进行大面积荒漠蝗虫的化学防治涉及各种景观区和生态系统,在环境敏感地区或其周边地区,农药喷撒没有严格的限制,作业者往往忽视这些地区的敏感性。人们对荒漠蝗虫控制所带来的环境问题的关注程度与日俱增,因而有必要制定明确的指导性防治原则。本文旨在确定和描绘非洲东北部对杀虫剂污染特别敏感的区域,如保护区、湿地、人口居住区、绿洲,以及候鸟集中分布的地区,这些区域与1986~1998年间实际进行的荒漠蝗虫防治区域相对比。结果表明,环境脆弱地区,特别是湿地,如临时性水域和红树林,以及人类居住区附近都进行过化学防治,而且一定程度上还涉及到保护区和候鸟大量聚集区。
Chemical control of large areas of desert locusts involves a wide range of landscapes and ecosystems. There is no strict restriction on pesticide spraying in environmentally sensitive areas or surrounding areas, and operators often ignore the sensitivity of these areas. The increasing concern about the environmental problems caused by the control of desert locusts makes it necessary to establish a clear guiding principle for prevention and control. This article aims to identify and characterize areas of northeastern Africa that are particularly sensitive to pesticide contamination, such as protected areas, wetlands, populated areas, oases, and areas where migratory birds are concentrated, in line with the desert locusts actually carried out between 1986 and 1998 Control area relative ratio. The results show that chemical control is provided in environmentally vulnerable areas, particularly in wetlands such as temporary waters and mangroves, and in the vicinity of human settlements, and to a degree also associated with the high concentration of protected areas and migratory birds.
