Potential of Carica papaya and Artocarpus integer Extracts as Botanical Pesticides for Controlling, Golden Apple Snail, Pomacea canaliculata

Abstract

Golden apple snail (GAS), Pomacea canaliculata, is a major pest of paddy in Southeast Asia. Due to serious effects of GAS in rice cultivation, farmers have resorted to use synthetic molluscicides for controlling damages caused by GAS leading to negative impact toward the environment and human health. Accordingly, it is essential to study and develop new botanical pesticides for controlling GAS. The objective of this study is to expose the potential of selected plant extracts using bioassay test and antifeedant activity are that responsible for controlling GAS. Selective of potent extracts from Carica papaya leaves and peels of Artocarpus integer were tested on GAS in laboratory conditions. Five different concentrations of crude extracts were extracted using 95% of methanol and ethanol. Mortality of GAS was observed within 96 h with 24 h nterval. The obtained results from bioassay test show that methanol extracts of C. papaya (LC50 = 18. 5 g/L) gave a higher mortality of GAS compared to A. integer extract (LC50 = 39.8 g/L). High antifeedant activity of GAS imposed by ethanol extracts of A. integer (LC50 = 25.7 g/L) is compared with C. papaya extract (LC50 = 20.6 g/L). Thus, this study showed that extracts of C. papaya are more effective for sustainable control of GAS and extracts of A. integer have a potential use as an antifeedant activity toward GAS.
