<p><i>Leishmania</i> spp. are zoonotic parasites transmitted by phlebotomine sand flies, including those of the <i>Lutzomyia</i> genus, which can cause leishmaniases in both humans and dogs. <i>Lutzomyia</i> spp. are established in many countries in South and Central America and some areas of the southern United States, with suspected potential of these vectors to undergo further range expansion due to climate change. A scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extensions for Scoping Reviews (PRISMA-ScR) guidelines to describe the current state of knowledge on the key ecological factors associated with <i>Lutzomyia</i> spp. survival, reproduction and establishment. The following electronic databases were searched for eligible studies published from 1 January 1990, to the date of search, 26 April 2023: CAB Direct (CABI), MEDLINE (via Ovid), Biological Sciences Database and Environmental Sciences Database. Primary research articles that were available in English and focused on ecological factors associated with <i>Lutzomyia</i> spp., such as climatic and habitat factors, geographic range, seasonality and temporality, and host abundance, were eligible for inclusion in the study. Following de-duplication, a total of 167 studies were included in Level 1 screening, 64 studies were included in Level 2 screening and 31 studies met the criteria for data extraction. Study locations included Argentina, Brazil, Colombia, Peru, Venezuela, the United States, Mexico and Canada, with some studies including multiple regions. A total of 31 different <i>Lutzomyia</i> spp. were assessed across these studies, with most (51.6%) of the studies focused on <i>Lutzomyia longipalpis.</i> Eligible studies investigated factors such as seasonality (<i>n</i> = 5), temperature (<i>n</i> = 19), precipitation (<i>n</i> = 13), humidity (<i>n</i> = 2), vegetation presence or requirements (<i>n</i> = 13), ecotypes (<i>n</i> = 7), and/or community type (i.e., urban, suburban, rural) (<i>n</i> = 5). <i>Lutzomyia</i> spp. activity was found to be higher during the rainy season, and peak when temperatures were between 20 and 25°C. <i>Lutzomyia</i> spp. were also found to preferentially reside in tropical or subtropical forests, which are characterised by their lack of a distinct dry season and high precipitation. This scoping review summarised the current state of the literature on the ecological factors associated with the survival, activity and reproduction of <i>Lutzomyia</i> spp. While there appears to be some consensus in the literature regarding some ecological requirements (such as seasonality, temperature and habitat features), overall, there is a lack of published research in this topic.

利什曼原虫是由噬血沙蝇(包括 Lutzomyia 属沙蝇)传播的人畜共患寄生虫,可导致人类和狗患利什曼病。Lutzomyia spp.已在南美洲和中美洲的许多国家以及美国南部的一些地区定居,由于气候变化,怀疑这些病媒的分布范围有可能进一步扩大。我们按照《系统综述和元分析扩展优选报告项目》(PRISMA-ScR)指南进行了一次范围界定综述,以描述与 Lutzomyia spp.生存、繁殖和建立相关的关键生态因素的知识现状。在以下电子数据库中搜索了 1990 年 1 月 1 日至 2023 年 4 月 26 日发表的符合条件的研究:CAB Direct (CABI)、MEDLINE(通过 Ovid)、生物科学数据库和环境科学数据库。以英文发表的主要研究文章均可纳入本研究,这些文章侧重于与 Lutzomyia 相关的生态因素,如气候和栖息地因素、地理范围、季节性和时间性以及寄主丰度。经过去重后,共有 167 项研究被纳入一级筛选,64 项研究被纳入二级筛选,31 项研究符合数据提取标准。研究地点包括阿根廷、巴西、哥伦比亚、秘鲁、委内瑞拉、美国、墨西哥和加拿大,部分研究涉及多个地区。这些研究共评估了 31 种不同的 Lutzomyia 属种,其中大部分(51.6%)研究的重点是 Lutzomyia longipalpis。符合条件的研究调查了季节性(5 项)、温度(19 项)、降水(13 项)、湿度(2 项)、植被存在或要求(13 项)、生态类型(7 项)和/或群落类型(即城市、郊区、农村)(5 项)等因素。研究发现,雨季时 Lutzomyia spp.的活性较高,气温在 20-25°C 之间时达到峰值。研究还发现 Lutzomyia spp.喜欢栖息在热带或亚热带森林中,这些森林的特点是没有明显的旱季,降水量大。虽然文献中似乎对某些生态要求(如季节性、温度和栖息地特征)达成了一些共识,但总体而言,该主题的公开研究还很缺乏。这给未来的研究带来了巨大挑战,因为未来的研究旨在预测在气候和土地利用变化的背景下 Lutzomyia spp.鉴于 Lutzomyia 与人类和动物健康的相关性,迫切需要对 Lutzomyia 进行更多的生态学研究。

