Adult females of E. orientalis showed high susceptibility to Polo and Neoron at all concentrations in comparison with the control and the concentration of 0.2 of Polo was the least efficient (p< 0.01). The effect of the concentration of 0.3 was lower than other Neoron concentrations. No significant differences in efficiency were observed between the concentration of 0.6; 0.7 of Polo and 0.75; 1; 1.25 of Neoron in this experiment.
