长期研究与实践证实,抗虫品种在相同虫口下比其它品种具有优质高产的能力,对害虫的控制能在较长时期内起作用,是害虫综合治理的基础。大豆对大豆蚜的抗性(耐害性)差异优为突出,耐害品种不防治也可获得较高产量。目前用化学药剂防治大豆蚜,费用大,污染环境,蚜虫抗药性问题愈加突出。大豆蚜还是大豆花叶病毒的主要传播媒介,目前尚无有效的杀病毒剂。传统的方法很难控制病毒危
Long-term research and practice have confirmed that insect-resistant varieties have the ability of high-quality and high-yielding than other varieties under the same insect population, and the control of pests can work for a long period of time, which is the basis of comprehensive pest management. Soybean aphid the resistance (tolerance) difference is particularly prominent, resistant varieties can not control the higher yield can be obtained. Currently using chemical agents to control soybean aphid, costly, polluting the environment, the problem of aphid resistance become more prominent. Soybean aphid or soybean mosaic virus is the main media, there is no effective viricides. The traditional method is difficult to control the virus