Several species of ectoparasites, including chewing lice and mites are closely associated with their hosts. The Andean condor (Vultur gryphus) is globally listed as vulnerable by the IUCN and its population has been steadily declining in recent decades suggesting a potential extinction of associated entomofauna. The purpose of this study was to record the species of ectoparasites infesting three individuals of Andean condor found dead in the ‘Páramo del Almorzadero’ Santander Department, Northeastern Colombia. One juvenile (male) and two adults (male and female) Andean condors received for necropsy were carefully examined for ectoparasite infestation. Specimens were collected and preserved in ethanol (70%) for taxonomic studies. Morphologic identification and morphometric records were made under light microscopy. Some specimens were also prepared for scanning electron microscopy and others were subjected to DNA extraction to amplify and obtain sequences of the cytochrome-C oxidase subunit I (COI) gene for phylogenetic analyses. Lice were collected from the juvenile condor and the adult female and identified as Falcolipeurus assesor (Phthiraptera: Ischnocera) in the juvenile condor (8 females, 19 males and 8 nymphs) and the adult (1 female); Colpocephalum trichosum (Phthiraptera: Amblycera) in the juvenile (19 females, 24 males and 1 nymph) and the adult (2 females, 2 males and 3 nymphs); and Cuculiphilus zonatus (Phthiraptera: Amblycera) in the juvenile (40 females, 43 males and 15 nymphs) and the adult (1 male and 2 nymphs). Moreover, one mite collected from the juvenile condor was identified as Ancyralges cathartinus (Acari: Astigmata) (1 female). Morphometric data was obtained for the adult stages of F. assesor (6 females and 13 males), C. trichosum (9 females and 9 males) and C. zonatus (10 females and 10 males). We obtained the first DNA sequences of COI for F. assessor, and C. trichosum, where phylogenetic tree analysis showed that F. assessor is more closely related to Falcolipeurus marginalis, and C. trichosum to Colpocephalum kelloggi. This represents the first record of parasites in Andean condor from Colombia and contributes to the knowledge of chewing lice and mites associated with an endemic and endangered bird species. Further studies on Andean condor ectoparasites should be focused on documenting host–parasite interactions and potential health impacts in these wild birds.

