Scholarcy highlights

  • The golden apple snail, Pomacea canaliculata is a freshwater snail native to tropical and subtropical South America
  • The species was introduced into Korea as a human food source in 1983 and was first applied as a weed control agent for the paddy fields in 1992
  • As the snail is well known as an environmentally friendly biological control agent for weeds, the area of cultivation in which the golden apple snail is used for biological control has been enlarged substantially each year
  • We determined the status of the overwintering golden apple snail based on a literature survey and investigated the potential distribution area of the snail, as a result from global warming in Korea
  • The potential distribution area of the overwintering golden apple snail would be enlarged under the influence of global warming; ranging from 45.5% of South Korea‚Äôs land area in the 2020s to 88.4% in the 2080s
  • When the golden apple snail was first used for weed control in paddy fields, it was considered unable to overwinter in Korea because it originated from a tropical area
  • The samples reported in the literature were collected primarily in irrigation canals and ditches near paddy fields in conjunction with research on the use of the golden apple snail in environmentally friendly farming
