Pesticidal activity of the leaves of Manihot esculenta against the pest Sitophilus oryzae
Mity Thambi, Tom Cherian
Manihot esculenta, Cassava also called, tapioca-root, kappa (predominantly in India) a woody shrub of the Euphorbiaceae family native to South America. In the present study reveals that, plant extracts of Manihot esculenta leaves in ethyl acetate solvent is highly toxic against adults of Sitophilus oryzae. Higher doses and exposure time are required to achieve 100% mortality for the adults of Sitophilus oryzae. The ethyl acetate extract ofManihot esculenta could be used as a potential grain protectant against Sitophilus oryzae. The use of botanical materials as insecticides will benefit our agricultural sector. They are not only of low cost, but have no environmental impact in term of insecticidal hazard. Therefore, the findings of the current experiments strongly support the use and exploration of botanicals in pest management practices.
