近几年来在药剂防治大豆食心虫方面取得了一定的成绩。但由于防治食心虫期间,大豆生长繁茂,业已封垅,又遇雨季,给药剂防治带来了很大困难。为了降低防虫成本,增加收入,进行了大豆品种抗虫能力的鉴定,探明抗虫机制,给抗虫育种工作提供依据。我所近两年围绕大豆形态学、生态学、组织结构等方面对食心虫的反应及其原因进行了试验研究,现将结果整理如下: In recent years in the chemical control of soy bean worms have made some achievements. However, due to the control of mungbean during the lush growth of soybeans, has been sealed 又, in case of rainy season, to prevent pesticides brought great difficulties. In order to reduce pest control costs and increase income, identification of pest resistance of soybean varieties was carried out to find out the mechanism of pest-resistance and provide basis for insect-breeding work. In the past two years, I have conducted experimental research on the reaction and the reasons for mungbean insects in the aspects of soybean morphology, ecology, and organizational structure. The results are summarized as follows:
