Comparison of the effectiveness of fresh and older OPP, and the sex of dead fly individuals. (A) Number of dead D. suzukii individuals found on fresh and several days old OPP extract. The oldest extract was prepared 6 days before the start of the experiment and the number of dead flies was counted 4 days after the start of this experiment. (B) The mean number of dead male (light gray bar) and female fly individuals (stripped bar) found dead on the OPP hydrogel after 4 days (paired t-test, p < 0.01, N = 7). 20 adult D. suzukii individuals of each sex were released at the beginning of each experiment in the middle of the terrarium.
