A field experiment management of sucking pests by using newer insecticides and their effect on natural enemies in tomato (Lycopersicon esculentum mill.) was conducted at Mahatma Phule Krishi Vidyapeeth, Rahuri during the year 2013-2014.Eight insecticides used against the sucking pests viz., aphid, whiteflies and thrips. The result of this study revealed that the spinosad 45 SC @ 125 g a.i/ha emerged as most effective treatment to reduce the aphid (2.09-3.07), whitefly (1.51-2.27), thrips (0.71-1.64) per three leaves/plant and it gave highest marketable yield of tomato (45.47 t/ha) it was followed by cypermethrin 25 EC @ 62.50 g a.i./ha, abamectin 1.9 EC @ 3 g a.i./ha and chlorantraniliprole 18.5 SC @ 30 g a.i./ha. Further the effect of insecticides on natural enemies revealed that the insecticides namely spinosad 45 SC @ 125 g a.i./ha (1.76) and, abamectin 1.9 EC @ 3g a.i./ha (1.69), chlorantraniliprole 18.5 SC @ 30 g a.i./ha (1.62) and novaluron 10 EC @ 75 g a.i./ha (1.51) were found safer to the predatory coccinellids. Whereas, flubendamide 39.35 SC @ 60 g a.i. /ha was moderately toxic to coccinellids. Cypermethrin 25 EC @ 62.50 g a.i./ha was found detrimental to the natural enemies.
