The comparative seasonal biology studies of banana leaf roller, Erionota torus evans under laboratory conditions

Abstract

The results of comparative seasonal biology studies of Banana leaf roller, Erionota torus Evans revealed, female skipper laid eggs in cluster on under side of the banana leaves. During rainy season, the incubation, total larval and pupal period ranged from 7-9 days, 26-33 days and 10-12 days, respectively. The total life cycle (egg to adult) varied between 52-67 days for male and 55-70 days for female. However, slight variation was observed during winter season with 7-10 days, 27-36 days and 11-13 days, respectively for incubation, larval and pupal period. The total life cycle (egg to adult) ranged from 55-72 days for male and 58-75 days for female.
