Applied Research II] (General Science Curriculum) Cavite State University Science High School, Indang, Cavite, March 2006 “Evaluation Of Different Botanical Pesticides Against Pachyrrhynchid Beetle Infesting Liberica Coffee.” Adviser: Dr. Teddy F. Tepora. A study entitled “Evaluation of Different Botanical Pesticides Against Pachyrrhynchid Beetle Infesting Liberica Coffee” was conducted at the Central Experiment Station of the Research Center and Crop Protection Laboratory at Cavite State University, Indang Cavite from January 2005 to March 2006. The general objective of the study was to prevent, destroy, repel or mitigate Pachyrrhynchid beetle infesting Liberica coffee. Specifically, the study aimed to (1) evaluate the effect of different botanical pesticides against Pachyrrhynchid beetle in the nursery; (2) evaluate the toxicity of different botanical pesticides against Pachyrrhynchid beetle in the laboratory; (3) determine the most effective botanical in controlling. Pachyrrhynchid beetle; and (4) determine the most effective concentration of the most effective botanical that will be best for controlling Pachyrrhynchid beetle. The study focused on the evaluation of different botanical pesticides. The botanicals were evaluated in three series of experiments, namely: efficacy test, toxicity test and dilution test. In the first and second experiments, five treatments of botanicals and three replications per treatment were prepared. The treatments were: (1) T1 (control)- cymbush; (2) T2- wild sunflower; (3) T3- sapinit; (4) T4- madre de cacao; and (5) TS-neem. While in the third experiment, five concentrations of the best botanical (wild sunflower) and three replications per treatment were prepared. (1) T; (10% pure extract of wild sunflower + 90% water); (2) Tz (20% pure extract of wild sunflower + 80% water); (3) T3 (30% pure extract of wild sunflower + 70% water); (4) Ty (40% pure extract of wild sunflower + 60% water); and (5) Ts (50% pure extract of wild sunflower + 50% water). Four different botanicals namely: wild sunflower (Tithonia diversifolia Helms L.), sapinit (Lantana Camara L.), madre de cacao (Gliricidia sepium) and neem tree (Azadirachta indica), and commercial pesticide, cymbush, were used as raw materials. The botanicals were chopped, pounded, extracted and strained. The extracts of the botanicals were applied to the treatments of the first two experiments: efficacy test and toxicity test. While the extract of the best botanical in the first and second experiments were used in the third experiment (dilution test) with different concentrations. Among the botanicals used, wild sunflower (Tithonia diversifolia Helms L.) was the most effective in terms of preventing Pachyrrhynchid beetle in infesting Liberica seedlings in the nursery (efficacy test). While in the first test in the laboratory (toxicity test), the most effective in terms of killing the Pachyrrhynchid beetle was the wild sunflower. While in the second test in the laboratory (dilution test), the most effective concentration of wild sunflower in killing the Pachyrrhynchid beetle was T; (50% pure extract of wild sunflower + 50% water).
