This study entitled “ Insecticidal Potential of Seed Extract of Selected Botanicals Against Coffee Bean Weevil (Araecerus fasciculatus de Geer) was conducted at the Crop Protection Research Laboratory of the Research Center, Cavite State University, Indang, Cavite from June 2005 to January 2006. Specifically, the study aimed to: (1) evaluate the insecticidal effectiveness of seed extract of selected botanicals in repelling coffee bean weevil; (2) determine the most effective seed extract of selected botanicals in repelling coffee bean weevil; (3) evaluate the toxicity of produced insecticide against coffee bean weevil; (4) determine the most toxic seed extract of different botanical pesticides against coffee bean weevil; (5) evaluate the effect of different concentrations of the most effective botanical pesticides from experiment 1 and 2 against coffee bean weevil; and (6) determine which concentration was the most effective against coffee bean weevil.
The study focused mainly on testing the insecticidal potential of seed extract of selected botanicals. The botanicals were evaluated using three experiments namely:
Efficacy test/Repellant test, Toxicity test, and Dilution test. In the first and second experiment, there were four treatments each replicated three times. The treatments were as follows: T; (control-cymbush); T (pure sour sop seed extract); T3 (pure papaya seed extract); and T, (pure lantana seed extract). While in the third experiment (dilution test), five concentrations of the best botanical (lantana) replicated three times were prepared.
The treatments were: T; (10% lantana seed extract + 90% water); T> (20% lantana extract +80% water): T3 (30% lantana seed extract + 70% water); Ts (40% lantana seed extract +60% water); and Ts (50% lantana seed extract + 50% water).
Results of the first and second experiment showed that lantana was the most effective among the three botanical pesticides used. The third experiment showed that the higher the concentration of lantana (50% lantana seed extract + 50% distilled water), the more effective it is in controlling coffee bean weevil.
