Abstract

In Argentina, the distribution of Aedes albopictus (Skuse) is limited to two provinces with a subtropical climate and few records. This study aims to describe and compare assemblies of Culicidae that breed in artificial containers in two areas with different degrees of urbanisation where Ae. albopictus is present and to evaluate possible biotic interactions. We sampled container larval habitats of an urban (Eldorado city) and a rural environment (Colonia Aurora village). We performed generalized linear mixed models to evaluate which variables (containers characteristics or environment) are associated with the presence and abundance of Ae. albopictus, Aedes aegypti Linneaus and Culex quinquefasciatus Say, and the presence of mosquito predators (Lutzia bigoti (Bellardi) and Toxorhynchites spp.). Also, the relationship between the most abundant species was quantified in each environment using Hurlbert's C8 association coefficient. Ae. aegypti was the most abundant species in the urban environment, while Cx. quinquefasciatus and Ae. albopictus were the most abundant in the rural area. Predators were more present in the rural environment and affected the abundance of Aedes mosquitoes. Regarding the C8 index, Ae. aegypti was negatively associated with Ae. albopictus in the urban area, whereas in the rural area these species presented a significantly positive relationship. These results show that in urban environments the high abundance of Ae. aegypti could be affecting the Asian tiger mosquito as evidenced by local studies of food larval competition. Also a greater presence of predators could be affecting Ae. albopictus in rural environments.

阿根廷人工容器库蚊种群分布及对白纹伊蚊(双翅目:库蚊科)可能的生物相互作用
在阿根廷,白纹伊蚊的分布仅限于两个亚热带气候的省份,记录很少。本研究旨在描述和比较白纹伊蚊存在的两个城市化程度不同的地区在人工容器中繁殖的库蚊科的群落,并评估可能的生物相互作用。我们对城市(埃尔多拉多市)和农村环境(Colonia Aurora村)的集装箱幼虫栖息地进行了采样。我们使用广义线性混合模型来评估哪些变量(容器特征或环境)与白纹伊蚊、埃及伊蚊和致倦库蚊Say的存在和丰度以及蚊子捕食者(Lutzia biagii(Bellardi)和Toxorhychites spp.)的存在有关。此外,使用Hurlbert的C8关联系数对每个环境中最丰富的物种之间的关系进行量化。埃及伊蚊是城市环境中数量最多的物种,而致倦伊蚊和白纹伊蚊在农村地区数量最多。捕食者更多地出现在农村环境中,影响了伊蚊的数量。关于C8指数,埃及伊蚊在城市地区与白纹伊蚊呈负相关,而在农村地区,这些物种呈显著的正相关。这些结果表明,在城市环境中,埃及伊蚊的高丰度可能会影响亚洲虎蚊,当地对食物幼虫竞争的研究证明了这一点。此外,捕食者的大量存在可能会影响农村环境中的白纹伊蚊。

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.
