药剂防治是害虫综合防治中的一个重要组成部份,但是长期不合理的施用,容易导致害虫产生抗药性,再增猖獗,残留污染,造成人畜中毒事故,影响环境质量,破坏生态平衡,早为世人关注。近十余年来,国际上对天然产物(包括杀虫植物)的研究,给予高度重视。人工合成拟除出菊酯的突破,为植物杀虫剂的广泛深入研究以及新型农药的研制与应用,指出了广阔的前景。自Gill等(1971)从楝科的
Prevention and control of pesticides is an important part of integrated pest management. However, long-term unreasonable application can easily lead to pest resistance and then rampant and residual pollution, causing human and animal poisoning accidents, affecting environmental quality and damaging ecological balance as early as World attention. In the recent ten years, the international community has paid great attention to the research of natural products (including insecticidal plants). Artificial synthesis to be removed from the pyrethrum breakthrough, extensive and in-depth study of plant pesticides and the development and application of new pesticides, pointed out broad prospects.
