Ecobehaviour of Pomegranate Fruit Borer, Deudorix isocrates (Fab.) [Lycaenidae: Lepidoptera] Under Orchard Ecosystem

Studies on the bioecology and behaviour of the pomegranate fruit borer, Deudorix isocrates (Fab.) revealed that the insect multiplied primarily on pomegranate crop under orchard agro-ecosystem. Guava and sapota also served as host crops to certain extent whenever the main host plant pomegranate is wanting or less suited for development of the larvae. Its damage noticed was severe in 30–50 days old fruits of pomegranate and the adults preferred 30–50 days old fruits for egg laying and most of the eggs were laid on the calyx portion of the individual fruits. The severity of damage was noticed between April to August months. Fourth and fifth instar larvae caused the maximum damage to fruits and total rejection of fruits is not uncommon on infestation by these insects. Attempting application of physical barriers such as covering the 30–50 days old fruits alone, clipping off calyx cup of flowers immediately after pollination will help to reduce the egg load on the fruits and also damage level as a non-chemical management strategy.
