| 入侵植物的繁殖特征是决定其能否成功入侵的关键，昆虫的访花行为会影响植物的繁殖成功率。为探究入侵植物在繁殖方面的入侵机制，于2022年3-11月对福州10种入侵植物的访花昆虫进行观测，记录访花昆虫的物种、数量、访花次数及停留时间，计算访花昆虫群落的物种多样性指数，并构建植物—访花昆虫网络。结果表明：（1）10种入侵植物共有访花昆虫6目34科66种，双翅目拥有较高的物种多样性且访花停留时间最长，膜翅目的访花频率最高且访问次数最多；（2）植物—访花昆虫网络显示，部分入侵植物与访花昆虫之间有较强互相的依赖性，访花网络存在明显的嵌套结构，网络结构稳定；（3）入侵植物能够在入侵地获取多种访花昆虫资源，并建立较为稳定的互作关系。植物与访花昆虫的互作关系是外来植物的入侵机制之一，为防止外来入侵植物利用入侵地传粉资源进一步入侵，建议在植物开花前将其清除。 |

| The reproductive characteristics of invasive plants are crucial determinants of their successful invasion, and the flower-visiting behavior of insects affects the reproductive success rate of plants. In order to explore the invasion mechanism of invasive plants in terms of reproduction, flower-visiting insects of 10 invasive plants in Fuzhou were observed from March to November 2022. The species, quantity, visitation frequency and residence time of flower-visiting insects were recorded, and the species diversity indices of flower-visiting insect communities were calculated, a plant-insect visitor network was constructed as well. The results showed that (1) the 10 invasive plants attracted a total of 66 species of flower-visiting insects from 6 orders, 34 families, among which Diptera had a high species diversity and longest residence time, while Hymenoptera visited flowers with the highest frequency and the most frequent visits. (2) The plant- insect visitor network revealed that there was a strong mutual dependence between certain invasive plants and flower-visiting insects, and there was an obvious nested structure indicating network stability. (3) The results further indicated that invasive plants could obtain a variety of flower-visiting insect resources in the invasion area and establish a relatively stable interaction relationship. The interaction between plants and flower-visiting insects is one of the invasion mechanisms of alien plants. To prevent further invasions by invasive alien plants by local pollination resources, we recommend removing plants before flowering. |