包括咀嚼虱和螨虫在内的几种体外寄生虫与宿主密切相关。安第斯秃鹫(Vultur gryphus)被世界自然保护联盟(IUCN)列为全球易危物种,近几十年来其数量持续下降,这表明与之相关的体内寄生虫可能会灭绝。本研究的目的是记录在哥伦比亚东北部桑坦德省 "Páramo del Almorzadero "发现的三只安第斯秃鹫尸体上寄生的外寄生虫种类。对接收的一只幼年(雄性)和两只成年(雄性和雌性)安第斯秃鹰的尸体进行了仔细的外寄生虫侵扰检查。采集的标本保存在乙醇(70%)中,用于分类研究。在光学显微镜下进行形态鉴定和形态计量记录。部分标本还准备用于扫描电子显微镜,其他标本则进行了 DNA 提取,以扩增并获得细胞色素-C 氧化酶亚单位 I(COI)基因的序列,用于系统发育分析。从秃鹰幼鸟和成年雌鸟身上采集的虱子被鉴定为秃鹰幼鸟(8 只雌鸟、19 只雄鸟和 8 只若虫)和成年雌鸟(1 只雌鸟)身上的 Falcolipeurus assesor(Phthiraptera: Ischnocera);秃鹰幼鸟身上的 Colpocephalum trichosum(Phthiraptera:Cuculiphiluszonatus(Phthiraptera:Amblycera),幼鸟(19 只雌鸟、24 只雄鸟和 1 只若虫)和成鸟(2 只雌鸟、2 只雄鸟和 3 只若虫);以及 Cuculiphilus zonatus(Phthiraptera:Amblycera),幼鸟(40 只雌鸟、43 只雄鸟和 15 只若虫)和成鸟(1 只雄鸟和 2 只若虫)。此外,从秃鹰幼鸟身上采集到的一只螨虫被鉴定为 Ancyralges cathartinus(Acari:Astigmata)(1 只雌螨)。我们获得了 F. assesor(6 只雌螨和 13 只雄螨)、C. trichosum(9 只雌螨和 9 只雄螨)和 C. zonatus(10 只雌螨和 10 只雄螨)的成螨形态数据。我们首次获得了 F. assessor 和 C. trichosum 的 COI DNA 序列,系统发生树分析表明 F. assessor 与 Falcolipeurus marginalis 的亲缘关系更近,而 C. trichosum 与 Colpocephalum kelloggi 的亲缘关系更近。这是哥伦比亚首次记录安第斯秃鹰体内的寄生虫,有助于了解与这种特有的濒危鸟类相关的嚼虱和螨虫。对安第斯秃鹰体外寄生虫的进一步研究应侧重于记录宿主与寄生虫之间的相互作用以及对这些野生鸟类健康的潜在影响。

Mosquito traps, historically used for surveillance and research, have gained prominence as a tool for mosquito control, amidst concern over the environmental impact and increased resistance to insecticide-based methods. In this study, we tested the effectiveness of a mass trapping barrier design with two types of traps, Mosquito Magnet (MM) traps and BG-Protector (BGP) traps. This experiment was conducted in three coastal camping areas in southern France between summer and autumn 2022, where the presence of floodwater mosquito species with anthropophilic preferences like Aedes caspius represents a year-long nuisance. MM traps were set around the campsite as a barrier to interfere with mosquitoes from entering the campsites, whereas BGP traps were set within the campsites, with the aim of diverting mosquitoes away from humans at peak activity hours. Over 210,000 mosquitoes of 11 species from 4 genera were collected by both trap types across treatment campsites, with no significant differences in mosquito community samplings between BGP and MM traps. Barrier traps effectively targeted Ae. caspius, reducing total mosquito abundance in two of the three study sites by 34% and 55%. This study provides valuable insights into the efficacy and feasibility of using mass trapping barriers as a complementary control strategy for mosquito species in wetlands.

蚊子诱捕器历来用于监测和研究,但随着对环境影响的担忧以及对杀虫剂方法的抗药性的增加,它作为一种蚊子控制工具的地位日益突出。在这项研究中,我们用两种类型的诱捕器,即蚊子磁铁(MM)诱捕器和 BG-保护器(BGP)诱捕器,测试了大规模诱捕屏障设计的有效性。该实验于 2022 年夏季至秋季在法国南部的三个沿海露营区进行,在这些露营区,像卡皮伊蚊这样具有嗜人偏好的洪水蚊种常年滋扰。MM诱捕器设置在露营地周围,作为干扰蚊子进入露营地的屏障,而BGP诱捕器则设置在露营地内,目的是在活动高峰期将蚊子从人类身边引开。两种类型的诱捕器都在处理过的营地收集到了 4 个属 11 个种的 21 万多只蚊子,BGP 和 MM 型诱捕器在蚊子群落采样方面没有显著差异。阻隔性诱捕器有效地针对了食蚁兽,使三个研究地点中两个地点的蚊子总数量分别减少了 34% 和 55%。这项研究为使用大规模障碍物诱捕器作为湿地蚊虫物种的辅助控制策略的有效性和可行性提供了宝贵的见解。

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.

