Bionomics of leaf and capsule borer, Antigastra catalaunalis (dup.) Infesting sesame, Sesamum indicum (Linn.).

Abstract

Investigations on “bionomics and biointensive management of sesame leaf and capsule borer, Antigastra catalaunalis (Dup.).” were conducted at Agronomy farm and Department of Entomology, S.K.N. College of Agriculture, Jobner during Kharif, 2015 and 2016. A. catalaunalis were recorded as major insect pests of sesame during both the years of study. The different parameters of bionomics of A. catalaunalis have been presented as egg, larva, pupa and adult. The total life cycle of A. catalaunalis varied from 21 to 39 days with an average of 28.1 days. The incubation period varied from 47- 73 hours with an average of 60.6 hours. The larva passed through five instars on sesame leaves under laboratory conditions. Duration of larva was 8.21-12.16 days. Duration of the pre-pupa ranged between 21-121 hours with an average of 100.7 hours and that of pupa 3.10-12.0 days with average 7.18 days. Longevity of adult male varied from 3-5 days with an average of 4.1 days, whereas females lived for 4 - 6 days with an average of 5.8 days.
