30个芒果品种对芒果切叶象甲雌成虫抗性评价

在田间自然诱发条件下，研究30个芒果品种对芒果切叶象甲雌成虫的抗性。结果表明，澳大利亚11号、澳大利亚14号、澳大利亚8号、澳大利亚12号、澳大利亚9号、红芒6号、青皮和海南土芒等8个品种为抗虫品种；澳大利亚7号、金煌、秋芒、澳大利亚10号、云南小芒、爱文、红象牙、四季芒、澳大利亚16号、金白花、澳大利亚15号、椰香、紫花、贵妃、海顿、粤西1号、泰国生吃芒、留香、台农1号、托米等20个品种为轻感品种；三年芒、白象牙2个品种为中感品种。研究结果可为芒果抗虫品种的选育和对该虫的防治提供科学依据。

Evaluation of mango varieties for resistance against female adults of Deporaus marginatus Pascoe

Thirty mango varieties were evaluated for resistance to adult females of Deporaus marginatus Pascoe by natural infection under field conditions in West Hainan. The results showed that 8 varieties, viz., Australia 11, Australia 14, Australia 8, Australia 12, Australia 9, Zill, Okyong and Hainantumang, were insect-resistant varieties; 20 varieties, viz., Australia 7, Chiin huang, Neelum, Australia 10, Yunnanxiaomang, Irwin, Red ivory, Sijimang, Australia 16, Jin white flower, Australia 15, Dashehari Aman, Zihua mango, Guifei, Haden, Yuexi 1, Thailand Shengchimang, Liuxiang, Tainong 1 and Tommy, were moderately insect-resistant, while Sanniamang and White ivory were found to be intermediately sensitive to the insect. Our studies will provide the basis for breeding insect-resistant mango varieties and will help in control of Deporaus marginatus Pascoe in mango fields.
