This, however, is being hampered because of increased insecticide resistance to synthetic chemicals. Currently, environmentally friendly botanical agents are gaining interest globally as they possess promising mosquitocidal properties. In this study, the larvicidal activity of essential oils extracted from the leaves of Jamaican Hyptis verticillata and Pimenta dioica were evaluated at 24 h against Ae. aegypti, utilizing a modified World Health Organization bioassay. Subsequent gas chromatography-mass spectrometry analysis of the extracts revealed that the most abundant compounds of H. verticillata and P. dioica were cadina-4,10(15)-dien-3-one and eugenol, respectively. A dose-dependent response was noted, and LC50 values of 16.06 ppm and 56.23 ppm were obtained for H. verticillata and P. dioica respectively, against the Rockefeller laboratory strain of Ae. aegypti. Evaluation of H. verticillata against field strains showed that increased pigmentation was among the main phenotypical changes observed post treatment. The calculated resistance ratios varied across sites, with RR50 values ranging from 0.727 in Duhaney Park to 1.578 in Savanna La Mar, indicating overall low resistance across all strains. The current findings support the potential use of essential oils as alternative larvicidal agents in Jamaica.</p>","PeriodicalId":17192,"journal":{"name":"Journal of the American Mosquito Control Association","volume":" ","pages":"60-69"},"PeriodicalIF":1.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147480884","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}

Dengue virus presents extremely high risk of infections to humans in locations where cities are overcrowded and harbor large numbers of container-inhabiting Aedes species. In 2023, both Nepal and Bangladesh suffered unprecedented and extremely high case numbers of more than 51,000 and more than 321,000, respectively.

Vectech's Identification-X (IDX) machine offers an innovative way to identify and count adult mosquitoes and train artificial intelligence (AI) software. In collaboration with Vectech, staff at Placer Mosquito and Vector Control District (District) have identified and imaged ∼5,100 adult mosquitoes since 2021. Using the most recent software update (v5.0.4), we aimed to evaluate accuracy improvements by incorporating a diverse range of mosquito genera and species. To achieve this, 100 female specimens of 10 wild-caught mosquito species were imaged. The species included Anopheles freeborni, An. franciscanus, Culex tarsalis, Cx. pipiens, Cx. stigmatosoma, Cx. erythrothorax, Aedes vexans, Ae. melanimon, Ae. aegypti, and Ae. sierrensis. Of the 10 species analyzed, 6 had an identification accuracy of 96-100%. Given the software's current accuracy for Cx. tarsalis, follow-up examinations were conducted to determine at what point consistent specimen degradation impacted the ability of the IDX to correctly identify mosquito samples of this species. Finally, we compared the identification accuracy and speed of individual vector control technicians (VCTs) with the imaging accuracy and speed of the IDX machine to determine operational efficiency of this device within a mosquito surveillance program. Results indicated that the IDX machine is as accurate and efficient as a vector control technician with 22 months of experience but is prone to misidentification of morphologically similar mosquito species when specimens are degraded.</p>","PeriodicalId":17192,"journal":{"name":"Journal of the American Mosquito Control Association","volume":" ","pages":"230-236"},"PeriodicalIF":1.0,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145346000","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}
