Insect: Mosquitoes

Chapter I Introduction Background of the conceive Mosquitoes present ar a problem for us humanes. Mosquitoes be attracted by scramble odors and the carbon dioxide in our breath. With our climate, it is easy for us Filipinos to uprise attracted by mosquitoes simply because we are sweating a lot. Because of mosquito bites, we whoremonger easily get illnesss standardized West Nile Virus, the West Nile virus is contracted when a mosquito bites a human or animal. This virus can cause fever, headache, nausea, vomiting and rash in its early stages and can lead to paralysis. Dengue Fever, a contracted oddball of mosquito bite mainly during the day.Especially dangerous for children, dengue fever is institute in general in the tropics. It resembles viral flu and can be fatal. Malaria, as well make primarily in tropical regions, mosquitoes carrying malaria bite during the night. Symptoms of this disease include fever, chills, headache, uneasiness and muscle ache. And Yel disor dered Fever, Mostly found in S unwraph the earths and Africa, yellowish fever resembles the symptoms of another(prenominal)(a)wise diseases carried by mosquitoes. In addition to these flu- kindred symptoms, yellow fever can also cause backache and jaundice and can be fatal.The menace posted by mosquito bites carry surged so much that mosquito subdue measurements are almost crucial to keep ourselves from contracting serious illnesses like the malaria or the West Nile Virus. Mosquito control is much than significant than ever before. give mosquitoes are the main culprit basis the spreading of these diseases and avoiding mosquito bites is the only self- do demeanor to remain unhurt. Some Mosquitoes that carry the West Nile virus are often active at dawn and dusk, which makes them less likely to be noticed.Mosquito bites can affirm supersensitized reactions. Itchy red bumps, for instance, are considered allergic reactions to the dirt balls saliva. More trying reactions i nclude blisters, hives, bruises and intense inflammatory reactions. Our problem that we lead to solve is the mosquitoes, because it carries the Dengue virus, which we Filipinos are aware of. As of this year, numerous wad have died because of dengue. We want that we can help in our receive way is to repel mosquito in our skin so we testament not get hurt or get a bite from a mosquito. rehearsal of the ProblemOur main goal is to create a mosquito fetid that is eco-friendly, yet legal in repelling mosquitoes. Also, compete with the standards of the commercialized revolting. The researchers aim to answer these hobby questions 1. Are the radical mosquito repellent stick abouts break off than the commercialized repellents? 2. Is victimisation rat tummy and catmint execu remit in making strong complete mosquito repellent sticks? 3. Which is more effectual? Basing on the number of mosquitoes repelled and killed. ( catmint stick, lemon wander stick, or two combined. ) Hyp othesisThe organic mosquito repellent sticks can be a substitute to a commercialized repellent, because it is more eco-friendly and maybe less harmful to the body especially the lungs. The researchers reducek that it is possible to make organic mosquito repellent sticks using lemon snitch and catnip, since those two agents are cognise to be in force(p) grammatical constituents in making mosquito repellents. The researchers believe that the lock with both agents is much more effective, because the effects of both agents combine is much better than just one of the catnip or lemon reveal. Definition of Terms . Mosquito-repelling infuriate -Usually shaped into a stick, and typically made from a desiccated scatter of pyrethrum powder. -In the study, this refers to the reaping that the researchers are trying to create. 2. lowlife bullet -A fragrant tropical grass that yields embrocate that smells lemony. -This refers to the tall grass used in making the repellent sticks. 3. vomit upnip -A inwrought mosquito repellent. -One of the main ingredients of our mosquito repellent sticks. 4. Malaria -Caused by a leech called Plasmodium, which is transmitted via the bites of infected mosquitoes. In this study, this is the disease that is common in pitiable countries caused by a parasite 5. Dengue Fever -A contracted example of mosquito bite mainly during the day. Especially dangerous for children, is found primarily in the tropics. -In the study, this is the virus that is astray spreading in the Philippines that we want to forbid. 6. Nepetalactone Itis an organic involved first isolated from the plant catnip. -In the study, it is the main component of catnip that makes mosquitoes be repelled. Significance of the Study The significance of this study aims to help heap embarrass mosquitoes from staying in homes or schools.The researchers want to help multitude who get soaked by pesky mosquitoes. The researchers want to help certain people who invade mosquito es in their everyday life. 1. General Public a. The masses in general, since everyone of necessity to be protected from these insects for they are harmful to the body. 2. Campers b. These people like male child scouts and mountaineers like to stay outdoors, such as forests and mountainous areas, where there are a lot of mosquitoes. So the researchers want to help them repel mosquitoes on their camps. 