在生态环境和食品遭受化学农药污染愈发严重的今天,生物防治在有害生物综合治理中的地位和作用越来越重要。而作为生物防治的最直接有效手段的生物源农药的开发及使用也越来越引起人们的重视。生物源农药包括植物源、动物源和微生物源农药。植物源农药是指从植物内提取的具有杀虫、杀菌物质的天然物质。植物农药在整个农药中将占有一定地位,其中楝科楝属的一些种、芸香科柑橘属、胜红蓟属、番荔枝属、唇形科的毛茛属、透骨草属等具有良好的开发前景。动物源农药包括活体生物和原生动物。它是一种可再生的资源,在调节有害生物种群的同时,其自身的种群数量得到繁衍和增殖,与有害生物协调同步发展。微生物源农药由微生物本身及其代谢产物所构成。此类农药安全性高。目前开发应用的
Nowadays, the ecological environment and the increasingly serious contamination of foodstuffs by chemical pesticides are playing an increasingly important role in the integrated pest management. As the most direct and effective means of biological control of bio-pesticides development and use of more and more aroused people’s attention. Biogenic pesticides include plant, animal and microbial pesticides. Plant-sourced pesticides are natural substances with insecticidal and bactericidal substances extracted from plants. Plant pesticides in the entire pesticide will occupy a certain position, including Melia some species of Melia, Rutaceae citrus, red thistle, Annonaceae, Labiatae Ranunculus, Speranskiaceae have good development prospect. Animal-derived pesticides include living organisms and protozoa. It is a renewable resource that, while regulating pest populations, reproduces and multiplies its own population in parallel with the coordinated development of pests. Microbial pesticides consist of microorganisms themselves and their metabolites. Such pesticides are safe. Currently developed and applied
