Abstract
CLARO, LEAH A. (2023). Organic Insecticides for the Control of Bitter gourd fruitfly (Bactrocera sp.). Bachelor of Science in Agriculture Major in Crop Protection- Entomology. Don Mariano Marcos Memorial State University, North La Union Campus, College of Agriculture, Crop Protection Department, Bacnotan, La Union. Adviser: Masanit, Jay Ron A., BSc. Bitter gourd is locally known as “Ampalaya” in the Philippines, a valuable plant, belongs to the Cucurbitaceae family and one of the insect pest that occurs in bitter gourd is the fruitfly in the family Tephritidae are high-profile. Organic insecticides are non- chemical insecticides in controlling bitter gourd fruitfly; hence, this study was conducted to evaluate the effectiveness of organic insecticides for the control of bitter gourd fruitflies. Results of the Bioassay test revealed that two botanical insecticides such as sambong and neem was comparably effective as synthetic insecticide. The mean percentage of mortality on bitter gourd fruitflies, spraying of sambong and neem were able to cause insect mortality with the ranged mean from 80.00 % to 83.33% as compared to synthetic insecticide with a mean of 100.00 %. Among the botanicals, bitter gourd plant sprayed with sambong had the highest net income of (890.3%) per hectare. The application of neem and sambong had produced the highest fruit yield from 1562.4 to 1,765.8 kg/ha as compared to synthetic insecticide with 1,950.3. It is recommended that similar study should be conducted with some other modification of botanical insecticides.
