Efficacy of some newer insecticides were tested against the groundnut leaf miner Aproaerema modicella (Deventer), tobacco caterpillar Spodoptera litura (F), gram pod borer Helicoverpa armigera (Hubner) and natural enemies (coccinellids) of groundnut. Tolfenpyrad @ 2.5ml/ l was significantly superior in controlling defoliator pests. The next best treatments were tolfenpyrad @ 2ml/ l, spinetoram @ 0.5ml/l, tolfenpyrad @ 1.5ml/ l, thiamethoxam+ lambdacyhalothrin @ 0.4ml/ l. The highest incremental cost benefit ratio (ICBR) was obtained in the treatments with tolfenpyrad @ 2.5ml/ l.
