abstract
The studies on the efficacy of plant and animal origin bio-products on major stored pest of Rice (Oryza sativa L.) viz. Rice weevil (Sitophilus oryzae) were carried out to know the impact of above bio-products on percent weight loss and percent mortality .This experiment was conducted under Complete Randomized Design(CRD). Among the treatments with botanicals the orientation of Sitophilus oryzae was recorded highest in Control and least no of adults were oriented towards Lantana camara (0.33), minimum percent weight loss was observed with Neem leaf powder (10.67%) as compared to coragen (0.00%), maximum mortality rate was observed when rice was treated with Neem leaf powder (90.00%) and Lantana camara leaf powder (90.00%). Percent mortality rate (hours from treatment) of smoke, in this case maximum was observed with the rice treated using Neem (semi-dried) leaves smoke (48.33%). Therefore, the present laboratory studies clearly showed the efficacy of plant and animal origin bio-products on major stored pest of Rice (Oryza sativa L.) were almost as effective when compared with Coragen (Insecticide) .Hence it may be concluded that these plant and animal bio-products are eco-friendly, cost effective and easily available. It can easily be incorporated for the easy management of stored pest in paddy.
