| 摘 要： | 作者系统研究了１２个油菜品种对３种油菜蚜虫的抗性动态，结果表明３种蚜虫在各品种上的累积存活率、平均发育历期和产仔动态均有明显差异；同时建立了品种抗性对３种蚜虫种群增长的干扰效应模型，分析了各品种的耐害补偿功能及自然感蚜特性。特别是本文提出的“累积存活率”指标，不仅能反映出品种抗性的动态变化过程，而且将种群的年龄结构与为害特性纳入其中，在衡量品种的抗虫性程度中更具有普遍的应用价值。

| Abstract: | The resistance dynamics of twelve rape varieties to three rape aphids were systematically studied, the results showed that there were obvious differences among the accumulated survivals, mean developmental duration and reproductive dynamics of various aphid X variety combinations. The disturbance effect models of resistance of varieties to population dynamics of aphids were established, and the tolerant and compensatory functions of different varieties were analyzed. It was indicated that, the "accumulated survival index" proposed in this paper is not only capable to reflect the developments of resistance of varieties, but also the age structures and damage characters of aphid populations. Therefore, this index is more practicable to determine the resistance of varieties to rape aphids than the old index. |
