| Abstract: | Torymus bedeguaris, a newly recorded species in China, is one of main predators for Diplolepis rosae. It is a solitary parasite, whose life history has better consistency with that of D. rosae. The parasitic rate of T. bedeguaris reaches up to 94.0%, with the average rate of 78.6%. It has two generations a year in Lanzhou, and its mature larvae overwinters in the gall of D. rosae. In the next mid-May, overwintering generation emerges into adults, in mid-July the first-generation does. The males emerge before the females and the sex ratio of the former to the latter is 2.2 to 1. |
