摘要: 针对长江中游棉区棉花多虫复合危害问题,设计了6种害虫4种组合的复合危害系统。运用通径分析方法,定量描述了多种害虫对棉花的侵害及其间的互作效应。通过多种害虫对棉花产量和品级的直接影响效应和间接影响效应分析,认为当多虫复合危害时,害虫间的相互作用就其对作物的侵害而言,表现为增强效应和减弱效应。在此基础上,研究并制定了“两红”(棉红铃虫和朱砂叶螨)复合危害动态防治指标,经验证、示范及推广应用,取得了显着的经济、生态和社会效益。

Abstract: To counter the compound damage by multi-pests in the cotton-producing area of central Yangtze River banks, a compound damage system of six species of pests with three combinations was designed.The damage of multi-pests on cotton and their interactive effect were quantitatively described by path analysis.The analysis for direct and indirect effects of multi-pests on cotton yield and its quality indicated that the interaction of pests on the damage of cotton plants was positive or negative.On the basis of these, the dynamic control indicators of compound damage for two red pests (Pectinophora gossypiella and Tetranychus cinnabarinus) were formulated, which were demonstrated to have notable economic, ecological and social benefits by experiment and expansion.
