Abstract

Mealybugs are injurious to pomegranate (Punica granatum) in India, Sri Lanka, South Africa, Florida, Iran, Palestine, Israel and USSR. Both nymphs and adult female mealybugs caused considerable damage to the pomegranate by sucking the sap from the leaves, flowers and fruits, resulting in yellowing of leaves and shedding of flowers and tender fruits. The incidence of mealybugs was more from March onwards and gradually reached to peak during second fortnight of April in North Karnataka, India. From June onwards, there was gradual decline in mealybug population. Among all treatments, dimethoate in addition with fish oil rosin soap recorded higher per cent reduction of mealybugs. Biological control is effective unless disrupted by ants and insecticidal application. Cryptolaemus montrouzieri supplements other local natural enemies in clearing the mealybug species on pomegranate in India. The encyrtid parasitoid Tetracnemoidea indica (Ayyar) played a significant role in reducing the mealybug population on pomegranate in India. Leptomastix dactylopii How. and Coccidoxenoides perminutus (Timberlake) were found to be effective in suppressing the populations of P. citri on pomegranate.
