| 摘 要： | 在肉室人工接虫条件下研究大豆３个高抗品种吴江青豆３、通山薄皮黄豆甲、赶泰－２－和３个高感品种皖８２－１７８、山东大豆及Ｍｏｒｓｏｙ对斜纹夜蛾的抗性表现。结果表明，抗感材料间以叶面积损失率为指标的抗虫性差异极为，而对斜纹夜蛾产卵排趋性差异不显著。

| Abstract: | The resistance of six soybean varieties, namely, Wujiangqingdou-3, Tong-shanbopihuangdoujia and Gantai-2-2, the high resistant (HR) ones, and Wan82-178, Shandongdadou and Morsoy, the high susceptible (HS) ones, to cotton leafworm Pro-denia litura (Fabricius) was studied in solarium and under inoculaton condition. The results showed that there were significant differences between the leaf consumptions, but not the oviposition antixenosis, of this insect pest on HR and HS varieties. After P. litura larvae fed on HR varieties, the larval leaf consumption and body weights of larva and pupa decreased, the mortality/development duration of larva, but not of pupa, obviously increased/prolonged. Consequently, the resistance of soybean to P. litura is mainly antibiotic. |
