防治大豆食心虫方法的研究

试验结果表明,采用下列防治方法,可以有效控制大豆食心虫的危害.(1)应用性诱剂诱杀大豆食心虫雄蛾,可以降低大豆虫食率43%.(2)释放螟黄赤眼蜂寄生大豆食心虫卵,可以降低大豆虫食率46%-69%.(3)释放辐射不育大豆食心虫雄蛾干扰交配,可以降低大豆虫食率87%.将上述方法用于大豆食心虫的综合防治,减少化学杀虫剂的使用,保护天敌,并逐渐增加天敌数量,压低大豆食心虫虫口密度,达到生态调控的目的.

METHODS FOR CONTROLLING SOYBEAN MOTH (Leguminirola glycinioorella)

Experiment results showed that the below methods were effective to control soybean moth ,they were,(1) applying sex attractant lured them,which coald reduce seeds dameged by an insect pests of 43%.(2) releaseing Trichogramma chilonis reduced that of 46%-69%. (3) releaseing sterile soybean male moth irradiated by 6 0Co-r disturbed mating,which could reduce that of 87%. Those interated pest managemets could reduce the amout of chemical,protect natural enemy,and decrease soybean moth population.In the end,the gole to control soybean moth by ecological method could be reached.
