Abstract
The biology of Sesamia inferens (Walker) was studied at 25±1 °C
and 70±5 per cent relative humidity on PMH 1 maize hybrid. The incubation period
was 6.82±0.05 days. There were six larval instars and the larval development was
completed in 29.95±0.16 days. The duration of instars I-VI was 4.17±0.09,
3.60±0.08, 4.47±0.02, 4.40±0.03, 6.18±0.06 and 7.13±0.05 days, respectively. The
pre-pupal period was 2.83±0.02 days. The male and female pupa had duration of
8.05±0.12 days and 10.33±0.16 days, respectively. The adult emergence was
93.02±0.01 per cent, with a sex ratio of 1:1.05. The males had shorter longevity
of 3.92±0.23 days, while females had 5.05±0.28 days. The pre-oviposition,
oviposition and post-oviposition period was 1.11±0.10, 2.96±0.19 and 0.79±0.10
days, respectively. The fecundity was 211.92 ±11.92 eggs with 53.69±10.78 eggs
per cluster. The egg hatchability was 92.19±0.01 per cent. The total life cycle
was completed in 47.65±0.24 days (Male) and 49.93±0.21 days (female). The
observations on the biology will help in developing efficient strategies to
manage S. inferens on maize in the north western plains of
India.
