Citrofortunella microcarpa, Plant Extract, Calamansi, Aedes aegypti, mosquitocide


Citrofortunella microcarpa (Calamansi) is a well-known fruit worldwide which is abundant in Asia. The leaves of this fruit are packed with essential oils that benefit human beings, because it drives mosquitoes away. Mosquitoes are carriers, or vectors, for some of humanity‟s most deadly illnesses, and they are the number one public enemy in the fight against global infectious disease. According to the World Mosquito Organization, the mosquito, Aedes aegypti, is the primary specie responsible for transmitting viruses such as zika, dengue, chikungunya and yellow fever to people. This study aimed to identify the efficacy of the Calamansi leaf extract as a natural based mosquitocide. There were three different concentrations used: 50%, 75%, and 100%. Subsequently, 10 cages were labeled for each concentration, the positive control, and the negative control. There were 255 Aedes aegypti mosquitoes divided in 10 different cages. Citrofortunella microcarpa (Calamansi) leaf extract were administered every 15 minute interval. The Calamansi leaf extracts effectively exterminated the mosquitoes, though 100% concentration that had the fastest time of effect. Data show that there was no significant difference among the concentrations. In addition, the effect of Citrofortunella microcarpa (Calamansi) extract has no significant difference with commercial insecticide.
