In California, these invasive mosquitoes are now present in over 300 cities across 25 central and southern counties. The In2Care® Mosquito Station, which uses biological control agents to target Aedes mosquitoes, has shown promise when integrated into existing integrated vector management strategies. This study evaluated the impact of pre-season deployment of In2Care stations on Ae. aegypti populations. Two cohorts were established: 1 with 17 sites deploying stations pre-season (April-November), and another with 15 sites deploying during peak season (July-November), maintained during 2022-2024. Monthly BG-2 Sentinel trap data showed a significant reduction in Ae. aegypti abundance at pre-season In2Care sites: from 31.2 mosquitoes/trap-night in 2022 to 20.1 in 2023 and 13.2 in 2024, with a year-to-year reduction of 34-36%. Peak-season In2Care sites showed a 24-36% reduction in mosquito abundance four weeks post-deployment. Pre-season In2Care sites maintained 22-34% lower mosquito abundance than peak-season sites. These results demonstrate that early deployment of In2Care stations prior to the mosquito season significantly reduces Ae. aegypti populations and reinforces the existing integrated vector management programs.</p>","PeriodicalId":17192,"journal":{"name":"Journal of the American Mosquito Control Association","volume":" ","pages":"134-142"},"PeriodicalIF":1.0,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144659516","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}

The European Mosquito Control Association showcased European expertise in mosquito control at this event, strengthening ties with AMCA. With the rapid development of technology, including artificial intelligence, robotic techniques, and tools, mosquito control professionals will face new challenges and opportunities for exploration.

We evaluated four host-seeking trap configurations (Centers for Disease Control and Prevention [CDC] Light trap, BG-Pro with BG lure, and BG-Sentinel 2 with and without BG lure) via two 4 × 4 Latin square field studies. Over the course of 128 trap-days, 436 mosquitoes were collected with the two most common species being Aedes triseriatus (n = 156, 35.8% of total) and Ae. albopictus (n = 182, 41.7% of total). The BG-Pro, on average, collected approximately 3 times more female Ae. triseriatus than the CDC light trap or the BG-Sentinel with BG lure. Similarly, the odds of collecting Ae. triseriatus with the BG-Pro trap were 3.02 times (95% CI: 1.96-4.67) than the CDC light trap; statistically greater than any other trap. There was no statistical difference in the odds of collecting Ae. triseriatus by the BG-Sentinel 2 (irrespective of lure presence) when compared to the CDC light trap as the reference.

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.

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.
