THE PROBLEM AND ITS BACKGROUND
Introduction
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?
