Although dry ice has been the historical benchmark, compressed gas cylinders can be used in tandem with a gas regulator to control CO2 flow rate more precisely. The literature is sparse on best practices regarding how to choose or test regulators. We evaluated four commercially available regulator types from beverage and welding suppliers and compared them to a previously tested regulator used at the Salt Lake City Mosquito Abatement District (SLCMAD). Using environmental chambers, we simulated both the temperature drop of spring/fall or summer nights down to 9°C, as well as daytime highs within the seasonal expectations of the central ranges of Utah, up to 42°C. Two regulators failed to maintain calibrations in these screenings. The remainder were vetted by acquiring duplicates and rerunning the simulations with inverted temperature exposures, starting low and heating up, instead of starting warm and cooling down in the first tests. The remaining regulators were tested in the field for validation. After 56 trap cycles with 15 duplicates of three regulator models, general failure rates in real applications all decreased below 5% of total uses. The preexisting regulator used by SLCMAD performed well in simulations, but had double the failure rate of the other screened models. We use this study to highlight the scarcity and importance of conducting evaluations on the existing protocols or equipment for public health vector control programs and provide recommendations for addressing operational usage.</p>","PeriodicalId":17192,"journal":{"name":"Journal of the American Mosquito Control Association","volume":" ","pages":"143-150"},"PeriodicalIF":1.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, their high safety profile makes them ideal candidates for environmental applications. The current study evaluated the insecticidal potential of Psidium guajava and Piper betle leaf extracts against Aedes aegypti through in vitro and in silico approaches. In laboratory studies, the LC50 of n-hexane extract of P. guajava and ethyl acetate extract of P. betle were 95.21 ppm and 217.7 ppm after 24-h exposure, respectively. The gas chromatography-mass spectrometry analysis identified important bioactive compounds, including caryophyllene (21.2%), globulol (19.9%), squalene (8.3%), and γ-muurolene (6.6%) in P. guajava and hydroxychavicol (57%), 5-allyl-2-hydroxyphenyl acetate (5.6%), phytol (2.3%), and safrole (1.8%) in P. betle extract. In silico analysis of these compounds with target proteins acetylcholinesterase (AChE), S-adenosylhomocysteine hydrolase (SAHH), and sterol carrier protein-2 (SCP-2) in Ae. aegypti larvae showed that squalene from P. guajava had a higher binding affinity with AChE (-8.4 kcal/mol) compared to globulol (-7.3 kcal/mol). However, conventional hydrogen bonding, which is stronger and more stable, was observed in the globulol-AChE complex. The in silico analysis of P. betle phytochemicals demonstrated that hydroxychavicol, phytol, and safrole had binding affinities of -6.1 kcal/mol, -6.0 kcal/mol, and -6.0 kcal/mol with SAHH, respectively. A minor increase in binding affinity was observed in the safrole-SAHH complex (-6.1 kcal/mol), whereas no change was observed in the 5-allyl-2-hydroxyphenyl acetate-AChE complex (-5.9 kcal/mol) in 2-ligand binding mode. Since these bioactive compounds target the important proteins in the developmental processes of mosquito larvae, they can further be evaluated to design natural and organic insecticides against Ae. aegypti.</p>","PeriodicalId":17192,"journal":{"name":"Journal of the American Mosquito Control Association","volume":" ","pages":"126-133"},"PeriodicalIF":1.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the last decade, arboviral pathogens transmitted by invasive mosquito species have increased substantially in the southeastern region of the USA (\"the Southeast\"). Early detection of invasive mosquitoes is an important component of an integrated mosquito management (IMM) plan. To determine the capacity of the southern region of the USA to conduct invasive mosquito surveillance, the Mosquito Biodiversity Enhancement and Control of Non-native Species (BEACONS) working group conducted a survey in 2021 in seven US southern states: Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina.

Here we report the results about the status of an IMM program and the techniques used for mosquito and pathogen surveillance in the Southeast. Results reveal several gaps in surveillance for invasive mosquito species, compromising the ability for early detection and rapid response. Further, we identified a lack of arbovirus testing, which could result in inadequate arboviral risk assessment and may increase the risk of human and livestock to acquire arboviral infections.

The Uranotaenia species has been reported to be able to develop in small quantities of water, similar to Aedes aegypti. The genus is unusual in that, unlike the 3 larger genera where females feed on homeotherms (warmbloods), mammals and birds, Uranotaenia spp. are known to feed only on poikilotherms (cold-blooded animals), amphibians, reptiles, leeches, annelid worms, and possibly snails, and, as such, are not a public health concern.

During that period, the number of cases of LACV disease declined to 1 and 2 cases in 2003 and 2004, respectively, and 0 reported cases within La Crosse County, WI, since 2005. We surveyed Ae. triseriatus populations in La Crosse and Trempealeau counties, WI, during the summers of 2020-2021 to determine whether the decline in LACV disease cases corresponded to a possible decline in Ae. triseriatus populations, and whether the invasive species, Ae. japonicus, is competing with and replacing Ae. triseriatus. We sampled containers for larvae and collected eggs using oviposition (OP) traps. We collected 606 and 20,020 mosquitoes in 2020 and 2021, respectively. Overall, we found a lower proportion of Ae. japonicas than Ae. triseriatus in natural oviposition sites in 2020 (n = 72 and 224 larvae, respectively; z = 8.78, P < 0.0001), in OP traps in 2020 (n = 5 and 199, respectively; z = 13.51, P < 0.0001), and in OP traps in 2021 (n = 358 and 19,099, respectively; z = 134.31, P < 0.001).
