Abstract
The Life cycle of maize stem borer, Chilo partellus (Swinhoe) was studied in in vitro conditions. Development of stem borer undergoes following stages like egg, larvae, pupa and moth. The egg incubation period ranged from 3 to 6days, larval stage was observed in five instars. The mean value of I, II, III, IV and V instars showed 3.8±0.16, 5.2±0.02, 6.1±0.06, 7.35±1.5, and 10.12±0.29days, respectively and complete larvae period ranged from 42 to 49days. Pupae stage was observed in 8–9days. The pre-mating and mating period was found at 9.10±1.20 and 5.14±1.08h while egg laying period in 4.1±1.32days respectively. Fecundity rate of stem borer is from 262 to 657 eggs. The life span of adult male (3-7) and female (3-8) days was observed with a mean of 6.30±0.85 and 5.10±0.69days respectively. Life cycle of stem borer gets completed in 47 to 51days. Development of quality insects in required quantities at different developmental stages and their timely supply plays an inevitable role particularly for insect-breeding resistant programs. Hence to meet these challenges we had tried to standardize an artificial diet with cost effective to rear Chilo partellus under in vitro conditions.
