Abstract :

Rhizopertha domonica is secondary pest of stored grains. Both the adults and grubs cause considerable damage to the grains under storage in tropical and sub-tropical parts including India. Many synthetic organic pesticides are used to control stored grain pest which results in damage to the environment. In the last decade, however, there has been an increasing interest in natural products particularly those of plant origin to control pest species. In view of this, the smoke of different parts of the plants, Peganum harmala. Peganum harmala was used against the Rhizopertha domonica and adult mortality was recorded after 48 hours of exposure. 20 adult insects were subjected to the smoke of various plant parts in chamber specially designed for this purpose. It was observed that the smoke treatement of the leaf of Peganum harmala causes 40-50% mortality in Rhizopertha dominica after 48 hours of treatement.
