在生物共同进化过程中,生物的分泌物、代谢物等化学因子是生物间相互作用必不可少的控制因素。从自然界中发掘这些现象,弄清其化学本质并进一步查明其作用机理的研究称之为化学生态学。在化学生态学研究的基础上,以干扰昆虫、微生物特有生理机能为目标探索农药活性物质是新型农药开发的途径之一(深海浩1986)。杀虫剂-抗保幼激素的研究被称为第四代农药。在杀菌剂领域,围绕植物病原菌毒素的研究受到重视。植物病原菌毒素,特别是寄主特异性毒素(Host specific toxin)在病害发生发展过程中具有重要的作用。采用化学的方法中和毒素消除其有害作用或抑制毒素产生,必然干扰病原菌的致病过程,从而达到防治植物病害的目的。
In the process of biological co-evolution, biological secretions, metabolites and other chemical factors are essential biological interactions between the control factor. From nature to explore these phenomena, to clarify its chemical nature and to further clarify its mechanism of action called chemical ecology. Based on the study of chemical ecology, it is one of the ways to explore new types of pesticides with the objective of interfering with the specific physiological functions of insects and microorganisms (Shen Haihao 1986). Pesticides - Anti-juvenile hormone research is called the fourth generation of pesticides. In the field of fungicides, attention has been given to the study of phyto-pathogenic toxins. Plant pathogenic toxins, especially host specific toxin, play an important role in the development of the disease. The use of chemical methods and toxins to eliminate their harmful effects or inhibit the production of toxins, will inevitably interfere with pathogenic process of pathogens, so as to achieve the purpose of controlling plant diseases.
