Innovative approaches to vector control: integrating genomic, biological, and chemical strategies

Abstract

Introduction: Vector-borne diseases (VBDs) remain a significant global public health challenge, disproportionately affecting low- and middle-income countries. Traditional vector control methods, particularly chemical insecticides, face increasing limitations due to the rapid evolution of resistance and environmental concerns.

Materials and methods: This review explores recent advancements in vector control, focusing on the integration of genomic, biological, and chemical strategies as innovative solutions to address these challenges. These methods include genomic tools such as CRISPR/Cas9-mediated systems, biological interventions like Wolbachia-based strategies and sterile insect techniques (SIT), and chemical innovations involving insecticides with novel modes of action and advanced delivery systems.

Results: Genomic strategies like CRISPR/Cas9 gene drives show significant potential for precisely targeting vector reproduction and pathogen spread but face ecological and ethical hurdles to widespread use. Successful biological interventions, such as Wolbachia and SIT, have proven effective in reducing vector populations, yet they demand strong community involvement and ongoing funding for scalability. Additionally, innovative chemical solutions, including new insecticides and delivery methods, tackle resistance issues while reducing environmental harm, with techniques like microencapsulation and synergists improving sustainability.

Discussion: This review highlights the importance of Integrated Vector Management (IVM) frameworks that combine genomic, biological, and chemical strategies. These integrated approaches maximize synergies while mitigating the limitations of individual methods. Key findings emphasize the potential of integrated approaches to achieve sustainable reductions in vector populations and disease transmission. However, significant challenges remain, including the need for standardized protocols, long-term effectiveness data, and considerations of ecological risks and climate change impacts.
