Efficacy of newer insecticides against sucking insect pests, whitefly (Bemisia tabaci), Jassid (Empoasca kerri) and thrips (Caliothrips indicus) of mungbean [Vigna radiata (L.) Wilczek] Abstract A field experiment was conducted to find out the effective dose of some newer insecticides for the management of sucking insect pests of mungbean viz., whitefly (Bemisia tabaci), jassid (Empoasca kerri) and thrips (Caliothrips indicus). The treatments of experiment were Diafenthiuron 50 WP @ 187.5g

Check) @ 25g a.i./ha and Triazophos 40 EC (Std. Check) @ 500g a.i./ha. The results of experiment revealed that among the tested insecticides, the treatment T3 (Diafenthiuron 50 WP @ 312.5 g a.i./ha) was found most effective resulting in 85.9% and 77.8% reduction of whitefly and thrips population respectively. The treatment T5 (Spiromesifen 240 SC@ 120 ml a.i./ha) was found most effective against jassid resulting in 77.5% reduction of population.
