Studies on population dynamics of Chilo partellus Swinhoe infesting sorghum was made during 2006-07 and 2007-08 in rabi season at Agricultural Research Station, N.A.U., Tanchha, dist. Bharuch. The incidence of pest began from fourth week of November and continued up to first week of February with a peak activity in second and fourth weeks of December. The abiotic factors, maximum, minimum and average temperature had significant negative association, while humidity, rainfall, rainy days and sunshine hours, wind velocity and evaporation had no significant influence on C. partellus on rabi sorghum.
