SY 2007-2008
The research was presented at the 2007 Regional Science Fair, Life Science Individual- Cluster 1 by Alvier Lopena, in the absence of Aquiles. It won 3rd. This study tested the mollusk-killing activity of aqueous neem (Azadirachta indica) leaf extracts on Pomacea canaliculata, the snail that is infesting on Philippine farmlands. It was so endeavored to help Filipino rice farmers have better harvest by wiping out the kohol population through a simply prepared molluscicidal extract.

It was so endeavored to help Filipino rice farmers have better harvest by wiping out the kohol population through a simply prepared molluscicidal extract. ABSTRACT
The reactions of kuhol or Pomacea canaliculata to the aqueous leaf extracts of neem or Azadirachta indica applications in laboratory conditions were investigated. The reaction referred here to was on the mortality that the extract caused on the said snails. Equal amounts of leaves and water were used to prepare the aqueous extracts, which were grouped into 10 mL and 20 mL treatments. The greatest molluscicidal effect was observed in 20 mL extracts and it was on the small snails that the extract caused the highest mean mortality of 96.7%. The mortalities among small snails applied with different amounts of extracts did not significantly differ, with an F – value of 1.000 whose level of significance was .347. Therefore both extract amounts are molluscicidal to the small snails. A mean mortality of 80.0% was observed on the medium sized snails. The mortalities among medium sized snails differ significantly with varying amounts of extract, with an F – value of 10.139. Therefore, more medium sized snails are killed using 20 mL extract. This project further found out that there was no significant difference in mortalities between the medium and small-sized snails applied with varied amounts of neem leaf extract.
