This article addresses dual goals of (i) collecting relevant data on potential vector mosquitoes and (ii) delivering learning outcomes among participants in a citizen science mosquito surveillance program. Mozzie Monitors uses an e-entomology approach to collect and identify mosquitoes of medical importance. This study used quantitative, qualitative, and mixed method approaches, comprised of before and after longitudinal surveys, in-depth interviews and descriptive assessment of mosquito attributes to assess participants’ educational gains and data collection scalability. Results showed that mosquito abundance and diversity differed in each study location, with Aedes notoscriptus (Skuse) being the most common mosquito reported in all areas. Citizen scientists were predominantly women over 50 and highly educated. The before-and-after analysis showed that participants learned how to identify the most common mosquito species after participating in the program. They also improved their technical skills in mosquito photography, increasing the rates of identifiable photos. Finally, participating in this citizen science program resulted in behavior changes, with participants starting to look for mosquito eggs and larvae in their backyards to manage mosquito populations. The mixed methods used in this research showed increased participants’ confidence, self-efficacy, and engagement throughout the trial. Overall, this study demonstrated the potential of Mozzie Monitors to contribute to the dual goals of mosquito data contribution and citizen scientists’ educational outcomes for improved public health.","PeriodicalId":16325,"journal":{"name":"Journal of Medical Entomology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional PCR was performed on 469 Ae. aegypti and 349 Ae. albopictus. We did not discover kdr mutations in Ae. albopictus, but 2 nonsynonymous kdr mutations, V1016I (found in 101 mosquitoes) and F1534C (found in 29 of the mosquitoes with the V1016I), were detected in Ae. aegypti. These kdr mutations were present in all specimens that were successfully sequenced for both IIS5-S6 and IIIS6 regions, which included samples collected from 8 of the 10 provinces of Panama. No other kdr mutations were found in Ae. aegypti, including V1016G, which has already been reported in Panama. Findings suggest that the V1016I-F1534C variant is prevalent in Panama, which might be related to the introduction and passive movement of mosquitoes as part of the used-tire trade. However, we cannot rule out the possibility that selection on de novo replacement of kdr mutations also partially explains the widespread distribution pattern of these mutations. These 2 ecological and evolutionary processes are not mutually exclusive, though, as they can occur in tandem. Research in Panama needs to calculate the genotypic and allelic frequencies of kdr alleles in local Ae. aegypti populations and to test whether some combinations confer phenotypic resistance or not. Finally, future studies will have to track the introduction and spreading of new kdr mutations in both Aedes species.","PeriodicalId":16325,"journal":{"name":"Journal of Medical Entomology","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142184903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite numerous studies on the influence of these factors, including the impact of xenobiotics, there are currently no robust tools available for making corrections to this estimation considering concurrently all variables. In an attempt to propose an exploratory and descriptive statistical model to analyze the simultaneous effect and interaction of different variables on larval growth, this study aimed to compare the effect of malathion on the growth of Megaselia scalaris (Loew, 1866) (Diptera: Phoridae) raised in malathion-spiked porcine muscle, under controlled and uncontrolled temperature and humidity conditions (environmental conditions). Larvae were also reared using various growth media.

We built several models based on current climate and projected future climate changes using a maximum entropy approach. A total of 314 records of the A. cajennense complex (65.9%; n = 207), A. ovale (22.9%; n = 72), and the A. maculatum complex (11.1%; n = 35) were obtained. Amblyomma ovale has a current distribution in the Pacific, Caribbean and Andean regions and could be potentially found in the Amazon. Amblyomma maculatum has a current distribution in the Andean and could potentially be found in the Caribbean and Orinoco regions. Amblyomma mixtum can be found near the Caribbean Sea and in the Pacific region, and A. patinoi is likely to be found in the Andean region and the Caribbean. In 2070, it will be possible to find an expansion of A. ovale and A. maculatum and a decrease of A. mixtum and A. patinoi. The variables that best predict the distribution of these species are isothermality (small fluctuations in temperature) and annual precipitation.

Although few of either group had formal programs, many were engaged in T/TBD-related activities. Many MCAs rated their ability to assume T/TBD responsibilities as high or moderate, while most HDs rated their capabilities as low. With the exceptions of lack of sustainable funding and possible legal constraints, the groups differed regarding perceived barriers to program creation and maintenance. Both groups envisioned comprehensive programs emphasizing public education, but program priorities differed between the groups. MCAs were willing to include most program activities, while HDs felt that some activities should be the responsibility of other agencies. MCAs were generally more familiar than HDs with tick control methods and while both groups would include control in a comprehensive program, both would limit control to public lands. Estimated program costs varied widely, probably reflecting responding agency size and complexity of envisioned programs.
