Mortality recorded in C. brunneus weevils in the oral bioassays administering dsRNA specific for prosα2, rps13 and snf7 at (a) 30 μg dsRNA/ml diet, (b) 10 μg dsRNA/mL diet and (c) 1 μg dsRNA/mL diet. dsGFP was used as a control. Three biological repititions of the experiment were performed, each starting with a sample size of 20–25 individuals per treatment group. The figures give the means of these replicates. Error bars represent standard deviations.
