在显微镜下连续观察,用电影摄影机跟踪拍摄,及试验研究的结果证实:松毛虫赤眼蜂两性生殖,产生雌雄子代;孤雌生殖仅产雄性子代。寄生于同一柞蚕卵内的松毛虫赤眼蜂,雄蜂较雌蜂早1～1.5天羽化。雄蜂羽化后,在寄主卵内即与刚脱下蛹包膜、尚未展翅的雌蜂,或发育后期的雌蛹交尾。羽化前5小时的雌蛹中,有59％以上的个体已经受精,羽化后可产生雌雄两性子代;但羽化前24小时以上的雌蛹,虽能观察到雄蜂有与之交尾的动作,但其产生的子代均为雄性。雌蜂在卵内交尾后,咬破卵壳出来。未见到前人所报道的雄蜂先咬破卵壳,在寄主卵外等待雌蜂交尾的现象 雌蜂产卵时,产卵管在寄主卵壳上朝左右两个方向轮流旋转钻孔,其旋转角度不超过360度,转速1～2转/秒。同时由产卵管分泌一种液体。
Continuous observation under the microscope, with the film camera tracking shots, and the results of the pilot study confirmed: Trichinella Trichogramma gender reproduction, produce male and female; parthenogenesis only male offspring. Trichocalypsis parasitic eggs in the same Trichogramma Trichogramma, drone than females earlier 1 ~ 1.5 days feather. After the emergence of male bee, in the host egg that just take off the pupae, females have not yet spread their wings, or the development of female pupal mating. More than 59% of the female pupae in the first 5 hours of eclosion were already fertilized, which could produce male and female offspring after eclosion. However, female pupae with 24 hours or more before eclosion could observe mating action of male bees The resulting offspring are male. The female bees bite the egg shell after mating in the egg. Did not see the previously reported drone first bite the egg shell, wait outside the host egg mating phenomenon of female bees females spawn, the ovipositor egg shell rotation in both directions left and right turn drilling, which Rotation angle does not exceed 360 degrees, speed 1 ~ 2 rev / sec. At the same time, a fluid is secreted by the ovipositor.
