Orlinski, T. Bassova] Lutte biologique contre la mouche blanche des agrumes Dialeurodes citri Ashmead [ Hom. Aleyrodidae] par introduction d'Encarsia lahorensis Howard [ Hym. : Aphelinidae ] dans les pays de l'ex-URSS The citrus whiteflyDialeurodes citri Ashmead is one of the most important insect pests of citrus groves on the Black Sea coast of the Caucasus and on the Caspian Sea coast of the Talysh Mountains; it is the most important citrus pest of trench cultivation in Central Asia and in glasshouses. The parasitoidEncarsia lahorensis Howard was introduced in 1983 into Russia (Moscow) from Pakistan. It was reared in a laboratory of the All-Russian Plant Quarantine Institute. The parasitoid was released as follows: in 1985 in Adzharia (Batumi); in 1987 in a glasshouse in Russia (near Moscow) and in 1988-1990 in Central Asia - Uzbekistan (Namangan) and other regions. It established well in all places of release. The rate of parasitization ofD. citri byE. lahorensis reached 50-52% in the orchard in Batumi five years after the first release, 56-60% in the glasshouse in Moscow three years after the first release, and 50% in trenches in Namangan two years after the first release. Levels of the pest populations decreased dramatically in the glasshouse and trenches. The efficiency of the additional feeding ofE. lahorensis adults on the host larvae was evaluated to 26 to 60%. The differences between populations of the parasitoid in the three different areas are discussed.
