Abstract

Phyllonorycter medicaginella (Lepidoptera, Gracillariidae) and its parasitoids (Hymenoptera, Eulophidae) in the middle Volga River basin.

Abstract

Fifteen species of parasitoids - Chrysocharis idyia (Walker 1983), Ch. laricinellae (Ratzeburg 1848), Ch. submutica Graham 1963, Ch. viridis (Nees 1834), Hemiptarsenus ornatus (Nees 1834), Neochrysocharis formosa (Westwood 1833), Pediobius cassidae Erdos 1958, P. metallicus (Nees 1834), Pnigalio nemati (Westwood 1838), P. mediterraneus Ferriere & Delucchi 1957, P. pectinicornis (Linnaeus 1758), P. soemius (Walker 1839), Rhicnopelte crassicornis (Nees 1834), Sympiesis gordius (Walker 1839) and Hyssopus sp. n. - were reared from Phyllonorycter medicaginella on Melilotius officinalis for the first time. Hyssopus simbirskiensis sp. n. reared from Ph. medicaginella is described. Eight ectoparasitoids species (H. ornatus, H. simbirskiensis sp. n., Rh. crassicornis, P. mediterraneus, P. nemati, P. pectinicornis, P. soemius, and S. gordius) attack all larval instars of Ph. medicaginella. Seven endoparasitoids (P. cassidae, P. metallicus, Ch. idyia, Ch. laricinellae, Ch. submutica, Ch. viridis, and N. formosa) attack only 4-5 larval instars.
