Invasive alien plants have a significant impact on biodiversity, crop and pasture production, human and animal health, water resources, and economic development. As most low- and middle-income countries do not have the resources to actively manage invasive plants, many have intentionally introduced biological control agents to help manage their most important weeds. Some of these introductions have resulted in the successful control of numerous weeds such as Chromolaena odorata, Mimosa diplotricha, Pistia stratiotes, and Salvinia molesta. These successes are partly due to the reliance on biological control agents that have been tested and utilized elsewhere. However, despite the successes in weed biological control to date, many low- and middle-income countries are reluctant to pursue weed biological control, due to poor perceptions of biological control and lack of capacity. This results in missed opportunities to manage many weeds cost-effectively, and in so doing, increasing production costs and a dependency on herbicides.

低收入和中等收入国家的杂草生物防治。
外来入侵植物对生物多样性,农作物和牧草生产,人类和动物健康,水资源以及经济发展具有重大影响。由于大多数中低收入国家没有资源来积极管理入侵植物,因此许多国家有意引入生物防治剂来帮助管理其最重要的杂草。这些引进中的一些已成功地控制了多种杂草,如臭铬菊(Chromolaena odorata),含羞草(Mimosa diplotricha),开心果(Pistia stratiotes)和鼠尾草(Salvinia molesta)。。这些成功部分归因于对已经在其他地方测试和利用的生物防治剂的依赖。然而,尽管迄今为止在杂草生物防治方面取得了成功,但由于对生物防治的认识较差且缺乏能力,许多中低收入国家仍不愿进行杂草生物防治。这导致失去了以经济有效的方式管理许多杂草的机会,从而增加了生产成本和对除草剂的依赖。
