The Pacific Southwest Center of Excellence in Vector-Borne Diseases (PacVec) has released a video providing an overview of resistance testing for larval mosquitoes. The video is available on YouTube. The video discusses the rationale for monitoring resistance in mosquitoes, an overview of dose responses and how the dose response changes as resistance to larvicides evolves in a mosquito population, the different types of larval mosquito control agents, the supplies needed for carrying out bioassays, bioassay set-up and making stock solutions of control agents, and interpreting the bioassay results. The supplementary document includes hard copies of the tables and many of the figures in the video, summative assessments of some of the content, examples of a datasheet and probit paper, and additional information.
