INSECT REPELLENT AND INSECTICIDAL ACTIVITY OF DIFFERENT DEVELOPMENTAL GROWTH STAGES OF POD AND STEM BARK EXTRACT OF CASSIA FISTULA L. AGAINST TRIBOLIUM CASTANEUM
Satpute S. M.* and Gaikwad D. K.
Insect repellent and insecticidal activity was evaluated from different developmental growth stages of Cassia fistula pod and stem bark extracts on adult red flour beetle Tribolium castaneum. Acetone extract of all the samples tested have shown insect repellent and insecticidal activity compare to control and standards tested. Samples aqueous old stembark, benzene old stembark and ethanolic young stembark extract have shown most promising insect repellent and insecticidal activity compare to other samples tested. Samples Benzene one month and ethanolic 4 month extract have shown good (More than 50%) repellent activity while samples aqueous one month, aqueous pulp, aqueous young stembark and Benzene 1 month showed good (more than 50%) insecticidal activity compare to other samples tested. From the results it confirmed that samples Aqueous old stembark, Benzene old stembark and ethanolic young stembark have shown significant (p<0.01) activity.
Keywords: Cassia fistula, Extracts, insect repellent activity, insecticides, insecticidal activity.
