Abstract

In this study, which was carried out in the laboratories at Ege University, Faculty of Agriculture, Department of Plant Protection between 2004 and 2005, the effects of 6 fungicides, 5 insecticides and 6 acaricides on the predatory mite Phytoseiulus persimilis A.-H. (Acarina: Phytoseiidae) were investigated by using residual film, direct spraying and slide dip methods. Chlorothalonil, metalaxyl+mancozeb, mancozeb, fomaxadone+ cymoxanil, cyprodynyl+ fludioxonil and trifloxystrobin were used as fungicide; acetamiprid, imidacloprid, pymetrozine, chlorpyrifos-ethyl and thiamethoxam were used as insecticide; and pesticides with such active ingredients as micronised sulphur, abamectin, hexythiazox, tebufenprayd, tetradifon, fenpyroximate were applied as acaricide.

Among the fungicides tested chlorothalonil, trifloxystrobin and cyprodynyl+ fludioxonil active ingredients were found to be non-toxic to the predatory mite in all three methods. Fomaxadone+cymoxanil should be tested in greenhouse conditions before being used. Metalaxyl+mancozeb and mancozeb were found to be toxic on P. persimilis
