一种新的人工合成性信息素为玉米虫害防治开辟了新途径。河北省张家口农业专科学校和江苏省激素研究所在有关部门协作下,利用性信息素防治亚洲一代玉米螟试验,取得了可喜成果。八五年十一月在张家口由省内外专家鉴定了这项科研成果。张家口农业专科学校和江苏省激素研究所从1983年开始至1985年,利用该所生产的合成玉米螟性信息素先后在涿鹿、遵化、容城、河间等十几个县的一万五千亩面积不同气候条件下试验,利用施放性信息素,使雄虫无法辨认雌虫方位、干扰雌雄正常交尾的“迷向法”和采用性信息素诱捕器捕杀大量雄虫,改变雌雄比例、减少交配机率的“诱杀法”,达到了减少种群发生量、减轻害虫的为害效果。试验表明:诱杀 A new synthetic pheromone has opened up a new way for corn pest control. Hebei Province Zhangjiakou Agricultural College and Jiangsu Province Institute of Hormones in collaboration with relevant departments, the use of sex pheromones against Asian corn borer test, and achieved gratifying results. In November 1985, Zhangjiakou experts from both inside and outside the province appraised the achievements of the scientific research. Zhangjiakou Agricultural College and Jiangsu Institute of Hormones from 1983 to 1985, the use of the production of synthetic corn borer sex pheromone successively in Zhuolu, Zunhua, Rongcheng, Hejian a dozen counties, such as 10,000 Five thousand acres of area under different climatic conditions, the test, the use of pheromone, the male insects can not identify the orientation, interferes with male and female normal mating “law” and the use of sex pheromone traps kill a large number of male and female to change the ratio , To reduce the chance of mate “trap kill”, to reduce the occurrence of the population, reduce pest damage. Test shows: trap kill