3. Parents c.Parents want to prevent their children from getting bit by mosquitoes making them. Our organic mosquitoes repellent sticks depart be a great help to these people 4. The Poor d. These people cant afford to buy repellents for their homes. This will aid them, because it is easy to make and really affordable even to the poor. mountain range and Limitation Our scope of the study is to make effective mosquito repellent sticks, to prevent mosquitoes from invading homes and other places. To lessen the risk of diseases caused by mosquitoes, such as Dengue Fever and Malaria.As a g roup we can only regulate our organic repellent sticks to only prevent mosquitoes, but not to other insects. The researchers only aim to repel mosquitoes, but not to the extent that we would drive out their existence. Chapter II Review of related literature Mosquito Coil Mosquito rolling is mosquito-repelling scent, ordinarily shaped into a spiral, and typically made from a dried counterpane of pyrethrum powder. The coil is commonly held at the center of the spiral, suspending it in the air, or wedged by two pieces of fireproof nettings to allow continuous smoldering.Burning usually begins at the outer end of the spiral and progresses slowly toward the centre of the spiral, producing a mosquito-repellent smoke. A typical mosquito coil can measure well-nigh 15 cm in diameter and lasts up to 8 hours. Mosquito coils are widely used in Asia, Africa, and South America. Bad effects Burning mosquito coil (MC) releases various olfactory propertytic compounds like benzo pyrenes, benz o-fluoroethane and particulate matters. These chemicals have the potential to produce harmful effects on airways as demonstrated by histopathological changes in the airways of various animal models.It has been estimated that burning one MC over 8 hours produces particulate matter smoke (as measured as PM2. 5) equivalent to rough 100 cigarettes. Particulate matter pollution has been shown to increase airway hyper reactivity and cause decrements in lung function. Mosquito The mosquitoes are a family of small, midge-like flies the Culicidae. Although a fewer species are harmless or even useful to humanity, most are a nuisance because they consume furrow from living vertebrates, including humans. The females of many species of mosquitoes are blood eating pests.In feeding on blood, more or less of them transmit exceedingly harmful human and livestock diseases, such as malaria. Some regime argue accordingly that mosquitoes are the most dangerous animals on Earth. ball of some mosq uitoes float on the water in rafts. Larvae, often called wigglers, have a soft body, a hard head and a existent tube, or siphon, at the tip of the abdomen. Pupae are shaped like a comma, and are commonly called tumblers. Adults have delicate legs, a long bole and one pair of transparent wings Dengue Dengue fever, also known as break bone fever, is an infectious tropical disease caused by the dengue virus.Symptoms include fever, headache, muscle and joint pains, and a symptomatic skin rash that is similar to measles. In a small correspondence of cases the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood plate allows and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs. Dengue is transmitted by several species of mosquito indoors the genus Aedes, principally A. aegypti. The virus has four different references infection with one type usually gives lifelong resistor to t hat type, but only short-term immunity to the others.Subsequent infection with a different type increases the risk of severe complications. As there is no commercially available vaccine, prevention is sought by reducing the habitat and the number of mosquitoes and limiting exposure to bites. Treatment of discriminating dengue is supportive, using either oral or intravenous rehydration for spiritless or moderate disease, and intravenous fluids and blood transfusion for more severe cases. The incidence of dengue fever has increased dramatically since the 1960s, with around 50100 million people infected yearly.Early descriptions of the condition date from 1779, and its viral cause and the transmission were elucidated in the early 20th century. Dengue has pass away a global problem since the sulfur World War and is indigenous in more than 110 countries. Apart from eliminating the mosquitoes, work is ongoing on a vaccine, as well as medication targeted directly at the virus catmint catnip is a perennial herb and atom of the Mint familyLabiatae. It is ingrained to Europe