Since the 1980s, freshwater apple snails, including Pomacea canaliculata, Pomacea maculata, and their hybrid, have been introduced into various freshwater ecosystems. While P. canaliculata has spread to temperate East Asia, P. maculata and the hybrid are rarely found in this region. This study compared the growth rate, winter survival rate, and feeding efficiency of these snails on rice seedlings, suggesting that P. maculata could become a serious rice pest in temperate regions, similar to P. canaliculata, if introduced from warmer regions under global warming. Further biological examination is needed to assess the risk of this snail in detail.
Since the 1980s, the freshwater apple snails, Pomacea canaliculata, Pomacea maculata, and their hybrid, have been introduced into a wide range of freshwater ecosystems in tropical to temperate regions. Although P. canaliculata has become established in temperate East Asia, P. maculata and the hybrid are rarely found in this region. To evaluate the risk of P. maculata and the hybrid particularly as rice pests in temperate regions, we compared growth rate, winter survival rate, and feeding efficiency on rice seedlings of these snails with P. canaliculata. When P. maculata and P. canaliculata hatchlings were reared under laboratory or field conditions, the adult P. maculata had larger shells than adult P. canaliculata. Neither P. maculata nor F1 hybrids could survive winter in a simulated drained paddy field, and only a few individuals of P. maculata and F1 hybrids overwintered successfully in freshwater. Pomacea maculata juveniles fed on rice seedlings at the highest rate at temperatures above 27 & DEG;C. These results suggest that P. maculata becomes a serious rice pest in temperate region as P. canaliculata once it is introduced from warmer regions under global warming. Further biological examination of P. maculata is needed to evaluate the risk of this snail in detail.
