    The influence of pesticides on the viability and infectivity of EPNs S. feltiae, S. arenarium and S. kraussei was determined in water solutions of 13 pesticides. The most toxic pesticides were those containing oxamyl and sulphur. Trifluralin has a high potential for decreasing viability and it seems that chlorpyrifos, lambda-cyhalotrin, captan and mancozeb can also cause higher mortality. The difference between the tested species was not significant except for S. feltiae, which was more sensitive to pesticides than the others. It was found that both the exposure time and concentration of pesticides had a significant influence on the degree to which they impacted viability. The highest negative influence on infectivity was seen in oxamyl, sulphur and also mancozeb and fenitrothion. The exposure time had no significant influence on infectivity. Species S. arenarium had the lowest infectivity with S. feltiae having the highest. The concentration had a significant influence on infectivity.
