Despite the known genetic differences, the ecology of this species was not investigated separately from eastern populations of D. variabilis. Therefore, the objectives of this study were to describe the current and future areas of ecological suitability of D. similis in western North America, and to determine the bioclimatic and environmental variables of importance for ecological suitability of this species. Twenty-nine confirmed samples of D. similis from the western United States (California, Oregon, Washington, Idaho) and Canada (British Columbia) were used in species distribution model creation via MaxEnt. Seven variables were included in the final current species distribution model of D. similis: terrestrial ecoregion, degree-days below zero degrees Celsius, Hogg's climate moisture index, mean annual relative humidity, day of the year on which the frost-free period begins, precipitation as snow, and extreme maximum temperature over thirty years. Under current conditions, high levels of ecological suitability were observed in the Okanagan region of British Columbia, Washington (extending into Oregon and Idaho), and regions of coastal and inland California. Future ecological suitability were similar to the current ecological suitability under both climate scenarios (2041 to 2070, SSP2-4.5 and SSP3-7.0). The results of this study will inform public and animal health messaging and awareness.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1116-1123"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12507434/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144644460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using CDC updraft blacklight traps and larval sampling, Anopheles crucians s.l. adults (n = 84) were identified at four sites across Providenciales and North Caicos, including at Whitby Pond and Kew Highway in North Caicos, which accounted for 98% of the adults trapped. Immature An. crucians s.l. were found at a single site along Kew Highway. This is the first record of An. crucians s.l. in TCI, expanding the documented Anopheles diversity to 2 species, and taking the total number of recorded mosquito species in TCI to 12. Findings highlight the limited abundance of larvae during dry conditions, emphasizing the utility of adult trapping for Anopheles surveillance in TCI and the importance of timing larval surveys during the wetter months (June to October). This study provides baseline data for Anopheles species in TCI, demonstrating the effectiveness of blacklight updraft traps. Further research should include monthly surveillance, larval habitat mapping, and targeted control strategies to improve the understanding of Anopheles ecology and inform public health risk assessments for malaria in the region.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1366-1371"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144628355","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}

In addition, while extended thermal exposures are known to have an impact on the growth and development of blow flies throughout their life cycle less is known about the effects of acute exposure to high or low temperatures, which can also potentially impact phenotypes. The objective of this study was to estimate the heritability of development time and determine if the estimate is impacted by acute thermal shock. Development times of offspring were compared to parental development times under control conditions (25 °C), and when dams/grand dams were exposed to heat (25 °C with brief exposure to 42 °C) or cold (25 °C with brief exposure to 2 °C). Heritability values were calculated for all groups. A moderate (h2=0.510) contribution of parental phenotype was determined for the control condition. When dams or grand dams were exposed to thermal shock, this value could change considerably (h2=0 to 0.907) depending on the nature of the thermal shock and the generation exposed to the shock. These results indicate that blow fly development times may be influenced by maternal effects and the possibility of epigenetic impacts on development. Short term exposure to thermal spikes is likely to coincide with changing seasons and further work is needed to explore the potential for seasonal effects on the genetic impact of temperature on blow fly developmental variation.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1057-1065"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144628357","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}

However, deploying CO2 via dry ice, compressed gas, sugar-yeast reactions, or carbonate-acid systems can be expensive, short-lived, and labor-intensive. We evaluated the effectiveness of a commercially available, mycelium-based CO2 source (ExHale bag) for attracting mosquitoes to passive and active traps. Originally developed for greenhouse use, the ExHale bag provides sustained CO2 release for up to 6 mo. Under semi-field conditions, we compared Biogents gravid Aedes traps (BG-GAT) with and without ExHale using single or mixed groups of 3 vector mosquito species (Culex quinquefasciatus, Aedes albopictus, and Aedes aegypti). A field validation was also conducted to assess the efficacy of ExHale in both BG-GAT and BG-Sentinel traps. Our semi-field findings revealed that BG-GATs baited with ExHale captured significantly more mosquitoes than unbaited traps in both single-species (15.2 to 92.3×) and mixed-species (21.7×) tests. In field trials, ExHale-baited BG-GATs collected significantly more mosquitoes, including a broader range of species, at coastal forest (9.1×) and suburban (47.5×) sites. BG-Sentinel traps baited with ExHale also collected more female mosquitoes (1.4×), though the difference was not statistically significant. Our results indicate that ExHale, when coupled with a passive trap, provides an economical and effective trapping system for vector mosquitoes. The long effective period of CO2 production is advantageous for large-scale mosquito surveillance, particularly in remote field sites and developing countries, where CO2 may be prohibitively expensive or difficult to obtain.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1338-1343"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546594","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 aims to estimate the potential distribution of Hemiscorpius acanthocercus, identify suitable habitats, examine environmental constraints on its range, and provide insights into the species' ecology and areas at increased risk of scorpion stings. Using MaxEnt, I analyzed 63 occurrence records of H. acanthocercus with 4 temperature, 2 precipitation variables, and vegetation cover. The most influential predictors in the best-fitting distribution model were BIO4 (Temperature seasonality; 67.5%), BIO7 (Annual temperature range; 13.6%). The models indicate that the species is currently distributed along the Persian Gulf, particularly in Hormozgan, Kerman, Fars, and Sistan and Baluchestan provinces. Future projections under RCP 8.5 suggest slight northward shifts into higher latitudes, particularly into northern Hormozgan and Kerman provinces, with areas in Bushehr and Sistan and Baluchestan also predicted as highly suitable. The persistence and expansion of this medically significant species under future climate scenarios underline the importance of ongoing monitoring, public awareness campaigns, and proactive sting prevention-particularly to protect children, who are most at risk.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1079-1086"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512979","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}

