Abstract

A field experiment was conducted on mustard aphid Lipaphis erysimi Kalt. and its natural enemies to document its seasonal incidence over four varieties of mustard during rabi season at the Instructional Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The aphids appeared in first week of January at the flowering stage, which peaked during 7th standard week were 115.5-155.0, 98.01-121.0, 75.5-108.6 and 55.80-86.49, aphids/plant on mustard variety Urvashi, Vardan, Varuna and Rohini, respectively. Correlation coefficients of incidence with weather factors have been worked out.
