In the global analysis, Canonical Variate Analysis (CVA) showed slight shape variation between individuals from the beginning to the peak activity. Pairwise cross-validated reclassification yielded an accuracy of 68% for the beginning and 72% for the peak of activity. At the beginning of the activity, morphometric distances among areas were significant, cross-validated classification showed an overall accuracy of 68.9%, and no association was found between geographic and shape distances. During the peak of activity, no significant differences in morphological distances among areas were detected for the Centre-North, East-Westand East-South comparison using both Mahalanobis and Procrustes distances or for West-South comparison using Procrustes distances. Classification accuracy was 49%, and a significant correlation between the geographic and shape distances was observed. The phenetic tree grouped all geographic areas from the peak activity. Both the overall and partial analyses indicated that the wing shape was more variable at the beginning compared with the peak activity, where greater shape homogeneity was observed. The thermal characteristics of a temperate climate may modulate the exchange of individuals among areas throughout the season, resulting in morphological variation. Differences in wing shapes among geographic areas and no correlation between the geographic and morphological distances at the beginning may suggest that the activity season of Ae. aegypti could originate from morphologically divergent local populations. During the peak activity, the similarity in wing shapes among the geographic areas may indicate an enhanced dispersal flow of individuals during the period of highest relative abundance, resulting in a phenotypic homogenization of the wing shape. Patterns of wing shape changes over a relatively short time period may reflect specific dynamics within the urban environment.</p>","PeriodicalId":18350,"journal":{"name":"Medical and Veterinary Entomology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167201","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}

Here, we tested the efficiency of artificially feeding mosquitoes Aedes aegypti versus the feeding on anaesthetised mouse in the laboratory. Moreover, we compared reproductive parameters of females fed on rabbit blood treated with three different anticoagulant methods (sodium citrate, heparin and defibrination) to select the best efficiency method. Our results show that artificial feeding was as attractive for females as the anaesthetised mouse, since no significant difference in the percentage of engorged females was found among methods. The average number of eggs laid per female was significantly lower when females fed on blood treated with the anticoagulant sodium citrate, while no difference was found among the other methods. Also, there was no significant difference among methods when egg viability was measured.

While overwintering species compositions have been documented in several parts of Europe, no comprehensive data exist for Estonia or for the Baltic region. This study aimed to investigate the species composition of diapausing female mosquitoes across natural and artificial overwintering sites in Estonia. Mosquitoes were collected during the winter season of 2023/2024 from 18 overwintering locations, including caves, bunkers and dugouts. Specimens were primarily identified morphologically, and species distribution patterns were analysed across sites. However, a subset of the Culex pipiens/Culex torrentium from the Piusa cave system was additionally identified to species level using molecular methods to test the accuracy of morphological identification. The relative temperature and humidity of each collection site were also recorded. A total of 5268 mosquitoes were analysed, of which 5090 (96.6%) were identified as Cx. pipiens/Cx. torrentium. Culiseta annulata (2.0%) and Culex territans (1.3%) were the next most frequent taxa, while species from the Anopheles maculipennis complex and Culiseta alaskaensis were rarely encountered. Species abundance varied among sites, with some, such as Astangu and Tartu Kalmistu paljand, supporting multiple taxa, while some others were dominated exclusively by Cx. pipiens/Cx. torrentium. Further molecular analysis of 300 randomly chosen Cx. pipiens/Cx. torrentium revealed 3/4 of the specimens to be Cx. torrentium, contrasting with the preliminary morphological identification. The highest mosquito abundances were recorded at overwintering sites where temperatures at the time of sampling ranged between 5.3 and 7.5°C and relative humidity ranged between 58% and 70%. Our study provides the first comprehensive overview of overwintering mosquito populations in Estonia. Culex pipiens/Cx. torrentium were the dominant overwintering species across selected hibernation sites, highlighting their ecological adaptability and potential epidemiological importance. The presence of other species was limited and spatially restricted. Based on molecular analysis of a randomly selected subset of specimens from the Piusa cave system, Cx. torrentium may be more abundant than Cx. pipiens at some sites. Furthermore, morphological identification is not suitable for differentiating between the overwintering females of Cx. pipiens and Cx. torrentium. These findings highlight the importance of integrating molecular tools into overwintering mosquito surveys to improve epidemiological assessments.

Although fewer than 10% of the more than 3700 known mosquito species act as vectors, many thrive in cities due to climate, habitat availability and proximity to humans. Salta, northern Argentina, an understudied yet highly diverse region regarding mosquito fauna, is undergoing rapid urban growth. This study addresses a key gap by examining mosquito species developing in Salta's urban drainage channels. Understanding species composition in these settings is essential for guiding sustainable, targeted vector control, especially as urbanization and insecticide resistance alter transmission dynamics. Salta, the provincial capital, has experienced notable demographic expansion in recent decades. The city is intersected by drainage channels designed to manage rainwater and mitigate flooding. Fourteen sampling sites were selected across varied urban sectors, covering most of the channels and representing different channel conditions. Larvae and/or pupae were consistently found at over 80% of sites, and at least 10 mosquito species were identified across the genera Culex, Anopheles, Aedes and Lutzia, demonstrating the ecological significance of these habitats. Medically important species, including Culex quinquefasciatus and Aedes aegypti, were detected. The former was dominant across all seasons, with its abundance negatively correlated with pH and positively with water depth. These findings provide the first documentation of drainage channels as mosquito larval habitats in the region and show that urban drainage infrastructure can support diverse mosquito assemblages, including species with contrasting ecological requirements.
