| 摘 要： | 螟卵啮小蜂是水稻三化螟重要的卵寄生蜂,其幼虫还能取食三化螟的卵粒。为了充分利用这种有效天敌控制三化螟,我们在水稻生态系统中试验种植荸荠,用以繁殖荸荠白螟,荸荠白螟的卵作为螟卵啮小蜂的桥梁寄主。本文研究了新生态系统中荸荠白螟的年消长动态和“桥梁作用”以及它的生物学特性。

| Abstract: | Tetrastichus schoenobii is an important egg. parasite of yellow rice borer, Tryporyza incertulas. Larvae of the parasite prey on eggs of the rice borer. In order to enhance the suppressing effect of this parasite against the rice borer, water chestnut (Eleocharis tuberosa) , an aquatic food plant, was introduced into the rice paddy ecosystem. As a consequence, eggs of a water chestnut pest Scirpophaga praelata, served as the alternate "bridging host" for the parasite. This paper deals with some important biological characteristics, population fluctuation and the "bridging" function of S. praelata |