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。

Co-invasion, characterized by the simultaneous introduction of hosts and parasites with the latter establishing themselves in native hosts, is a phenomenon of ecological concern. Rattus rattus, a notorious invasive species, has driven the extinction and displacement of numerous avian and mammalian species and serves as a key vector for diseases affecting both humans and wildlife. Among the parasites hosted by R. rattus are fleas, which exhibit obligate parasitic behaviour, a generalist nature and high prevalence, increasing the likelihood of flea invasion. Simultaneously, invasive species can serve as hosts for native parasites, leading to potential amplification or dilution of parasite populations in the environment. In Chile, R. rattus has been present since the 17th century because of the arrival of the Spanish colonizers through the ports and has spread throughout urban, rural and wild Chilean territories. This study aims to evaluate whether co-invasion of native fleas of invasive rats occurs on native rodents in Chile and to determine whether black rats have acquired flea native to Chile during their invasion. For this, we captured 1132 rodents from 26 localities (20° S–53° S). Rattus rattus was found coexisting with 11 native rodent species and two species of introduced rodents. Among the native rodents, Abrothrix olivacea and Oligoryzomys longicaudatus exhibited more extensive sympatry with R. rattus. We identified 14 flea species associated with R. rattus, of which only three were native to rats: Xenopsylla cheopis, Leptopsylla segnis and Nosopsyllus fasciatus. These three species presented a higher parasite load in black rats compared to native fleas. Leptopsylla segnis and N. fasciatus were also found associated with native rodent species that cohabit with R. rattus. The remaining species associated with R. rattus were fleas of native rodents, although they were less abundant compared to those associated with native rodents, except for Neotyphloceras pardinasi and Sphinctopsylla ares. Although there has been evidence of flea transmission from rats to native species, the prevalence and abundance were relatively low. Therefore, it cannot be definitively concluded that these fleas have established themselves in native rodent populations, and hence, they cannot be classified as invasive fleas. This study underscores R. rattus’ adaptability to diverse environmental and geographical conditions in Chile, including its capacity to acquire fleas from native rodents. This aspect has critical implications for public health, potentially facilitating the spread of pathogens across various habitats where these rats are found.

共同入侵的特点是同时引入宿主和寄生虫,后者在本地宿主中建立自己的地位,这是一个令人担忧的生态现象。鼠类是一种臭名昭著的入侵物种,它已导致许多鸟类和哺乳动物物种灭绝和迁移,并成为影响人类和野生动物疾病的主要媒介。鼠蚤寄生的寄生虫中包括跳蚤,它们表现出强制性寄生行为、通性和高流行率,增加了跳蚤入侵的可能性。同时,入侵物种可以作为本地寄生虫的宿主,导致环境中寄生虫种群的潜在扩大或稀释。在智利,由于西班牙殖民者通过港口抵达,鼠蚤自 17 世纪以来就一直存在,并已遍布智利的城市、农村和野生区域。本研究旨在评估入侵鼠的本地跳蚤是否同时入侵智利本地啮齿动物,并确定黑鼠在入侵过程中是否获得了智利本地跳蚤。为此,我们从 26 个地点(南纬 20 度-53 度)捕获了 1132 只啮齿动物。结果发现,黑鼠与 11 种本地啮齿动物和 2 种外来啮齿动物共存。在本地啮齿动物中,Abrothrix olivacea和Oligoryzomys longicaudatus与Rattus有更广泛的共生关系。我们发现了 14 种与鼠类相关的跳蚤,其中只有 3 种是鼠类的原生跳蚤:Xenopsylla cheopis、Leptopsylla segnis 和 Nosopsyllus fasciatus。与本地跳蚤相比,这三种跳蚤在黑鼠体内的寄生虫量更大。还发现 Leptopsylla segnis 和 N. fasciatus 与与 R. rattus 共存的本地啮齿动物物种有关。除了 Neotyphloceras pardinasi 和 Sphinctopsylla ares 外,其余与 R. rattus 相关的物种都是本地啮齿类动物的跳蚤,但与本地啮齿类动物相关的跳蚤数量较少。虽然有证据表明跳蚤从老鼠传播到本地物种,但其流行率和数量都相对较低。因此,还不能明确断定这些跳蚤已经在本地啮齿动物种群中建立了自己的地位,因此不能将它们归类为入侵跳蚤。这项研究强调了鼠蚤对智利各种环境和地理条件的适应能力,包括从本地啮齿动物身上获取跳蚤的能力。这对公共卫生具有重要影响,可能会促进病原体在这些老鼠出没的不同栖息地传播。

