REVIEW OF RELATED LITERATURE
This chapter presents the available literature and studies conducted that are crucial to the investigation of researchers in Pediculicide activity of Premna odorata leaves against Lipeurus caponis.
The Plant Material
The plant sample, Premna odorata Blanco (“Alagaw” in Filipino) is from the family of Verbenaceae/Lamiaceae genus Premna. It is also known as Alagau (Tagalog), Abgau (Bisaya), Fragrant premna (English), Saliargo (Central Bisaya). Alagaw can be found in the secondary forests in the Philippines and abundant in a low-altitude thicket (Giltendez, 2015).

It is also known by a few other scientific names such as Premna curranii H., Premna oblongata (Quisumbing, 1978). Alagaw is a small hairy tree 3 to 8 meters high, the leaves are ovate to broadly ovate, 10 to 20 centimeters long, with a broad, rounded, or somewhat heart-shaped base, and pointed tips, under the surface of the blade is usually covered with short hairs, aromatic when crushed, flowers are greenish-white or nearly white, 4 to 5 millimeters long and borne on terminal inflorescences (cymes) 8 to 20 centimeters in diameter, the fruit is fleshy, dark purple, rounded, about 5 millimeters in diameter (Stuart, 2016).

In the Philippines, a decoction of the leaves of alagaw is used for loosening phlegm and as a cough remedy. The timber is sometimes used if trees have reached larger dimensions. They are also used in hedges, occasionally also as ornamentals. Ripe fruits and cooked leaves are occasionally eaten.
Importance of Chickens
Poultry provides humans with companionship, food, and fiber in the form of eggs, meat and feathers (Darre, 2011). Chicken meat and eggs are the best source of protein and are badly needed by the many millions of people who live in poverty. It is providing not only high-quality protein but also important vitamins and minerals. A major advantage of eggs and poultry meat as human food is that there are no major taboos on their consumption. In addition, a chicken provides a meal for the average family without the need for a refrigerator to store left-overs (Farrell. 2014).
