Coptotermesvastator or Philippine milk termitesare social insectsthat raise their young as a group of workers, soldiers and reproductive queen and king. They cause significant losses to annual and perennial crops and damage to wooden components in buildings. Owing to their wood-eating habits, they destroy the livelihood of tropical farmers and literally eat their way through our homes, because they remain well concealed. Their presence is often undetected until the wood structure is severely damaged from within and shows surface changes.Damage to wooden structures and other cellulosic materials attributed to termites has been estimated to exceed $3 billion annually worldwide.Control of termites is primarily dependent upon continued applications of synthetic pesticides or traditional wood preservatives (Lee and Ryu, 2003).
Several termiticidescontainsactive ingredients such asfipronil, bifenthrin, chlorfenapyr, permethrin, cypermethrinand imidacloprid are registered around the world under various brand names (Verma et al., 2009). Although effective, there are concerns regarding the use of such pesticides leading to environmental pollution and health disorder. Hazards associated with these synthetic chemicals include their persistence in the environment, bioaccumulation potential in the tissues of organisms through the food chain and toxicities for humans and wildlife. They may also be transported over long ranges through rivers and ocean currents, and contaminate regions far from their sources. Reducing pollution has always been important and finding alternative sources to humans. To avoid these problems, there have been efforts to use plant essentialextract as potential alternatives to currently used termite control agents because they constitute a rich source of bioactive chemicals (Park and Shin, 2005; Gilliom et al., 2006).Moreover, they are known to be safe as they are commonly used as fragrances and flavoring agents for foods and beverages (Isman, 2000).
An estimate says that there are about 2500 000 species of higher plants in the world and pharmacological activities of most of them are not studied (Jeevam et al., 2004).The plant leafextract of Manikarazapota Linn. (Chico) is a member of the Sapotaceae family.Fleshy is brown, soft, slightly gritty, sweet, and very agreeable in flavor. In many urban communities burn the dry leaves to repel the mosquitos in the area. Alto this plant are sweet when ripe many insect didn’t attack this plant because of its natural defense to insect. Artemisia vulgaris Linn. (mugwort) is a member of the Asteraceae family. It is a tall (0.8-1.4 m), aromatic, threatened perennial herb distributed throughout the northern temperate regions of Africa, Asia, Europe, India, and North America. Numerous medicinally active components of A. vulgaris have been identified, including coumarins, essential oils, flavonoids, polyacetylenes, sesquiterpene lactones, and sterols (USDA-ARS-NGRL, 2004). This study would like to find out an alternative solution to solve the termite problem Background of the Study
Termites are one of the most damaging insects to wooden structures worldwide. Termites are a serious menace to both plants and structures. They are considered as one ofthe most threateningpest in agriculture and the urban environment.The researcher becamemore interested to conduct a study on the use of plant extract as alternativetermiticide. Based on the researcher’s observation most Filipino used commercial termicidelike solignum and other various chemicals brand name without knowing its harmful effect to human’s health. In one of the article in encyclopedia plants develop their own defense mechanism...
