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.Continue Reading here
