THE PROBLEM AND ITS BACKGROUND
Introduction

Nowadays. we are sing diseases which is caused by insects like mosquito. To call some are Dengue. Hemorrhagic Fever. and Malaria wherein if non treated early it can do decease. Mosquitos are all around the corner of our environment. They are non that large but can cut off life. To command the mosquitoes. different mosquito repellant are made and the research lab chemicals are effectual but they are rather expensive and non environmental friendly. Chemicals besides are harmful to our wellness ; it may do a sudden decease in instance of improper handling. In the rural barangays there are common herbal workss used by rural folks in kill offing harmful insects like mosquitoes. And so the research was conceptualized to observe the insecticidal consequence of Alliums cepa ( Onion ) and Allium sativum ( Garlic ) on mosquitoes and do a mosquito repellant out of onion and Allium sativum. a non expensive repellant that everyone particularly the hapless 1s can afford.

Garlic and Onion contains allicin that is capable of driving mosquitoes and allicin is unfriendly to mosquitoes. Another ground is garlic and onion has besides a strong smell that overwhelms the mosquito’s sense of odor and prevents from happening their quarry ( us ) .

Statement of the Problem

This survey will be conducted to analyze if there is an insecticidal consequence in the infusion of Allium sativum ( Garlic ) and Allium cepa ( Onion ) on mosquitoes and to do a repellant out of it that will be guided with the undermentioned inquiries: * Is there an insecticidal consequence in the infusion of Allium sativum ( Garlic ) and Allium cepa ( Onion ) on mosquitoes? * Is the infusion of Allium cepa ( Onion ) and Allium sativum ( Garlic ) effectual as a mosquito repellant?

Aims

By and large. the survey aims to find if there is an insecticidal consequence of Allium cepa ( Onion ) and Allium sativum ( Garlic ) on mosquitoes.
Specifically. the survey aims to cognize if the infusion of Allium cepa ( Onion ) and Allium sativum ( Garlic ) is effectual on driving mosquitoes.

Significance of the Study

The survey can assist in driving mosquitoes for it will analyze the insecticidal consequence of Allium cepa ( Onion ) and Allium sativum ( Garlic ) on mosquitoes. This survey will be helpful to people particularly those populating with many mosquitoes around them for it will be easy for them to do it and it’s safe. And the repellant will be an environmental friendly. It can besides assist decrease the dandy fever and malaria eruption.

Scope and Restrictions

The survey will be conducted from November 2012 to December 2012. It will be conducted on a cool warm prohibitionist room. The effectivity of this repellant will be applicable to the topographic point where the experiment will be conducted.

Hypothesis

There will be no insecticidal consequence of Allium cepa ( Onion ) and Allium sativum ( Garlic ) on mosquitoes. The infusion of Allium cepa ( Onion ) and Allium sativum will non be effectual as a mosquito repellant.

REVIEW OF RELATED LITERATURE

Recently. our state is enduring from different sorts of outbreak merely like dandy fever and malaria eruption and this is caused by mosquitoes. Mosquitos are around us. they are little but they can do decease if you are bitten with it. To command these insects some of us buy expensive insect powder though it is effectual it is besides harmful. Harmful to our wellness because it contain chemicals that if mishandled can do to decease. It’s non besides environmental friendly.

Herbal repellant are normally used by rural barangays where the people find it hard for them to purchase commercially available insect powders for mosquitoes. and so the research worker was conceptualize to analyze if there is an insecticidal consequence of Allium cepa ( Onion ) and Allium sativum ( Garlic ) on mosquitoes and to do a repellant that is effectual to repell mosquitoes. a non-toxic repellant. an environmental friendly and a cheaper mosquito repellant.

Onion and Garlic has an allicin that is capable of driving mosquitoes and other insects. The allicin which is released by Allium cepa ( Onion ) and Allium sativum ( Garlic ) are unfriendly by mosquitoes. The another ground why Garlic and Onion can repell mosquitoes is their strong odor that overwhelms the mosquito’s and forestall them from happening their quarry ( us ) .