Model forecasts of the spatiotemporal occurrence dynamics of diseases are necessary and can help understand and thus manage future disease outbreaks. In our study, we used ecological niche modelling to assess the impact of climate on the vector suitability for bluetongue disease, a disease affecting livestock production with important economic consequences. Specifically, we investigated the relationship between the occurrence of bluetongue outbreaks and the environmental suitability of each of the four vector species studied. We found that the main vector for bluetongue disease, Culicoides imicola, a typically tropical and subtropical species, was a strong predictor for disease outbreak occurrence in a region of southern Portugal from 2004 to 2021. The results highlight the importance of understanding the climatic factors that might influence vector presence to help manage infectious disease impacts. When diseases impact economically relevant species, the impacts go beyond mortality and have important economic consequences.

对疾病的时空发生动态进行模型预测很有必要,这有助于了解并进而管理未来的疾病爆发。在我们的研究中,我们使用生态位建模来评估气候对蓝舌病病媒适宜性的影响,蓝舌病是一种影响畜牧业生产并造成重要经济后果的疾病。具体来说,我们调查了蓝舌病爆发与所研究的四种病媒的环境适宜性之间的关系。我们发现,蓝舌病的主要传播媒介 Culicoides imicola(一种典型的热带和亚热带物种)是 2004 年至 2021 年葡萄牙南部地区蓝舌病爆发发生的有力预测因素。这些结果凸显了了解可能影响病媒存在的气候因素的重要性,有助于管理传染病的影响。当疾病影响到经济上相关的物种时,其影响不仅仅是死亡率,还会产生重要的经济后果。

