- <p><span lang="EN-PH">Mosquito-borne diseases are major problems faced by tropical countries, leading to global morbidity and mortality. The immediate response of the public is to use chemical insecticides and repellents. However, continuous usage of these products may be harmful to public health as it may cause respiratory diseases. Natural insecticides have shown potential effects on mortifying and repelling mosquitoes. The calamansi (<em>Citrus microcarpa</em>) plant, which is abundant in the Philippines, contains components responsible for such activity as D-limonene and citronellal. These components are proven to control mosquitoes.</span></p> <p><span lang="EN-PH">The aim of this research paper was to assess the effectiveness of calamansi leaf extract as a mosquito insecticide. Additionally, this study determined the most effective concentration of the calamansi leaf extract based on having the shortest time interval between the death of the mosquito. The results of the study revealed that among the three concentrations of the ethanolic calamansi leaf extract (10 g per 100 ml, 20 g per 100 ml, and 30 g per 100 ml), concentration 3, containing 30 g of fined calamansi leaves and 100 ml of 70% ethanol, was the most effective as it obtained the shortest time interval among the two. The results of this paper proved that calamansi leaf extract is an effective mosquito insecticide. Moreover, the researchers encourage that the insecticides be evaluated in larger populations of mosquitoes to validate their effects in mosquitoes so that a broader understanding of their effectiveness in different mosquitoes may be gained.</span></p>
