The field experiments on the efficacy of newer insecticides on sucking insect pests of groundnut was conducted at Regional Agricultural Research Station, Palem, of Nagarkurnool district, Telangana, India during rabi, 2021-22 in a randomized block design with eight treatments viz., Tolfenpyard 15% EC at 1.5 ml L-1 and Tolfenpyard 15% EC at 2 ml L-1, Tolfenpyard 15% EC at 2.5 ml L-1, Spinetoram 11.7% SC at 0.5 ml L-1, Thiamethoxam 12.6+ Lambdacyhalothrin 9.5% ZC at 0.4 ml L-1, Clothianidin 50% WDG at 0.3 g L-1, Afidopyropen 50g/IDC at 2ml L-1 and Sulfoxaflor 21.89% SC at 0.5 ml L-1. Among all the insecticides tested clothianidin@ 0.3 g L-1 worked very effectively in reducing the population of leafhoppers and thrips. The other effective treatments were afidopyropen at 2ml L-1 and tolfenpyard@ 2.5 ml L-1 followed by tolfenpyard 15% EC at 2.5 ml L-1, tolfenpyard at 2.5 ml L-1, thiamethoxam+ lambdacyhalothrin at 0.4 ml L-1. The treatment spinetoram at 0.5 ml L-1 was less effective on the sucking pest. The highest Incremental Cost Benefit Ratio (ICBR) is recorded from the plots sprayed with clothianidin@ 0.3 g L-1 (1.4. 83) followed by afidopyrofen@ 2ml L-1 (1: 3.94).
