THE COMPOSITION OF SNAIL SPECIES AND CERCARIAE IN SNAILS IN RICE FIELD OF CU CHI DISTRICT, HO CHI MINH CITY, VIETNAM
Main Article Content
Abstract
Snail composition in Trung Lap Thuong rice field in Cu Chi district, Ho Chi Minh City was studied in the wet season of 2022 and the dry season of 2023. A total of ten snail species was collected and identified from 922 snail samples by the morphological method including Filopaludina sumatrensis (39.6%), Pomacea canaliculata (35.9%), Filopaludina martensi martensi (17.0%), Cipangopaludina japonica (2.7%), Clea helena (2.2%), Idiopoma umbilicata (1.4%), Melanoides tuberculata (0.7%), Cipangopaludina chinensis (0.3%), Bithynia siamensis (0.1%) and Gyraulus chinensis (0.1%). In which, Melanoides tuberculata, Filopaludina martensi martensi and Cipangopaludina japonica were infected cercariae of trematode with the prevalence of 50.0%, 9.6% and 4.0%, respectively. The groups of cercariae from snails were xiphidio cercariae, furcocercous cercariae and pleurolophocercous cercariae. The research identified the snail composition and cercariae infection in snails in rice field of Cu Chi district to contribute to provide data using for research and teaching.
