Comparative Efficacy of Insecticides Against Bemacia Tabaci and Thrips Tabaci on Cotton Crop

Abstract

Cotton is known as ‘‘The King of Fibers’’ and the natural fiber of the world. This 
current research was carried out to check the toxicity of endosulfan and imidacloprid against 
sucking insects like thrips and whitefly. The research was performed in district Sheikhupura in 
2023. For thrips and white fly, the data were recorded before 24 hours of spray, and then data were 
collected at 24, 48 and 72 hours and after that with a two-week duration until October. 25 plants 
were selected and from every plant 1 leaf from lower, middle and upper leaves were chosen, at 
different heights. In August spraying was performed when the economic threshold level (ETL) 
was reached. Results exhibited that the best toxicity was recorded in imidacloprid compared to 
endosulfan against whitefly and thrip population control. Hence, it was concluded that whitefly 
and thrips caused a huge amount of crop loss in cotton so, managed it timely by spraying the 
insecticides with suitable time intervals for better yield of cotton.
