Anti-termite efficacy of Capparis decidua and its combinatorial mixtures for the control of Indian white termite Odontotermes obesus (Isoptera: Odontotermitidae) in Indian soil

Capparis deciduas and its combinatorial mixtures were evaluated to observe the anti-termite efficacy against Indian white termite Odontotermes obesus. These have shown very high termiticidal activity and wood protection in the soil. It is proved by very low LD50 values i.e. 0.0218mg/g and 0.021mg/g obtained in stem fractions CDS3 and CDS7 respectively. When other ingredients, were used to prepare combined mixtures with C. decidua these have shown synergistic action and caused very high termite mortality in termites. Besides this, both tag binding and wood seasoning experiments significantly cut down (p 0.05 and 0.01 level) in termite infestation in garden saplings and in seasoned dry wood planted in the garden soil. Above treatments have successfully obstructed the ascending and descending movements of termites and prohibited mud plastering and tunnel formation in workers. It was found statistically significant at the level 0.05.