<p>This study explores the influence of small dams on the exposure to malaria vectors during the dry season in Kasungu district, Malawi, an area recently identified as high priority for malaria interventions by the National Malaria Control Programme. Small dam impoundments provide communities with a continuous supply of water for domestic and agricultural activities across sub-Saharan Africa and are considered vital to food security and climate change resilience. However, these permanent water bodies also create ideal breeding sites for mosquitoes in typically arid landscapes. The study focuses on a specific dam impoundment and its vicinity, aiming to assess its spatial and temporal influence on indoor vector densities. From May to August 2021, CDC light traps were used to measure indoor mosquito densities for two consecutive nights per month in three communities located at increasing distances from the dam (0, ~1 and ~2 km). Simultaneously, drone imagery was captured for each community, enabling the identification of additional standing water within approximately 400 m of selected households. Larval sampling was carried out within the impoundment periphery and in additional water bodies identified in the drone imagery. Generalised linear mixed models (GLMMs) were employed to analyse the indoor <i>Anopheles</i> abundance data, estimating the effects of household structure (open/closed eaves), month, temperature and water proximity on malaria vector exposure. Throughout 685 trapping nights, a total of 1256 mosquitoes were captured, with 33% (412) being female <i>Anopheles</i>. Among these, 91% were morphologically identified as <i>Anopheles funestus</i> s.l., and 5% as <i>Anopheles gambiae</i> s.l. Catches progressively decline in each consecutive trapping month as the environment became drier. This decline was much slower in Malangano, the community next to the dam, with abundance being notably higher in June and July. Further, the majority of <i>An. gambiae</i> s.l. were caught in May, with none identified in July and August. <i>Anopheles</i> larvae were found both in the impoundment and other smaller water bodies such as irrigation wells in each survey month; however, the presence of these smaller water bodies did not have a significant impact on adult female mosquito catches in the GLMM. The study concludes that proximity to the dam impoundment was the primary driver of differences between survey communities with the abundance in Chikhombwe (~1 km away) and Chiponde (~2 km away) being 0.35 (95% confidence interval [CI], 0.19–0.66) and 0.28 (95% CI, 0.16–0.47) lower than Malangano, respectively, after adjusting for other factors. These findings underscore the importance of targeted interventions, such as larval source management or housing improvements, near small dams to mitigate malaria transmission risks during the dry season. Further research is needed to develop cost-effective strategies for vector control within and around these impoundme
本研究探讨了小型水坝对马拉维卡松古区旱季疟疾病媒暴露的影响,该地区最近被国家疟疾控制计划确定为疟疾干预的高度优先地区。小型水坝蓄水池为撒哈拉以南非洲地区的社区提供了持续的生活和农业用水,被认为对粮食安全和抵御气候变化至关重要。然而,在典型的干旱地区,这些永久性水体也是蚊子理想的繁殖地。这项研究的重点是一个特定的水坝蓄水池及其附近地区,旨在评估其对室内病媒密度的时空影响。从 2021 年 5 月到 8 月,在距离大坝越来越远(0、~1 和 ~2 公里)的三个社区,使用 CDC 灯光诱捕器每月连续两个晚上测量室内蚊子密度。同时,每个社区都拍摄了无人机图像,从而确定了所选住户约 400 米范围内的其他积水。幼虫采样在蓄水池周边和无人机图像中确定的其他水体中进行。采用广义线性混合模型(GLMMs)分析室内按蚊丰度数据,估计家庭结构(开放式/封闭式屋檐)、月份、温度和水域距离对疟疾病媒暴露的影响。在 685 个诱捕夜中,共捕获了 1256 只蚊子,其中雌性按蚊占 33%(412 只)。随着环境变得更加干燥,捕获量在每个连续的诱捕月逐渐下降。在大坝附近的马兰加诺社区,这种下降速度要慢得多,6 月和 7 月的捕获量明显较高。此外,大多数冈比亚疟蚊都是在 5 月份捕获的,7 月和 8 月没有发现任何冈比亚疟蚊。在每个调查月,在蓄水池和其他较小的水体(如灌溉井)中都发现了按蚊幼虫;但是,在 GLMM 中,这些较小水体的存在对成年雌蚊的捕获量没有显著影响。研究得出结论,靠近水坝蓄水池是造成调查社区之间差异的主要原因,在调整其他因素后,Chikhombwe(约 1 公里远)和 Chiponde(约 2 公里远)的丰度分别比 Malangano 低 0.35(95% 置信区间 [CI],0.19-0.66)和 0.28(95% 置信区间,0.16-0.47)。这些发现强调了在小水坝附近采取有针对性的干预措施(如幼虫源管理或住房改善)以降低旱季疟疾传播风险的重要性。需要进一步开展研究,以制定具有成本效益的病媒控制策略,控制这些蓄水池内部和周围的病媒。

Influence of egg density on larval development and adult body size of cat fleas (Ctenocephalides felis) 卵密度对猫跳蚤(Ctenocephalides felis)幼虫发育和成虫体型的影响。

