Author(s): Suman Devi and Pala Ram
Abstract: The present study was conducted at Chaudhary Charan Singh Haryana University, Hisar, and experimental area of the Department of Entomology during the Kharif season of 2016 and 2017. The pooled data of both the years revealed that maximum population of leafhopper (Amrasca biguttula biguttula) nymphs (3.94 nymphs/leaf) was recorded in late sown while minimum population (2.91 nymphs/leaf) was recorded in early sown cotton. In case of thrips (Thrips tabaci Linderman), the population of thrips adults was highest (3.99 adults per leaf) in late sown crop while population was least (2.89 adults per leaf) in normal sown cotton. In case of whitefly (Bemisia tabaci Gennadius), the population of whitefly adults was highest (4.46 adults/leaf) in late sown while population of whitefly adults was least (2.88 adults/leaf) in early sown cotton.
