Side Effects of Four Acaricides on the Predatory Mites of Neoseiulus californicus McGregor and Phytoseiulus persimilis Athias‐Henriot (Acari: Phytoseiidae)

25552

In the present study determined the side effects of four acaricides ofacequinocyl, etoxazole, bifenazate and milbemectin on the predator mites Phytoseiuluspersimilis Athias‐Henriot and Neoseiulus californicus McGregor. Acaricideconcentrations were prepared as a two times the field application dose (2T), fieldapplication dose (T), and half of the field application dose (T/2) and were then appliedon eggs, nymphs and adults of the P. persimilis and N. californicus. The side effects of theacaricidesapplied to the predator mites were determined three, five and seven daysafterthe application. While all doses of acequinocyl and etoxazole showed a higher toxiceffect on N.californicus eggs, it was found that bifenazate and milbemectin causedsimilar effects on both predator mite eggs. Furthermore, it was found that the toxiceffects of acequinocyl, etoxazole, bifenazate and milbemectin on nymphs and adults ofthe predator miteswere high seventh day after the application. The results of the studyshowed that four acaracides frequently used against to pest mites, should be used more carefully in the agricultural areas.
