1农业防治合理轮作应合理轮作,避免重茬。增加虫源地中耕次数,特别是在化蛹和羽化期增加铲耥,可减少成虫羽化,减轻危害。选用抗虫或耐虫品种大豆对食心虫的抗性表现在两方面。一是回避成虫产卵,二是使入荚幼虫死亡率高。在应用中应因地制宜,选用虫食率低、丰产性好的品种。合理密植适当增加单位面 A reasonable rotation of agricultural control should be reasonable rotation, to avoid heavy cropping. Increasing the number of cultivation in the source of insects, especially in the pupation and eclosion increased scoop, can reduce adult emergence, reduce the harm. Selection of insect-resistant or insect-resistant varieties of soybean resistance to moth worms in two ways. First, to avoid adult eggs, the second is to make pod larvae mortality. In the application should be adapted to local conditions, the choice of insect-feeding rate is low, high yield good varieties. Reasonable close planting appropriate increase unit surface
