C. curvignathus feed on dead material, generally in the form of wood, leaf litter or soil and about 10% of the 4,000 odd species are economically important as pests which can cause serious structural damage to buildings, crops or plantation forests. In rubber industry, C. curvignathus attack both earlier stage and mature trees which will reduce the yield can cause profit loss to the industry. In this study, termiticidal activities of Carica papaya and Piper betle methanolic and aqueous leaves extract were evaluated against C. curvignathus. Five different concentrations (20,000 ppm, 40,000 ppm, 60,000 ppm, 80,000 ppm, 100,000 ppm) for each extracts were tested. The mortality rates were recorded every 4 hours for 12 hours. The study revealed that both Carica papaya and Piper betle methanolic and aqueous leaves extracts shows termiticidal activities. After 12 hours, Carica papaya methanolic leaves extract shows better termiticidal activities compared to Carica papaya aqueous leaves extract. 100% mortality rate recorded for each concentration of Carica papaya methanolic leaves extract as the active compound such as terpenoids, tannins, flavonoids and alkaloids were present in the extracts. While the control treatment only shows 13% mortality rate. As for Carica papaya aqueous leaves extract, the highest mortality rate is at 60,000 ppm (20%) and the lowest mortality rate is at 100,000 ppm (7%). However, there is no significant different in the mortality rate for each concentration for Carica papaya aqueous leaves extract. For Piper betle leaves extracts, methanolic extracts shows potential termiticidal activities where 100% mortality rate were recorded for 20,000ppm, 60,000ppm, 80,000ppm and 100,000ppm concentration after 12 hours. While, the highest mortality rate recorded for Piper betle aqueous leaves extracts were recorded at 100,000ppm with 57%. The mortality rate at 100,000ppm shows significant different compared to others treatment. The phytochemical screening indicated the present of terpenoids, tannins, flavonoids and alkaloids in Piper betle methanolic leaves extract which contribute to the termiticidal activities. Carica papaya and Piper betle methanolic leaves extract were analyse using probit analysis to determine lethal concentration in controlling 50% of C. curvignathus. In controlling 50% of C. curvignathus, it is suggested to apply 3,548ppm of Carica papaya methanolic leaves extract and 20,995ppm of Piper betle methanolic leaves extract. The result revealed that Carica papaya and Piper betle have potential to act as a bio pesticides on controlling of C. curvignathus in plantation. Application of bio pesticides can help in protected the environment, human health and thus reducing the management cost.
