飞蝗具有异地迁飞、集中和选择产卵地的习性,对于此种虫害的根除问题,显然不能单独依靠治的办法来解决。中国科学院昆虫研究所蝗虫工作组在总结蝗虫猖獗规律与各地农、林、水利等建设的关系后,于1954年提出了“改”、“治”结合的根除蝗害理论。“改”是因地制宜改造蝗区的自然面貌,以消灭适合蝗虫发生繁殖的环境条件;“治”是在蝗虫发生时采取各种有效措施,及时扑灭,以防止为害。根据上述理论,于1954年拟订了根治洪泽湖与微山湖的蝗灾方案,1958—1959年在山东省
Migratory locusts have the habit of relocating in different places and concentrating and choosing the place to lay their eggs. Obviously, the problem of eradication of such pests can not be solved by treating them alone. After concluding the relationship between the rampant locusts and the construction of agriculture, forestry and water conservancy, the locust working group of the Institute of Entomology of the Chinese Academy of Sciences put forward the theory of eradicating locusts by combining “reforming” and “governing” in 1954. “Change” is based on the local conditions to transform the natural beauty of the locust area in order to eliminate suitable for locusts reproduce the environmental conditions; “rule” is in the locust occurred when taking various effective measures to promptly extinguished to prevent harm. According to the above theory, a plan for locust mitigation of Hongze Lake and Weishan Lake was drafted in 1954, and in 1958-1959 in Shandong Province
