(Cymbopogon citrates) LEAVES AS AN ALTERNATIVE

Background of the Study
Dengue victims are abundantly spreading in our society and they are caused by the known Aedes aegypti. These mosquitoes are merely found in places where there are abandoned tires and containers filled with stagnant water, Mosquitoes are also known as the most dangerous killers in the world where they can victimize an approximate of 2 to 3 million people in a year.

Mostly found on leading stores are expensive commercial chemical mosquito repellants. These mosquito repellants may contain toxic chemicals that can cause respiratory diseases to us, human beings. In connection with this, we must also consider that not all of us can afford to purchase these said mosquito repellants. These commercialized mosquito repellants contain toxins like DEET ( N,N-Diethyl-meta-toluamide ) that are widely used by most residents in our community.

Objectives of the Study
This study is designed to produce an alternative mosquito repellant out of carabo manure with extract of lemongrass and eucalyptus leaves combined together.

Specifically, it seeks to answer the following questions
a. What are the chemical components of carabao manure combined with lemon grass and eucalyptus extract that would repel the mosquitoes? b. Is the carabao manure with lemongrass and eucalyptus extract effective compared to the chemical commercial mosquito repellant? c. What are the effects of chemical components from carabao manure combined with lemongrass to the environment and to human beings? d. Is the natural alternative mosquito repellant safe to human beings and to the environment?

Assumptions and Hypotheses:
1. The carabao manure combined with lemongrass and eucalyptus extract as an alternative mosquito repellant is efficient. 2. The materials used to make an alternative natural mosquito repellant are adequate. 3. The natural mosquito repellants is as effective as the commercial chemical repellants.

1. There is a significant difference between the commercial chemical mosquito repellent and the natural mosquito repellent. 2. There is relative effectiveness of the natural mosquito repellant and the commercial chemical mosquito repellant.

Definition of Terms:

DEET- N,N-Diethyl-meta-toluamide; slightly yellow oil; most common active ingredient in insect repellants.

Eucalyptus- a diverse genus of flowing trees in the myrtle family, Mytaceae; members of the genus dominate the tree flora of Australia.

Dengue Fever- it is also known as break bone fever, an acute febrile infectious disease caused by the dengue virus; dengue is usually transmitted by the mosquito Aedes aegypti.

Carabao Manure- a good organic fertilizer; contains 18.5% nitrogen, 43.7% phosphoric acid and 9.6 potash; a good source of fuel either as dried dung, or in generating biogas or methane.

Lemongrass- traditionally used by Indians as a medicine; has numerous uses and properties in aromatherapy.

Scope and Delimitation
This study was conducted to determine the effectiveness of carabao manure with lemongrass and eucalyptus extract as an alternative mosquito repellant. The aspects looked into were the components of carabao manure with extract of lemongrass and eucalyptus that would repel the mosquitoes and the nature of mosquitoes.
