Partial fulfilment of the Requirement Essay

THE PROBLEM AND ITS BACKGROUNDIntroductionNowadays, we are experiencing diseases which is caused by insects akin mosquito. To name just about are Dengue, Hemorrhagic Fever, and Malaria wherein if not treated proto(prenominal) it piece of ass cause death. Mosquitoes are on the whole rough the corner of our environment. They are not that big but after part cut off life. To lock the mosquitoes, different mosquito arch are made and the laboratory chemicals are legal but they are quite expensive and not environmental friendly. Chemicals to a fault are harmful to our health it may cause a explosive death in case of improper handling. In the rude barangays in that respect are putting green herbal plants used by rural common people in exterminating harmful insects like mosquitoes. And so the research was conceptualized to detect the insecticidal feeling of genus genus genus genus genus Alliums cepa (Onion) and Allium sativum ( ail) on mosquitoes and have got a mosquito repe llent unwrap of onion plant and ail, a not expensive repellent that every mavin especially the poor ones puke afford. garlic and Onion contains allicin that is capable of repelling mosquitoes and allicin is inimical to mosquitoes. An new(prenominal) designer is ail and onion has as well a strong odour that overwhelms the mosquitos sense of olf movementory sensation and prevents from finding their prey (us).Statement of the ProblemThis subscribe to lead be conducted to view if on that point is an insecticidal effect in the kindle of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes and to throw away a repellent out of it that go forth be guided with the following questions * Is there an insecticidal effect in the repeat of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes? * Is the extract of Allium cepa (Onion) and Allium sativum (Garlic) effective as a mosquito repellent?ObjectivesGenerally, the study aims to patch up if there is an insecticid al effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes.Specifically, the study aims to know if the extract of Allium cepa (Onion) and Allium sativum (Garlic) is effective on repelling mosquitoes.Significance of the resumeThe study can help in repelling mosquitoes for it allow examine the insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. This study testament be helpful to people especially those living with more mosquitoes around them for it go forth be easy for them to make it and its safe. And the repellent bequeath be an environmental friendly. It can also help lessen the dengue and malaria volcanic eruption. cathode-ray oscilloscope and LimitationsThe study result be conducted from November 2012 to December 2012. It go out be conducted on a cool warm dry room. The effectiveness of this repellent will be applicable to the place where the experiment will be conducted. dead reckoningThere will be no insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. The extract of Allium cepa (Onion) and Allium sativum will not be effective as a mosquito repellent.REVIEW OF RELATED LITERATURERecently, our realm is suffering from different kinds of outbreak just like dengue and malaria outbreak and this is caused by mosquitoes. Mosquitoes are around us, they are small but they can cause death if you are bitten with it. To control these insects some of us demoralise expensive insecticide though it is effective it is also harmful. Harmful to our health because it contain chemicals that if mishandled can cause to death. Its not also environmental friendly.Herbal repellent are commonly used by rural barangays where the people find it difficult for them to buy commercially available insecticides for mosquitoes, and so the research worker was conceptualize to examine if there is an insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes and to make a repe llent that is effective to repell mosquitoes, a non-toxic repellent, an environmental friendly and a cheaper mosquito repellent.Onion and Garlic has an allicin that is capable of repelling mosquitoes and other insects. The allicin which is released by Allium cepa (Onion) and Allium sativum (Garlic) are inimical by mosquitoes. The some other reason why Garlic and Onion can repell mosquitoes is their strong smell that overwhelms the mosquitos and prevent them from finding their prey (us).OnionOnion is the common name for herbaceous, cold season plant Allium cepa, which is characterized by an edible, round light bulb composed of concentric, fleshy, tightly packed, and an enlarged leaf basses. Onion is also the name of this edible bulb, which is commercially valuable and known for its pungent inunct that departs a strong taste.Onion are found in a large number of recipes and preparations spanning almost the totality of the worlds cultures. The in all plant is edible and is used as f ood in some form or other. They are now available in fresh, frozen, canned, caramelized, pickled, powdered, eggbeater up and dehydrated formed. Onion can be used, usually chopped our sliced, in almost every type of food, including cooked foods and fresh salads and as spicy garnish. In European cultures they are rarely eaten on their own, but usually act as accompaniment to the main course. Depending on the variety, an onion can be sharp, spicy, tangy, pungent mild or sweet.Onion contains allicin that is capable of repelling mosquitoes. Onions can also repel mosquitoes because of its strong odour and its spicy flavour which mosquitoes hate. commonly a red onion is used by repelling mosquitoes.Garlicgarlic is plant grown for its sharp-tasting bulb, which is used to season foods. Some plants link to garlic including the onion also hold back strong flavour. The garlic bulb consists of parts called cloves. The cloves may be eaten or used for planting. A brickle papery covering call ed a tunic grows around each cloves and around the whole bulb. There are several important components of garlic that have been identified, and many more that have not. Alliin is an odourless sulfur-containing chemical derived from the amino acidulent cysteine.When garlic 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 odor and many of its heal benefits. However, allicin is not absorbed effectively by the human body. To combat this problem, hoary garlic is fermented to break allicin down to usable compounds. These compounds are water-soluble sulphur compounds (S-ally cysteine and others) and an step of oil-soluble sulphur compounds.Alicia is a powerful compound of garlic. If the garlic releases an extracurricular it is inimical to mosquitoes. They have therefore evolved to avoid garlic, another reason why garlic can repel mosquitoes is that the strong smel l of garlic overwhelms the mosquitos sense of smell and prevents them from finding their prey (us).RESEARCH METHODOLOGYMaterialsAlliums mantle (Onion) and Alliums stadium (Garlic) will be the main components of the repellent and will be the character of illicit. Cayenne pepper will be tallyed to onion and garlic to make it spicier. Liquid truelove soap will be undeniable to make the repellent fragrant. In getting the extract of Onion and Garlic, blender will be used. A sprayer is also needed wherein the repellent will be placed.Test OrganismFifty mosquitoes will be placid and must be distributed equally to fiver containers for the five set-ups. Mosquitoes will practise as the test organism.Test ProcedureIn fashioning the repellent, chop into small pieces the onion and garlic without peeling. Place the chopped onions and garlic at the blender with the cayenne pepper. past place a 250 mol amount of water. Blend on a slow speed to a whitish consistency. After blending place the extract of onion and garlic pin a empty bottle sprayer. Wait an hour to add 50mL liquid dish soap for the extract will be odorous. Then shake well.In determining the insecticidal effect, there will be five set up. The frontmost repellent will have 100g of onion and garlic. wink set up will have 100g of onion and 70 g of garlic. Third setup will have 70g of onion and 100g of garlic. The fourth set-up will have 100g of onion and 100g of garlic and liquid dish soap will not be added. And the fifth set-up will be a commercial insecticide to determine is what is more effective.One set-up will be sprayed at the one container with mosquitoes and the researcher will record how long will all the mosquitoes die and how many mosquito will die in one 30 sec, 1 min, 1 min and 30 sec, and 2 min. The other set-ups will also bear this procedure.RESEARCH PLANStudents flesh Kamille Joy P.
