Abstract
Endosulfan (Thiodan 35 EC) is an organochlorine, cyclodiene insecticide, [6,7,8,9,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9,-methano-2,4,3-benzodioxathiepine-3-oxide (Rao and MUrty 1982)], which is currently registered for use on coffee in Jamaica to control the coffee pest, Hypothenemus hampei Ferrari (Pesticide Control Authority, Jamaica - Personal Communication). It is known to have entered several Jamaican rivers and streams through run off from coffee farms (Mansingh et al. 1995). Endosulfan is recorded as having adverse effects on the density, growth and reproduction of aquatic organisms (IPCS 1984; Muirhead-Thomson 1987; Hassal 1990; Naqvi and Vaishnavi 1993; Raloff 1998). Two prosobranch snails, Melanoides tuberculata and Thiara granifera (Family : Thiariade) are common in Jamaican rivers, streams and ponds. Both species are parthenogenetic and viviparous (Beery and Kadri 1974; Dudgeon 1986), and both are introduced into Jamaica. Both species are readily available, easy to rear under laboratory conditions and can tolerate frequent handling. Very little information is available on the toxicity of endosulfan to snails (IPCS 1984; Muirhead-Thomson 1987). This study investigated the impact of sub-lethal concentrations of endosulfan on growth and fecundity of Melanoides tuberculata and Thiara granifera under laboratory and field conditions.....
