Australian researchers have uncovered intriguing insights into the behavior of invasive snail species, finding that they are attracted to the color red and repelled by garlic.
Published by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) on Wednesday, the study reveals unexpected preferences in pest snails that could aid in better protecting crops from their damaging effects.
In both laboratory and field tests conducted on four species of invasive snails, the research team discovered a strong preference for the color red. Contradicting previous scientific consensus that gastropods are unable to perceive color, the snails consistently gravitated towards red objects.
Moreover, the study found that garlic—and to a lesser extent, coffee—effectively repelled the snails. These findings suggest potential natural methods for deterring pest snails and safeguarding agricultural yields.
Senior Research Scientist Valerie Caron from the CSIRO expressed surprise at the snails’ attraction to red, noting it challenges the long-held belief about gastropod vision capabilities. The study’s revelations open new avenues for developing environmentally friendly pest management strategies.
