Systematic reviews and meta-analyses highlight the effectiveness of community-based vector control interventions against dengue. Engaging communities in activities like source reduction, awareness campaigns, and household container management significantly reduces Aedes aegypti populations and, in some cases, dengue incidence. These interventions require strong community participation, proper education, and continuous support from health authorities [1].
Strengthening integrated vector management (IVM) strategies against arboviral diseases across the Americas presents both challenges and opportunities. Key hurdles include fragmented surveillance systems, insecticide resistance, and limited resources. However, potential exists for improved inter-sectoral collaboration, innovative technologies, and community participation to enhance the effectiveness and sustainability of vector control efforts in the region [3].
Genetic control strategies for mosquitoes are evolving, encompassing population suppression and population replacement approaches. Techniques like sterile insect technique (SIT), incompatible insect technique (IIT), and gene drives aim to reduce mosquito populations or render them incapable of transmitting pathogens. These innovative tools move beyond traditional pesticide-based methods by targeting molecular mechanisms and offer diverse applications [9].
Advancing mosquito gene drive technologies for malaria elimination requires significant regulatory and research consideration. While gene drive shows promise for suppressing or modifying vector populations, its responsible development demands robust regulatory frameworks, thorough ecological risk assessments, and active public engagement. Addressing these aspects is crucial for translating gene drive from laboratory research to real-world application [2].
The deployment of Wolbachia-infected Aedes aegypti mosquitoes represents a novel intervention for controlling arboviral diseases such as dengue, Zika, and chikungunya. Wolbachia bacteria can block virus transmission or suppress mosquito numbers, providing an environmentally friendly alternative to traditional insecticide-based methods. Field deployments demonstrate the operational viability and public health impact of this approach [7].
A systematic review of novel vector control tools and strategies for dengue prevention and control highlights various innovative approaches. These include new insecticide formulations, improved surveillance techniques, and biological control methods like Wolbachia-infected mosquitoes. Diversifying vector control arsenals is vital to combat growing insecticide resistance and enhance the overall efficacy of dengue prevention programs [4].
Indoor residual spraying (IRS) with various insecticides has been assessed for its effectiveness on mosquito populations and malaria incidence. Findings confirm that IRS remains a highly effective intervention for reducing mosquito densities and malaria transmission. Its efficacy relies on careful selection of insecticides based on local resistance profiles and consistent monitoring [5].
Larval source management (LSM) plays a significant role in malaria control by targeting mosquito breeding sites. It effectively reduces mosquito vector densities and can contribute to lowering malaria incidence, particularly in urban or peri-urban settings where breeding sites are identifiable. LSM is most effective when integrated into broader control strategies [6].
Spatial repellents offer a promising complementary tool for malaria prevention and control. These compounds release volatile chemicals that disrupt mosquito host-seeking behavior, thereby reducing human-vector contact without directly killing mosquitoes. They provide protection in outdoor settings or areas where conventional interventions like bed nets are less effective, filling critical gaps in current malaria control strategies [8].
Advances in remote sensing and Geographic Information Systems (GIS) significantly enhance vector-borne disease surveillance and control programs. These technologies facilitate detailed mapping of vector habitats, risk stratification, and targeted intervention strategies. Integrating spatial technologies improves the efficiency and effectiveness of vector control efforts through real-time data and predictive models [10].
Effective vector control relies heavily on community involvement and established methods. Community-based interventions, such as source reduction, awareness campaigns, and household container management, significantly reduce Aedes aegypti populations and dengue incidence when coupled with strong public participation and health authority support [1]. Integrated vector management (IVM) strategies for arboviral diseases in the Americas face challenges like fragmented surveillance and insecticide resistance. Still, opportunities exist through improved inter-sectoral collaboration and continued community engagement [3]. Traditional chemical methods like indoor residual spraying (IRS) remain highly effective in reducing mosquito densities and malaria transmission, provided insecticides are carefully selected based on local resistance profiles [5]. Similarly, larval source management (LSM), targeting mosquito breeding sites, significantly lowers vector densities and contributes to malaria control, especially in urban areas when part of an integrated strategy [6].
Innovative genetic and biological approaches are reshaping vector control. Genetic control strategies, including sterile insect technique (SIT), incompatible insect technique (IIT), and gene drives, focus on population suppression or replacement to prevent pathogen transmission [9]. Gene drive technologies, in particular, hold immense promise for malaria elimination but necessitate robust regulatory frameworks, thorough ecological risk assessments, and public engagement for responsible deployment [2]. Another key biological intervention involves the deployment of Wolbachia-infected Aedes aegypti mosquitoes. This method effectively blocks virus transmission or suppresses mosquito numbers for arboviral diseases like dengue and Zika, offering an environmentally friendly alternative to traditional methods [7]. Novel vector control tools for dengue further include new insecticide formulations and improved biological control methods, emphasizing the need to diversify arsenals against insecticide resistance [4].
Challenges such as growing insecticide resistance and fragmented surveillance systems demand a multi-faceted approach. Strengthening integrated vector management (IVM) involves addressing these hurdles through innovative technologies and stronger collaborations [3]. For instance, the effectiveness of indoor residual spraying requires constant monitoring of local resistance profiles to maintain its efficacy [5]. Diversifying vector control tools, as seen in dengue prevention efforts, directly combats insecticide resistance by introducing new insecticide formulations and other novel methods [4]. Complementary tools like spatial repellents offer additional layers of protection. These repellents disrupt mosquito host-seeking behavior without killing the insects, protecting individuals in outdoor settings or areas where conventional interventions are less effective, thereby filling crucial gaps in malaria control strategies [8].
Technological advancements significantly bolster surveillance and control efforts. Remote sensing and Geographic Information Systems (GIS) enhance vector-borne disease surveillance by enabling detailed mapping of vector habitats, risk stratification, and the implementation of targeted intervention strategies. These powerful tools provide real-time data and predictive models, improving the efficiency and effectiveness of control programs [10]. Integrating these spatial technologies is key to optimizing resource allocation and enhancing epidemiological monitoring, representing a modern approach to managing vector-borne disease threats.
Global efforts to combat vector-borne diseases involve a diverse and evolving array of strategies. Community-based interventions for dengue, emphasizing source reduction and awareness, have proven effective in reducing mosquito populations when supported by health authorities and public engagement. Concurrently, integrated vector management (IVM) is crucial for arboviral diseases, though it faces challenges like fragmented surveillance and insecticide resistance. Advances in genetic control, including gene drive technologies and methods like sterile insect technique (SIT) and incompatible insect technique (IIT), offer promising avenues for population suppression or modification, particularly for malaria. These innovative biological tools, such as the deployment of Wolbachia-infected Aedes aegypti mosquitoes, provide environmentally friendly alternatives to traditional chemical controls for diseases like dengue and Zika. Traditional interventions like indoor residual spraying (IRS) for malaria and larval source management (LSM) remain vital, with their efficacy dependent on careful insecticide selection and targeted application. The emergence of insecticide resistance drives the need for novel tools and diversified control arsenals. Complementary strategies like spatial repellents help reduce human-vector contact, especially in settings where conventional methods are insufficient. Furthermore, technological advancements in remote sensing and Geographic Information Systems (GIS) significantly enhance surveillance and allow for more targeted and efficient control programs. Overall, a comprehensive, integrated approach combining community participation, traditional methods, advanced biological and genetic tools, and cutting-edge surveillance technology is essential for sustainable vector control.
