Abstract:
Globalisation, climate change and international trade are the factors contributing to the spread of Aedes albopictus (Diptera: Culicidae) and Ae. aegypti into new areas. In newly invaded habitats, these non-native species can serve as arbovirus disease vectors or increase the risk of disease spill over. These mosquitoes continue to emerge in new areas where they have or will have overlapping ranges with other resident mosquito species. The study investigates how invasive Aedes mosquitoes compete with the native Culex pipiens in Türkiye, which might affect the overall mosquito population dynamics and disease transmission risks. Both Aedes species exhibited contrasting responses to interspecific competition with Cx. pipiens. While Ae. albopictus suffers reduced emergence primarily in larger containers with abundant food, Ae. aegypti surprisingly thrives in mixed cultures under all food conditions. Adult Cx. pipiens emergence drops by half against Ae. albopictus and under specific conditions with Ae. aegypti. Competition influences mosquito size differently across species and life stages. Culex pipiens females grow larger when competing with Ae. aegypti, potentially indicating resource advantage or compensatory strategies. However, Ae. albopictus size shows more nuanced responses, suggesting complex interactions at play. Understanding how invasive and native mosquitoes interact with each other can provide insights into how they adapt and coexist in shared habitats. This knowledge can inform effective control strategies. The study highlights the differential responses of invasive Aedes species and the potential for managing populations based on their competitive interactions with the native Cx. pipiens. It can contribute to improved monitoring and prediction systems for the spread of invasive mosquitoes and the associated disease risks.
摘要:
全球化,气候变化和国际贸易是导致白纹伊蚊(Diptera:Culicidae)和Ae传播的因素。埃及伊蚊进入新的领域。在新入侵的栖息地,这些非本地物种可以充当虫媒病毒病载体或增加疾病蔓延的风险。这些蚊子继续出现在新的地区,它们已经或将与其他常驻蚊子物种有重叠的范围。该研究调查了入侵的伊蚊如何与蒂尔基耶的本地淡色库蚊竞争,这可能会影响整体蚊子种群动态和疾病传播风险。两种伊蚊对Cx的种间竞争表现出相反的反应。Pipiens.而Ae.白纹目主要在具有丰富食物的较大容器中减少出现,Ae.埃及伊蚊令人惊讶地在所有食物条件下的混合文化中蓬勃发展。成人CX.Pipiens的出现对Ae下降了一半。白纹和在特定条件下与Ae。埃及伊蚊.竞争在物种和生命阶段对蚊子大小的影响不同。与Ae竞争时,淡色库蚊雌性会长大。埃及伊蚊,可能表明资源优势或补偿性策略。然而,Ae.白纹目大小显示出更细微的反应,暗示着复杂的互动。了解侵入性和本地蚊子如何相互作用,可以提供有关它们如何适应和共存于共享栖息地的见解。这些知识可以为有效的控制策略提供信息。该研究强调了入侵伊蚊物种的不同反应以及基于它们与本地Cx的竞争性相互作用来管理种群的潜力。Pipiens.它可以有助于改进侵入性蚊子传播和相关疾病风险的监测和预测系统。
