From: Toward a push–pull strategy against invasive snails using chemical and visual stimuli
Preference of four snail species for different colors in dual choice-tests under laboratory conditions. Numbers indicate the total number of individuals that made a choice for each color (n = 30 for each color duo). Snails that did not make a choice are not represented. Asterisks indicate significant preference (Chi-square test, α = 0.05; *P < 0.05; **P < 0.01).
