为了摸清棉叶跳虫发生规律,为今后防治提供科学依据,鄱阳湖区病虫考察协作组,特搜集了鄱阳湖区沿岸产棉县历年棉叶跳虫调查资料及近年发生为害实况,结合外界因素,初步综合归纳分析简报如下:一棉叶跳虫是棉花主要害虫之一。解放初期,曾成为全省棉区的头号大害虫,每年都严重发生为害,减产籽棉达40~50%。1956年后,由于棉区普遍使用“1605”、“1059”、滴滴涕等有机磷和有机氯农药,对此虫打击得力,发生为害受到了控制。除个别年份局部棉区出现较重发生为害外,每年均属轻发或中等偏轻发生,发生为害面积仅在5%左
In order to find out the regularity of cotton leaf hopper and provide a scientific basis for future prevention and treatment, the survey team of pest and disease investigation in Poyang Lake area collected the investigation data of cotton leaf hoppers in Shimian County of Poyang Lake area in recent years and the actual situation of damage in recent years. Combining the external factors Preliminary summary report is summarized as follows: A Cotton leaf hopper is one of the major cotton pests. In the early days of the liberation, it became the number one pest in the cotton area of the whole province, causing severe damage every year and reducing the output of seed cotton by 40-50%. After 1956, due to widespread use of “1605”, “1059” and other organic phosphorus and organochlorine pesticides such as DDT in the cotton area, the pest was hit hard and the damage was brought under control. Except for the occurrence of serious damage in some cotton areas in a few years, they are either light-weight or moderately-weighted each year, with an area of only 5%
