The study of systematic, physiology, pharmacology and host-parasite relationship is compound by the lack of an efficient, simple and inexpensive method for anesthesia or muscle relaxing of gastropod molluscs.Pan (1958) demonstrated that snail exposition to a menthol solution produce muscle relaxation in pulmonate molluscs, allowing a better tissue fixation aiming histological analysis. Michelson (1958) demonstrated that the best snail distension and immobilization was obtained through the immersion of snail in urethan aqueous solution. This methodology has been largely used in many mollusc species, however the technique does not permit snail manipulation, which demands a complete state of anesthesia. Runhan et al. (1965) concluded that anesthetic or narcotic drugs have a variable effect on mollusc, depending on the mollusc species tested, the drug concentration and the exposition time. Planorbidae molluscs are routinely relaxed by sodium pentobarbital in taxonomical and
