Abstract: BALTAZAR, ALCONA MAE P. Botanical control of termites (Coptotermes vastator Light) using extracts of onion bulb (Allium cepa L.), garlic bulb (Allium sativum L.) and neem leaves (Azadirachta indica A.Juss.). Undergraduate Thesis. Bachelor of Science in Biology, Major in General Biology, Cavite State University, Indang, Cavite. Adviser: Dr. Josefina R. Rint This study was conducted to identify the combination of onion bulb, garlic bulb and neem leaves that would efficiently bring maximum effect against termites; assess the effects of the combined extracts against termites as a stomach and contact poison; assess the relation of termiticidal plant concentrations on weight of treated coconut wood and to assess counts of alive termites; and determine the effect of termiticidal plant concentrations on weight of treated coconut wood before and after termite feeding. Onion bulb, garlic bulb and neem leaf extracts were combined and tested in this experiment with positive (commercial termiticide) and negative (water) control set-ups. Using the mixtures of onion and garlic extracts at 75% concentration as a stomach poison appeared to have the most effective result against termites in terms of percent mortality with 88.16 percent and 8.51 percent of live termites attracted to it after one day of termite feeding. On the other hand, using the onion and garlic extract mixture and garlic and neem extract mixture as a contact poison showed that it is as effective as commercial termiticide with 100 percent termite mortality after one day. Results also showed that wood weight after termite feeding is highly correlated with termiticidal plant concentration. Counts of live termites is also correlated with the level of concentration with 0.04 level of significance which implies moderate correlation between them.