Asia, however has become naturalised in America Canada after being introduced.There are approximately 250 species of catmint. The active ingredient which causes this is an essential oil called nepetalactone, which can be found in the leaves arc of the plant. Other constituents include Acetic Acid, Alpha and beta-nepetalactone, Citral, Nepetalactone, Geraniol, Dipentene, Citronellol, Nerol, Butyric Acid, Valeric Acid and Tannins. catmint is also known by the following names Cataria,Catmint, Catnep, Catrup, Cats Heal All,Cats-play, Cats Wort, Catswort, Catwort, Chi Hsueh Tsao, Field Balm, Garden Nep, Herba Cataria, Herba Catti, Nebada, Nep. maizegrass Lemongrass herb is a very everyday plant found commonly in India and used for medicinal, food and mosquito and insect repellent products. The lemongrass oils are also used in cosmetics, soaps, perfumes, dyes and odorizes along with thousands of other products. There are many different and related types of lemongrass, all belong to the grass family, Poaceae. East Indian and West Indian lemon grass are popular names for Cymbopogon flexuous and Cymbopogon citratus. Lemon grass is an evergreen, native to Southeast Asia, India, Myanmar, Thailand, Sri Lanka, and Australia.Another type of lemongrass also used in insect repellents comes from Malaysia. The thin stems and foliage of lemon grass ranges from blue-green to gold, and the flowers are white, cream, or green. Lemongrass grows to around 8 feet in height in some cases with the majority of species tapering off off at 4 feet. Lemon grass grows best in full sun and moist soil and cab be propagated by dividing the root clump into sections. Lemon grass leaves can be dried or frozen but require rehydration before use. Lemon grass is very mild, rating only a one on the warmth scale.It is mostly known as a common staple found in Thai, Vietnamese, Cambodian, Indonesian, and Ind ian cooking. Lemon grass is used in curry, crusade fry, soups, and marinades and it can be sauteed, mixed with soy sauce and spices, and used as a marinade. Lemongrass is particularly popular with seafood due to its distinctive lemony smelling and flavor. Effectiveness In a 2004 study presented at the California State Science Fair, a 25-percent lemon grass solution was time-tested against a commercial 15-percent Deet spray.The lemon grass brew was 51 percent effective in repelling mosquitoes, compared to an effectiveness of 81 percent for the Deet product. The study cogitate that lemon grass showed promise as a partial reclamation for Deet-based repellents. In a study conducted in 2010 at Maranatha Christian University, researchers compared lemon grass stem show to citronella oil. Citronella oil proved more effective at repelling mosquitoes than the highest concentration of the lemon grass extract. Both studies make known that while lemon grass does repel mosquitoes, it does not work as well as other products.Nepetalactone Nepetalactone is aterpenecomposed of two isoprene units, with a total of ten carbons. Its chemical structure is similar to that of the valepotriates derived from the herb valerian, which is a mild central nervous system sedative (or stimulant to some persons). The molecular formula for nepetalactone is C10H14O2. The first fully characterized methylcyclopentane monoterpenoid. Isolated from the volatile oil of catnip produced byNepeta cataria Nepetalactone , its cas register number is 21651-62-7.It also can be called Nepetalactone cis-trans-form Cyclopenta(c)pyran-1(4aH)-one, 5,6,7,7a-tetrahydro-4,7-dimethyl-, (4aS,7S,7aR)- Cyclopenta(c)pyran-1(4aH)-one, 5,6,7,7a-tetrahydro-4,7-dimethyl-, (4aS-(4aalpha,7alpha,7aalpha))- . It is an organic compound first isolated from the plant catnip. Chapter lead METHODOLOGY This chapter presents the projects research design, list of materials and their quantities needed for the research, and the sc ience laboratory procedures which are the pre-lab procedure, laboratory proper, and post laboratory. Research Design This study made use of an experimental research design.The experimental and control groups were used in this study. This design is illustrated as follows. carry over 3. 1 Set-up Location Product employ Quantity of Mosquitoes Set-up A Enclosed room Catnip Incense charge 10 mosquitoes Set-up B Enclosed room Lemongrass Incense Stick 10 mosquitoes Set-up C Enclosed room Catnip and Lemongrass Incense Stick 10 mosquitoes Set-up D Enclosed room CommercializedIncense Stick 10 mosquitoes Subject of the Study -The researchers used mosquitoes as the subject to the experiment. Ten mosquitoes in each container, with a total of forty mosquitoes (Caught with the mosquito trap).Materials Needed One (1) Masher Four (4) Mosquito traps third (3) Incense holders Ten (10) Incense sticks Two (2) Catnip Two (2) Lemon batch Four (4) Containers of Mosquitoes One (1) Commercialize d repellent Pre-Lab Procedures Catnip and Lemon cheat were collected by the