Interactions between invasive species can have important consequences for the speed and impact of biological invasions. Containers occupied by the invasive mosquito, Aedes albopictus Skuse, may be sensitive to invasive plants whose leaves fall into this larval habitat. To examine the potential for interactions between invasive leaf species and larval A. albopictus, we conducted a field survey of leaf material found with A. albopictus in containers in Palm Beach County, Florida and measured density dependent responses of A. albopictus larvae to two invasive and one native leaf species in laboratory experiments. We found increased diversity of leaf species, particularly invasive species, in areas further from the urbanized coast, and a significant positive association between the presence of Schinus terebinthifolious (Brazilian pepper) and the abundance of A. albopictus. In laboratory experiments, we determined that larval growth and survivorship were significantly affected by both larval density and leaf species which, in turn, resulted in higher population performance on the most abundant invasive species (Brazilian pepper) relative to the most abundant native species, Quercus virginiana (live oak). These results suggest invasive leaf species can alleviate density dependent reductions in population performance in A. albopictus, and may contribute to its invasion success and potential to spread infectious disease.

入侵的叶子资源减轻了入侵蚊子白纹伊蚊的密度依赖性。

入侵物种之间的相互作用会对生物入侵的速度和影响产生重要影响。入侵蚊子 Aedes albopictus Skuse 占据的容器可能对叶子落入幼虫栖息地的入侵植物敏感。为了检查入侵叶种与幼虫 A. albopictus 之间相互作用的可能性，我们对在佛罗里达州棕榈滩县容器中发现的 A. albopictus 叶子材料进行了实地调查，并测量了 A. albopictus 幼虫对两种入侵物种的密度依赖性反应。和实验室实验中的一种本地叶种。我们发现，在远离城市化海岸的地区，叶种的多样性增加，尤其是入侵物种，Schinus terebinthifolious（巴西胡椒）的存在与 A. albopictus 的丰度之间存在显着的正相关。在实验室实验中，我们确定幼虫的生长和存活受到幼虫密度和叶种的显着影响，反过来，相对于最丰富的本地物种栎属，最丰富的入侵物种（巴西胡椒）的种群表现更高弗吉尼亚（活橡木）。这些结果表明，入侵的叶种可以缓解白纹松鼠种群密度依赖的减少，并可能有助于其入侵成功和传播传染病的潜力。我们确定幼虫的生长和存活率受到幼虫密度和叶种的显着影响，反过来，相对于最丰富的本地物种 Quercus virginiana（活橡树），最丰富的入侵物种（巴西胡椒）的种群表现更高）。这些结果表明，入侵的叶种可以缓解白纹松鼠种群密度依赖的减少，并可能有助于其入侵成功和传播传染病的潜力。我们确定幼虫的生长和存活率受到幼虫密度和叶种的显着影响，反过来，相对于最丰富的本地物种 Quercus virginiana（活橡树），最丰富的入侵物种（巴西胡椒）的种群表现更高）。这些结果表明，入侵的叶种可以缓解白纹松鼠种群密度依赖的减少，并可能有助于其入侵成功和传播传染病的潜力。
