Abstract

The Amblyomma cajennense (Fabricius) complex (Acari: Ixodidae) is represented by six species of hard ticks widely distributed from southern Texas in the United States to northern Argentina. Species within the complex feed on a variety of vertebrate hosts, primarily mammals, including humans. These ticks are the main vector of the bacterium Rickettsia rickettsii (Brumpt; Rickettsiales: Rickettsiaceae) and have been associated with the transmission of several arboviruses. In Colombia, one of the most ecologically diverse countries of the Neotropics, two species of the complex have been recorded with sympatric distribution in the northwestern part of the country: Amblyomma mixtum (Koch) and Amblyomma patinoi (Labruna, Nava & Beati). The latter is of medical importance as it has been confirmed as a competent vector of R. rickettsii in inter-Andean valleys of Colombia. Here, we assessed the current distribution of A. patinoi and predicted changes in its distribution over the century under different climate change scenarios. Additionally, we incorporated new records, delved deeper into the distribution of A. patinoi and interpreted model results using the climate classification and ecoregions for the Neotropical region. The results showed the presence of A. patinoi in 79 localities distributed across 34 municipalities and seven departments of the Caribbean and Andean regions of Colombia. In addition, new records were identified in two additional departments (Valle del Cauca and Caquetá) of the Andean and Amazon regions, as well as additional records in the department of Cundinamarca, especially in the inter-Andean Magdalena River basin. A. patinoi has been recorded in five ecoregions (Cauca Valley Dry Forests, Guajira-Barranquilla Moist Forests, Magdalena Valley Dry Forests and Magdalena-Urabá Moist Forests) and is associated with horses, cattle, dogs and humans. Its elevational range extends from 8 to 645 m a.s.l. in the Caribbean region and from 497 to 1712 m a.s.l. in the Andean region and inter-Andean valleys. The potential distribution models suggest that A. patinoi presents high climatic suitability in the Caribbean areas and inter-Andean valleys. Under climate change scenarios a possible expansion of the species distribution is observed in areas currently not recorded in the Neotropics, in countries such as Brazil, Peru and Venezuela. However, geographical conditions, such as elevation, could limit its distribution at higher elevations.

新热带硬蜱patinoi Amblyomma的现状和潜在分布(蜱目:蜱科)。
camjenense Amblyomma (Fabricius) complex(蜱螨亚纲:伊蚊科)以6种硬蜱为代表,广泛分布于美国德克萨斯州南部至阿根廷北部。复杂的物种以各种脊椎动物为宿主,主要是哺乳动物,包括人类。这些蜱是细菌立克次体(Brumpt;立克次体:立克次体科),并与几种虫媒病毒的传播有关。哥伦比亚是新热带地区生态多样性最丰富的国家之一,在该国西北部已记录到两种共地分布的复合物种:Amblyomma mixtum (Koch)和Amblyomma patinoi (Labruna, Nava & Beati)。后者在医学上具有重要意义,因为它已被确认为哥伦比亚安第斯山脉山谷间立克次体的一种有能力的媒介。在此基础上,我们评估了不同气候变化情景下黄花蒿的分布现状,并预测了其百年来的分布变化。此外,我们还纳入了新的记录,深入研究了黄花蒿的分布,并利用气候分类和新热带地区的生态区域对模式结果进行了解释。结果表明,在哥伦比亚加勒比海和安第斯地区的34个市和7个省的79个地区存在着帕蒂诺伊虫。此外,在安第斯和亚马逊地区的另外两个省(考卡谷和卡奎特)以及在昆迪纳马卡省,特别是在安第斯山脉间的马格达莱纳河流域发现了新的记录。在五个生态区域(考卡谷干燥森林、瓜吉拉-巴兰基亚潮湿森林、马格达莱纳谷干燥森林和马格达莱纳-乌拉布潮湿森林)都有记录,与马、牛、狗和人类有关。它的海拔范围从8米到645米不等。在加勒比区域和从公元497年至1712年。在安第斯地区和安第斯山谷之间。潜在的分布模式表明,黄花蒿在加勒比海地区和安第斯山脉间山谷具有较高的气候适宜性。在气候变化情景下,在巴西、秘鲁和委内瑞拉等新热带地区目前没有记录的地区,观察到物种分布可能扩大。然而,地理条件,如海拔,可能限制其在高海拔地区的分布。

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.
