Online published on 4 January, 2018. Abstract An experiment on the biology of mango bark eating caterpillar Indarbela quadrinotata Walker during 2012–13 revealed that the eggs were 0.65- 0.70 mm long and 0.40- 0.45 mm wide, and hatched in 7- 10 days. Full grown larvae were 35 to 40 mm long and 5 to 7 mm wide, with duration of 273- 296 days. Pupae were 10- 13 mm long, 3 to 5 mm wide with the pupal period being 20- 25 days. Male adult had wing span 10- 12 mm long and 19- 22 mm wide, and lived for 4- 5 days. Female adult had a wing span of 11- 13 mm long, and 24- 26 mm wide and lived for 4- 5 days. Among the eight insecticides evaluated rynaxypyr 25SC gave 100% control with the highest yield (12.13 t/ha and 12.03 t/ha during 2013 and 2014, respectively).
