Abstract

A survey of mealybugs and their associated natural enemies occurring in vineyards was conducted in 2003 and 2004 in different Tunisian grapevine-growing regions. Two mealybug species, the citrus mealybug, (Risso), and the vine mealybug, (Signoret), were found in all inspected vineyards. Parasitoids were recorded more frequently than predators as natural enemies of the two species. Four encyrtid primary parasitoids, (Girault), (Howard), (Girault) and (Timberlake), were recorded from mummified mealybugs collected in the field. , with a rate of parasitism of 80.3 %, was the most abundant parasitoid, followed by (12.1 %), (4.5 %) and finally (3 %). Two coccinellids, and ., were found associated with mealybugs.
