The cabbage crop was found to be infested by five major pests i.e., tobacco caterpillar, Spodoptera litura (Fab.), diamond back moth, Plutella xylostella (Linn.), cabbage semilooper, Thysanoplusia orichalcea (Fab.), flea beetle, Phyllotreta chotanica (Duviv) and the aphids, Lipaphis erysimi (Kalt.) and Myzus persicae (Sulze). The tobacco caterpillar and diamond back moth population was maximum in the first and second week of February (5th and 6th SMW); the cabbage semilooper population was at its peak in the last week of January (4th SMW); the flea beetle population was maximum in the fourth week of February (8th SMW) and the aphid population was maximum in the second and third week of February (6th and 7th SMW) during rabi 2012-13 and 2013-14, respectively. Abiotic factors like temperature, relative humidity, extent and distribution of rainfall, influenced the infestation and stabilization of various insect pests in cabbage.
