日本黄脊蝗在我国北方从未造成过危害,1989年以来,在石家庄西部山区发生危害逐年加重,局部地区更是暴发成灾,已成为为害农作物的土蝗优势种,现将其综合防治技术介绍如下: 一、处理越冬寄主,降低成虫越冬成活率。日本黄脊蝗成虫80％以上,在向阳荒坡草地,枯枝落叶层内越冬,秋冬季结合积肥,组织农民打草砍柴,清除枯枝落叶,恶化成虫越冬生境,能有效的降低成虫越冬存活率,抑制翌年种群数量的增殖。据试验和大面积处理越冬寄主调查,可降 Japan Huangji locust in northern China has never caused any harm, since 1989, in the western mountainous area Shijiazhuang hazards have increased year by year, some areas even more outbreaks, has become the dominant species of locusts harm crops, now its comprehensive control technology Described as follows: First, the treatment of wintering host, reduce the survival rate of adult wintering. More than 80% of Japanese yellow ridge locust adult, overwintering in the sunny grassland, litter layer, combined with fertilizer in autumn and winter, organizing peasants to grass cutting firewood, clearing litter, worsening adult overwintering habitat, can effectively reduce adult overwintering Survival rate, inhibiting the proliferation of population numbers the following year. According to the test and large-scale treatment of winter host investigation, can be reduced
