Abstract

Golden apple snail (GAS; Pomacea canaliculata) is a member of the genus for freshwater snails with gill and operculum. It is an aquatic gastropod mollusc in the family Ampullariidae. This species has been introduced outside its native South American region and considered invasive because of its voracious appetite for paddy and other plants. In this study, the effect of bioresources and commercial waste were experimented to determine their effects on GAS. Garlic (Allium sativum) skins, groundnut (Arachis hypogaea) shells, used coffee (Coffea liberica) grounds and water spinach (Ipomoea aquatica) stems were extracted at 100 °C in aqueous system. The potential of these aqueous extracts as nanobiocontrol were investigated through the characterisation of particle size and molluscicidal activity. The results indicated that the aqueous extracts from water spinach (Ipomoea aquatica) in the form of nanoparticle (780.93 ± 2.45 nm) showed more lethal effect on GAS after 5 ± 1 min of exposure compared to used coffee grounds nanoparticle aqueous extract (553.64 ± 1.32 nm) at 45 ± 15 min, garlic skin aqueous extract (1381.34 ± 7.15 nm) at 8 ± 1 min and ground skin aqueous extract (1114.39 ± 10.35 nm) at 7 ± 2 min, respectively. These organic materials have the potential to be developed as biocontrol of GAS.
