A field investigation was carried out to assess the population fluctuation of bollworm complex and their natural enemies on non-Bt cotton. Twenty treatments including four botanicals were evaluated initially against sucking pests and continued further for check against bollworm complex with scheduling HaNPV, Bt and spinosad. The minimium egg and larval population of Helicoverpa armigera was reported in the application of NSE 5% and Azadirachtin 1500 ppm followed by spinosad 45 and HaNPV 250 LE/ha. However, the application of NSE 5% and Azadirachtin 1500 ppm followed by spinosad 45 SC was better in reducing larval population of Easias vitella. The treatment schedules comprising four botanicals followed by spinosad 45 SC as well as Bt 1000 g/ha have been found effective in reducing the larval population of pink bollworm in green bolls. The sole treatments of botanicals and the applications of botanicals followed by HaNPV 250 LE/ha have been observed to be safer to adults of coccinellids beetles, Chrysoperla zastrowi sillemi eggs and larvae as well as spiders.Keywords

A field experiment was conducted on the farm of Department of Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola to evaluate suitable cost effective combinations of microbial insecticides, plant product and reduced dose of insecticide in an integrated manner for management of Helicoverpa armigera (Hubner) on chickpea, Pooled data on per cent larval reduction after second spray revealed significant superiority of HaNPV alternated with endosulfan (0.07%) at fifteen days after spraying (92.61) and mixed spray of HaNPV with half the recommended dose of endosulfan (88.16), Higher grain yield of 18.47 q/ha and 17.97 q/ha, repectively was also recorded in the same treatments, found on par with each other. In case of pod damage, combination treatment of HaNPV with half the recommended dose of endosulfan recorded minimum pod damage (6.40%). However, HaNPV alternated with endosulfan (0.07%) recorded economic returns of 1:10.14, Thus there is a possibility of alternating HaNPV with chemical insecticides for the effective management of pod borer in chickpea.Keywords

Studies conducted on the effect of different prey insects on reproductive potential of Chrysoperla carnea (Stephens) revealed that there is no correlation between the fecundity and ovipositional period. The highest fecundity (467.2 eggs/female) was obtained on sterilised eggs of Corcyra cephlonica (Stainton) while the highest ovipositional period (51.75 days) was observed on neonates of Helicoverpa armigera (Hubner). Among prey insects tested, sterilised eggs of C. cephalonica have been found ideal for production of C. carnea.Keywords

An experiment conducted in the laboratory on the effect of host, Corcyra cephalonica on the development of Chrysoperla carnea (Stephens) revealed that the maximum eggs (53.29 per day) were consumed in the treatment of 125 eggs/day which also recorded minimum larval and pupal periods of 8.04 and 9.17 days, respectively. Whereas, the treatment 100 eggs/day noted maximum pupal weight (8.42 mg) and the highest fecundity (350.75 eggs/female) as well as the maximum adult longevity (46.50 days). The food offered as 25 eggs/day has shown the adverse effect on the development of predator.Keywords

An experiment was conducted in the laboratory on effect of Corcyra cephalonica (Stainton) density on six biological parameters of Chrysoperla carnea (Stephens). The result revealed that the maximum eggs (53.29 per day) were consumed in the density of 125 eggs/day, which also recorded minimum larval and pupal periods of 8.04 and 9.17 days, respectively. Whereas in the density of 100 eggs/day, maximum pupal weight (8.42 mg), highest fecundity (350.75 eggs/female) and maximum adult longevity (46.5 days) was observed.