Onion

Onion is the common name for herbaceous. cold season works Allium cepa. which is characterized by an comestible. rounded bulb composed of concentric. heavy. tightly packed. and an hypertrophied foliage basses. Onion is besides the name of this comestible bulb. which is commercially valuable and known for its acrid oil that departs a strong gustatory sensation.

Onion are found in a big figure of formulas and readyings crossing about the entirety of the world’s civilizations. The whole works is comestible and is used as nutrient in some signifier or other. They are now available in fresh. frozen. canned. caramelized. pickled. powdered. chopped and dehydrated formed. Onion can be used. normally chopped our chopped. in about every type of nutrient. including cooked nutrients and fresh salads and as spicy garnish. In European civilizations they are seldom eaten on their ain. but normally act as concomitant to the chief class. Depending on the assortment. an onion can be crisp. spicy. tangy. acrid mild or Sweet.

Onion contains allicin that is capable of driving mosquitoes. Onions can besides drive mosquitoes because of its strong smell and its spicy spirit which mosquitoes hatred. Normally a ruddy onion is used by driving mosquitoes.

Garlic

Allium sativum is works grown for its bitterish bulb. which is used to season nutrients. Some workss related to garlic including the onion besides have strong spirit. The garlic bulb consists of parts called cloves. The cloves may be eaten or used for seting. A brickle papery covering called a tunic grows around each cloves ] and around the whole bulb. There are several of import constituents of Allium sativum that have been identified. and many more that have non. Alliin is an odorless sulphur-containing chemical derived from the amino acerb cysteine.

When Allium sativum bulbs are crushed. alliin is converted into another compound called allicin. Allicin appears to be one of the primary active compounds that gives garlic its characteristic olfactory property and many of its mending benefits. However. allicin is non absorbed efficaciously by the human organic structure. To battle this job. aged Allium sativum is fermented to interrupt allicin down to useable compounds. These compounds are water-soluble sulphur compounds ( S-ally cysteine and others ) and an sum of oil-soluble sulfur compounds.

Alicia is a powerful compound of Allium sativum. If the Allium sativum releases an illicit it is unfriendly to mosquitoes. They have hence evolved to avoid Allium sativum. another ground why Allium sativum can drive mosquitoes is that the strong odor of garlic overwhelms the mosquito’s sense of odor and prevents them from happening their quarry ( us ) .

RESEARCH METHODOLOGY
Materials

Genus alliums ness ( Onion ) and Alliums bowl ( Garlic ) will be the chief constituents of the repellant and will be the beginning of illicit. Cayenne Piper nigrum will be added to onion and Allium sativum to do it spicier. Liquid dish soap will be needed to do the repellant fragrant. In acquiring the infusion of Onion and Garlic. liquidizer will be used. A sprayer is besides needed wherein the repellant will be placed.

Trial Organism

Fifty mosquitoes will be collected and must be distributed every bit to five containers for the five set-ups. Mosquitoes will function as the trial being.

Test Procedure

In doing the repellant. chop into little pieces the onion and Allium sativum without skining. Put the shredded onions and Allium sativum at the liquidizer with the chili pepper Piper nigrum. Then place a 250 mol sum of H2O. Blend on a slow velocity to a milklike consistence. After intermixing topographic point the infusion of onion and garlic pin a empty bottle sprayer. Wait an hr to add 50mL liquid dish soap for the infusion will be odorous. Then agitate good.

In finding the insecticidal consequence. there will be five set up. The first repellant will hold 100g of onion and garlic. Second set up will hold 100g of onion and 70 g of garlic. Third apparatus will hold 70g of onion and 100g of Allium sativum. The 4th set-up will hold 100g of onion and 100g of Allium sativum and liquid dish soap will non be added. And the 5th set-up will be a commercial insect powder to find is what is more effectual.

One set-up will be sprayed at the one container with mosquitoes and the research worker will enter how long will all the mosquitoes decease and how many mosquito will decease in one 30 sec. 1 min. 1 min and 30 sec. and 2 min. The other set-ups will besides undergo this process.
