abstract
The biology of leaf webber and capsule borer, Antigastra catalaunalis was studied on sesame variety TKG-22. The results revealed that the female moths laid eggs singly on the lower surface of the leaves along the midrib and veins, in between the floral buds, inside the flowers and in stem and capsules. The average developmental period of first, second, third, fourth and fifth instar larvae were 103.75, 32.85, 23.90, 60.40 and 65.35 hours respectively. The total larval period ranged from 9.85 to 10.24 days and average 9.99 days. Pupa turned into brown before eclosion of the adult. The length and breadth of pupa varied from 6.87 to 7.39 mm with an average of 7.11 mm and 1.18 to 1.30 mm with an average of 1.23 mm, respectively. The pre-oviposition period of female moth varied from 9.85 to 10.30 hours with an average of 10.05 hours. The oviposition period of A. catalaunalis females ranged from 4.30 to 4.60 days with an average of 4.43 days. The total life cycle of A. catalaunalis varied from 18- 40 days.
