PacVec’s overview video on testing for resistance in larval mosquitoes 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. Watch additional videos for more information on testing for resistance in larval mosquitoes to bacterial larvicides, spinosad, sphaericus, and methoprene.
