Abstract

The eftlcacy of four pesticides methomyl, fenltrothlon, bendIocarb and
carbaryl against the land snail, Theba cant/ana (Montagan) was evaluated under
three different exposure periods. Each of the tested pesticides was applied as baits at
three concentrations. Data indicated that aU pesticides presented the highest snail
mortality in the first day of the examination. For the time being, the mortality values
showed a gradual decrease to reach the minmum level on the third and fourth day
after inspection. The snail mortality percentages were directly associated with the
toxicant concentration. It was also clear that methomyl proved to be the most effective
material folCMed by fenltrothion. bendiocarb and carbaryl.
