Abstract: Fifty-two rice varieties resistant to whitebacked planthopper (WBPH) which were identified by standard seedbox screening technique (SSST) and field screening were tested for antixenosis (nonpreference) and 22 for antibiosis level. The results showed that varieties of Yunnan (China), such as Hao-Nuo-Liang, Bai-Nuo, Gui-Yi-Gu, Dian-Rui 337-68 et al. have higher level of antixenosis for humph feed, adult settle and oviposition N22. Leng-Shui-Gu(681), Jiao-Lu, Fa-Pao- Gu, Zhe-Li 1 have higher level of antibiosis for WBPH population growth, numph survival and honeydew excreted.

摘要： 利用经苗期和田间抗性鉴定对白背飞虱(Sogatella furcifera)具有中抗水平以上的国内外品种52个进行拒性和22个品种进行抗生性测定。结果表明,对若虫取食、成虫定居和产卵的拒性以云南品种的毫糯亮、白糯、鬼衣谷、滇瑞337～68等较为明显。抗生性(种群增长、若虫生存率、排泄量)测定结果表明:N22、冷水谷(681)、脚鲁、法炮谷、浙丽1号等5个品种抗生性明显。
