An experiment was conducted at Agriculture Research Farm, Department of Entomology, School of Agriculture, LPU, Punjab during rabi season 2020-22. Eggs of Chilo partellus were observed throughout the crop period, while Atherigona soccata maggot appeared in early stage crop of growth of maize. Both insects caused dead hearts where maximum damage percentage was obtained in 49^th SMW by C. partellus, whereas in 44^th SMW A. soccata caused damage during both the years. Natural enemies were present throughout the season and two peaks observed in coccinellids and spider population at 46^th and 51^st SMW. All physical factors had significant effect on maize stem borer population except temperature which had positive significant impact on A. soccata. This research will help to develop prediction model for sustainable maize pest management.
