Biology and morphometry Spodoptera litura Fabricius on tomato

Nagamandla Ramya Sri and Shantanu Jha

The present investigation was conducted to study biology and morphometry of Spodoptera litura on tomato leaves. Larvae were brought from field and reared in glass jars by providing tomato leaves at research laboratory, BCKV during 2016-17 at three different temperatures, 20 0C, 25 0C and 30 0C with RH 75 ± 5 %. At 20 0C, total larval period completed in 41.8±3.56 days while it took 25.8 ± 0.67 days and 16.3 ± 0.83 days in 25 0C and 30 0C respectively. Total developmental period completed in 60.4 ± 3.13, 41.6 ± 1.08 and 30.1 ± 1.29 days in 20 0C, 25 0C and 30 0C respectively. As the temperature increased, number of days required for development decreased. The length of different larval instars increased from 3.48 ± 0.08 mm to 36.26 ± 0.24 mm and breadth from 0.3 ± 0.007 mm to 4.1 ± 0.02 starting from first instar to fifth/sixth instar.
