七十年代末至八十年代初期本市不少地区槐尺蠖(Macaria elongaria Leech)为害严重.自1984年以来,由于各级有关领导重视防治,加强了各区和街道办事处的除虫力量,正确掌握防治策略(狠抓一、二代,重点挑治三、四代)、防治时机、喷药质量、消灭害虫于发源地以及合理用药等,槐尺蠖为害近年已得到稳定控制,喷药
In the late 1970s and early 1980s, Macaria elongaria Leech was severely damaged in many areas of the municipality. Since 1984, due to the emphasis placed on prevention and control by relevant leaders at all levels, the pest control power in districts and sub-district offices has been strengthened. In recent years, it has been steadily controlled by the prevention and control strategies (pay close attention to the first and second generations and the key to the third and fourth generations), prevention and control of the timing, quality of spraying, elimination of pests at the place of origin and rational drug use.
