THE PROBLEM AND ITS BACKGROUND
Introduction
Dengue is a disease that causes the death of many Filipino. Many
researchers and doctors’ experiments and studies show different ways to solve
the increasing number of dengue cases. They have come up with the solution of
using a mosquito coil, but it is proven that some mosquito coil products have a
hazardous chemical which can possibly harm someone’s health. The
researchers have thought a concept of making a mosquito coil that is organic and
contains fewer chemicals.
Organic mosquito coil is a type of a coil that doesn’t use artificial
chemicals which lessen the bad effect of those substances in the human body
system. One of the most frequently use organic material is lanzones peel
because of its chemical substance called tannin and just like the lanzones peel,
kakawate also possess this kind of chemical. Tannin is proven as an effective
chemical in making an insecticide which Kakawate leaves also have this
biochemical. Farmers who used Kakawate (as rat killers) observed that when
rats eat it, their hands stiffen, and they get bloated and die of hemorrhagic
poison. The active substance in Kakawate is not a rapidly acting substance and
needs repeated doses for it to be effective and unlike commercially prepared
mosquito coil; it is less lethal in case of accidents.
In an effort to help the government combat the disease and eradicate
mosquito carrier, the researchers determined the effect of Madre de Cacao
(Gliricidia sepium) leaf on mosquito larvae. Studies have shown that the plant
Madre de Cacao is an insect repellant and has the ability to kill many insects
which can become potential carrier of many diseases. At present there is still a
wide use of commercial and synthetic chemicals to destroy pests which are
potential carriers and are expensive. The researchers are aware of the risk of
high toxic chemical compounds and become interested in using natural
pesticides derive from plants as a means of destroying pests hence the conduct
of this study.
Objectives
1.) The objective is to produce an organic mosquito coil with the use of
Kakawate leaves (Gliricidia Sepium). Organic by means that it has fewer
chemicals that can harm someone’s health.
2.) The aim of the study is to determine if Kakawate leaves is an effective
mosquito coil.
Statement of the problem
It will specifically seek for the answer on the following questions
1. Do the Kakawate leaves as mosquito have a capacity to decrease the
number of mosquitoes in a specific area?
2. Is there any significant difference between Kakawate leaves (Gliricidia
Sepium) as mosquito coil and other commercialize mosquito coil in terms
of their effect on human’s health?
Hypothesis
Based on the formulated research problem, this study hypothesized that
Kakawate leaves (Gliricidia sepium) as mosquito coil have no significant
difference with those commercialize coils in terms of causing health risk on
human’s body.
Setting of the Study
The study will be conducted at brgy. San Guillemo, brgy. Maybancal, brgy.
San Juan, brgy. San Pedro and brgy. Lagundi that is located at Morong, Rizal
Philippines. These places were recently become mosquito habitats due to the
weather that causes some people to have dengue. Province of Rizal is part of
Region IV-A Calabarzon that also show a huge number of dengue cases.

Significance of the study
The findings of this study are significant to the following:
People. This study will give some knowledge that Kakawate leaves, which
are being ignored by many people, are essential and can be use as mosquito
killer. It will help people prevent or lessen the number of casualties related to
mosquito diseases.
Society. The study will also contribute to the benefit of society knowing
that a lot of solution are already propose in killing mosquitoes but the numbers of
Filipino’s having dengue are still increasing around the globe.
Future Researchers. This will help them as they conduct similar studies
about mosquito coil and/or repellent.
Definition of terms
The following terms are operationally defined for common understanding:
Aedes aegypti - the yellow fever mosquito is a mosquito that can spread dengue
fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other
diseases.
Dengue - is a mosquito-borne tropical disease caused by the dengue virus.
Kakawate leaves (Gliricidia Sepium) - an adaptable, fast growing, precociously
seeding tree, with the ability to disperse seeds up to 40 m from the parent tree
from exploding pods. It is a colonizer of disturbed ground and has become a
weed in Jamaica, is regarded as a potential weed in Australia, though in many
countries its ability to spread is restricted because of the low frequency at which
it sets seeds. It is a moderate or potentially invasive species.
Hazardous chemical - as defined by the Hazard Communication Standard
(HCS) is any chemical which can cause a physical or a health hazard.
Insecticides - substances used to kill insects. They include avicides and
larvicides used against insect eggs and larvae, respectively.
Mosquito coil - a spiral typically made from a dried paste of pyrethrum powder,
which when lit burns slowly to produce a mosquito-repellent smoke.
Organic - produced or involving production without the use of chemical
fertilizers, pesticides, or other artificial agents.
Tannin- a yellowish or brownish bitter-tasting organic substance present in some
galls, barks, and other plant tissues, consisting of derivatives of gallic acid, used
in leather production and ink manufacture.

