Abstract: Mungbean (Vigna radiata L.) is third most important pulse crop of India after chickpea and pigeonpea (Singh and Singh, 2014). Sucking insect-pests (whitefly, jassid, thrips, pod sucking bug and aphid) are the major insect- pests not only reduce the vigor of the Mungbean plant by sucking the sap but also transmit viral diseases and affect adversely photosynthesis which ultimately causes yield losses (Kabir et al., 2014; Singh and Singh, 2014). Keeping in view of aforesaid facts and knowing the seriousness of problems, six newer insecticides viz., Imidacloprid 17.8 SL @ 210 g a.i./ ha, Spinosad 45 SC @ 73 g a.i./ ha, Emamectin benzoate 5 SG @10 g a.i. / h, Indoxacarb 14.5 SC @ 60 g a.i./ ha, Novluran 10 EC @ 30g a.i./, and Profenophos 50 EC @ 500 g a.i./ ha were evaluated against white fly (Bemisia tabaci) in Mungbean (Vigna radiata L.) during, Kharif- 2014. Among tested insecticides Emamectin benzoate 5 SG @10 g a.i. / ha showed maximum reduction in whitefly population which was at par with Indoxacarb 14.5 SC @ 60 g a.i./ ha followed by Profenophos 50 EC @ 500 g a.i./ ha and Spinosad 45 SC @ 73 g a.i./ ha at 7 and 14 days after spraying (DAS).
