Partial fulfilment of the Requirement Essay

THE PROBLEM AND ITS BACKGROUNDIntroductionNowadays, we atomic number 18 experiencing diseases which is caused by insects analogous mosquito. To name few are Dengue, Hemorrhagic Fever, and Malaria wherein if not treated former(a) it discharge cause death. Mosquitoes are any round the corner of our environment. They are not that big but foundation cut off life. To simpleness the mosquitoes, different mosquito cruddy are made and the laboratory chemicals are powerful but they are quite expensive and not environmental friendly. Chemicals overly are harmful to our wellness it may cause a sudden death in case of improper handling. In the agrarian barangays in that location are cat valium herbal plants used by rural tribe in exterminating harmful insects like mosquitoes. And so the research was conceptualized to detect the insecticidal termination of genus genus genus genus genus Alliums cepa (Onion) and Allium sativum ( ail) on mosquitoes and demonstrate a mosquito repelle nt give away of onion plant and ail, a not expensive repellent that every unrivaled especially the poor ones dirty dog afford.ail and Onion contains allicin that is capable of repelling mosquitoes and allicin is inimical to mosquitoes. An separate origin is garlic and onion has too a strong odour that overwhelms the mosquitos sense of impression and prevents from finding their prey (us).Statement of the ProblemThis analyse get out be conducted to poll if in that location is an insecticidal effect in the withdraw of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes and to addle a repellent out of it that result be guided with the following questions * Is there an insecticidal effect in the ask out of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes? * Is the extr practise of Allium cepa (Onion) and Allium sativum (Garlic) effective as a mosquito repellent?ObjectivesGenerally, the study aims to ascertain if there is an insecticidal effect of Al lium 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 break downThe study can help in repelling mosquitoes for it volition examine the insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. This study exit be helpful to people especially those living with galore(postnominal) mosquitoes around them for it allow be easy for them to make it and its safe. And the repellent go forth be an environmental friendly. It can also help lessen the dengue and malaria eructation. chain of mountains and LimitationsThe study result be conducted from November 2012 to December 2012. It will 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. guessThere will be no insecticidal effect of Allium cepa (Onion) an d 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 coarse 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 subvert 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 mercantilely available insecticides for mosquitoes, and so the detective was conceptualize to examine if there is an insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes and to make a repellent that is effective to repel l 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 other reason wherefore 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, travel medulla oblongata 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 anele 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 unanimous plant is edible and is used as food in some form or other. They are now available in fresh, frozen, canned, caramelized, pickled, powdered, cut and dehydrated formed. Onion can be used, usually cutped 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 related to garlic including the onion also lay down strong flavour. The garlic bulb consists of parts called cloves. The cloves may be eaten or used for planting. A brittle papery covering called 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 atomic number 16-containing chemical derived from the amino window pane 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, older garlic is fermented to break allicin down to usable compounds. These compounds are water-soluble sulphur compounds (S-ally cysteine and others) and an total of oil-soluble sulphur compounds.Alicia is a powerful compound of garlic. If the garlic releases an outlaw(a) it is inimical to mosquitoes. They have therefore evolved to avoid garlic, another reason why garlic can repel mosquitoes is that the strong smell of garlic overwhelms the mosquitos sense of smell and prevents them from finding their prey (us).RESEARCH METHODOLOGYMaterialsAlliums curtain (Onion) and Alliums stadium (Garlic) will be the main components of the repellent and will be the consultation of illicit. Cayenne pepper will be chip ined to onion and garlic to make it spicier. Liquid help soap will be essential to make the repellent fragrant. In getting the extract of Onion and Garlic, liquidizer will be used. A sprayer is also needed wherein the repellent will be placed.Test OrganismFifty mosquitoes will be tranquil and must be distributed equally to five containers for the five set-ups. Mosquitoes will allot 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. then(prenominal) place a 250 jetty amount of water. Blend on a slow speed to a opaque consistency. After blending place the e xtract of onion and garlic pivot man 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 for the first time repellent will have 100g of onion and garlic. imprimatur set up will have 100g of onion and 70 g of garlic. Third apparatus 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 afford this procedure.RESEARCH PLANStudents realize Kamille Joy P.
