Abstract

Pseudococcids (Homoptera, Coccoidea, Pseudococcidae) within the context of integrated control in citrus groves round the Mediterranean.

Abstract

Plancoccus citri Risso is the most injurious of the mealybugs on citrus in the Mediterranean region. Details are given of the chemical treatments applied in France for the control of this pest on lemon, on which about 2% of the fruits are infested. Attempts to obtain control are made more difficult by the need to adopt measures to control Ceratitis capitata (Wied.). Exposure to sublethal doses of compounds applied to control the fly has lead to resistance in the coccid (in certain groves in Morocco) and appears to increase fecundity. Despite difficulties of acclimatisation in some areas, Cryptolaemus montrouzieri Muls. can afford good control of Planococcus citri (Risso) and its use, together with Leptomastix dactylopii How., is recommended.
