The golden apple snail, Pomacea canaliculata is an invasive alien pest that seriously affects rice cultivation in many Asian countries.

These freshwater molluscs devour young rice seedlings, causing extensive damage to both transplanted and direct seed.

Most Asian farmers resort to short-term solutions by using molluscicides that have negative impacts on non-target organisms, aquatic biodiversity, and the environment.

Due to the toxic hazards of the synthetic insecticides, biological control through botanical pesticides are the best alternative for reducing the golden apple snails damage in paddy fields.

Neem or also known as Azadiractha indica is the botanical insecticide and was formulated as extract.

The objective of this research is to determine effective plant parts of neem as biopesticide on controlling GAS.

Toxicity of the neem was tested on the and the mortality of snails was observed every 12 hours to 48 hours.

The study showed that seeds extract concentrations at 100 g/100 ml hot water give the higher efficient toxicity with 97% of GAS were killed at 48 hours.

Mean for all treatment with neem extract leaves showed less efficient compared with seeds extract.

Otherwise, seeds extract using hot water solvent give the highest mortality for GAS
