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.

蚊子翅膀的碰撞:喙库蚊、白纹伊蚊和埃及伊蚊之间的幼虫种间竞争揭示了共同生境中复杂的种群动态。
全球化、气候变化和国际贸易是白纹伊蚊(双翅目:Culicidae)和埃及伊蚊向新地区扩散的因素。在新入侵的栖息地,这些非本地物种可能成为虫媒病毒疾病的传播媒介,或增加疾病蔓延的风险。这些蚊子不断出现在新的地区,它们已经或将要与其他常驻蚊子物种的活动范围重叠。这项研究调查了入侵伊蚊如何与图尔基耶的本地库蚊竞争,这可能会影响整个蚊子种群动态和疾病传播风险。两种伊蚊在与喙库蚊的种间竞争中表现出截然不同的反应。白纹伊蚊主要是在食物丰富的较大容器中出现率较低,而埃及伊蚊则在所有食物条件下的混合培养中出人意料地茁壮成长。在与白纹伊蚊的竞争中,琵线蝇成虫的出现率下降了一半,而在与埃及伊蚊的特定条件下,琵线蝇成虫的出现率也下降了一半。竞争对不同物种和生命阶段的蚊子体型的影响不同。喙库蚊雌蚊在与埃及伊蚊竞争时体型变大,这可能表明资源优势或补偿策略。然而,白纹伊蚊的体型则表现出更细微的反应,这表明存在着复杂的相互作用。了解入侵蚊子和本地蚊子如何相互作用,可以让人们了解它们如何适应和共存于共同的栖息地。这些知识可以为有效的控制策略提供依据。这项研究强调了入侵伊蚊物种的不同反应,以及根据它们与本地喙蚊的竞争性相互作用来管理种群的潜力。该研究有助于改进对入侵蚊子传播及相关疾病风险的监测和预测系统。

期刊介绍: Medical and Veterinary Entomology is the leading periodical in its field. The Journal covers the biology and control of insects, ticks, mites and other arthropods of medical and veterinary importance. The main strengths of the Journal lie in the fields of: -epidemiology and transmission of vector-borne pathogens changes in vector distribution that have impact on the pathogen transmission- arthropod behaviour and ecology- novel, field evaluated, approaches to biological and chemical control methods- host arthropod interactions. Please note that we do not consider submissions in forensic entomology.
