Agriculture is dependent on insect pollination, yet in areas of intensive production agriculture, there is often a decline in plant and insect diversity. As native habitats and plants are replaced, often only the weeds or unwanted vegetation persist. This study compared insect diversity on mango, , a tropical fruit tree dependent on insect pollination, when weeds were present in cultivation versus when they were removed mechanically. The pollinating insects on both weeds and mango trees were examined as well as fruit set and yield in both the weed-free and weedy treatment in South Florida. There were significantly more pollinators and key pollinator families on the weedy mango trees, as well as significantly greater fruit yield in the weedy treatment compared to the weed-free treatment. Utilizing weeds, especially native species, as insectary plants can help ensure sufficient pollination of mango and increase biodiversity across crop monocropping systems.
农业依赖昆虫授粉，但在集约化生产农业地区，植物和昆虫的多样性往往会下降。随着原生栖息地和植物被取代，通常只有杂草或不受欢迎的植被留存下来。本研究比较了在种植芒果（一种依赖昆虫授粉的热带果树）时，有杂草存在与机械去除杂草两种情况下的昆虫多样性。对杂草和芒果树上的传粉昆虫进行了检查，并对南佛罗里达州无杂草处理和有杂草处理中的坐果率和产量进行了比较。与无杂草处理相比，有杂草的芒果树上的传粉者和关键传粉者家族显著更多，且有杂草处理中的果实产量也显著更高。利用杂草，尤其是本地物种作为诱虫植物，有助于确保芒果有足够的授粉，并增加整个单一作物种植系统的生物多样性。