researchers. The researchers pulverize the Catnip and Lemon Grass to extract the juices from them. The researchers thusly put the extracted juices into 3 containers. First with only the catnip, Second with only the lemon grass, lastly with both catnip and lemon grass in the container. research lab Proper ProceduresThe researchers applied the juices of catnip to three worsen sticks and was labelled Set-up A, lemongrass extract juice to the other three incense sticks and labeled Set-up B, and both the lemon grass extract and catnip extract juices to the be incense sticks and labeled Set-up C. The commercialized repellent was labeled Set-up D. The researchers applied the extract juices thoroughly by hand or by cotton swabs. The researchers past let the incense sticks rest for about 6 to 10 minutes, to let the extract juices be absorbed by the incense sticks. Post Laboratory ProceduresThe researchers put the incense sticks in their respective incense holders in order. The researchers and then put sample 1 in an enclosed room beside the mosquito trap. The researchers then lit up the incense sticks and released the first batch of mosquitoes. The researchers closely go on the experiment. The researchers then waited for the incense sticks to disintegrate (15 to 20 minutes). Then the researchers do the similar with the sample 2, sample 3, and to the commercialized repellent. The researchers recorded the results based on how many mosquitoes were repelled and killed.Chapter IV Presentation, Interpretation and Analysis of Data This chapter shows the presentation, interpretation and analysis of info gathered after a thorough investigation. Table 4. 1 Mosquitoes that were effectively repelled Experimental Quantity(number of sticks) Mosquitoes Repelled sentence Element (minutes) Catnip 3 4 out of 10 20 Lemongrass 3 3 out of 10 20 Both combine 3 5 out of 10 20 The table above shows that the Incense stick with the Catnip effectively repelled 4 mosquitoes and the Incense stick with the Lemongrass only killed 3 out of 10 mosquitoes.On the other hand, the Incense stick with the Catnip and the Lemongrass combined showed the best results in this test. This shows that the Catnip and Lemongrass combined will yield better results than the Catnip and Lemon grass solo but the results of this test were unsatisfactory because only half of the mosquitoes tested were repelled effectively. Table 4. 2 Mosquitoes that were effectively killed Experimental Quantity(number of sticks) Mosquitoes Repelled Time Element (minutes) Catnip 3 1 out of 9 20 Lemon Grass 3 1 out of 9 20Both Combined 3 3 out of 9 20 The table shows that Catnip and Lemongrass killed only 1 out of 9 mosquitoes but when combined the product repels 3 out of 9 mosquitoes, this proves that the organic incense stick will yield better results if both Catnip and Lemongrass combined, rather than the Catnip and Lemongrass a lone because it only kills 1 out of 9 mosquitoes as shown on the table. Table 4. 3 Mosquitoes that are killed by the commercialized product Experimental Quantity(number of coils) Mosquitoes Repelled Time Element (minutes) Baygon 1 9 out of 10 20This table shows that the Baygon coil effectively killed 9 out of 10 mosquitoes. This proves that our incense stick with Lemongrass, Catnip or both cant compete with a better, well known commercialized product like that of the Baygon. Baygon uses stronger chemicals unlike that of our incense stick, which uses organic plants. Chapter 5 Summary, Conclusion, and Recommendations Summary The researchers made a mosquito coil that is organic and eco-friendly. The researchers also studied between a commercialized mosquito coil with their own mosquito repellent.The researchers also made mosquito traps for trapping mosquitoes for the researchers experiment. Their product is effective and it produced some demonstrable results. The catnip and lemongrass combined shows the best results, based on how much mosquitoes it repelled and killed, end-to-end the experiment. Conclusions Throughout the experiment, the researchers found out that the commercialized mosquito coil is more effective than our organic mosquito repellent. The researchers found out that it is possible to make a mosquito coil using catnip and lemongrass because the two agents are an effective mosquito repellent.Out of the three mosquito coils we had made, the catnip and lemongrass combined showed the best results basing on our experiment. Recommendations The researchers recommend the people to use natural and safe mosquito coils that can be home made. The researchers also recommend using stronger plants to use in making mosquito coil. The researchers also recommend adding scented aroma to the coils/sticks so it can be a pleasing feeling for the people who will use it. The researchers also recommend using both Catnip and Lemon Grass for making a mosquito coil because i t is effective.References From Internet Brian, Dan.
