摘要

Sixteen species of Eulophidae were reared from Chromatomyia horticola (Goureau) collected from 14 host plants in the Middle Volga Basin (Russia). Chrysocharis viridis (Nees), Closterocerus trifasciatus Westwood, Diglyphus pusztensis (Erdos), Minotetrastichus frontalis (Nees), Neochrysocharis aratus (Walker), Pediobius cassidae Erdos, and Pnigalio pectinicornis (Linnaeus) are new host records. Two parasitic species, D. isaea (Walker) and P. metallicus (Nees), were dominant. The pre-imaginal stages of both dominant (ecto- and endoparasitoid) species are illustrated. The sex ratio between the ecto- and endoparasitoids differed. In June/July, there were about threefold more females in ectoparasitoids than in endoparasitoids. These differences in sex ratio were not related to the plant species only. The endoparasitoid species were found on all species of host plants of C. horticola, whereas the ectoparasitoid species were restricted to about half the plant species. Diglyphus isaea and Pediobius metallicus are very important regulating species against leaf miner pests such as C. horticola.
