Abstract: The Indian white termites are one of the most devastating insects and severely damage to agricultural crop and wooden structure. The chemical pesticides are not safe and crucial impact on environment. Therefore, the bio-efficacy of termiticidal potential of methanol and aqueous leaves extract of Ricinus communis Linn. Were studied against Indian white termites, Odontotermes obesus. The plant leaves were dried, powdered and extracted with methanol and aqueous solvent in soxhlet apparatus for 24 hrs. The 20 termites were exposed to various concentrations of methanol leaves extracts (7.5 8.0, 8.5, 9.0, and 9.5 mg/ml) and aqueous leaves extracts (10.0, 10.5, 11.0, 11.5, and 12.5 mg/ml) of Ricinus communis and percent mortality were recorded after 24 hrs. The termiticidal activity of leaves extract of Ricinus communis were (LC 10= 7.5370 mg/ml, LD50= 8.6238, LC90=9.8679 mg/ml) in methanol and (LC10= 10.016, LC50= 11.355, LC90=12.662 mg/ml) in aqueous solvent respectively. Results revealed that the mortality was increased with increasing in concentration of the plant extracts.The methanol extract of Ricinus communis showed termiticidal potential against Odontotermes obesus, (LD50: 8.6238 mg/ml). The statistical analysis, variance, 95% confidence intervals, and regression equations to support these findings.
