This study updates the diversity, distribution, and seasonal trends of mosquitoes in a western region of Spain, assesses ecological determinants of Culex pipiens s.l., and determines form composition of Cx. pipiens s.s.
A total of 1,495 mosquitoes of 16 species was collected during 2012-2013, of which Cx. pipiens s.l. and Cx. theileri were the most abundant. Five new records for An. maculipennis s.s., Orthopodomyia pulcripalpis, Aedes (Ochlerotatus) punctor, Cx. europaeus, and Cx. modestus were found for this region. Cx. pipiens density varied across weather and habitat patterns, correlating positively with high temperatures and with a preference for urbanized areas and rural areas within a proximity of ovine farms. Moreover, molecular identification by CQ11FL was performed in 467 Cx. pipiens s.s., detecting both pipiens (66%) and molestus (8.4%) forms coexisting in different habitats (urban, peri-urban and rural) aboveground with a high degree of hybridization (25.7%). The abundance of Cx. pipiens in urban areas and farms, with the presence of hybrids, may increase their capacity to act as bridge vectors for the transmission of arboviral infections. These data will be helpful for further implementation of entomological programs focused on risk assessment for arboviruses or other mosquito-borne pathogens.
本研究更新了西班牙西部地区蚊子的多样性、分布和季节性趋势,评估了致倦库蚊复合组的生态决定因素,并确定了致倦库蚊指名亚种的形态组成。
2012 - 2013年期间共收集到16种1495只蚊子,其中致倦库蚊复合组和泰勒库蚊最为常见。该地区发现了淡色库蚊指名亚种、美丽直脚蚊、刺扰伊蚊、欧洲库蚊和温和库蚊的五个新记录。致倦库蚊密度随天气和栖息地模式而变化,与高温呈正相关,且偏好城市化地区以及靠近养羊场的农村地区。此外,对467只致倦库蚊指名亚种进行了CQ11FL分子鉴定,检测到致倦型(66%)和骚扰型(8.4%)在不同栖息地(城市、城郊和农村)的地面上共存,且杂交程度较高(25.7%)。城市地区和农场中致倦库蚊的大量存在以及杂交种的出现,可能会增加它们作为虫媒病毒感染传播桥梁媒介的能力。这些数据将有助于进一步实施侧重于虫媒病毒或其他蚊媒病原体风险评估的昆虫学计划。