Review of Related Literature
The review of the study focuses on the different related literature and
studies that can help the present study to be specific this study will focus in the
mosquito coils and in Gliricidia sepium (kakawate) leaves. Facts were from the
Internet in order to get the needed information for the study.
Foreign Literature
Beever (2015) stated that, on any given day, numerous confounding
variables affect mosquito bite frequency. These include the ambient temperature,
wind speed, and humidity; the species of mosquito, the mosquitoes’ level of
hunger, and the density of the mosquito population; and the test subject’s age,
sex, activity level, and biochemical attractiveness to the mosquito. In this study,
measures were taken to minimize or eliminate these variables. For instance, the
potential effect of variations in test subject age, sex, activity level, and
biochemical attractiveness to the mosquitoes were eliminated by using a single
test subject. Further, the effect of variations in ambient temperature, wind speed,
and humidity, as well as variations in mosquito species, hunger, and density
were minimized by testing all four body sites, all three insect repellents, and the
placebo simultaneously.
Phillips (2012) implies that, the insecticidal activity of 4 mosquito coils
containing pyrethroid ester insecticides and 1 mosquito coil containing 15%
citronella oil was evaluated against adult female Anopheles albimanus, Aedes
albopictus and Culex quinquefasciatus. Two of the pyrethroid mosquito coils
containing 0.08% meperfluthrin showed the strongest insecticidal activity, and all
4 pyrethroid coils produced significantly higher mortality than the citronella coil
across all 3 test species
According to Cofie (2009), the report is said have emphasised that the
billows of smoke from the burning coil that keeps the mosquitoes at bay also find
their way into the lungs of humans. Sometimes a mosquito coil user catches a
cold, nose gets stuffed up and his throat is scratchy. According to experts,
mosquito coils are made mostly from a chemical named pyrethrum, which stings
the eyes of mosquitoes and thus keep them at bay. Pyrethrum has been in use
for centuries as an insecticide, and is well trusted. It is natural extract from the
chrysanthemum flower, produced by drying the leaves of the flower. Breathing in
too much smoke is also said to increase the risk of asthma and cause persistent
wheezing in children. Smokeless coils do not make things any easier because
the harmful substances are still in the coil. According to reports, pyrethrum enters
the lungs while breathing, and at high doses, can potentially damage the central
nervous and immune systems. Common symptoms from exposure to pyrethrum
can include headache, nausea, vomiting, skin or eye irritation and inflammation.
If ingested, it can cause numbing of the tongue and lips, convulsions, muscular
fibrillation, respiratory issues and even death.
Local Literature
Calleja (2013) implied that Field demonstrations conducted in several
parts of the Ilocos region, Sta. Catalina said proved Rabena’s discovery that the
kakawate leaves’ botanopesticide effectively eliminated rice weevils, rice bugs
and worms in ricefields. The botanopesticide solution is prepared by way of
chopping the kakawate leaves and soaked in water overnight to extract
coumarins and using a strainer, the leaves are separated from the solution. The
resulting solution is sprayed to the ricefield and the best time to do it is from eight
o’clock to nine o’clock in the morning and from five o’clock to six o’clock in the
afternoon. These times, worms and pests are coming out from the leaves making
the solution more effective. If applied earlier or later, its effectiveness would not
be maximized as pests are still hibernating. Applying the solution under extreme
sunlight will also reduce its effectiveness as the pests hide from the heat of the
sun.
It is placed in Rodenticidal Potential of Gliricidia Sepium (2009) that
Gliricidia sepium (kakawate) is a multipurpose legume tree that is used in many
tropical and subtropical countries as a live fencing, fodder, coffee shade, green
manure, and rat poison. In Philippines, the extact obtained from its leaves is used
to remove external parasites. Gliricidia sepium (kakawate) is also used for its
medicinal and insect repellent properties. It is also a fast-growing ruderal species
that takes advantage of slash and bump practices in its native. Rats are some of
the hated pest in the Philippines because they feed on their properties like
clothes, shoes and more they can also cause diseases like Leptospirosis,
Eosinophilic reason, reaserchers developed a rodenticide out of gliricidia sepium
(kakawate) tree.

METHODOLOGY OF RESEARCH
This chapter deals with the research design, it also describes the subject
and procedure of the study that deals with the step in making mosquito coil made
in kakawate leaves (Gliricidia Sepium).
Research Design
According to Key (1997), Experimental design is a blueprint of the
procedure that enables the researcher to test his hypothesis by reaching valid
conclusions about relationship between dependent and independent variables. It
also refers to the conceptual framework within which the experiment is
conducted.
This study applied variables which include experimental group (creating a
mosquito coil and testing its effect) and control subjects, specifically negative
control. Hence, it is appropriate to use experimental design to provide accurate
results and to determine if Kakawate leaves has the power to kill mosquitoes and
to see if it works better compared to commercialize coils. By using this research
design, an attempt is made to hold all other variables except the dependent
variable constant - control.
At first, Kakawate leaves are burnt in a place where there are a lot of
mosquitoes. After burning a one branch of kakawate leaves, the presence of
mosquitos’ decreases in an approximately four hours. The researchers then
proceed in experimenting and creating kakawate leaves as well as testing it in
mosquito habitats.
The proponents observe the effect of the mosquito coil within two days
and the presence of mosquitoes are not seen. To meet the study’s objective, the
researchers also compare the effect of Tiger Katol and Kakawate coil in terms of
killing mosquito and human health.
It is highly recommended that further studies must be done for the precise
results with the help of higher laboratory test and professional scientists.
