INSECTICIDAL EFFECT OF ALLIUM CEPA (ONION) AND ALLIUM SATIVUM (GARLIC) ON MOSQUITOES
An investigatory project in partial fulfilment of
the Requirement in Research II
THE PROBLEM AND ITS BACKGROUND
Nowadays, we are experiencing diseases which is caused by insects like mosquito. To name some are Dengue, Hemorrhagic Fever, and Malaria wherein if not treated early it can cause death.
Mosquitoes are all around the corner of our environment. They are not that big but can cut off life. To control the mosquitoes, different mosquito repellent are made and the laboratory chemicals are effective but they are quite expensive and not environmental friendly. Chemicals also are harmful to our health; it may cause a sudden death in case of improper handling. In the rural barangays there are common herbal plants used by rural folks in exterminating harmful insects like mosquitoes.
And so the research was conceptualized to detect the insecticidal effect of Alliums cepa (Onion) and Allium sativum (Garlic) on mosquitoes and make a mosquito repellent out of onion and garlic, a not expensive repellent that everyone especially the poor ones can afford.
Garlic and Onion contains allicin that is capable of repelling mosquitoes and allicin is inimical to mosquitoes. Another reason is garlic and onion has also a strong odour that overwhelms the mosquito’s sense of smell and prevents from finding their prey (us).
Statement of the Problem
This study will be conducted to examine if there is an insecticidal effect in the extract of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes and to make a repellent out of it that will be guided with the following questions: * Is there an insecticidal effect in the extract 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? Objectives
Generally, the study aims to determine if there is an insecticidal 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 Study
The study can help in repelling mosquitoes for it will examine the insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. This study will be helpful to people especially those living with many mosquitoes around them for it will be easy for them to make it and it’s safe. And the repellent will be an environmental friendly. It can also help lessen the dengue and malaria outbreak. Scope and Limitations
The study will 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. Hypothesis
There 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 LITERATURE
Recently, our country 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 buy 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. It’s 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 researcher 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...
