Pinus insularis cones and Salix babylonica as Active ingredients in a Mosquito Repellant
Abstract. Mosquitoes have pestered land and vertebrates for millions of years. Commercial insecticides available today, however, are not environment-friendly and may be expensive. This Study aimed to develop an environment-friendly, safe, effective, and cheap mosquito repellant. Pinus insularis (pine cones) and Salix babylonica (weeping willow) leaves were gathered from different places. A solution was extracted, collected and distilled to separate the extract from the solvent. A mixture with rations of 1:1.5 and 1:25 weeping willow leaves and pine cone extracts prepared. The mixture was then tested on wrigglers and adult mosquitoes. The chi-square test was used to determine if there was an association between the death of the wrigglers and mosquitoes and the presence of the repellant. The statistical test showed that the prepared mosquito repellant was not effective.
INTRODUCTION Many harmful microorganisms are carried by mosquitoes. This way they harm human and animals. A hundreds of chemicals have been developed to act as mosquito repellants. The problem, however, is that these chemicals are expensive and pose harm to the environment. This study aims to develop an environment friendly, safe, and effective yet cheap mosquito repellant by using weeping pillow leaves and pine cones.
The activity is not success but it shows the different scientific processes to be followed in doing an experiment.
REVIEW OF RELATED LITERATURE
Mosquitoes are one of the most harmful creatures in the world, not only to humans but also to other land vertebrates as well. They carry viruses that are sometimes fatal when transmitted to humans. Diseases transmitted by mosquitoes are common in are tropics (Merit Encyclopedia, 1969).
Mosquito-borne diseases are transmitted to the body of the host through mosquito bites and contaminated
