Another causal agency is garlic and onion has also a sacrosanct odour that overwhelms the mosquitos sense experience of tactual sensation and prevents from finding their forgo (us).Statement of the ProblemThis study pass on be conducted to examine if there is an insecticidal effect in the pull out of Allium sativum (Garlic) and Allium cepa (Onion) on mosquitoes and to make a repellent out of it that ordain 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?ObjectivesGenerally, the study aims to reconcile 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 offensive mosquitoes.Significance of the StudyThe study can help in repelling mosquitoes for it get out examine the insecticidal effect of Allium cepa (Onion) and Allium sativum (Garlic) on mosquitoes. This study testament be subservient to people especially those living with many mosquitoes around them for it entrust be easy for them to make it and its safe. And the repellent give be an environmental friendly. It can also help lessen the dengue and malaria outbreak. backdrop and LimitationsThe study will be conducted from November 2012 to December 2012. It will be conducted on a cool doting dry room. The effectiveness of this repellent will be applicable to the tail end where the experiment will be conducted.HypothesisThere will be no insecticidal effect of Allium cepa (Oni on) and Allium sativum (Garlic) on mosquitoes.
