Abstract: 
The cereal leaf beetles (Oulema spp.) were rare in Hesse in 1986. The mymarid wasp Anaphes flavipes parasitised 8 to 19 percent of Oulema-eggs on cereals, 12 percent on couch grass and zero on Bromus spp. Larval parasites (presumably 3 species) parasitized 60% of O. lichenis cocoons. A. flavipes was reared in the laboratory in eggs of both Oulema spp. up to the fifth generation. One female produced a progeny of 22 at maximum, at the average 8.6. From one Oulema-egg 2.8 parasites emerged at the average, 10 to 13 days after oviposition by the parasites, at temperatures between 22 and 25.degree. C. The optimal number of parasites should be achieved with 20 to 30 Oulema-eggs exposed to 3 to 4 parasites (including 1 male). Unmated females have male progeny only. The possibilities of using A. flavipes for biological control of cereal leaf beetles in the field are discussed.
