CERCARIAE INFECTION RATE IN ALL COLLECTED SNAIL SPECIES IN THE RESEARCH RICE FIELD
Main Article Content
Abstract
Tan Thanh district, the largest rice cultivation area in Long An province, was the focus of a study on snail species diversity and trematode infection rates in rice fields. The research identified 13 snail species from 11 genera and 7 families in the communes of Kien Binh, Nhon Ninh, and Tay Ninh. The Golden apple snail (Pomacea canaliculata) was the most abundant species, accounting for 33.1% of the collected specimens. The other 12 species included Filopaludina sumatrensis (18.07%), Filopaludina martensi martensi (9.32%), Idiopoma umbilicata (1.52%), Sinotaia lithophaga (0.48%), Cipangopaludina lecythoides (0.39%), Bithynia siamensis (27.26%), Clea helena (0.30%), Gyraulus convexiusculus (0.04%), Indoplanorbis exustus (0.04%), Melanoides tuberculata (0.65%), Lymnaea viridis (0.09%), and Pomacea bridgesi (8.71%). The Golden apple snail was cercariae free (0.00%) while two snail species, Bithynia siamensis and Filopaludina sumatrensis, were infected with trematodes at rates of 5.1% and 0.9%, respectively. Trematode infection rate in the wet season were higher during the wet season than the dry season. Three Cercariae morphotypes were identified: Xiphidio, Furcocercous, and Echinostome Cercariae. This study provides valuable data on snail species distribution and trematode infection in rice fields, contributing to disease management, food safety, and improved rice yield.
