大豆食心虫是我区大豆产区的主要害虫之一。幼虫蛀入豆荚食害豆粒。被害豆粒形成虫孔、碎辦,严重时整个豆粒被吃光,不仅影响大豆产量,而且降低大豆品质。近几年,由于放松对大豆食心虫的防治,虫食率有所上升。以阿鲁科尔沁旗为例,一般年份虫食率15—30%,严重发生时可达35—48%。全旗每年种植大豆10万亩左右,以每亩减产15斤计算,全旗每年约减产150万斤,造成的经济损失达60余万元。因此,应抓紧做好大豆食心虫的防治。科学研究和生产实践表明,防治大豆食心虫要贯彻:“预防为主,综合防治”,的植保方针,坚持以农
Soybean borer is one of the main pests in our soybean producing area. Larvae eaten pods eat beans. Damaged pest kernels form wormholes, broken up, and severely eaten throughout the pea kernels, affecting not only soybean yield but also soybean quality. In recent years, the insecticidal rate has risen due to the easing of the control of soybean borer. Take Aruqerqin Banner as an example, the general pest prevalence rate is 15-30% and in severe cases it can reach 35-48%. The entire annual planting of about 10 acres of soybean to 15 kg per acre production cut, the entire annual output of about 1.5 million kg, resulting in economic losses of 60 million. Therefore, we should pay close attention to soy bean worms prevention and treatment. Scientific research and production practices show that the prevention and control of soybean bee-moth should be implemented: the principle of “prevention first, comprehensive prevention and cure”, and the policy of plant protection
