| 摘 要： | 通过林间调查与室内饲养相结合的方法,对白蜡吉丁啮小蜂（Tetrastichus planipennisiYang）的生物学特性进行了初步研究。结果表明,该寄生蜂在吉林省长春市年发生3-4代,以老熟幼虫在寄主幼虫的蛀道内越冬;不同时期的成蜂性比（♀∶♂）为2.39∶1-5.06∶1,平均为3.04∶1;补充20%蜂蜜水的雌雄成蜂平均寿命分别为16.2±1.24 d和7.00±1.19 d,比取食清水的雌雄成虫分别长6.90 d和1.33 d。平均自然寄生率为35.72%,最高可达76.92%。 |

| Abstract: | Through methods of forest investigations and laboratory rearing,the biological characteristics of Tetrastichus planipennisi were studied.Result shows that: the parasitized host larvae which have 3-4 generations per year in Changchun city overwinter in the bored tunnel of trunk of host larvae as mature larvae;the sex ratio of female to male is 2.39:1-5.06:1 in different periods and the average sex ratio of that is 3.04:1;the average life-span of female and male adults which were fed with 20% honey-water solu... |
