Feeding of bait containing attractant and sublethal dose of different molluscicide on the reproduction of snail Indoplanorbis exustus
Journal Title: European Journal of Biological Research - Year 2016, Vol 6, Issue 1
Abstract
The snail control is one of the important methods in the campaign to reduce the incidence of fasciolosis. In order to achieve this objective, the method of bait formulation containing an attractant and molluscicide is an appropriate approach to lure the snail to the molluscicide. The present study was to observe the effects of sublethal (60% of 24h LC50) feeding of active molluscicide ferulic acid, umbelliferone, eugenol and limonene in bait containing attractant carbohydrate (starch, maltose) on the, fecundity, hatchability and survival of snail Indoplanorbis exustus. Bait containing attractant carbohydrate and molluscicides significantly reduced the reproductive capacity of the snail Indoplanorbis exustus. Maximum reduction in fecundity (50.64 % of control) was observed in snail fed to starch + eugenol. In withdrawal group significant recovery was noted in all bait fed snails (90.71 % of control). The hatching period of egg laid by treated group was prolonged from 11 to 19 days with respect to 10 to 13 days in control snails. Percent hatchability as well as survivability of young snail were significantly reduced in bait fed snails.
