Introduction: Citrus fruits and derived products have a beneficial effect on the human health because of its nutritional and antioxidant properties and their consumption is associated with a decrease in the incidence of cardiovascular disease and reduction of the risk of certain cancers and also. During the processing of citrus fruit for juice, peels are the primary by products and phytochemicals are abundant in citrus peels. As you would expect, pesticide, herbicide and fungicide residues are highest on the peel of oranges These compounds have been associated with healthy properties ascribed

to

their

antioxidant

activity

and

abilities.

Phenolic compounds and antioxidant activities in citrus peel have been widely investigated and they have been found to possess antiallergenic, antiartherogenic, anti-inflammatory, antimicrobial, antioxidant, antithrombotic, cardioprotective and vasodilatory effects. All species help move chi stagnation. Although all species share certain properties, there are some differences; Mandarin Orange Peel is an anti-inflammatory, cholagogue, carminative, diuretic and tonic, and the green or unripe orange peel is a cholagogue and carminative. The bitter Orange Peel moves chi stagnation and is a carminative, stimulant, stomachic, expectorant and tonic. Additionally, different species/parts have different uses. Mandarin Orange Peel – catarrh, chest congestion, gas, indigestion; Green or Unripe Citrus Peel — abscess, bloating, breast cancer, gall bladder congestion, liver stagnation; Bitter Orange Peel – flatulence, indigestion, stagnation in the digestive tract, tumors. Using the peels as a digestive aid stimulates the production of hydrochloric acid. The high content of bioflavonoid helps to strengthen the capillaries and tissues in the body. Orange flower water is used as a sedative. Meanwhile, mosquitoes are a family of small midge-like flies, the Culicidae. Although a few species are harmless or even useful, most cause a nuisance by sucking blood from vertebrates including humans. Accordingly, some authorities argue that disease-bearing mosquitoes are the most dangerous animals on earth. With increasing reports of the harmful effects DEET has on

humans, there has been a move to repellents which are organic. These are of the kinds that have had traditional household purposes before their being used as mosquito repellents.

Title: Anti Mosquito Repellant Candle Additive from Mandarin Orange (Citrus reticulata blanco)

II. Objective of the Experiment: 1. This experiment will be conducted to know more the accurate and faster way of killing

mosquitoes that causes dengue. 2. To make an experiment that could really help the middle-class families as well as

everybody in avoiding to be sucked by the mosquito carrier of dengue.

III. Statement of the Problem: This study aims to determine whether extract from the peels of

mandarin orange (citrus Reticulata Blanco) can be a good additive for an anti-mosquito repellant candle.

IV. Background of the Study:

Mandarin Orange (Citrus reticulata blanco) is said to have an essential oil from its peels that is used as flavoring, perfumes and in medicinal use. An essential oil obtained from the leaves and young twigs are called 'petit grain oil'. Yields are around 0.5%. In traditional Chinese medicine, the dried peel of the fruit is used in the regulation of ch'i, and also used to treat abdominal distension, and to enhance digestion. All that mandarin eating adds up to a lot of peels. As you would expect, pesticide, herbicide and fungicide residues are highest on the peel of oranges. The fruit, including its peel is used to treat allergic reactions. Another important part of the peel that is widely used is the oil present in it. It acts as an effective insect repellent and is also used in the production of furniture polishes. The peel initially tastes somewhat sweet and spicy but has a bitter and pungent after-taste.

An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. Insect repellents help prevent and control the outbreak of insect-borne diseases such as malaria, Lyme, dengue fever, bubonic plague, and West Nile fever. Pest animals commonly serving as vectors for disease include the insect’s flea, fly, and mosquito; and the arachnid tick. So, in this case, we used candle as an insect repellant to kill mosquitoes that causes dengue. V. Hypothesis: We can say that extract from the peels of mandarin oranges will help us to have a more accurate and faster means of killing mosquitoes, due to high acidity this can help as an additive.

VI. Methodology Materials: Used Candles Candle Wick Mandarin Oranges Pan Candle Molder Container Mosquito Net

Procedure: Collecting Mosquitoes

1. First, we filled the container with water depending on the container where you will make

the experiment. 2. Second, we will wait until we find some mosquito eggs(wrigglers).

3. Then, we covered it with fishing net. 4. After which, we just waited for the wrigglers to fully developed into an adult mosquito.

Candle with Extract of Mandarin Orange Making

1. First, we need to gather all the materials for the candle making. These are the candles,

and mandarin oranges.

2. Second, we extracted the peels of our mandarin oranges (Citrus reticulata blanco)

3. Next, we’ll going to cut the candle, but make sure we’ll get the candle wick of it.

4. Then, we will melt the candle in the pan with a moderate temperature.

5. After the candle has been melted, we will mix the melted candle with the extracted

peels of our mandarin oranges (Citrus reticulata blanco).

6. Let the mixture, blend properly.

7. Then we in a candle

8.

will put our mixture mold.

Finally we allowed it to dry up.

•

VII.

For the final procedure, after we have collected mosquitoes and made our candle, we can now test and light up our candle with our mosquitoes. Ifyou can’t believe in this, use an ordinary candle and light it up for one day at a place that is full of mosquitos and the next day light up a candle with the peels of mandarin orange (Citrus reticulata blanco) and see the difference.

Observation: We have observed that our anti mosquito repellant candle additive from mandarin

orange is a good anti mosquito repellant because it kills mosquitoes rapidly. As we light up our candle, mosquitoes, die faster. the scent of the mandarin oranges helps the candle to be more effective as an anti mosquito repellant candle.

VIII.

Conclusion:

Therefore, we conclude that extract from the peels of mandarin orange (Citrus reticulata blanco) can be a good additive for an anti mosquito repellant. It could be one of the best product of country for avoiding dengue if possible to be sold on markets, it could be cheaper and effective. With this great idea, middle-class family could avoid mosquito without paying higher on buying repellants ,it will be a great difference to everyone as well.
