Abstract:

The biology of brinjal shoot and fruit borer, Luecinodes orbonalis Guenee was studied in the Biocontrol laboratory, Department of Agricultural Entomology, N. M. College of Agriculture, Navsari Agricultural University, Navsari, Gujarat during 2016-17. The eggs of brinjal shoot and fruit borer were elongated and oval with creamy white colour. The incubation period ranged from 2 to 3 days (2.36 ± 0.49 days) while, hatchability was 60.0 per cent. The colour of neonate larva was dirty white whereas, full grown larva was pinkish brown in colour. Larvae passed through five distinct instars. The duration of first, second, third, fourth and fifth instar larva was 1.00 ± 0.00, 1.06 ± 0.25, 1.73 ± 0.44, 2.66 ± 0.47 and 3.53 ± 0.50 days, respectively. Average length of first to fifth instars larva was 0.85 ± 0.01, 2.01 ± 0.07, 4.04 ± 0.85, 8.09 ± 0.79 and 14.64 ± 1.26 mm, whereas, average breadth was 0.16 ± 0.01, 0.39 ± 0.05, 1.01 ± 0.04, 1.80 ± 0.29 and 2.97 ± 0.24 mm, respectively. The total larval period was completed in 10.00 ± 0.69 days. The average pre-pupal and pupal period was 1.30 ± 0.46 and 5.76 ± 0.77 days, respectively. The adult moth was white in colour with blackish brown head and thorax. The abdomen of female was swollen and seemed to be ovate in structure with abdomen tip tapering and pointed towards the end whereas, in the males, it was thinner, cylindrical and blunt. The average fecundity of the female recorded 126.66 ± 2.87 eggs. Longevity of female was 4.61 ± 0.50 days while that of male was 2.33 ± 0.49 days. The total life cycle occupied 22 to 28 days (24.11 ± 1.84 days) by female and 20 to 26 days (21.66 ± 2.22 days) by male.
