ACKNOWLEDGEMENT
We would like to extend our sincere gratitude to Miss Nemea Mae Flores Cosido for giving us the chance to show our best in this Investigatory Project and for guiding us while we were conducting our experimentation. We would also like to acknowledge Miss Jerlyn Abne Toledo for the free use of computer and Mister Antonio Martel Cordero for watching us while we were doing our project when Miss Cosido was not around. Thanks also to Merriam Online Dictionary, Amerikana Encyclopaedias and Wikipedia, the free Encyclopaedia for the definition of hard words, and to Sto. Tomas College’s dry and wet laboratories for the materials, equipment and venue of experimentation. All of these will not be done without the persevering help and continuous guidance of our Lord, our greatest praise to him.

B. Statement of the Problem

This study tries to find out the potency of the combined extracts of the Chili Pepper and Kamias as a mosquito repellent, thus the prevention of Dengue Fever.

1.) Can the extracts of Chili Pepper and Kamias prevent from having mosquito bite especially that of the Aedes aegypti, a Dengue - causing mosquito? 2.) What are the natural repellent substances contained in these two plants? 3.) Are these effective and safe to use? Will this mosquito killer (Chili Pepper and Kamias) can affect the health or even kill the person who accidentally took it? 4.) Is the said mosquito killer (Chili Pepper and Kamias) cheaper than the commercial ones? C. Hypothesis

Alternative Hypothesis
1.) The combined extracts of the Chili Pepper and Kamias can be used in the making of mosquito repellent, thus the prevention of Dengue Fever.

Null Hypothesis
2.) The combined extracts of the Chili Pepper and Kamias cannot be used in the making of mosquito repellent.

D. Significance of the Study

This study is very useful and important for people, environment and community. Since this research determines if Chili Pepper and Kamias extracts can be used as a mosquito repellent, the people will now have alternatives to use if they are not financially - capable of buying expensive insecticides. It is also very relevant in the changing world because our product is nature - fuelled, it will have no impact or lesser impact in the community.

When we say nature - fuelled, it means the materials or ingredients used come from nature. Meaning nature’s substances enable us to produce such product. We were also able to say that it is very relevant to the changing world because Earth is now experiencing climate change and severe warming due to human practices, the product has no impact or lesser impact to the community because it doesn’t contain any chlorofluorocarbon that would contribute to the atmosphere’s pollution like what the commercial products being advertised and sold are doing. We say lesser impact if people made a choice to mix the substance with perfume to cover the awful smell. And perfume by the way has minimal component of chlorofluorocarbon.

E. Scope and Delimitation of the Study

The period of research is about one month, a period where detainment is much observed but it was okay in the end though. We, the researchers brought a one - day old Chili Pepper picked from Bonifacio Street, Danao City and Kamias from Lang - Lang, Danao City in Sto. Tomas College dry laboratory. Mortar and pestle, test - tube, test - tube rack and holder, hot plate, stirring rod, and beaker were also used.

This study does not cover the idea of what would be the effect of the product in the case of skin diseases. The study focuses only on the effect of the product to the mosquitoes and if...
