Mosquito
Mosquitoes are members of a group of almost 3,600 small flies within the family Culicidae. “mosquito” is Spanish and Portuguese for “little fly”. Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts.
Eggs are laid
The eggs are laid on the water’s surface and hatch into aquatic larvae, or wrigglers, which swim with a jerking, wriggling movement. In most species, larvae feed on algae and organic debris, although some are predatory and may even feed on other mosquitoes. Unlike most insects, mosquitoes in the pupal stage, called tumblers, are active and free-swimming. The pupae breathe using tubes on the thorax. The adults mate soon after emerging from their pupal cases. The duration of the life cycle varies greatly depending on the species.
Attraction
Mosquitoes attract host animals by moisture, lactic acid, carbon dioxide, body heat, and movement. The mosquito’s hum results from the high frequency of its wingbeats, and the female’s wingbeat frequency may serve as a means of sex recognition.
Anopheles mosquitoes
There are three important mosquito genera. Anopheles, the only known carrier of malaria, also transmits filariasis and encephalitis. Anopheles mosquitoes recognise in their resting position that the beak, head, and body are held straight to each other but at an angle to the surface. The spotted colouring on the wings results from coloured scales. Egg-laying usually occurs in water containing heavy vegetation. The female deposits her eggs singly on the water surface. Anopheles larvae lie parallel to the water surface and breathe through posterior spiracular plates on the abdomen instead of through a tube, as do most other mosquito larvae. The life cycle is from 18 days to several weeks.
Culex mosquitoes
The genus Culex is a carrier of viral encephalitis and filariasis in tropical and subtropical climates. It holds its body parallel to the resting surface, and its beak is bent downward relative to the surface. The wings, with scales on the veins and the margin, are uniform in colour. The tip of the female’s abdomen is blunt and has retracted cerci (sensory appendages). Egg-laying may occur on almost any body of fresh water, including standing polluted water. The eggs, which float on the water, are joined in masses of 100 or more. The long and slender Culex larvae have breathing tubes that contain hair tufts. They hang heads downward at 45° from the water surface. The life cycle is usually 10 to 14 days, maybe longer in cold weather. The northern house mosquito (C. pipiens) is the most abundant species in northern regions, while the southern house mosquito (C. quinquefasciatus) is abundant in southern regions, namely the tropics and subtropics.
Aedes mosquitoes
The genus Aedes carries the pathogens that cause yellow fever, dengue, Zika fever, and encephalitis. Like Culex, it holds its body parallel to the surface with the proboscis bent down. The wings are uniformly coloured. Aedes may distinguish from Culex’s silver thorax with white markings and posterior spiracular bristles. The tip of the female’s abdomen is pointed and has protruding cerci. Aedes usually lays eggs in floodwater, rain pools, or salt marshes. The eggs are capable of withstanding long periods of dryness. The short, stout larvae have a breathing tube containing a pair of tufts, and the larvae hang head down at a 45° angle from the water surface. The life cycle may be as short as 10 days or, in cool weather, as long as several months. A. aegypti, the important virus carrier responsible for yellow fever, has white bands on its legs and spots on its abdomen and thorax. This domestic species breeds in almost any container, from flower pots to discarded car-tire casings. The eastern salt marsh mosquito (A. sollicitans), the black salt marsh mosquito (A. taeniorhynchus), and the summer salt marsh mosquito (A. dorsalis) are important mosquitoes in coastal marsh areas that experience daily or occasional flooding with brackish or salt water. They are prolific breeders, strong fliers, and irritants to animals, including humans.
Can mosquitoes kill you?
It might seem impossible that something so minuscule can kill many people, but it’s true. The World Health Organization states that mosquito bites result in more than 1 million deaths yearly. The majority of these deaths are due to malaria.
What are mosquitoes attracted to?
Mosquitoes are attracted to the carbon dioxide humans and other animals emit. They also use their receptors and vision to pick up on cues like body heat, sweat, and skin odour to find a potential host.
What are mosquitoes afraid of?
Mosquitoes are distressed by a few natural scents: cinnamon, peppermint, cedar, citronella, lemongrass, patchouli, catnip, lavender, and more. Find a favorite, and use it when you want to spend time outside.
What colour does a mosquito hate?
Unfortunately, avoiding mosquitoes isn’t as easy as choosing the right colour of clothes. When a researcher inserted their hand into the chamber wearing a green glove, mosquitos missed it, even when sprayed with CO2. Mosquitoes also ignored green, purple, blue, and white.
Can mosquitoes see in the dark?