Fleas (Siphonaptera) are holometabolous insects with larval and adult stages that exhibit vastly different ecologies from each other. Adult fleas are parasitic and feed exclusively on the blood of a vertebrate host, whereas flea larvae do not live on hosts and consume dried faecal blood from adult fleas. Because flea larvae rely on adult flea faeces for food, excrement and eggs must fall in the same location; thus, larval density is likely high in these restricted habitats. However, the influence of larval density on the subsequent adult stage has not been examined. In the present study, we utilized egg density to investigate density-dependent effects on larval development and adult body size in the cat flea (Ctenocephalides felis Bouché) (Siphonaptera: Pulicidae). Specifically, eggs were collected to create three different larval densities (n = 50, 100 and 150 per 56.7 cm2), and hatched larvae from all groups were fed an excess amount of adult faecal pellets. Larval development was measured by recording the proportion of eggs that developed to the pupal stage and the proportion of eggs that reached adulthood (eclosion). The body size of eclosed adults was quantified for both sexes using head length and length of the total body. We found that the number of eggs had no effect on the proportion of larvae that pupated or the proportion of larvae that eclosed; however, higher egg densities resulted in larger body sizes for both sexes. Overall, these data yield significant insight into how the ecology of larval fleas impacts the biology of the resultant adults.

跳蚤(虹吸目)是一种全代谢昆虫,其幼虫和成虫阶段的生态环境大相径庭。跳蚤成虫是寄生虫,专门吸食脊椎动物宿主的血液,而跳蚤幼虫则不寄生在宿主身上,而是吸食成蚤的干粪血。由于跳蚤幼虫以成蚤粪便为食,排泄物和卵必须落在同一地点;因此,在这些受限的栖息地,幼虫密度可能很高。然而,幼虫密度对后续成虫阶段的影响尚未得到研究。在本研究中,我们利用卵的密度来研究密度对猫跳蚤(Ctenocephalides felis Bouché)(虹彩科:Pulicidae)幼虫发育和成虫体型的影响。具体来说,收集卵以产生三种不同的幼虫密度(n = 50、100 和 150 颗/56.7 平方厘米),并给各组孵出的幼虫喂食过量的成虫粪粒。通过记录发育到蛹期的卵的比例和发育到成虫(羽化)的卵的比例来测量幼虫的发育情况。雌雄成虫的体型是通过头长和体长来量化的。我们发现,卵的数量对幼虫化蛹的比例和幼虫羽化的比例没有影响;但是,卵的密度越高,雌雄幼虫的体型越大。总之,这些数据有助于我们深入了解幼虫跳蚤的生态如何影响成虫的生物学特性。
{"title":"Influence of egg density on larval development and adult body size of cat fleas (Ctenocephalides felis)","authors":"Piper N. Zellner,&nbsp;Lisa D. Brown","doi":"10.1111/mve.12735","DOIUrl":"10.1111/mve.12735","url":null,"abstract":"<p>Fleas (Siphonaptera) are holometabolous insects with larval and adult stages that exhibit vastly different ecologies from each other. Adult fleas are parasitic and feed exclusively on the blood of a vertebrate host, whereas flea larvae do not live on hosts and consume dried faecal blood from adult fleas. Because flea larvae rely on adult flea faeces for food, excrement and eggs must fall in the same location; thus, larval density is likely high in these restricted habitats. However, the influence of larval density on the subsequent adult stage has not been examined. In the present study, we utilized egg density to investigate density-dependent effects on larval development and adult body size in the cat flea (<i>Ctenocephalides felis</i> Bouché) (Siphonaptera: Pulicidae). Specifically, eggs were collected to create three different larval densities (<i>n</i> = 50, 100 and 150 per 56.7 cm<sup>2</sup>), and hatched larvae from all groups were fed an excess amount of adult faecal pellets. Larval development was measured by recording the proportion of eggs that developed to the pupal stage and the proportion of eggs that reached adulthood (eclosion). The body size of eclosed adults was quantified for both sexes using head length and length of the total body. We found that the number of eggs had no effect on the proportion of larvae that pupated or the proportion of larvae that eclosed; however, higher egg densities resulted in larger body sizes for both sexes. Overall, these data yield significant insight into how the ecology of larval fleas impacts the biology of the resultant adults.</p>","PeriodicalId":18350,"journal":{"name":"Medical and Veterinary Entomology","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141317618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
