摘要
我们于1984～1985年用人造寄主卵繁殖荔枝蝽蟓卵寄生蜂——平腹小蜂(Anastatus japonicus Ashmead)成功后,相继筛选出最佳卵壳材料为32—36微米厚的聚丙烯膜,最佳培养基配方为柞蚕蛹血淋巴44.4％、10％麦乳精液22.2％、鸡蛋黄22.2％、尼氏盐11.2％。以上资料己登载于第二届国际赤眼蜂及其它卵寄生蜂学术讨论会论文集。本文报导了用人工体外培育法首次观察到的平腹小蜂在人造卵上产卵过程以及连续三代人工体外培育平腹小蜂的结果:除化蛹率外,各代间在寄生率、孵化率、羽化率、展翅率等方面都未表现出明显的差别,且各代以人造卵育出的蜂在身体大小,寿命及繁殖力方面比用柞蚕卵育出者基本相似或更优。
Anastatus japonicus(Ashmead)is an egg-parasit, widely used in South China for controlling litchi stink bug, Tessaratoma papillosa(Drury), the most important insect pest of litchi and lohgan. The egg parasite can be reared in artificial medium, contained in polypropylene capsule with diameter 0.3 cm. The length and width of the ovipositor is 1.155+0.0529 mm and 0.6401±0.0356 mm respectively. It is the first time to see clearly all the process of oviposition in the transparent artificial 'host-egg'. The mean time from ovipositor drilling to with-drawal after ovulation at each oviposition in the artificial 'egg' is 5 min and 15 s, but in the egg of Philosamia cynthia ricini or Antheraea pernyi, it is 10 or 54.5 min respectively. In the artificial 'egg' female lays one egg at each oviposition mostly, occasionally 2—3 eggs but only one developed. A. japonicus has been reared in artificial 'eggs' for three generations with better viability than in the eggs of Anthcraea pernyi.
