Resumen:
Pollutants as well as starvation usually modify homeostasis of neutral lipids in aquatic organisms. However, studies about the simultaneous effects of both stressors are scarce. The aim of this study was to evaluate the effect of toxicant exposition under starvation on neutral lipids of freshwater snail Pomacea canaliculata, selected as the model organism. Adult male snails were exposed to sublethal concentration of the pesticide cypermethrin (100 µg/L) during 4 and 10 days under starvation condition. Fed and starved control snails with and without solvent were also included. Total lipid content, neutral lipid classes, fatty acid composition, and pesticide accumulation were studied in digestive gland of snails. The concentration of ethanol used as the pesticide vehicle would not be an additional stressful agent. As expected, starvation caused a decrease in neutral lipid content in digestive gland of snails with respect to those fed ones (p
