摘要

Parasitism by parasitoid wasps on the larvae of Epinotia granitalis (Butler), which is a wood-injuring pest in coniferous plantations, was observed for 6 years in two plantation forests of Chamaecyparis obtusa (Sieb. et Zucc.) Endl. and Cryptomeria japonica (L.f.) D. Don that were adjacent to each other and consisted of trees of almost the same size. E. granitalis larvae were collected from early April to mid-May, then reared in glass bottles, and finally examined to determine whether or not the larvae had been parasitized. Five species of parasitoids were recorded; two of them were classified in Ichneumonidae, Campoplex spp. A and B, and others in Braconidae, Iconella repleta Papp, Bassus cingulipes Nees von Esenbeck, and Bracon spp. In all 6 years, parasitism was first observed around 20 April. Species composition of parasitoids differed greatly among years and between forests. In 1 year in each forest the percentage parasitism increased significantly with the sampling date, indicating that not all parasitoids attack the same developmental stage of E. granitalis. The mean percentage parasitism per year was significantly higher in the forest of C. obtusa [11.5(%) ± 5.7(SD)] than in the forest of C. japonica (3.0 ± 4.1). These results suggest that the efficiency of parasitoid adults in finding hosts differed between the two forests.

Don彼此相邻，由几乎相同大小的树木组成。从4月初到5月中旬收集了颗粒状大肠杆菌，然后将其放在玻璃瓶中饲养，最后检查以确定该幼虫是否已被寄生。记录到五种寄生虫;它们中的两个被归类为Campoplex spp的肺炎科。 A和B，以及Braconidae，Iconella repleta Papp，Bassus cingulipes Nees von Esenbeck和Bracon spp中的其他人。在全部6年中，寄生虫都是在4月20日左右首次出现的。多年间和森林之间，类寄生物的物种组成差异很大。在每个森林中，在1年中，寄生虫的百分比随采样日期的增加而显着增加，这表明并非所有的寄生虫都攻击相同的E. granitalis发育阶段。钝角梭菌林每年的平均寄生虫百分率显着高于粳稻林（3.0±4.1）[11.5（％）±5.7（SD）]。这些结果表明，两种森林中寄生类成虫寻找寄主的效率不同。
