Effect of OPP dilution and reduced NaCl concentration on the number of dead flies. (A) The number of dead D. suzukii individuals counted on top of the OPP hydrogel after 4 days, when it was either offered fresh or 1:2 and 1:5 diluted with tap water. (B) The number of dead D. suzukii individuals counted after 4 days on top of the OPP hydrogel when different concentrations of NaCl were used for the extraction of OPP from orange peels.
