Abstract

Braconid parasitoids reared from Malus sieversii and Malus domestica trees in NW China infested by Agrilus mali Matsumura (Coleoptera, Buprestidae) are illustrated and discussed. Six species were found parasitising Agrilus mali in NW China, namely, Atanycolus ivanowi (Kokujev) (Braconinae), Doryctes undulatus (Ratzeburg), Pareucorystes varinervis Tobias, Polystenus rugosus Foerster, Spathius sinicus Chao, and Spathius brevicaudis Ratzeburg (Doryctinae). All listed species are newly recorded parasitoids of Agrilus mali. Pareucorystes varinervis and Spathius brevicaudis are new records for the Chinese fauna, but Spathius brevicaudis has been recorded from Taiwan before. Both sexes of Spathius brevicaudis are redescribed here to allow inclusion in the recent revision of the Chinese Spathius species. An identification key to the six braconid parasitoids of Agrilus mali in NW China is provided.
