What is likely included in the evaluation of a new insecticide formulation for adulticiding?

The evaluation of a new insecticide formulation for adulticiding often involves using sentinel caged mosquitoes. This method allows researchers to assess the effectiveness of the insecticide by exposing these mosquitoes to the treatment. By monitoring the mortality rates of the sentinel mosquitoes, it is possible to determine how well the insecticide performs in killing adult mosquitoes. This approach provides controlled conditions, minimizing external variables that could affect the outcome and allowing for a more accurate assessment of the product's efficacy.

The other methods, like surveying residents or inspecting visual populations, focus more on anecdotal or less controlled evidence of mosquito activity, which may not provide a clear or objective measure of the insecticide's effectiveness. Sampling larvae would be relevant for understanding breeding populations, but it does not directly evaluate the impact on adult mosquitoes that the insecticide targets.
