    Description / Table of Contents: Résumé Planococcus citri (Risso) est un des principaux ravageurs des vergers de citrus indiens. Pour lutter contreP. citri, un parasite Encyrtidae,Leptomastix dactylopii How. a été introduit de la région des Caraïbes en 1983. Le parasite a été multiplié et des lâchers inoculatifs ont été réalisés dans 2 vergers de citrus choisis où les infestations sur fruits (oranges douces, limes sans pépins, limes acides) s'échelonnaient de 38 à 65 p. 100. Il résulta de l'établissement du parasite dans les 2 vergers de lâchers, le contrôle complet de la Pseudococcine en l'espace de 3 à 4 mois. En conséquence, nul traitement insecticide ne fut nécessaire au cours des saisons suivantes pour lutter contreP. citri.
    Notes: Abstract Planococcus citri (Risso) is one of the major pests of citrus orchards in India. For the control ofP. citri, an encyrtid parasite,Leptomastix dactylopii How. was introduced from West Indies in 1983. The parasite was mass bred and inoculative releases were made in 2 selected citrus orchards where infestation of mealybug on fruits (sweet orange, seedless lime and acid lime) ranged from 38 to 65 per cent. Establishment of the parasite in the 2 release orchards resulted in complete control of the mealybug within 3 to 4 months. No insecticidal sprays were required subsequently for the control ofP. citri in the following seasons.
