Biology and management of guava bark eating caterpillar (Indarbela tetraonis Moore)

An experiment on the biology of guava bark eating caterpillar (Indarbela tetraonis Moore) was conducted during 2012–13 at College of Horticulture, Bidar. Eggs were 0.67 to 0.73 mm long and 0.42 to 0.46 mm wide and they hatched in 7 to 11 days. Full grown larvae were 37 to 43 mm long and 6 to 8 mm wide. Larval duration was 274 to 298 days. Pupae were 11 to 15 mm long and 4 to 6 mm wide and the pupal period was 21 to 26 days. Male adult had wing span of 11 to 13 mm length and width of 20 to 24 mm. Female adult had wing span of 12 to 14 mm and width of 25 to 27 mm, Chlorantraniliprole 18.5 SC registered 100 percent control of the pest and highest yield of 24.85 t/ha and 25.00 t/ha during 2013 and 2014, respectively.
