摘要： Quednan,W.在1956、1960年连续发表文章,提出用生物学特性的标准来辨别赤眼蜂种或生态型,是具有一定科学意义的,但忽视雄外生殖器的构造。石井悌(Ishii,T.,1941)曾建议根据雄虫外生殖器的构造来区别几种赤眼蜂,并成立两个新种,即Trichogramma chilonis与T.jezoensis。因为制片的关系,雄外生殖器构造部分看不清楚,故他所绘的图是不甚完善的;作者现改进了制片方法,使赤眼蜂雄外生殖器内部构造,在显微镜检视下较为明显,特为补充,重行描述,并取北京地区玉米螟卵赤眼蜂(T.chilo-nis)与桃捲叶蛾卵赤眼蜂(T.minutum)作为典型,以资比较。同时发现这两种赤眼蜂的前翅毛列与稻螟赤眼蜂(T.japonicum)有显著的差异,特别是第6条纵毛行与第8条横毛行汇合处,前者有缺口,呈倒“八”字形,后者无缺口,呈倒“人”字形(图2,A、B);而且稻螟赤眼蜂雄外生殖器内不具“针”,故不同意Quednau把T.chilonis并入T.japonicum种内作为“同物异名”,而应该维持石井悌的T.chilonis 仍为—个独立种。 作者1963,年在辽宁省丹东市郊区于柞蚕卵内发现一种食胎赤眼蜂(Trichogramma embryophagum(Hartig)),在国内为初次记载,确是产雌性孤雌生殖型。
