目前森林害虫化学防治的特点有二:一、以短效和更有选择性的化合物或制剂代替广谱的长效杀虫剂;二、发展行为化学药剂(又称“确定剂”)以减少杀虫剂在森林中的应用。上述特点的产生是因为:一、对环境保护的注意不断增长;二、制定了限制或禁止使用某些化学药剂的法规;三、在森林生态系中大规模使用化学药剂的后果不能令人满意。
At present, there are two characteristics of chemical control of forest pests: one is to replace the broad-spectrum insecticide with short-acting and more selective compounds or preparations; and the second is to develop behavioral chemical agents (also called “determinators”) to reduce Application of insecticides in the forest. The above characteristics are due to the following reasons: First, the increasing attention to environmental protection; Second, the development of laws and regulations that restrict or prohibit the use of certain chemicals; Third, the consequences of large-scale use of chemical agents in forest ecosystems are unsatisfactory .
