The Effectiveness of Chili (Capsicum frutescens) and
Kamias (Hedychium cornarium) as Natural Insect Repellant
I. Statement of the Problem
This study is conducted to determine the effectiveness of chili and kamias mixture as a deterrent for insects such as flies, mosquitoes and cockroaches. The experiment is done by spraying various concentrations of chili and kamias extract on plants and insects to determine the affectivity as well as the toxicity of these mixtures. Specifically, it aims to answer the following questions:
1. What is the most effective concentration of Chili and Kamias mixtures with the highest effectiveness as an insect repellant. 2. What is the significance of the study in terms of cost of production and effectiveness compared to commercially available insect repellants? 3. Will there be adverse effects of the natural insect repellent on the different species of insects to be used in this study?
II. Background of the Study
An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface.1 Most pesticides ans insecticides are used in homes, gardens and farms to kill or deter pests and insects. Insects and pests need to be kept away because they cause diseases and cause damage to property. Some pests like the cockroach are also very unhygienic. The most common household pesticides are chemically manufactured and may contain toxins that may be harmful to our health, especially to children. These chemically manufactured spray-can of insecticide generate fumes, releasing chemicals that spread everywhere and are inhaled. Also, most farmers use pesticides to protect their crops and increase yield. However, these pesticides seep into the soil, contaminate ground water and hence, adversely affect the food chain.
Natural pesticides are products made of only naturally occuring substances and are a much safer way to...
