Larval Bioassay > Dosing the beakers
  1. Add 100 ml of distilled water to each of the beakers.
  1. Add 1 ml of the appropriate premixed stock solution (mixed in previous step) for the chemical you are working with and mix with the distilled water already in the beaker.
  1. Be sure to make control beakers to run along side your insecticide beakers. Follow the same steps as above but do not add any chemical other than 1 ml ethyl alcohol to the beaker.
  1. It is a good idea to let the beakers 'breath' at least 10-15 minutes before use, to allow the alcohol to evaporate from the beaker.
