Two experiments were conducted to study the effect of 21 sunflower genotypes on the parasitism efficiency of Trichogramma chilonis on Helicoverpa armigera under screen house conditions. Pooled analysis of data revealed significant difference in percent parasitism of H. armigera eggs by T. chilonis on these genotypes. Highest parasitism was observed on sunflower hybrid MSFH 17 (53.50%). Second best performance was on Morden (42.50%), followed by RHA-274 (41.00%) and hybrid KBSH 1 (38.00%).
