两种赤眼蜂生殖特性和产卵器结构的比较

Comparing of Reproduction Characters and Ovipositor Structure of Two Trichogramma Species

以柞蚕卵繁殖的螟黄赤眼蜂和松毛虫赤眼蜂为研究对象,通过成虫死亡率、补充营养、蜂龄、逐日产卵量4个方面作了生殖特性的比较研究,并对产卵器结构进行解剖。结果表明,两种赤眼蜂在产卵特性上存在明显差异;产卵器结构差异极显著,松毛虫赤眼蜂产卵器长度为228±21.07μm,螟黄赤眼蜂为168±35.17μm。

Reproduction characters of Trichogramma dendrolimi and T.chilonis were compared from four aspects,including adult mortality rate,the number of egg-laying,complementary nutrients and age.Ovipositor structure was researched in the same time.The results showed that the reproduction characters of T.dendrolimi were different from T.chilonis.The ovipositor length of T.chilonis（228±21.07μm） was significantly higher than T.chilonis（168±35.17μm）.
