日本黄脊蝗在我区西部山区发生危害日趋严重,局部地区暴发成灾,已成为影响石家庄地区西部山区大秋粮食作物产量的优势种之一。据调查,1989年平山县寨北乡、古月镇45个村1.7万亩玉米、谷子、大豆被害,一般减产10～15％,严重的减产高达30％以上甚至绝收。一般虫口密度在每平方米30～50头之间,最高达152头以上。由于虫口密度高,致使全县0.145万亩谷忝、玉米、豆类作物被蝗蝻吃成光杆,颗粒无收。西部山区其他各县也遭到不同程度的危害。为此,经过几年的调查研究和防治试验,搞清了该虫发生规律,找到了最佳防治办法。
Japan Huangji locust in the western mountainous areas in the increasingly serious damage, outbreaks in some areas, has become the impact of the western region of Shijiazhuang Daqiu grain crop yield one of the dominant species. According to a survey, in 1989, 17,000 mu of maize, millet and soybean in 45 villages in Zhabei Township and Guyue Town of Pingshan County were killed, 10-15% of them were generally cut, and serious cuts of up to 30% or even of the crops were scarce. Insect population density of 30 to 50 heads per square meter, up to 152 or more. Due to the high density of insect population, resulting in 0.145 million mu of the county valley, corn, beans crop is eating into the light pole by locust, grain crop failure. Other counties in western mountainous areas have also been endangered to varying degrees. To this end, after several years of investigation and research and prevention and control tests, figure out the law of occurrence of the pest and find the best way to prevent and control.
