| Abstract: | When the freshwater snail Lymnaea acuminata was exposed to sub-lethal doses (2.0, 5.0, and 8.0 mg/L) of carbaryl, fecundity was significantly reduced and even stopped at higher sub-lethal doses and altered metabolic activity in the body tissue of the snail was observed. The change from aerobic to anaerobic metabolism results in lesser energy production in the body tissues of the snails, causing paralysis and finally death. This reduced fecundity and altered metabolism suggests that it would be better to avoid the use of carbaryl pesticides in the water bodies or fields adjoining the water bodies particularly in the rainy season. |
