Yeasts as the Novel Attractant of Pomacea canaliculata

Pomacea canaliculata (golden apple snail, GAS) has become a major pest, which threatens rice cultivation especially in Asia. To control this pest, many farmers use extensively synthetic molluscicides that are not only expensive but of broad spectrum, therefore affecting non-target organisms including human beings. This study aimed to explore new biological attractant that could be used to attract the snails as an essential aspect of integrated pest control. The novel potential of isolated yeasts, identified as Candida ethanolica and Pichia kudriavzevii based on the 18S rRNA identification, as microbial-based bait for attraction of GAS was elucidated. Both the male and female GAS showed the highest moving rates towards C. ethanolica strain M2 activated in 5% molasses. This is the first report on the potential of yeasts as bait or lure for GAS which can used in integrated pest management.
