Background:
Termites are destructive organisms that causes damages on forestry, housing, agriculture and construction. They are mostly controlled with the use of chemical substance known as insecticides which are harmful to human beings. Terminalia catappa and Terminalia ivorensis are plant materials used in folk medicine to exert termiticidal effects.
Objectives:
This study evaluated termiticidal activities of the individual extracts and the synergistic effects of ethanol extracts of Terminalia catappa and Terminalia ivorensis stem bark.
Methods:
The extracts were subjected to phytochemical analysis using standard methods. The termiticidal activities of the extracts were evaluated using immobilization time and death rate. All data were analyzed using GraphPad Prism version 5 software. P<0.05 indicates statistical difference between compared data.
Results:
Phytochemical analysis revealed the presence of saponins, tannins, flavonoids, steroids, terpenoids, alkaloids and cardiac glycosides. The individual extracts and the combination significantly (**P < 0.01) increased the immobilization time and the death rate at 250mg/ml and 500mg/ml compared to the control group.
Conclusion:
Hence, this study confirmed the potency of Terminalia catappa and Terminalia ivorensis against destructive activities of the termites.
