Behavioral responses of Protaetia brevitarsis in a Y-tube olfactometer (A) to anisole (An), n-heptanone (nH), 4-methylanisole (4-MA) and n-nonanone (nN) at a dose of 10 μg in 10 μL paraffin oil and (B) to 4-methylanisole (0.5, 1.0, 5.0, 10, 100 μg in 10 μL paraffin oil). N = 60 for each treatment. NC stands for numbers of non-response beetles. (Binomial tests: * 0.001 < P < 0.05; *** P ≤ 0.001).
