Abstract: In 1990 19 individuals of Ceranisus menes (Walker) (Hymenoptera Eulophidae) were collected in a wild meadow in the hills near Bologna and Faenza (ltaly). A C. menes laboratory rearing was set up using these 19 parasitoids, all of witch proved to be females. Only 5 C. menes females, 3 collected as adults and 2 as parasitized thrips larvae, parasitized Frankliniella occidentalis (Pergande) (Thysanoptera Thripidae).
Of the 60 subsequent pupae, 30 females emerged and 7 were used later in preliminary rearing trials at 25°C: 78% of C.menes females emerged 28 to 34 days after parasitization (37% after 29 days) and 22% 46 to 64 days (N=56); emergence percentage from pupae was 56% (N=219). Thrips larvae were observed feeding on both parasitized and unparasitized larvae. Two rearing methods were used: 1) a modified Murai method and 2). on green bean pods. C. menes was reared for at least 20 generations on F. occidentalis. Later collections from flowers of wild vegetation proved that C.menes is a regularly occurring as a parasitoid of thrips in Northern and Central Italy.
