| 摘要: |
| 提出一新的衡量害虫存活率指标“累积存活率”，该指标不仅能反映害虫在不同作物品种上存活率的动态变化特征，而且将虫态结构及其危害特征纳入其中，能反映出害虫在不同作物品种上的持续危害特征。具体应用该指标，分析了麦长管蚜在5个小麦品种上的累积存活率动态变化情况，为品种的抗蚜性综合决策分析提供了因素指标。 |

| New Index for Insect Accumulated Survival Rate and Its Application |
|
|
| Abstract: |
| The insect accumulated survival rate, a new index of insect survival, is
proposed in this paper.This new index can not only tell the dynamic change able course
of insect survival in various crop varieties, but also contains the age structure and
changeable characteristics of insect, as well as the continuous changeable feature of insect in vairous crop varieties.As it is applied, the dynamic changeable course of accumulated aphid survival rate of english grain aphid Macrosiphum avenae (Fab. ) in 5 wheat
varieties is studied in this paper. The new index could work as an integrated decisionmaking policy for aphid resistance in crop varieties. |
