Maize is an important cereal crop after wheat and rice, grown all over the world including Pakistan. Maize crop is attacked by several insects pests among them maize stem borer, Chilopartellus is key pest that cause huge losses. Different management tactics are adopted tocontrol pest and minimize the yield reduction. Anexperimental study was conducted at Insect pest management program in National AgriculturalResearch Centre (NARC), Islamabad during 2017 to check the concentration of stem damage by C. partellusin maize field and parasitism of Trichogramma chilonis reared on C. partillus eggsunder laboratory conditions. The results showed that maximum tunnels were recorded in Maize Germplasm (MBR-10) entry 1 (2.75) followed by row 4 (2.40) while minimum in the row 3 (0.42) followed by row 9 (1.00). The rates of adult emergence on the eggs of Chillo partellus was 83.92% followed by 78.71% and 71.21% respectively after 24, 48 and 72 hours.

Keywords: Maize, Maize Germplasm (MBR-10), Stem borer, Parasitism, Trichogramma chilonis.
