Abstract:

Field experiment was conducted in Instructional-Cum-Research (ICR) farm, Assam Agricultural University, Jorhat during rabi 2018& 2019 to investigate the insect pests and natural enemies of mustard. During the period of present investigation, a total number of four insect pests from four different families viz, mustard aphid, Lipaphis erysimi (Kalt.); mustard sawfly, Athalialugens proxima (Klug); Flea beetle, Phyllotreta Cruciferae (Goeze); cabbage butterfly, Pieris brassicae (Linn.) were recorded at different stages of mustard crop. On the other hand, total three predators viz, coccinellid beetle (Coccinella transversalis (Fab.) and Harmonia axyridis (Fab.), green lacewing, Chrysoperla carnea (Stephens); syrphid fly, Xanthogrammas cutellaris (Fab.) and one aphid parasitoid, Diaeretiella rapae (M’lntosh) were recorded as major natural enemies on insect pests of mustard. However, out of both coccinellids C. transversalis was dominant and considered as major predator of aphids.
