Mortality Rate of Termites
Sprayed With Yemane Decoction and Chili Extract
Chapter 1 – Introduction
Background of the Study
Using natural pest and disease control is often cheaper than applying chemical pesticides because products and materials which are already in the home and around the farm are most often used. Termites are small, white, tan or black insects. It belongs to the insect order Isoptera, an ancient insect group that dates back more than 100 million years. Termites also known as white ants a misnomer based on superficial similarities in the appearance and habits to these two insects group. Termites can cause severe destruction to wooden structures and also consume structural lumber. They considered pest attacking the kept documents. They feed on dead organic material such as crop residues, mulches and soil organic matter (humus). However when this type of food is not available they will eat live plant material including crops such as groundnuts, millets and maize. Yemane(Gmelina Arborea Roxb) from family Verbenacea is a tropical evergreen, perennial tree up to 40m tall and 140 cm in diameter, but usually smaller than this. It is also considered as toxic or poisonous tree which aid as pest repellent. Gmelina Arborea Roxb gained prominence not only in the Philippines but also in neighboring Asian countries because of economic importance. It is raw material for pulp and paper making post, house, timber and poles while rotary cut veneers are utilized for plywood. The leaves used as feeds for goats and cattle. The roots and bark are stomachic, galactogogue laxative anthelmenthic, improve appetite, burning sensations, fevers and urinary discharge. Chili peppers have been a part of the human diet. Christopher Columbus was one of the first Europeans to encounter them (in the Caribbean), and called them "peppers" because they, like black and white pepper of the Piper genus known in Europe, have a spicy hot taste unlike other foodstuffs. Upon their introduction into Europe chilis were grown as botanical curiosities in the gardens of Spanish and Portuguese monasteries. But the monks experimented with the chilis' culinary potential and discovered that their pungency offered a substitute for black peppercorns, which at the time were so costly that they were used as legal currency in some countries. Peppers and certain herbs contain the compound "capasaicin" which will irritate and repel many insects. Chili peppers are very strong and insects (as well as other animals) have a very powerful sense of smell and taste. The chili works to basically fry their senses and causes them pain.
The study focused on the “Mortality Rate of Termites Sprayed with Yemane Decoction and Chili Extract” with an objective:
To determine the mortality rate of termites sprayed with yemane decoction and chili extract.
Statement of the Problem:
At present, termites were considered as pest as they cause severe destruction to a wooden structure. This study focused on the organic preparation of Yemane decoction and chilli extract as substitute to a synthetic pesticide in controlling against termites.
This study sought to answer the question:
What is the mortality rate of termites sprayed with yemane decoction and chili extract? Null Hypothesis
There is no significant difference among the mortality rate of termites sprayed with yemane decoction and chili extract. Significance of the study:
This study would give an idea and sufficient information among lumber users and furniture operators, specifically to the teachers having a problem against those termites attacking their classrooms. Furthermore, it would serve as a guide to people who lack knowledge on the botanical preparations to control termites. They would be benefited with the outcome of the study and at the same time they would be informed that Yemane decoction and chilli extract serve as substitute to synthetic pesticides in controlling...
