A field trial on testing of Spirotetramat 12% + Imidacloprid 36% -480 SC and other newer molecules on survival of natural enemies of sucking pests in cotton crop was conducted at Agronomy Instructional Farm, C.P. College of Agriculture, S.D. Agricultural University, S.K. Nagar during Kharif, 2007–08 to 2008–09. based on two years results, it is revealed that Spirotetramat 12% + Imidacloprid 36% -480 SC @750 ml/ha, Spirotetramat 12% + Imidacloprid 36% -480 SC @ 625 ml/ha and Imidacloprid 200 SL@ 900 ml/ha were harboured more number of Chrysoperla at first, second and third spraying of insecticides, respectively. Spider population was recorded more in Thiomethoxam 25 WG@ 600 ml/ha, Spirotetramat 12% + Imidacloprid 36% -480 SC@ 625 ml/ha and Spirotetramat 12% + Imidacloprid 36% -480 SC@ 625 ml/ha at first, second and third spraying of insecticides, respectively. While ladybird beetle population were observed more in Spirotetramat 150 OD@ 600 ml/ha, Spirotetramat 12% + Imidacloprid 36% -480 SC @ 500 ml/ha and Spirotetramat 12% + Imidacloprid 36% 480 SC @ 625 ml/ha at first, second and third spraying for insecticides, respectively.
