ABSTRACT
To observe the incidence and damage of Agrotis ipsilon on different sunflower genotypes (Hysun-777, XF-263, Award, T-562, 9706, 9705, 9707, PSF-025, Parsun-1, 1435, JH1 99S, JH2 99S, PNSF1 and Hysun-33) a field experiment was conducted under UGC/UAAR Sunflower Project.Sunflower genotypes, 9706, JH2 99S and PNSF 1 showed somewhat partial resistance to A ipsilon. XF 263 and 9707 showed somewhat more susceptibility than Hysun-33.All other genotypes did not differ from Hysun-33 and thus were susceptible to A. ipsilon. The number of larvae of A. ipsilon and damage done by them were significantly and positively correlated. The genotypes which showed some resistance to the attack of A. ipsilon could be included in the programmes evolving genotypes resistant to the attack of this pest and thus pollution problems due to heavy use of insecticides could be minimized.
