Direct and indirect effects of Juvenile Hormone Mimic (JHM), Pyriproxyfen 10% EC on the predatory mite, Phytoseius finitimus (Ribaga) (Acari: Phytoseiidae) were studied under the laboratory conditions. The side effects of pyriproxyfen on mortality, developmental duration periods, life-cycle, male and female longevity, oviposition period, female fecundity and egg viability were evaluated. Results clearly indicated that pypproxyfen exhibited no direct contact toxicity against mature and immature stages of the predatory mite, P. finitimus at all the tested concentrations (2.5 , 5 , 10 ppm). The highest concentration of 10 ppm showed low toxicity, causing 12.77 and 10.56 mortality% of protonymphs and adult females, respectively after 72 hours post treatment. In addition, pyriproxyfen exhibited no harmful indirect effects on developmental duration period, male and female longevity, female fecundity and egg viability at all the tested concentration. These results suggest that, pyriproxyfen could be a good alternative and interesting incorporation in /PM programs for controlling the two spotted spider mite, Tetranychus urticae due to its high toxicity on the target pest and has no harmful effects on it's predatory mite, P. finitimus, minimizing the usage of conventional chemical pesticides.
