利用性诱剂法连续5年对黑河地区大豆食心虫的成虫羽化期进行调查,并采用生物防治、化学防治、生物与化学防治相结合的综合措施对大豆食心虫进行防控。2013年采取综合防控措施效果最好,防控效果达到84.4%。生物防治对大豆食心虫的防控效果相对稳定,可有效降低虫食率,防治效果达到71.28%。因此,在生产中应根据实际情况采用适宜的防控措施,以降低大豆食心虫虫食率,提高大豆产量和品质。
By using sex lure method for 5 consecutive years to investigate the eclosion period of soybean borer in Heihe area and to prevent and control the soya bean worm by comprehensive measures of biological control, chemical control, biological and chemical control. In 2013, the comprehensive prevention and control measures were the best and the prevention and control effect reached 84.4%. Biological prevention and control of soybean pod borer is relatively stable and effective control, which can effectively reduce the insecticidal rate, control effect reached 71.28%. Therefore, in the production should be based on the actual situation of the use of appropriate control measures to reduce the soybean meal heartworm insecticide feed rate and improve soybean yield and quality.
