Pesticides are frequently applied against sucking insects in Turkey and these pesticides cause an effect on predator mites, which are important natural enemies of Panonychus citri (McGregor) (Acari: Tetranychidae). Among the predatory mites, Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is an important species that feeds not only on P. citri but also on pests such as thrips and whiteflies. In this study, the effects of afidopyropen, spirotetramat, and sulfoxaflor, which are authorized in citrus in Turkey, on A. swirskii larvae were determined. Dimethoate was used as a toxic pesticide. As a result of the applications, the effects on larvae were found to be 31.67 %, 78.23 %, and 28.96 % for afidopyropen, spirotetramat, and sulfoxaflor, respectively. While the number of daily eggs per female was 3.73 in control, it was detected as 2.63, 0.80, and 1.36 for insecticides, respectively. The rate of decrease in egg production was found as 29.51 %, 85.30 %, and 56.69 %,
respectively. According to these results, afidopyropen and spirotetramat were moderately harmful (M), and sulfoxaflor was determined as harmless (N).
