Abstract: HINGADA, JAY LORENZ J. Pesticidal Potential of Selected Botanicals Against Rice Weevils (Sitophilus oryzae L.), Coleoptera:Curculionidae. Undergraduate Thesis. Bachelor of Science in Agriculture. Cavite State University, Indang Cavite. May 2017. Adviser: Dr. Evelyn O. Singson. The study was conducted from January to April 2017 at Caute State University to evaluate the toxicity, antifeedant, and anti-oviposition effects of selected botanicals against rice weevil using rice grains. Adult rice weevil were exposed on rice grains with different plant powders. The result showed that Lantana camara obtained the highest mean mortality of 93.33% at 21 days after treatment (DAT) followed by Chromolaena odorata showed 75.84%, Ageratum conyzoides (74.17 %), Mikania micrantha (70.84%) and Tithonia divers (folia (68.33 %) mortality. A. conyzoides and C. odorata were found to be effective in deterring feeding of rice weevil on rice grains and in reducing the adult emergence, respectively. It was proved that the longer the rice weevils were exposed to L. camara the higher the mortality will be. This study concluded that all botanicals can be used to control the infestation of S. oryzae. Overall, the botanical plant that the greatest potential for the control of rice weevil was Lantana camara.
