The present investigation entitled “Evaluation Economical Vaibility of Insecticides through Stem Smearing on Sucking Pests of Cotton In Relation To Yield” was conducted during kharif season of 2014-15 at Experimental farm of Department of Agril. Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, to evaluate the effects of stem smearing treatments on sucking pests (aphids, leafhoppers, thrips and whiteflies), natural enemies, yield and ICBR of cotton. Amongst the treatments tested, the treatments with imidacloprids 48 FS @ 1:5 recorded highest yield of seed cotton i.e. 134.13 kg/ha. Maximum reduction of population of leafhoppers and thrips was noticed in treatments of acephate 50 + imidacloprid 1.8 SP @ 1:5 and emerged as most effective recording higher net profit (1039.64 Rs./ha). The stem smearing with imidacloprid 48 FS @ 1:5 and acephate 50 + imidacloprid 1.8 SP @ 1:5 dilutions applied at 20 and 40 days after emergence proved better in recording higher avoidable losses i.e. 34.70 to 34.31 per cent.
