Biopesticidal Control of Storage Insect Pest Caryedon Serratus OL.

Botanical extracts of Acorus calamus L. and Adhatoda vasica Nees. (concentrations used 1%, 0.5% and 0.25%) as well as commercial preparations of Azadirachta indica (Neem) viz. neem oil based Multineem 0.03% EC (concentrations used 0.015%, 0.0075% and 0.00375%) and neem seed kernel based Neemarin 0.15% EC (concentrations used 0.075%, 0.0375% and 0.01875%) were tested against the pest. Tests were carried out on Acacia nilotica seeds with freshly laid eggs, freshly hatched eggs and on treated seeds onto which freshly emerged beetles were released. A. calamus showed the best ovicidal and larvicidal activity causing 100 per cent mortality. It also acted as the best oviposition deterrent. Rest of the botanicals showed more or less similar activities.
