| 中文摘要: |
| 玫瑰瘿长尾小蜂( Torymus bedeguaris )为中国新记录种, 是玫瑰犁瘿蜂的主要天敌之一, 单寄生, 其生活史与玫瑰犁瘿蜂吻合性极好, 寄生率最高可达94.0%, 平均寄生率为78.6%; 在兰州一年发生2代, 以老熟幼虫在玫瑰犁瘿蜂虫瘿内越冬, 5月中旬越冬代成虫羽化, 7月中旬第一代成虫羽化, 雄虫先于雌虫羽化, 雌雄比为2.2∶1。 |
| 英文摘要: |
| 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. |
