The images were taken to assess whether dsSec23 and dsVatpG were able to decrease the feeding activity of pre-aestivation cabbage stem flea beetle compared to dsGFP control treatment. The Random 6 DPT files were for preliminary investigation and VATP/GFP/Sec23 1-4 files were the actual investigation. 2 cm2 oilseed rape leaf disks were provided 4 days after oral treatment of the dsRNAs and the feeding area was calculated by substracting the remaining leaf area 2 days later (6 days after the dsRNA treatments). THe raw data calculated using imageJ is provided as consumed leaf area.xlsx
