Mosquitoes are small insects That always makes us feel annoyed when I see or hear it fly around, because we know that if a mosquito bites. There will be cars We might as malaria, dengue fever and encephalitis. Or yellow fever has over 3,000 species of mosquitoes, the mosquitoes do not carry any disease, most humans are about 100 species that can kill. Biologists found Mosquito bites are the only female mosquitoes. It needs blood to lay eggs at the time it would take a bite beak pointed like needles penetrate into the blood vessels under the skin. Then let saliva to prevent blood clotting time it was sucker. If the mosquito-borne disease. Pathogens present in saliva, it enters the body. The chemicals contained in the saliva will make people feel itchy mosquito bites. Some people have allergies Or feeling faint and suffocation. So biologists interested to know. How mosquitoes feed Why some people are bitten more often. But some mosquitoes do not mess with it. Why Anopheles mosquito (Anopheles gambiae), so bite around the feet and ankles, but the mosquito Anopheles atroparous to bite the face. And we will prevent mosquito bites, however, so biologists also found that in the eyes of mosquitoes each person has a chance of being bitten are not equal. This is because our body temperatures vary. The time to exhale carbon dioxide emissions in an amount equal. And has a different odor. For protection against mosquito bites In general, could use chemical N, N-diethyl-3-methyl-benzamide or cream, calamine lotion and caladril the skin to keep the mosquitoes away. And simultaneously, we should dress entirely to protect the skin from being bitten mosquitoes (Aedes aegypti) mosquitoes are vicious and horrible it was named after the Anopheles mosquito, because the body has black and white stripes. Mosquito-in Diptera, there are several life cycle. In each cycle Its shape and the way the food is not the same, the mosquitoes begin life in an egg. Over time, about 24 hours, the eggs will hatch into larvae that float to the surface. And respiratory organs are at the tail end use tap water as larvae, 95 percent of the time during this period, including food, water mites, bacteria and small plants. Are rich in dirty water. Eating consistently and constantly. Larvae grow faster and have legs, wings, and mouth appear, then enter the pupa state. If nothing bothers It will float up to the surface. But the time has come against the shadows It will immediately dive During this time it will not eat or excrete it. Until the condition is completely mosquitoes. Even in the initial phase will be the nectar of flowers placed near it was not interested, but again 20-24 hours later, the boy or girl is getting hungry mosquitoes. The male will fly for nectar flowers. And will not bite But like crawling on the skin The female mosquitoes if given the choice between water sweetened with blood. It will choose the blood of adult mosquitoes with a keen eye. The antennae to smell them. So if the female mosquito's antennae were cut. Even just a little hungry It does not bite As usual, it likes to bite people indoors than outdoors. It lurks in the dark fabric. And female mosquitoes do not bite people at night. And if your hands warm with cool mosquito island. It will warm your hands But if there is only one choice for dinner. It was very cold hands Islands appreciated. Mosquito willingly hand over drying wet hands. If a mosquito flying prey in a closed container with a volume of 27,000 cubic centimeters. It will take between 5-30 seconds to fly to the victim in the arm when flying island skin. It walked a few steps before the beak hit 75 degree angle to the skin. All six legs lean on the skin. It takes approximately 50 seconds to 2:30 minutes to penetrate through the skin using its mouth to suck blood, and only five seconds to pull out the beak. Therefore, in the blood once. Aedes is about 3 milligrams of blood and blood as germs. With built-in mosquito will creep into the body of a man who was mosquito bites immediately. And even the mosquito salivary ducts are cut. It can also suck blood. But if all six legs are cut. Although it is still flying But you can not bite people. It needs at least three legs to stabilize the bite. The nerve is called the ventral nerve cord of the mosquito. It also controls the amount of blood. If this nerve is cut, mosquito stomach to drink blood until death. Or, if not dead, it is comatose and dying in the next 24 hours later, the mosquito-borne dengue fever (Dengue Haemorrhage Fever-DHF) to people that doctors call this disease that dengue because it is the bacteria that cause it. Patients with high fever and bleeding dengue word comes from the French West Indies and Danga in Swahili in East Africa. Because of that region in the 18th and 19th century are diseases that people called hard threats such Danga In 2336 American physician Benjamin Rush has reported an outbreak of dengue fever in the city of Philadelphia. The capital of the United States recognizes that the current doctor. Dengue fever is caused by the dengue virus and the patient may show symptoms three types, the first patients will have a flu or flu-like symptoms are runny nose, sore throat, joint pain, and skin rash. But ultimately, these symptoms will disappear when the patient is a child under the age of 15 receive medication for Type 2 usually occurs in young adults. Patients with high fever is a body temperature of about 39-41 ° C for 4-5 days, a red, red face, feeling anxious, headaches, body aches, sore throat, vomiting, bone pain, feeling weak, feeling depressed appetite. little urine, nausea, abdominal pain or bleeding gums. Then it will reduce a fever for two days. Then the fever would rise another 80 percent of patients have a rash or blood spots (petechiae) under the skin and spots start to appear on the back of the hand or foot before. Then it spreads to the arms, legs, torso and neck, a rash may appear normal for 2 hours or days at a third of the patients have bleeding in the intestines and stomach. Vomiting blood or coffee color. And defecate into black
