How Much Does They Hind The Household?

The Culicidae family has three families, Toxorhynchitinae, Anopheliae and Culicinae, of which the two families Anophelinae and Culicinae have important disease vectors. Identify and distinguish mosquitoes based on the shape of the adult larvae. At present, some cases of similar physical appearance are identified by molecular biology.
Subfamily Toxorhynchitinae
There is only one genus Toxorhynchities with 66 species. Mosquitoes are large in size, both males and females are not blood-sucking, long proboscis are curved downwards

. Larvae are carnivores of other mosquito larvae living in the same nest and are therefore used in biological struggle to kill other mosquito larvae.
Family Anphelinae
There are three varieties in this subfamily: Bironelle Theoblad, Chagasia Cruz, Anopheles Meigen, of which Anopeles is important in transmission.
The adult Anopheles-like belly has no scales, the dice jaw is equivalent to the proboscis in both males, particularly in the male the last burn the bulging dice bulge like a racket Most of Anopheles' wings have numerous black streaks on the flanks and veins
Eggs are laid separately, floating on the water. Eggs shaped like a boat or a shuttle, carrying two buoys on either side.



. Thanks to these two floats, the eggs float to the surface.
The larvae have two breathing holes located close to the flank face of the eight abdominal abdomen. Therefore, when the larvae come to the water to breathe, the body must be horizontal to the water surface. The larvae are usually quiet water and have many aquatic plants floating on the surface such as algae, algae, floating leaves, etc. The water market for Anopheles larvae is as diverse as fresh water, salt water, brackish water, etc depending on the species of Anopheles
Anopheles female mosquitoes often attack at night, there are blood-sucking species indoors, there are species that suck blood outside the house. The ecology of Anopheles mosquitoes is suitable for areas with many trees and forests. Urbanization places are not suitable for Anopheles development. Anopheles mosquito is the only vector that transmits malaria parasites to humans.



. Some species can transmit lymphatic filariasis to humans.
Family Culicinae
Mosquitoes belonging to this family have scales on their bellies. The female dice jaw is much shorter than the tap, while the male has the same long jaw as the tap but the tail does not expand. The Culicinae subfamily has 29 varieties but only three of which are important vectors for human transmission: Aedes, Culex and Mansonia
Aedes has about 36 sub-varieties and more than 800 species in the world. Some adult mosquitoes are usually black or dark brown, with many white scales on the hips and the back of the chest. The legs often have white spaces at the nodes. Eggs are laid separately on the surface of the water, which is rhombus, black or dark brown. The larva has a chop-shaped tubule in the eight abdominal abdomen. Therefore, when the larvae reach the water surface to breathe, the breathing tube is adjacent to the water surface and the head is lowered, so the larvae body looks like they are suspended below the water surface.



. Most Aedes mosquitoes lay eggs in clean water such as rainwater, nesting boxes are outdoor rainwater containers or indoor water containers. Only a few species of Aedes play a vector role in the transmission of arbovius or lymphatic filariasis to humans
Culex has nearly 800 species in the world. Cylindrical eggs are laid in a circle, floating on the surface of the water thanks to a small float at one end. A nest can be a lagoon with many organic substances and sewers. Some Culex species are vectors that transmit arbobirus and lymphatic filariasis.
Like Mansonia there are 25 species. Mosquitoes lay spiky spines sticking into the underside of leaves of aquatic plants such as Pistia stratiotes, duck-eared rat or Salvinia cuculata, Eichhrnia crassipes. Larvae and pupae have hard, chitinized breathing tubes that attach themselves to the roots of the above aquatic plants for oxygen, Mansonia is a vector that transmits worms to humans only.
