Abstract

Fenazaquin was found to be most toxic to all the three stages (egg, nymphal and egg stages) of O. coffeae. Hexythiazox was recorded to be much more toxic to egg stage as compared to nymphal and adult stage of O. coffeae. Dicofol was most toxic chemical on Amblyseius longispinosus and its LC-50 value was 0.0156.
