Attractant Food Pellets Containing Molluscicides Against the Fresh Water Snail Indoplanorbis exustus

Fascioliasis is an important helminth disease caused by Fasciola gigantica. The snail control is one of the important methods in the campaign to reduce the incidence of fascioliasis. The order to achieve this objective, using of bait formulations containing an attractant and molluscicides is an appropriate approach to lure the target snail population to the molluscicides. In the present study snails attractant food pellets (SAP) were prepared from 20 mM carbohydrate in 2% agar solution. Attraction of snails to different bait formulation (carbohydrate + molluscicides) was carried out in glass aquaria having diameter of 30 cm. Among all the bait formulations containing molluscicides, limonene, attract 34.04% of snail after 2 hours, which was significantly different from their control. Bait containing ferulic acid emerged as the strongest bait formulation (LC 96 h, 1.229 %) against Indoplanorbis exustus. 50
