CHAPTER 1
Introduction

Background of the Study
Every year, the World Health Organization (WHO) estimates that 50-100 million people all over the world fall victim to dengue fever. And every year, 20,000 of these victims end up dead (the Philippine Star, 2012). According to the report of the Philippine Association of Entomologists (PAE), the incidence and threat of dengue continue to rise, year after year. (Samaniego, 2012). This deadly disease is just caused by a single bite of a carrying mosquito. The mosquito is a common flying insect that is found around the world. The mosquito is often a carrier of diseases, such as malaria, encephalitis, yellow fever, dengue fever, dog heartworm, West Nile virus, and many others. The females, who drink blood, can carry disease from one animal to another as they feed. The mosquito goes through four separate and distinct stages of its life cycle and they are as follows: Egg, Larva, pupa, and adult. It has been found out by studies that buyo, lime and papaya has potential properties that can terminate mosquito larvae. This study entitled ‘Buyo (Piper betle L.), Lime (Citrus aurantifolia), and Papaya (Carica papaya L.) Leaves Powder against Mosquito Larvae ’ aims to investigate the effectiveness of the three leaves powder on the idea of destroying first the source of the problem by terminating first the larvae.

Objective of the Study
This study, aims to determine the capability of the three plants’ leaves namely: Buyo, Lime and Papaya as a terminating agent, specifically it aims to: 1.Determine the efficacy of the three plant’s leaves against mosquito larvae in the form of powder. 2.Determine if there is a significant difference between the effects of the treatments towards the mosquito larvae.

Statement of the Problem
This study aims to determine the efficacy Buyo, Lime and Papaya in terminating mosquito larvae. Specifically, it seeks to answer the following questions: 1.Can the three plants serve as a newfound terminating agent for mosquito larvae? 2.Is there any significant difference between the experimental and control set-ups? 3.Is there any further effect on the final treatment on the test organisms? Statement of Hypothesis

Based on the foregoing problems, the researchers formulated the following null hypothesis: 1.The three plants cannot serve as a newfound terminating agent for mosquito larvae. 2.There are no significant difference between the experimental and control set-ups. 3.There are no further effects on the final treatment on the test organisms. Statement of the Hypothesis

The researchers infer that:
1.The three plants can serve as a newfound terminating agent for mosquito larvae. 2.There is a significant difference between the experimental and control set-ups. 3.There is a further effect on the final treatment on the test organisms.

Significance of the Study
According to the report of the Philippine Association of Entomologists (PAE), the incidence and threat of dengue continue to rise, year after year. (Samaniego, 2012). The number of deaths from the dengue virus also rose to 328, which is higher than the 293 cases recorded during the same period last year. This deadly disease is just caused by a single bite of a carrying mosquito. This study aims to prevent destroying first the source of the problem by terminating first the larvae without triggering bad side effects. The study may further serve as the baseline information about the worth of the selected plants.

Scope and Limitation of the Study
This study, ‘Buyo, Lime, and Papaya Leaves Powder against Mosquito Larvae,’ focuses on the potential properties of the three plants towards mosquito larvae in different set-ups. This study limits and focuses only to the topics related to this project.
