However, larvae of many common species can only be reliably identified using molecular techniques, which are not always possible. Furthermore, determining the instar stage is even more challenging, as features necessary for precise identification are often poorly documented. Oiceoptoma thoracicum (Linnaeus, 1758) is a common necrophagous beetle in the Palearctic region from the Western Europe to Japan. The species is also frequently found on cadavers of large vertebrates, including human remains, making it a promising candidate for use as a bioindicator in forensic entomology. Adults can be easily distinguished from other species; however, larvae have never been thoroughly described. The identification of O. thoracicum based on immature stages, or the differentiation of instars of this species is therefore not yet possible. The aim of this study was to provide reliable morphological characters that would allow the identification of larvae and instar stages in O. thoracicum. Quantitative and qualitative morphological characters for instar and species identification are described and illustrated. A list of described immature stages of the genus Oiceoptoma is provided.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"525-544"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560330","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}

To determine the influence of elevation on the seasonality and abundance of Ixodes pacificus nymphs in the Sierra Nevada foothills of California, we used a standardized flagging procedure to sample nymphs from rocks and logs at 16 sites during 2018 to 2020. We sampled a total of 4,720 rocks and logs during 168 surveillance events and collected 1,469 I. pacificus nymphs. Nymphal abundance was similar on rock and log substrates. Tick abundance and seasonality varied by elevation, with lower elevation sites exhibiting higher nymphal abundance and earlier seasonal activity. Nymphal activity started later and persisted longer into the summer months at higher elevation sites. Nymphal abundance on rocks and logs was not predictive of adult abundance the following year, as estimated by drag sampling for adult ticks along hiking trails within the nymph sampling areas. Overall, 4.9% and 1.4% of the tested nymphs were infected with Borrelia burgdorferi s.l. and B. miyamotoi, respectively. We found no relationship between elevation and B. burgdorferi s.l. infection prevalence, although fewer nymphs were tested from higher elevation sites. These findings advanced our understanding of I. pacificus nymphal abundance and distribution and helped improve assessment of public health risks associated with tick exposure in the Sierra Nevada foothills.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"690-699"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660208","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}

Four traps baited with sardines and 4 with bovine liver at different stages of decomposition (0 h, 48 h, and 96 h) were installed at georeferenced points for 8 h. The procedure was repeated over 4 wk. Insects were stored at -5°C for preservation until taxonomic identification was performed. Statistical analyses were conducted in R Studio, and hypothesis tests were used to evaluate bait attractiveness. A total of 5,483 Calliphoridae were collected, with a predominance of Chrysomya megacephala (Fabricius; 1794), Chrysomya putoria (Wiedemann; 1818), and Chrysomya albiceps (Wiedemann; 1819), and a lower abundance of Cochliomyia hominivorax (Coquerel, 1858), Hemilucilia segmentaria (Fabricius; 1805) and Lucilia cuprina (Wiedemann; 1830). Sardine bait at all decomposition intervals showed greater attractiveness compared to bovine liver bait. Sardine bait with 96 h attracted the highest abundance of insects, whereas fresh bait was not attractive. For bovine liver, decomposition time did not significantly influence attractiveness, with 48 and 96 h intervals being equally effective. This study enhances knowledge about the population dynamics of Calliphoridae in Campo de Santana, an important urban park in the city center of Rio de Janeiro.

Little is known about the feeding habits of mosquitoes as related to the transmission of arboviruses. We report on the identification of vertebrate hosts of 9 species of mosquitoes collected in 2003 to 2006. Blood meals of 1,223 from 9 mosquito species were identified to vertebrate species by PCR assays using the mitochondrial cytochrome b gene. Aedes dorsalis (Diptera: Culicidae) and Culiseta inornata fed only on mammals, and Aedes vexans fed almost exclusively on mammals. Aedes trivittatus fed significantly more on mammals than on birds. Culex tarsalis acquired blood meals from the most diverse group of vertebrates, frequently fed on American Robins, and did not exhibit a seasonal shift of feeding on birds to mammals. The extensive feeding of Cx. tarsalis on passerine birds and the isolation of West Nile virus (WNV) from 2 specimens that had fed on passerines supports their role in horizontal transmission of WNV. This species also transmits western equine encephalitis virus. Host feeding by Ae. trivittatus, Ae. vexans, Cs. inornata, and Ae. dorsalis in relation to their possible importance in transmission of trivittatus virus, Cache Valley virus, Jamestown Canyon virus, Potosi virus, or snowshoe hare virus is presented. The identification of host feeding behavior pattern of specific species of mosquitoes enhances our understanding of the enzootic and epizootic nature of 7 viruses in North Dakota.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"621-632"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470216","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}

