Abstract

The Effect of chronic application of sublethal concentration of molluscicides,
bayluscide (0.05 -0.025 ppm) and trifenmorph (0.25 - 0.125 ppm) on the glycogen
and protein content of Biomp < /em>ha/aria alexandrina was determined. Bayluscide and
trifenmorph produced significant reduction in the glycogen content of Biompha/aria
alexandrina, but a significant decrease in the protein content of the snails was not
apparent until after 4 weeks of continuous exposure. The results indicate that the
molluscicides may exert their primary molluscicidal action on the carbohydrate
metabolism of the snails.The both molluscicides significantly reduced the gain in shell diameter of thesnails.
