The Feasibility of Tubang Bakod (Jatropha curcas) Seeds as Mosquito Repellant/Killer


Mosquito’s abound in tropical countries like the Philippines. They have been pestering land vertebrates for millions of years. Insecticides are either too harmful to both man and the environment or too expensive for the consumers. The purpose of this study is to create an environment-friendly, safe, effective and cheap mosquito repellant. Weeping willow leaves, tubang bakod seeds, tubang bakod seed hulls, onion peelings and almaciga sap were collected. The solid ones were pulverized and mixed together in three pans in 1:1:1:2:4 ratio. Two of the pans were given different amounts of the oil extracted from tubang bakod seed while the remaining one was given none. The mixtures were allowed to dry and were tested on mosquitoes for effectivity and on humans for acceptability. The results showed that tubang bakod has a significant repelling effect on mosquitoes.


Mosquitoes are one of the most unwanted, dreaded harmful insect pests known to man. They not only cause sleepless nights to humans because of their buzzes and bites but also cause serious, diseases. The mosquitoes may transmit pathogens that cause H-fever, filariasis and other less common but widespread infections among vertebrates. Commercially available mosquito repellants are big threats to human health. Others, such as the electric-powered ones, are too expensive for most Filipinos. Environment friendly, safe, effective but affordable mosquito using the tubang bakod seeds.


Mosquitoes transmit serious diseases that may sometimes lead to death. These diseases are more common in the tropics than anywhere else. But as long as the mosquitoes exist somewhere in the world, nobody is entirely safe from them.

The saliva of the mosquitoes may get infected with pathogens once they bite a carrier. These pathogens may be transmitted to the host through mosquito...
