abstract
The experiment was conducted at two locations viz. farmer’s field and research farm during Kharif 2017 in Waraseoni, Balaghat (M.P.). Research farm was characterized by rigorous cultivation with frequent use of chemical insecticides and fertilizers while farmer’s field with conventional cultivation practice and least use of chemical inputs. Assessment of light trap collections in both the locations of paddy ecosystem indicated that in terms of total trap catch, pest species namely Melanitis ismene (34:66), Sogatella furcifera (35:65), and Nilaparvata lugens (36:64) were distinctly higher at farmer’s field, while 8 species were observed with no distinct difference at both locations. Comparison of predatory species in paddy ecosystem indicated that trap catches were distinctly higher in 6 species while higher in 7 species at farmer’s field. Overall comparison of predator v/s pest species through trap catch revealed that it was 1:7.43 at research field while 1:5.11 at farmer’s field.
