These freshwater snail damages devourly by completely eliminating the young leaves and stems of rice seedling from plant bases which resulting in the death of the rice seedlings. Farmers mostly rely on commercial available synthetic molluscicides for immediate control of GAS, without considering the toxic hazards towards themselves and non-target organisms. Botanical pesticides are an excellent alternative to synthetic pesticides as a means to reduce negative impacts to human health and the environment. Botanical pesticides are naturally occurring derived from chemical extracted from potential plants. Potential plants of secondary metabolites have role to protect themselves from pests and diseases due to its chemical compound, which caused mortality to pest, repellency and insect growth regulatory activities. The objective of this research is to quantify an active compound from selected indigenous plants (Carica papaya, Manihot esculenta and Artocarpus integer) and to impetus a potential plant extracts from selected indigenous plants using bioassay and antifeedants test that responsible in controlling GAS. Phytochemical screening using UV spectrophotometric analysis methods were used to detect the active compound in selected plants. From obtained UV spectrophotometric results, total saponins content (12,713 ppm) and total phenolic acid (10,772 ppm) were highly found in methanol extractions of Carica papaya. While, total flavonoids content (7,360 ppm) was highly found in methanol extractions of Artocarpus integer. Mortality and antifeedants test were conducted with five different concentrations ranging from 10,000 to 50,000 ppm. The obtain results from bioassay test shows that methanol extracts of Carica papaya gave a higher mortality towards GAS within 96 hours with LC50 (18,511 ppm), followed in order by methanol extracts of Manihot esculenta (19,517 ppm) and methanol extracts Artocarpus integer (25,715 ppm). High antifeedants activity (AI) of GAS was imposed by methanol extracts of Carica papaya with highest weight loss of GAS (13.91 %) compared with other extracts. While, lowest feeding deterrent index (FDI) was also imposed by methanol extracts of Carica papaya with lowest weight loss of paddy seedlings (42.11%). Mortality of GAS was increased with higher concentrations of plant extracts and exposure time from 24 hours to 96 hours. This research showed that methanol extracts of Carica papaya have higher potential to be used as botanical molluscicides and an as repellent agents for controlling GAS. Therefore, further analyses should be carried out to formulate the botanical molluscicides based from leaves of Carica papaya and test for field testing. 2018 Thesis https://ir.uitm.edu.my/id/eprint/92842/ https://ir.uitm.edu.my/id/eprint/92842/1/92842.pdf text en public masters Universiti Teknologi MARA (UiTM) Faculty of Plantation and Agrotechnology Md.
