摘　　要：We examined the life-history traits of insect inclusions in bamboo galls induced by the gall maker, Aiolomorphus rhopaloides Walker (Hymenoptera: Eurytomidae) in a bamboo stand. Eight hymenopteran and one dipteran species were detected using soft X-ray photography of the galls and insect emergence from the galls. Aiolomorphus rhopaloides was the gall maker and Diomorus aiolomorphi Kamijo (Torymidae) was its inquiline.Homoporusjaponicus Ashmead (Pteromalidae) and Eupelmus sp. (Eupelmidae) are likely to be primary parasitoids of the larva ofA. rhopaloides. Eurytoma sp. (Eurytomidae),Sycophila sp. (Eurytomidae) and Norbanus sp. (Pteromalidae) are thought to be facultative hyperparasitoids. Cecidomyiidae sp. is thought to be the inquiline ofA. rhopaloides galls.Leptacis sp. (Platygastridae) probably parasitizes the larvae of Cecidomyiidae sp. Larvae of A. rhopaloides appeared in galls in July with the percentage of larvae decreasing in September, before overwintering as pupae. The growth ofD. aiolomorphi larvae within galls may be faster than that ofA. rhopaloides. The percentage of parasitoids in galls was low in July, but increased until winter. Aiolomorphus rhopaloides and D. aiolomorphi emerged from mid-April to early May, and from late April to early June, respectively. From overwintering galls, six other hymenopteran species emerged between late May and late June; one dipteran Cecidomyiidae sp. emerged between mid-April and early May.We examined the life-history traits of insect inclusions in bamboo gallsinduced by the gall maker, Aiolomorphus rhopaloides Walker (Hymenoptera: Eurytomidae) in a bamboostand.