The visual cues draw the mosquito closer to the human host. The same experiment showed that after the host’s CO2 emissions attract a mosquito, the mosquito will begin to see the host once it’s within a range of around 5 to 15 meters (16 to 49 ft.). That is true even when it’s dark outside.
Where do mosquitoes initially come from?
Scientists believe mosquitoes originated in South Africa and eventually spread to the rest of the world. Mosquitoes have evolved to the point where there are approximately 2,700 species of mosquitoes. Ancient mosquitoes were up to three times larger than today’s mosquitoes.

What smell do mosquitoes hate?
Mosquitoes have a powerful sense of smell, which they use to find accessible food sources. You can repel mosquitoes with scents they hate, like lavender, peppermint oil, geranium oil, cinnamon bark oil, lemon eucalyptus oil, citronella oil, catnip, rosemary, and pine oil.
How do I fight mosquitoes in my house?
Use insect sprays and repellents containing picaridin or DEET inside and outside the house to kill mosquitoes. Remove stagnant water around the house so mosquitoes can not breed. Change pet drinking bowls, bird baths, and vase waters at least once weekly.
How do I catch a mosquito in my room?
Grab a torch and turn off all of the lights in your room except for a tiny light source, like your phone or a small lamp. Eventually, the mosquito will make its way to the light, hopefully landing on the wall or surface near it.
Why are there suddenly mosquitoes in my house?
There’s a high chance of mosquito activity if your property is near standing water with a constant water source. Mosquitoes could quickly enter your home and lay their eggs; female mosquitoes will lay eggs in water for survival. House plants are also known to attract mosquitoes inside the house.
Can I get an STD from a mosquito?
Let’s start by clarifying that mosquitoes cannot give you human-based STDs. No research supports the claim that mosquitoes can spread HIV, Herpes, or other common STDs tested by STDcheck.com.
How many times can one mosquito bite?
An endless number of mosquito bites one of the insects can inflict. A female mosquito will continue to bite and feed on blood until she is full. After consuming enough blood, the mosquito will rest for a couple of days (usually between two to three days) before laying her eggs.
What can I put in my room to keep mosquitoes away?
Some mosquito-repulse plants include basil, lemon balm, lemongrass, lemon verbena, lemon eucalyptus, lemon thyme, peppermint, lavender, catnip, bee balm, clove, pennyroyal, citronella grass, marigolds, rosemary, garlic, and Venus flytraps (an insectivorous plant).
How long do mosquitoes live in Asia?
One female mosquito can lay up to 500 eggs in its lifetime. The average life expectancy of an adult mosquito is about three weeks.
The life cycle of mosquitoes in South Asia?
The Aedes mosquitoes have four life stages: egg, larva, pupa and adult. The entire life cycle, from an egg to an adult, takes approximately 8-10 days. Mosquitoes can live and breed inside and outside the home.
What country do mosquitoes live in?
Australia, Indonesia, the Philippines, and Brazil have the highest endemic species. However, it is the whole of Africa, South America and Asia where most mosquito-carry diseases occur.
Where do mosquitoes live?
Habitats. Some mosquitoes like to live near people, while others pick forests, marshes, or tall grasses. All mosquitoes like water because mosquito larvae and pupae live in the water with little or no flow.
When do mosquitoes go away?
Mosquito season starts slowly in the spring, top in the summer, and tapers off into fall. Mosquitoes prefer warm weather, so “mosquito season” only applies in places where winters get cold. Mosquitoes don’t go away for good until the first freeze, followed by temperatures consistently below 50 degrees.
When do mosquitoes bite?
Dusk is the period between the transition from daytime to nighttime. It is also when mosquito activity across various species tends to be the highest. Each species has its preferences: Aedes — Feeds during the day (two hours after sunrise and several hours before sunset).
How long is the life of a mosquito?
The average life expectancy of an adult mosquito is about three weeks.
Can mosquitoes fly?
How far can mosquitoes fly? Depending upon the species, mosquitoes can fly at about 1 to 1.5 miles per hour. How far can mosquitoes fly? Mosquito species preferring to breed around the house, like the Asian Tiger Mosquito, have limited flight ranges of about 300 feet. Most species have flight ranges of 1-3 miles.
Can mosquito larvae bite?
Luckily, mosquito larvae do not bite humans or animals, and even if consumed by animals drinking the water they live in, they usually do not cause harm.
The lifespan of a mosquito in days?
Male mosquitoes will stay only 6 or 7 days on mode, feeding primarily on plant nectar, and do not take blood meals. Females with enough food can live up to 5 months or longer, with the mode female life span being about six weeks.
