However, due to reduced effectiveness and significant increase in resistance among Ae. taeniorhynchus (Wiedemann) (Insecta: Diptera: Culicidae) to methoprene products, the use of methoprene for mosquito control in the IRMCD ceased in 2009. Given the current limited availability of safe, effective and affordable larvicide products, discussions have emerged about the potential reintroduction of methoprene-based products for Ae. taeniorhynchus control in the IRMCD. To determine the feasibility of methoprene product reintroduction in the field control operations, laboratory bioassays were conducted to assess the resistance status of Ae. taeniorhynchus populations from field collections directly. These bioassays involved exposing late 4th instar larvae of Ae. taeniorhynchus to technical grade methoprene. The results revealed varying levels of resistance to methoprene among 16 field Ae. taeniorhynchus populations for the last 2 yr. Our findings confirm that methoprene resistance persists in some of the local Ae. taeniorhynchus populations. The outcomes of this research will assist IRMCD in strategic decision-making regarding the utilization of methoprene products for future Ae. taeniorhynchus control measures.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"604-609"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rain barrels are green infrastructure tools used to conserve rainwater for outdoor use, though they may also serve as a source of mosquito habitat in residential neighborhoods. To identify rain barrel features, maintenance habits, and other conditions associated with the presence of juvenile mosquitoes (ie month), we conducted periodic inspections of rain barrels at 53 households in central Illinois, USA between June and September 2016. Additionally, we administered a questionnaire to the household study participants. In the first month of the study, a diversity of mosquito species was detected in household rain barrels, but from July to September juveniles of Ae. albopictus were predominant. More than half of inspected households contained at least one mosquito-positive rain barrel within the study period. Using stepwise model selection, the strongest predictors of whether or not mosquito juveniles were detected in rain barrels were the use of a preventative measure (eg Bti, chlorine, goldfish), the presence of a mesh covering on the lid of the barrel, and the month of the year. Additionally, the participant questionnaire revealed that the majority of respondents were aware of immediate elimination methods, but few were aware of the need for long-term preventative maintenance of rain barrels against larval mosquito colonization. These findings provide valuable insight into best practices for mosquito prevention in green infrastructure and highlight the importance of proper maintenance and education to minimize juvenile mosquito habitat.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"545-551"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143473285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Hemiptera: Cimicidae), is a pervasive indoor pest with prominent medical, veterinary, and economic impacts. Bed bug infestations are controlled by a wide range of insecticides, including pyrethroids, neonicotinoids, pyrroles, and phenylpyrazoles; however, bed bugs have evolved resistance mechanisms to most of these insecticides. Mutations in the Rdl (resistance to dieldrin) gene, located in a subunit of the γ-amino butyric acid (GABA)-gated chloride channel, have been identified in several pest insects, including the German cockroach. These have been found to confer resistance to fipronil, a phenylpyrazole insecticide commonly used in urban environments, in addition to cyclodienes (eg dieldrin), a class of insecticides banned in most countries since the 1990s. While resistance to dieldrin and fipronil has been reported in bed bugs, both C. lectularius and the tropical bed bug, C. hemipterus, the occurrence of mutations in the Rdl gene has yet to be thoroughly investigated. In this study, we sequence a fragment of the Rdl gene commonly found to harbor cyclodiene and phenylpyrazole conferring mutations from 134 unique populations collected across the United States and Canada spanning a 14-yr period. Homozygous genotypes for the A302S mutation were found in 2 geographically distinct populations. This finding represents the first record of a non-synonymous Rdl mutation in bed bugs and identifies another mechanism by which insecticide resistance may be conferred in this species.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"740-744"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ecuador's diverse ecological regions host various Anopheles species, influencing malaria transmission dynamics. This study documents the distribution and biodiversity of Anopheles mosquitoes across Ecuador's Amazon, Coastal, and Andean regions, based on the collection of 9,882 specimens from 2017 to 2023. Morphological identification, complemented by PCR analysis of cytochrome oxidase 1 (COI) genes, revealed 32 Anopheles species. Key findings include the predominance of An. albimanus in the Coastal and Andean foothill regions and An. oswaldoi in the Amazon. Biodiversity indices highlight higher species richness in the Amazon and Coastal regions compared to the Andean region, where An. albimanus dominated. The study underscores the need for region-specific vector management strategies. In the Coastal and Andean regions, targeted indoor and peridomestic vector control is recommended, while in the Amazon, the emphasis should be on preventing human-vector interaction and biological control of immature mosquito stages. These findings enhance the understanding of Anopheles biodiversity and distribution in Ecuador, informing the design of tailored interventions to advance malaria elimination goals.