There is a need for robust regulatory frameworks and public engagement to address concerns about the safety and acceptability of these technologies. The potential for gene drives to spread beyond the target population and affect other species or regions also raises questions about the control and reversibility of such interventions (Adolfi et al., 2020). Furthermore, the ecological impacts of reducing or altering mosquito populations through genetic modifications must be evaluated. Mosquitoes play various roles in ecosystems, including serving as food sources for other animals. The reduction or elimination of mosquito populations could have cascading effects on biodiversity and ecosystem stability. Therefore, it is crucial to conduct comprehensive ecological risk assessments and develop strategies to mitigate potential negative impacts before implementing genetic control measures (Adolfi et al., 2020). 5 Future Directions 5.1 Innovations in genomic technologies The field of mosquito vector competence and pathogen transmission is poised for significant advancements through the development and application of novel genomic technologies. One promising area is the use of Cas9/gRNA-mediated gene-drive systems, which have shown potential in population modification and suppression strategies. These systems can effectively reduce the number of vector insects or alter their ability to transmit pathogens, as demonstrated in Anopheles stephensi (Adolfi et al., 2020). Additionally, the optimization of physical genome mapping techniques, such as the use of fluorescence in situ hybridization (FISH) for cytogenetic mapping, has improved the accuracy of genome assemblies in mosquitoes with large, repeat-rich genomes (Masri et al., 2021). Another innovative approach is the development of targeted amplicon sequencing methods to screen for insecticide resistance mutations. This method allows for rapid and cost-effective identification of single nucleotide polymorphisms (SNPs) and small insertions and deletions (indels) in genes associated with resistance, facilitating high-throughput monitoring of insecticide resistance in mosquito populations (Collins et al., 2022). Furthermore, advances in oral RNA interference (RNAi) technologies offer new avenues for vector control by enabling the delivery of species-specific interfering RNA pesticides to mosquitoes, potentially overcoming the limitations of traditional insecticides (Wiltshire et al., 2020). The integration of these genomic technologies with high-throughput detection methods, such as the use of FTA cards for saliva collection, can enhance the efficiency of monitoring arbovirus transmission in mosquito populations (Honório et al., 2020). Additionally, the development of site-directed integration and cassette exchange systems, such as the φC31-mediated integration, provides precise and stable methods for genetic modification of mosquito genomes, enabling reproducible transgene expression and facilitating comparative analyses of phenotypes (Adolfi et al., 2021). 5.2 Integrated vector management The insights gained from genomic technologies can be integrated into broader vector management strategies to enhance disease control. For instance, the identification of insecticide resistance mutations through targeted amplicon sequencing can inform the development of more effective insecticide formulations and deployment strategies, thereby mitigating the impact of resistance on vector control programs (Collins et al., 2022). Additionally, the use of gene-drive systems for population modification can be combined with existing vector control measures, such as insecticide-treated nets (ITNs), to achieve more sustainable reductions in vector populations and disease transmission (Selvaraj et al., 2020). 5.3 Research gaps The application of RNAi-based pesticides offers a novel approach to integrated vector management by providing a species-specific and environmentally friendly alternative to chemical insecticides. This technology can be incorporated into existing control programs to address the growing issue of insecticide resistance and enhance the overall effectiveness of vector control efforts (Wiltshire et al., 2020).
