Beyond the nuisance factor, mosquitoes are carriers, or vectors, for some of humanity’s most deadly illnesses, and they are considered as public enemy number one of the community. Mosquito-borne diseases cause millions of deaths worldwide every year with a disproportionate effect on children and the elderly in developing countries. There are more than 3,000 species of mosquitoes, but the members of three bear primary responsibility for the spread of human diseases. Anopheles mosquitoes are the only species known to carry malaria. Culex mosquitoes carry encephalitis, filariasis, and the West Nile virus. And Aedes mosquitoes, of which the voracious Asian tiger is a member, carry yellow fever, dengue, and encephalitis.

The latest outbreak in the province, located around 400 kilometers (249 miles) south manila, has caused particular alarm because it began before the rainy season start in June, when mosquitoes are less plentiful.

Dengue is spread by mosquitoes that breed in stagnant water and usually bite people during daytime. Dengue fever is recurring problem in the Philippines but while the number of incidents this year is slightly lower in nationwide, it has been spiking in certain areas.

Nowadays commercial mosquito repellent sprays are being use for mosquitoes.it provides adequate protection against a host of mosquito-borne diseases, such as yellow fever, malaria, encephalitis, filariasis and dengue fever. But commercial mosquito repellent are chemical derived concentrations, so it has a side effects, including mouth ulcers, nausea and blisters/burning.

Gabi corms is a native to southern India and southeast Asia. It is a perennial, tropical plants primarily grown as root vegetable for its edible starchy corm, and as a leaf vegetable. It is a food staple in African, Oceanic and south Indian cultures and is believe to have been one of the earliest cultivated plants. Gabi is thought to have originated in Indo-Malayan region, perhaps in eastern India and Bangladesh, and spread eastward into Southeast Asia, eastern Asia, and the Pacific islands; westward to Egypt and the eastern Mediterranean; and then southward and westward from into East Africa and West Africa, whence it spread to the Caribbean and Americas. It is known by many local names and often referred to as “elephant ears” when grown as ornamental plant.

Eggplant is a species of nightshade commonly known in british English as aubergine and also known as melogene, garden egg, or guinea squash. It is known in Southeast Asia and south Africa as brinjal. It bears a fruit of the same name(commonly either “eggplant” in American, Australian English and sometimes Canadian English, or “aubergine” in British English and Canadian English) that is widely used in cooking, most notably as an important ingredient in dishes such as mousakka and ratatouille. As a member of the genus Solanum, it is related to both tomato and the potato. It was originally domesticated from the wild nightshade, the thorn or bitter apple, S. incanum, probably with two independent domestications, one in the region of South Asia, and one in East Asia.

This scenario motivates the researchers to help solve the problem by coming up with a Eggplant Extract and Gabi Corms as Mosquito Repellent that would replace the commercial mosquito repellent.
The study aimed, to compare the effectiveness of Eggplant (Solanum melongena) Extract and Gabi Corms (Colocasia esculenta) as Mosquito(Aedis aegypti) Repellant. Specifically,...
