The plots below give an overview of substances for which experimental assessments of efficacy against midges are available. Please note that experimental protocols differed greatly: studies could have many different substance application methods, from different doses and frequencies, to different time of exposure. The box-plots give an overview of the range of efficacy reported, but direct comparisons can only be drawn by looking at the full details available on the data for each experiment (the full datasets are available, see left panel).