However, growing resistance to chemical- and bacterial-based insecticides requires biocontrol agents with novel modes of action. Entomopathogenic fungi are good candidates for larval control due to their capability to infect mosquito larvae and their production of larvicidal compounds. In this study, we isolated a strain of Trichoderma atroviride from Aedes albopictus larvae collected in Manhattan, KS, USA. We used a laboratory-based microcosm assay to expose L3 Ae. albopictus larvae to T. atroviride conidia and culture supernatant treatments. Larvae were monitored daily for survival and development to pupae and adults. In addition, adult survival was monitored for 10 d postpupation, and wing lengths were measured to assess mosquito size. Our results revealed that T. atroviride culture supernatant was a potent larvicide toward Ae. albopictus. However, conidia by themselves were not larvicidal, indicating the major mode of killing was through toxicity exerted by the culture supernatant. We further show that larval exposure to T. atroviride supernatant delayed larval development to pupae. Sex-specific adult survival was not affected by larval exposure to T. atroviride. However, wing length of male and female mosquitoes were reduced, indicating a reduction in adult mosquito body size as compared to the control. Taken together, this study identifies the culture supernatant from a novel strain of T. atroviride as a potent larvicide of Ae. albopictus, potentially expanding the toolbox for biological control of mosquitoes.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1253-1264"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546667","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}

Compared to the more prevalent German cockroach, Blattella germanica (L.), S. longipalpa has higher temperature requirements but can infest a wider range of environments within structures under suitable conditions. Little is known about the toxicity of gel baits against S. longipalpa relative to that of B. germanica. This study evaluated toxicological responses of brownbanded and the German cockroach to commercial gel baits (Advion Evolution, Maxforce FC Magnum, Maxforce Impact, Alpine, Vendetta Plus, and 1% isocycloseram) using open test arenas and Ebeling choice boxes. Results showed that gel baits were less effective against S. longipalpa. Supella longipalpa survived 3.3 to 10.2× longer than B. germanica when exposed to most bait formulations in open arenas. Gel baits showed lower performance index values against S. longipalpa than against B. germanica in choice boxes. Based on the low performance index values, it is predicted that Maxforce FC Magnum and Vendetta Plus would be ineffective in treating S. longipalpa infestations in the field. Differences in gel bait performance between the 2 species are likely due to the lower palatability of gel baits to S. longipalpa, arising from differing nutritional and moisture requirements. Correlation and regression analysis showed a direct relationship between the data obtained from both assays for S. longipalpa. While open arena bioassays are useful in comparing the toxicity of different gel baits, choice boxes replicate field conditions more closely and allow a more accurate evaluation of bait performance.","PeriodicalId":94091,"journal":{"name":"Journal of medical entomology","volume":" ","pages":"1221-1228"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144512983","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}

As a common sanitary pest, it is capable of transmitting a variety of pathogens and is one of the species of concern in public health. However, due to its cold-adaptability, it has become an ideal species for estimating the minimum postmortem interval (PMImin) in forensic entomology. Given that there may be developmental differences among P. terraenovae populations in different regions and that the developmental model of this species is still incomplete, this study investigated the developmental patterns of P. terraenovae populations in Northwest China under seven different constant temperature conditions ranging from 16 to 34 °C. Results showed that within the temperature range of 16 to 34 °C, the egg-to-adult development duration of P. terraenovae ranged from a maximum of 713.50 ± 1.1 h at 16 °C to a minimum of 233.25 ± 1.4 h at 34 °C. Based on the developmental events, accumulated degree-hours, and developmental rates of P. terraenovae at these different temperatures, an isomorphen diagram, linear thermal summation models, and nonlinear thermodynamic Optimal SSI models were constructed. Additionally, a revised logistic model was employed to fit the changes in larval length over developmental time at different temperatures, and based on the data generated by the logistic model, an isomegalen diagram model was established.
