abstract
Investigations on “Seasonal incidence of sesame leaf and capsule borer, Antigastra catalaunalis (Dup.) in relation to environmental factors.” were conducted at Agronomy farm and Department of Entomology, S.K.N. College of Agriculture, Jobner during Kharif, 2015 and 2016. Antigastra catalaunalis were recorded as major insect pests of sesame during both the years of study. The infestation of A. catalaunalis commenced in the third week of August and reached its peak in the last week of August during 2015 and 2016, respectively. The correlation studies indicated that the A. catalaunalis population had significant negative correlation (r= -0.78) and (r= -0.68) with maximum temperature during both the years, while with minimum temperature and relative humidity had positive significant correlation (r= 0.88, r=0.87, respectively) and rainfall had non significant correlation during Kharif 2015. The A. catalaunalis population had non significant correlation with minimum temperature, relative humidity and rainfall respectively) during Kharif 2016.
