Popis: The present investigation was undertaken to find out the effective and economical control measures for the management of foliage feeding wheat aphids, for which three insecticides viz quinalphos 25 EC, thiamethoxam 25 % WG, and spinosad 45 EC were evaluated. Minimum aphid population was observed in case of quinalphos 25 EC @1600 ml/ha and was found at par with spinosad 45 EC @125 ml/ha and was found significantly better than other treatments, viz. quinalphos @1200 ml/ha and thiamethoxam 25 % WG @ 100 gm/ha including untreated check after 7 days of treatment. However, quinalphos 25 EC @1600 ml/ha and spinosad 45 EC @125 ml/ha and significantly better than other treatments including untreated check. Grain yield of plot treated with quinalphos 25 EC @1600 ml/ha was registered with highest yield (39.25 q/ha) and significantly better than other treatments including control. Cost-benefit ratio and net profit calculated for different insecticidal treatments revealed that quinalphos 25 EC @1600 ml/ha (1:9.65) was found highly cost effective as compare to other insecticides.
