REVIEW OF RELATED LITERATURE AND STUDIES
A. CONCEPTUAL LITERATURE
Many attempts have been made to produce an insect repellent from Lanzones peelings. Lanzones peelings are the main ingredient for our study. The group chose it because according to research, the skin of lanzones has a certain compound that can repel mosquitos. When burned, it also produces an aromatic smell which is soothing and relaxing. This ingredient can also be burned easily. It is perfect for the production of katol, a coil of incense used to kill and repel mosquitoes here in the Philippines. It is more effective when lanzones peelings are dried first under the sun so it will be more combustible. When combined with starch, the group will be able to produce a mosquito coil quite similar to those on the market. The only difference is that our group will be making an insect repellent in the form of a candle.
Lansium domesticum, also known as langsat, buahluku or lanzones, is a species of tree in the Mahogany family. The plant, which originates from western Southeast Asia, bears edible fruit. It is the provincial flower for the Indonesian province of South Sumatra. The tree is average sized, reaching 30 meters (98 ft) in height and 75 centimeters (30 in) in diameter. Seedling trees 30 years old planted at 8 x 8 meter spacing can have a height of 10 meters and diameter of 25 cm. The trunk grows in an irregular manner, with its buttress roots showing above ground. The tree's bark is a greyish color, with light and dark spots. Its resin is thick and milk colored.
An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. There are also insect repellent products available based on sound productions, particularly ultrasound (inaudibly high frequency sounds). These electronic devices have been shown to have no effect as a mosquito repellent by studies done by the EPA
