Mealybug, Planococcus citri (Risso) is not only a serious pest of citrus but also at times serious on pomegranate, guava, grapes, etc. Insecticidal sprays have failed to give adequate control of this mealybug in recent years. Releases of an exotic parasitoid. Leptomastix dactylopii (How.)(Hym., Encyrtidae) in citrus orchards against P. citri in and around Bangalore have resulted in establishment of the parasitoid and complete control of mealybugs within four months in 1984-85 (Krishnamoorthy and Singh, 1987). Subsequently a survey was conducted by making field recoveries to evaluate the dispersal and establishment of the parasitoid in other areas on different crops, where releases were not effected.
