Determination of Side Effects of Some Pesticides Predatory Mite Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae) in Laboratory Conditions

16239

In this study, which was carried out in the laboratories at Süleyman Demirel University, Faculty of Agriculture, Department of Plant Protection between 2010 and 2011, the side-effects of 6 pesticides on the predatory mite Phytoseiulus persimilis A.-H. (Acari: Phytoseiidae) were investigated by using spray tower- leaf disc methods. This study, indoxacarb was used as insecticide; and spiromesifen and abamectin were used as acaricie-insecticide and, hexythiazox, spirodiclofen and cyhexatin were applied as acaricide. Three doses of these pesticides were applied: field application dose (T), half field application dose (T/2) and double field application dose (2T). Dead-live counts were made 1, 3, 5 and 7 days after application. Additionally, the effect of pesticides on egg efficiency of predator mite was evaluated by daily counts of the eggs of adult females. Indoxacarb and hexythiazox was determined to have a moderately harmful at all doses. At 2T and T doses, abamectin, spiromesifen and spirodiclofen were found harmful and cyhexatin was found to be moderately harmful to Phytoseiulus persimilis. At T/2 dose, abamectin, spiromesifen and spirodiclofen were found moderately harmful and cyhexatin was found to be harmless. Significant differences in reproduction were found between the control group, 2T and T doses of indoxacarb and three doses of abamectin, cyhexatin and spirodiclofen in terms of egg prodution of female Phytoseiulus persimilis. No significant difference in egg efficiency was found between the control group and other groups exposed to pesticides.
