Research Description Botanical insecticides are naturally occurring chemicals extracted from plants. Their use for pest management has long been regarded as attractive alternative to synthetic chemical insecticides because of little threat to the environment or to human health. One of the best sources of botanical insecticides is from agricultural waste products or residues from various farming operations (e.g. seeds and peelings). However, most of the studies conducted in the Philippines to isolate and tests biologically active component from plants were preliminary in nature and often dealt with control of agricultural or crop pests. An unexplored application of botanical insecticides in the Philippines is the control of destructive subterranean termites. This project will study the feasibility of using agricultural waste products as botanical insecticides against economically important subterranean termites of the Philippines. Bioactive components will be extracted from seeds or peelings of five (5) fruit crops, viz., atis (Anonna squamosa L.), guyabano (A. muricata L), lanzones (L. domesticum Correa), santol (Sandoricum koetjape) and sampaloc (Tamarindus indica L.) using water or organic solvents. The efficacy selected crude extracts as soil toxicant, repellent or anti-feedant will be evaluated against destructive subterranean termites common in the Philippines. The bioactive components of effective plant extracts will later be identified using gas chromatography-mass spectroscopy (GC-MS).
Research Objectives This study will investigate the potential of selected agricultural residues as sources of botanical insecticides to control economically important subterranean termites of the Philippines. It will extract bioactive components from seeds and peelings of five (5) fruit crops and test their efficacy in contact toxicity and feeding bioassay against destructive subterranean termites of the Philippines. Data will be analyzed using probit analysis and effective concentrations of plant extract sufficient to kill termites be contact or ingestion, trends in mortality and relative toxicities will be determined.
