Shafiq* *Department of Plant Protection, Faculty of Agricultural Sciences, Aligarh Muslim University, Aligarh202 102, India. E-mail: mohdsansari@yahoo.com Online published on 27 December, 2012. Abstract Incidence of mustard aphid Lipaphis erysimi (Kaltenbach) varied significantly on different stages of crop growth as well as mustard based cropping system viz., mustard-wheat, mustardchickpea, mustard-coriander and mustard-fennel. The initial infestation of aphids begins at 55 DAS (Days after sowing) on sole crop while 85 DAS on intercrops. Highest infestation is obtained at 95 DAS on all rows of sole crop (mustard). Intensity of aphid was greatest on mustard-chickpea followed by mustardwheat, mustard-coriander and the lowest on mustard-fennel with greater yield.
