Abstract

Tests were conducted in this study on the slug Limax flavus to determine it glucose has an effect on their feeding behavior. Slugs were given a feeding test to find the duration of fasting tnat would produce the optimal food consumption. The optimal consumption was found in 14-day-fasted slugs. Glucose levels of the 14-day-fasted and fed siugs were then found to be 7.3 mg/100 mL and 31.4 mg/100 mL, respectively. Injections were then made in the 14-day-fasted slugs to bring their glucose level up to the glucose level of a fed slug. Slugs that were injected with glucose showed a feeding response resembling that of a fed slug. Control iniections of mannitol were also given to see how osmotic effects alter the feeding behavior. Osmotic changes did not seem to alter the feeding behavior.
