【 摘 要 】

:This study aimed to test the efficiency of plant extracts, metaldehyde and saline solutions, as alternatives to the population control of the snail Bradybaena similaris ,and to investigate the effect of the plant extracts in reducing the damage of the snail on Brassica oleracea . The experiments were performed at the Entomology Laboratory of the Universidade Comunitária da Região de Chapecó (Unochapecó), using a random experimental design with nine treatments in triplicate. Five adult individuals of B. similariswere subjected to each trial, totaling 135 snails. The following treatments were tested: cinnamon ( Melia azedarach ), timbó ( Ateleia glazioveana ), rosemary ( Rosmarinus officinalis ), mate herb ( Ilex paraguariensis ), two concentrations of metaldehyde (3% and 5%), two concentrations of salt solution (5% and 10 %), and a control treatment (distilled water). To evaluate the survival of B. similarisit was checked the treatments every 24 hours, over four consecutive days. The results revealed that the two concentrations of metaldehyde were fully efficient, that the saline solution (10%) had and intermediate efficiency, and that all other treatments were not effective. The treatment with theM. azedarachextract induced a higher consumption ofB. oleracea , while the saline solution at 10% and the extracts ofR. officinalisand I. paraguariensisinhibited leaf consumption.
