to 1 µg) of the major pheromone components of C. pomonella (E,E-8,10-12:OH), G. molesta (Z8-12:Ac) and L. botrana (E,Z-7,9-12:Ac). Three EAG parameters were measured: maximum response, and the duration of the downward and upward phases. The only significant TIA effect was a reduction of maximum response with LC1 in L. botrana. For each pheromone dose, different letters indicate significant differences among TIA doses, Tukey’s test after ANOVA (P < 0.05).
