摘　　要：研究了4个不同类型水稻品种(中早39、中浙优8号、秀水134和甬优12)对稻纵卷叶螟生长发育和产卵量的影响。取食中早39、中浙优8号、秀水134和甬优12四个不同类型的水稻,对稻纵卷叶螟的幼虫发育历期和存活率无显著影响;取食中早39的稻纵卷叶螟的蛹历期最短,仅9.6 d;在秀水134取食后的稻纵卷叶螟蛹最轻(12.45 mg),羽化后的雌成虫产卵量最低,为34.1粒/雌。综合来看,在供试的4个类型的水稻品种中,与杂交籼稻中浙优8号和籼粳杂交稻甬优12相比,粳稻品种秀水134不利于稻纵卷叶螟的种群发展。The growth and development,fecundity of rice leaffolder（RLF）,Cnaphalocrocis medinalis,feeding on four different rice varieties were studied. The results showed that the larvae and pupal duration of RLF were not affected by feeding on four tested rice varieties plants. The pupal duration of RFL feeding on Zhongzao 39 was 9. 6 d which is shortest. The lightest pupal weight（12. 45 mg/individual）and the lowest fecundity（34. 1 eggs/female） of RFL was found on Xiushui 134. In a comprehensive view,Xiushui 134,the japonica rice variety,is more adverse to the growth of RFL population in four tested rice varieties.
