Fig 1.
Mean (± SEM) percent of total D. suzukii released in an arena captured inside the traps that contained water control vs. water control, TD or OR1 vs. water control, TD vs. OR1, and TD + spinosad vs. OR1 + spinosad.
Significant statistical difference is shown (paired t-test; α = 0.05); * (P<0.1), ** (P<0.01), *** (P<0.001), and **** (P<0.0001).
Fig 2.
Mean (± SEM) percentage of total D. suzukii released in an arena captured inside the traps that contained various ACTTRA SWD treatments vs. blueberry fruits.
Significant statistical difference is shown (paired t-test or Wilcoxon matched-pairs signed rank test; α = 0.05); * (P<0.05), and ** (P<0.01).
Fig 3.
The attractivity index (AI) in percentage.
Significant statistical difference from zero is shown (sign test; α = 0.05); ns (P>0.05), and * (P<0.05). A significant positive mean AI value indicates an overall adult D. suzukii attraction to TD, OR1, HOOK SWD, or water, depending on treatment over the alternate choice of blueberries. A significant negative mean AI value indicates an overall attraction of adult D. suzukii to blueberry over the corresponding treatment choices.

Overall percent mean mortality (± SEM) of adult D. suzukii (A), and the number of progeny (± SEM) (B) emerged from blueberries per arena in laboratory no-choice bioassay trial with different treatments. The experiment was replicated in GA, NJ, and FL laboratories.
