Establishment of Leptomastix dactylopii How. (Hym.: Encyrtidae) in Karnataka for control of Planococcus citri (Risso) (Hom.: Pseudococcidae) of coffee.
The parasitoid Leptomastix dactylopii was mass-reared and released in coffee estates in Karnataka, India, during 1984-90 for the control of Planococcus citri, P. lilacinus and P. minor. About 158 000 adult parasitoids were released on 49 coffee estates. The encyrtid was recovered from 29 estates; persistence was observed in only 19 estates where the predominant pseudococcid was P. citri. Parasitism ranged between 0 and 85%.