These factors warrant the elucidation of its genetic structure across various physiographic regions. Adult Culicoides were captured from 14 collection locations across different physiographic areas of India. The study used 2 genetic markers, ie mitochondrial cytochrome oxidase-1 (COX-1) and nuclear ribosomal protein-S2B intron region (EPIC). COX-1 sequences of C. peregrinus from the other areas of its distribution were also considered. A high intraspecific genetic distance, ie 2.46% (within India) and 3.5% (across its distribution range) indicates the possibility of cryptic species. This vector has a relatively uniform genetic structure with a slight difference in the southern Indian population. However, the populations from different countries are genetically distinct and exhibit high genetic distances among themselves. There is evidence of demographic expansion with India as the probable ancestral region with 3 distinct lineages: India-Bangladesh, Thailand-China-Malaysia, and Australia. STRUCTURE analysis using EPIC marker (ribosomal protein-S2B intron region) depicted the distribution of 2 alleles in India but no population substructure. Pairwise FST indicated the south Indian population to have low but significant genetic differentiation with other Indian populations. More fine scale studies to ascertain the genetic differentiation of the Indian population along with direct experimental validation of vector competence is imperative to confirm C. peregrinus as the causative vector of BTD outbreaks.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"572-583"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733814","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 assesses how anthropization influences fly assemblage diversity, abundance, and their role in organic matter degradation across different areas. Three types of substrates were used: raw chicken viscera (CV), cow dung (CD), and cooked noodles with raw eggs (NE), in areas with low (LA) and high (HA) anthropization. In each area, 5 baited traps per substrate, which allowed fly entry, and 3 unexposed controls were set. The experiment was conducted 3 times, totaling 90 baited traps and 36 controls. Flies that emerged were collected on day 21. Substrate weights were recorded at the start and end of each trial. The highest abundance of species that emerged was observed in CV-HA, while the greatest species richness was recorded in CV-LA. Significant differences in fly assemblages were observed between areas. Greater degradation of CV was recorded in HA, whereas CD showed a significant difference with control traps only in LA. Substrate degradation was positively related with fly abundance in CV-HA, and with both fly abundance and species richness in CD-LA. This study highlights the pivotal role that sarcosaprophagous flies play in organic matter decomposition, health risks related to organic waste accumulation, and nutrient cycling across anthropogenically altered environments, revealing significant variations in decomposition rates and the composition of fly assemblages. Also, we emphasize the potential of sarcosaprophagous flies as bioindicators for assessing anthropogenic impacts on ecosystems.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"560-571"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660207","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}

Common mechanisms of resistance include the target-site mutation, kdr, and increased levels of detoxification enzymes, such as mixed-function oxidases, GSTs, and esterases. The goal of this study was to compare the prevalence of kdr mutations (L1014F and L1014S) and detoxification enzymes between pyrethroid susceptible and resistant Cx. tarsalis individuals. Individual mosquitoes, categorized by resistance status from permethrin bottle bioassays, were prepared for both molecular and enzymatic testing by separating the legs of a mosquito from the remaining body. Legs were used to test for the presence of kdr mutations, while the bodies were used to test for the activity of detoxification enzymes. The number of phenylalanine (F) alleles present at the kdr target-site as well as levels of GST were increased in mosquitoes that survived the bottle bioassay compared to those that were knocked down. Individuals with 2 F alleles and an active GST level greater than or equal to 0.052 µg/ml showed a higher survival rate than either mechanism independently demonstrating resistance to pyrethroids in Cx. tarsalis is likely the result of multiple resistance mechanisms acting collectively. Further work is needed to determine the interplay of multiple resistance mechanisms to achieve phenotype resistance in this mosquito species.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"584-592"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560325","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}

Untapped alternatives exist in adjacent pest-management industries, but translation and validation for various technologies is still ongoing. The attractive targeted sugar bait (ATSB) strategy is a formulation platform that is amenable to toxicants not otherwise widely used for adult mosquito control techniques and equipment. To find fast-acting, effective toxicants for ATSB, choice assays were conducted using fipronil, spinosyn, dinotefuran, clothianidin, imidacloprid, bifenazate, indoxacarb, abamectin, and λ-cyhalothrin against Aedes aegypti (L.) (Diptera: Culcidae) as a model system. Active ingredients were emulsified in propylene glycol, a secondary toxicant and formulation aid in ATSB, and sucrose solution. Treatments were presented in tandem with unadulterated 10% sucrose in all assays. In both 24-h mortality and fecal droplet analysis, indoxacarb was ingested similarly as often as the sugar water-only control group and yielded the overall lowest mortality. Imidacloprid, λ-cyhalothrin, and abamectin were all readily ingested, and in some cases the fecal droplet analysis indicated bias towards consumption of the treated sugar solutions. Mortality in the first 24 h was over 95% for the aforementioned toxicants, supporting that they both kill in limited time and have a suitable palatability or repellency response profile with mosquitoes. But imidacloprid and λ-cyhalothrin (resistance) and imidacloprid (pollinators) have roadblocks for use in ATSB because of potential nontarget impact to pollinators and prevalent insecticide resistance issues. However, abamectin appears to be a promising ingredient for future ATSB formulations to establish quick vector interruption and improve insecticide class variety for resistance management.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"735-739"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560329","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}
