摘要
光肩星天牛（Anoplophora glabripennis）在我国严重危害杨树（Populusspp）、柳树（Salix spp．）和榆树（U／mus pumila）等园林绿化和防护林树种，是一种重大的蛀干害虫，由于其隐蔽的生活方式和较长的生活史使对该害虫的防治受到了很大的限制。
The Asian long-horned beetle, Anoplophora glabripennis is a polyphagous xylophage native to Asia. This beetle is the most serious pest in the Three-north Areas of China. Dastarcus helophoroides plays an important role in biological control of the Asian long-horned beetle. In order to determine the probability of introducing this natural enemy to control A. glabripennis in the northwest of China, the overwintering survival of D. helophoroides in north China is a most important issue which should be understood. The overwintering place and survival of D. helopho- roides were investigated respectively. The supercooling points of overwintering and laboratory strains of this parasitic beetle were assayed. The results indicated that most of this parasitic beetle chose the long-horned beetle pupa cell and the gallery as their overwintering place. A small proportion of them completed their overwintering process be- neath the bark. Over 50% proportion of this beetle can complete the overwintering process successfully. Further- more, the cold tolerance of overwintering strain was much stronger than that of the laboratory strain. These findings suggested that D. helophoroides can successfully accomplish the overwintering process in northwest of China. This might provide a support for introducing D. helophoroides to control the Asian long-homed beetle in these places.
