The investigation entitled"Biosafety evaluation of essential oils and chemical insecticides on population of coccinellids in rice field” was carried out at Research cum Instructional Farm of IGKV, Raipur (C.G.) during Kharif, 2017-18 and the field study was carried out to evaluate the safety of essential oils i.e., Camphor oil, Cedarwood oil, Eucalyptus oil, lemongrass oil, Neemazal and chemical insecticides i.e., Dinotefuran and Rynaxypyr to coccinellids (Ladybird beetles) in the rice fields brought out that all essential oils were found less toxic to coccinellids population and among them the safest one is Neemazal @ 2.0ml/l with highest coccinellids population i.e.,1.72 per hill. The Chemical insecticide i.e., Dinotefuran @ 0.50g/l was more fatal to Coccinellids with the lowest mean population i.e., 0.39 whereas maximum coccinellids population was found in the untreated control (1.98).