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"659-666"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143775090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The larvae of Aedes aegypti (L.), an anthropophilic invasive vector species, often develop in artificial habitats in urban areas but little is known about how that environment shapes their life history or phenotypic traits. We hypothesized that container detritus, nutrients, and larval interspecific competition with the endemic mosquito, Aedes mediovittatus (Coquillett), would vary along an urban gradient in the San Juan Metropolitan Area in Puerto Rico. We also hypothesized that fine-scale variations within a 200 m buffer of the container environment would alter Ae. aegypti larval nutrients, density, and biomass. We sampled mosquito larvae, container detritus, and suspended particulate organic matter in 44 locations and characterized the surrounding environment in terms of land cover, land use, and vegetation α diversity. We show that container detritus and nutrients are influenced by fine-scale environmental variations environment, affecting Ae. aegypti and Ae. mediovittatus larvae phenotypic traits and nutrient composition. Aedes aegypti was the dominant species in all samples across the urban gradient. We found a negative relationship between Ae. mediovittatus larval % carbon and vegetation cover in the surrounding environment, and a negative correlation between this species' larval C:N and suspended particulate organic matter C:N. These findings suggest a potential disadvantage in nutrient allocation that could affect its competitive ability in urban areas. We found smaller and less nitrogen enriched (δ¹⁵N) Ae. aegypti in containers surrounded by higher impervious cover. The implications of these findings on potential vector disease risk across urban gradients are discussed.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144055945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used clinical cases of anaplasmosis reported to the Connecticut Department of Public Health and A. phagocytophilum prevalence data in questing I. scapularis to understand emerging geographic disease hotspots and evaluate potential association between human and I. scapularis infections. Human incidence rates were calculated per 100,000 people by county. I. scapularis infection prevalence was calculated as an acarological risk index using active tick surveillance data from the Connecticut Agricultural Experiment Station. The potential association between incidence rates and acarological risk index was analyzed using Spearman Rank correlation. From 2019 to 2020, 420 human cases of anaplasmosis were reported and 148 A. phagocytophilum-infected I. scapularis were identified in Connecticut and a significant positive correlation was identified between acarological risk index and incidence rates.

We examined the copulation dynamics of 2 key malaria vectors, Anopheles funestus sensu stricto Giles and Anopheles arabiensis Patton, under laboratory settings in Tanzania. We conducted observations in 24-h cycles and monitored copulation events and insemination of females, initially using flashlights for nighttime visibility, followed by red lights in subsequent experiments. We observed how variations in mosquito age and artificial lighting influenced mating success for these 2 mosquito species within cages under controlled conditions. We found that An. arabiensis copulated relatively soon after emergence, with 32.4% of individuals mating by day 3 postemergence, whereas An. funestus showed delayed activity, reaching a similar mating frequency by day 8. The introduction of artificial red light significantly accelerated copulation in An. funestus but did not affect An. arabiensis. Sperm transfer and mating plug delivery in over 92% of copulating pairs of both species was confirmed by dissection. Mating occurred primarily at night, with distinct peaks at 10 PM for An. arabiensis and 11 PM for An. funestus. In conclusion, our findings revealed species-specific differences in reproductive behavior, which could improve the colonization of An. funestus, a species historically challenging to rear in captivity.

Some well-known infectious diseases are transmitted from animals to humans by flea bites: murine typhus, spotted-fever, bartonelloses and plague. Particularly for plague, more than 80 species were reported vectors in the world and some are internationally renowned and have been the focus of studies over decades. In Madagascar, fleas are associated with two diseases namely tungiasis and plague. Tungiasis is neglected while it affects many primarily rural districts of the country.
