The alarming case of dengue in the country is spreading widely and their innocent victims are continued to rise. Many companies, NGO’S, even the DOH (Department of Health) were alarmed by the rapid increase of the dengue carrying mosquitoes. Department of Science and Technology (DOST) continues to develop possible solution in this critical situation. Filipinos are terrified with this. DOST and DOH continue to search any alternatives to solve this problem. Eucalyptus and lemon grass are one of the specimens which show the characteristic of compounds in repelling mosquitoes with the help of carabao manure. It can serve as an effective medium which the extract of eucalyptus and lemon grass can mix with carabao manure to produce an effective mosquito coil. This is one of the ways that can help to decrease the rate of death rate due to the cases of dengue. This mosquito coil made out of carabao manure, eucalyptus and lemon grass extract can be an alternative medium to reduce the case of dengue related problems, because of the contain chemical component of the subject of the study. Consequently, with this product also known as “katol” can be a good buster against mosquitoes due to the efficiency of it.

Dengue victims are continuously spreading in our society and they are caused by the prime suspect also known as the “Aedes aegypti”. These breed of mosquito are merely found in places where stagnant water occurs such that abandoned tires, containers and street canals. Mosquitoes are the most dangerous killers in the world where they victimized an approximate of 2 to 3 million people in a year. Mostly found on leading stores are the commercialized chemical based mosquito coils. These coils contains high level of toxic chemicals that cause respiratory illness, likely occur to children having 5 yrs. old and below of age. Like DEET (N, N-Diethyl-meta-toluamide) that are widely used by most residents in our community. Mosquito coils help to prevent and to control the outbreak of diseases such as Malaria, Dengue fever and West Nile fever. In connection with this, DOST (Department of Science and Technology) studied that carabao manure is an effective alternative medium for commercialized mosquito coils. And some studies showed that extracts of lemon grass and eucalyptus leaves do possess some ability to repel mosquitoes because of its lemony, herbaceous, citronella like odor and P-Methane-3, 8-diol chemical component. P-Methane-3, 8-diol component are also know as an active ingredients used in mosquito repellents. It smells is similar to menthol and acts as coolant, so it is said to be similar to a low concentrated mosquito repellent with DEET. So the researcher do have the idea to combine the extract of lemon grass and eucalyptus leaves and mix it to the carabao manure that serves as the base of effective alternative mosquito coil.

The study is designed to produce an effective mosquito coil out of carabao manure with an extract of lemon grass and eucalyptus leaves combined together. Specific Objective:
Specifically, it seeks to answer the following questions:
a) Is the LEMOCALYNURE KATOL shows effectiveness compared to commercialized chemically base mosquito coil? b) Does LEMOCALYNURE KATOL can sustain its flammability under a certain time? c) Is LEMOCALYNURE KATOL hazardous to one’s health?
H Y P O T H E S E S
1) The carabao manure with the extract of lemon grass and eucalyptus leaves can be an efficient alternative for commercialized mosquito coil. 2) LEMOCALYNURE KATOL can sustain its flammability under a short period of time. 3) There are no signs of harmful effects that can be seen on the natural component of the variables of the product.
