CHAPTER 1
THE PROBLEM AND ITS SCOPE
Background of the Study
Statement of the Problem
Generally, this study aims to determine the effectiveness of Kayos (Dioscorea
hispida) on termites.
Specifically, this study will answer the following questions:
1. What is the termiticidal effect of pure Discorea hispida tubers extract on working
termites in terms of mortality rate 24 hours after application?
2. Is there a significant difference on the mortality rate of termites as affected by
Kayos extract, 24 hours after application?
Hypothesis:
There is no significant difference on the mortality rate of termites as affected by
Kayos extract, 24 hours after application.
Conceptual Framework
Mortality Rate of Termites 24

Significance of the Study
The result of this study will be beneficial to the following:
Home owners. The result of this study will give them idea on how to
exterminate termites in their houses that cause a lot of damages especially on their
wood furnitures and books.
Manufacturers. The result of this study can be their basis in creating a
new product that is less in chemical and will help them increase their profit.
Future researchers. This study will help them gain more knowledge and
will lead them for further study and experimentation.
Scope and Limitations
This study will focus only on the mortality rate of the termites. There are several
types of extermination methods but the researchers will only focus on the use of spray.
The raw materials needed will be collected from the surrounding environment. The
information regarding the development of this study will be primarily collected from the
internet, specifically from agriculture, entomology- related and pest control websites.
Review of Related Literature
Termites
A termite is a soft, white insects living in groups which causes a serious structural
damages to the infrastructures that they eat (Merriam Webster, 2018). They are also
known as the “silent destroyers” because of their ability to damage infrastructures
without being detected immediately (National Pest Management Association, 2018),
(Orbin, 2018).
Termites are often confused to ants (Pestwiki,2018). There are several types of
termites which often depend on where they live and the types of food (wood) that they
eat. Regardless to their species, they all are a big concern to home owners especially
when they have a huge size of colonies.
