However, new trap models that use LED lights might provide a more cost-effective alternative. This study compared the efficacy of a modified commercial Katchy light trap with two CDC light trap models in capturing sand flies in the Amazonian rainforest of Peru. Using a 3 x 3 randomized Latin square design, the light traps were compared based on phlebotomine sand fly species total abundance, species richness, sex-specific collections, and efficiency in capturing potential vector species. A total of 1,184 sand flies were collected, representing nine genera and 25 species, including three species that had not been previously reported in the Cusco department. Significant differences in sand fly collections based on trap type were found, with the modified Katchy light trap capturing significantly higher total abundance and species richness compared to CDC light traps. This pattern held for both female and male sand flies, with the modified Katchy trap also collecting more potential vector species in terms of both abundance and species richness, although differences in potential vector species richness were only significant compared to the incandescent CDC light trap. These results suggest that the modified Katchy trap is a viable, cost-effective alternative for sand fly surveillance, offering potential improvements in leishmaniasis vector monitoring.","PeriodicalId":56065,"journal":{"name":"Journal of Vector Ecology","volume":"50 1","pages":"60-68"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602368","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}

The association of climatic and environmental factors with the spatiotemporal distribution of species in relation to vegetation cover and human proximity was examined. Twelve geo-referenced ovitraps were randomly installed in each park, covering areas with varying degrees of vegetation and human activity from September, 2018 to February, 2020, during three weeks each season. A total of 57,604 Aedes aegypti or Aedes albopictus eggs were collected, identifying 10,228 Ae. aegypti and 23,764 Ae. albopictus larvae. Seasonal variations showed distinct patterns with higher mosquito abundances during warmer and rainier seasons. The association between abundance and climatic factors was more evident at the level of the aedini assemblies than at the level of the local populations. Aedes aegypti was predominantly found in peripheral and transitional areas with higher human activity during rainy and warmer seasons. In contrast, Ae. albopictus thrived in inner park areas with greater vegetation cover and lower human activity during drier and milder seasons. The abundance of Ae. aegypti and Ae. albopictus was influenced by climatic factors and park-specific microhabitats. These findings underscore the importance of targeted vector control strategies in urban park settings during seasons favorable for mosquito reproduction. Understanding the interaction between ecological factors and these mosquitoes in urban environments is critical for effective public health interventions.","PeriodicalId":56065,"journal":{"name":"Journal of Vector Ecology","volume":"50 1","pages":"48-59"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602373","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}

These areas have experienced extreme weather events, including wildfire, drought, and heavy rainfall, which have changed the environment. Questing ticks were collected over nine months, identified to species, and screened for tick-borne pathogens using qPCR. Four hundred and fifty-nine ticks were collected, including 54 adults from SCC and 405 from SKY, consisting of 279 (68.9%) larvae, 2 (0.5%) nymphs, and 124 (30.6%) adults. At SCC, Ixodes pacificus and Dermacentor occidentalis accounted for 92.6% (50/54) and 7.4% (4/54), respectively.

These findings were corroborated by generalized linear mixed models, which highlighted location-specific effects and seasonal variations in physicochemical parameters associated with oviposition. Our study also explored polarized light as a potential oviposition cue. While a direct causal link between polarized light patterns and oviposition requires further investigation, a positive correlation between pH levels and circularly polarized light patterns suggests a potential interaction between water chemistry and this optical cue.

The Great Plains region of the United States is experiencing a biome-level change as grasslands are being converted to forests through the process of woody plant encroachment by eastern redcedar (ERC). There is a need to evaluate how mosquitoes respond to fine scale habitat characteristics within areas experiencing ERC encroachment. This study examined the influence of fine-scale vegetation differences on mosquito abundance, bloodmeal hosts, and infection with West Nile virus (WNV) in eight ERC-encroached sites across Oklahoma. Mosquito traps were placed in three unique habitats in ERC-encroached sites. Ae. albopictus, Ae. vexans, An. punctipennis, Cx. erraticus, and Cx. tarsalis were most abundant in the ecotone and/or forested areas of ERC trees compared with grass. Ps. columbiae was more abundant in grassland than in forest. Blood meal analysis indicated that mosquitoes fed primarily on mammals, and we detected Anaplasma species in several blood meals. These results suggest that important mosquito vectors may occur throughout much of ERC-encroached areas, a finding that has consequences for blood meal acquisition, pathogen transmission, and thus public health and land management programs throughout the Great Plains.","PeriodicalId":56065,"journal":{"name":"Journal of Vector Ecology","volume":"50 1","pages":"100-110"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602372","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}

Results suggest MPs are commonly found in artificial containers and tires, and at higher concentrations than natural sites. Furthermore, MPs found in all potential oviposition sites were predominantly fragments and fibers. SEM analysis revealed diverse morphologies and indicated potential microbial colonization on MP surfaces.
