Richa Choudhary, Gajendra Chandrakar, Jyoti Raama Bhardwaj and Hadi Husain Khan

The investigation entitled “Effects of Neem based Insecticides on Coccinellids and Staphylinids Population in Rice Field” was carried out at Research cum Instructional Farm of IGKV, Raipur (C.G.) during Kharif, 2015-16 and The Field study carried out to evaluate the safety of neem based compounds i.e., Neembaan Neemazal, Nimbecidine, Multineem, Neem oil, NSKE and chemical pesticide i.e., Dinotefuran to Coccinellids (Lady bird beetles) and Staphylinids (Rove beetles) in the rice fields brought out that all six Neem based insecticides were found less toxic to Coccinellids population and among them the safest one is Nimbecidine @ 5ml/l with highest Coccinellid population i.e., 2.32 per hill. The Chemical insecticide i.e., Dinotefuran @ 0.5g/l was more fatal to Coccinellids with lowest mean population i.e., 0.30 whereas maximum Coccinellid population was found in untreated control (2.50). Similarly for rove beetles all Neem based insecticides were found safer than chemical insecticide. Lowest population was recorded from plot treated with Dinotefuran @ 0.5g/l (0.28) and highest population was recorded from untreated control plot (1.86). Among the botanicals lowest population was recorded from plot treated with Neem oil @ 5ml/l which is 1.60.
