238 - Product Stewardship: Developing Best Practices for Monitoring Resistance for Spinosad

Abstract: As the demand for effective mosquito control solutions grows globally, the emergence of resistance within mosquito populations poses a significant challenge to the efficacy of traditional chemistries and active ingredients. To combat this, proactive, effective monitoring of resistance must be conducted by both end users and developers alike to ensure efficacy, determine best practices for applications, and extend the use of available tools.

This talk will focus on a proactive approach for measuring resistance levels in various mosquito populations across diverse geographic regions to inform product stewardship practices for Spinosad, a natural insecticide derived from the fermentation of the bacterium Saccharopolyspora spinosa. Methods explored for assessing the susceptibility of mosquito populations to Spinosad will include tactics such as standardized bench-top cup bioassays to identify trends in resistance development over time and across different environments.

The results will serve as a foundation for developing best management practices, enhancing the stewardship of Spinosad, and ultimately contributing to public health efforts in controlling mosquito-borne diseases.
