Abstract
Dichocrocis punctiferalis Guen. is a polyphagous pest with twenty two species of alternate host plants. Moths have punctilious requirements for egg laying in captivity and it was found that an ambient temperature of 22°C-31°C and relative humidity in the range of 50-90% were favourable for oviposition. Out of the five larval instars, 4th and 5th were voracious feeders. The life cycle was completed in 33-52 days under laboratory conditions. Seven saprophytic dipteran flies were found associated with the shoot borer. Among the predators and parasites, the dermapteran Euborellia stali (Dohrn.) and the mermithid nematode have some significant role in controlling the shoot borer population in the field.
