TYPES OF MOSQUITOES AND IMPORTANCE

  1. Aedesspp
  2. Anopheles spp
  3. Culexspp

3.1 Aedes Mosquitoes
Bite in day time. They breed in fresh, stagnant or brackish water


  • Aedesaegypti is charcoal to black with silvery white markings. Its identifying marks include a single median silver-white stripe on top of the thorax, tarsal (Lower Leg) segments ringed with white, and the abdominal segments narrowly and singly banded on top with white.

  • Breeds almost entirely on old tires, tin cans, flower vases and other similar manmade containers.

  • Eggs are laid singly above the water line or in depressions subject to flooding

  • The adult rests and feeds with its body parallel to the surface
               

3.2 Anopheles Species
Remains inactive during the daytime and rest cool, damp, dark, protested sites. Mosquitoes bite primarily during the period from dusk to dawn.

  • They may bite during the daylight hours in an area that is heavily shaded or in a room that is dark.
  • Its dark brown with solid-coloured legs. There are 4 dark spots near the centre of each wing.
  • Its breeds in permanent freshwater sites that contain aquatic vegetarian such as swamps, ponds and small lakes. Most species will breed in accumulated clean water, but some species breed only in trees holes.
  • Eggs are laid singly on the water surface.
  • Absence of siphon (air tube) in larvae and those rests parallel to water surface. When feeding on a host, the body and proboscis lie in one plane/axis at an angle of 45 to the surface.

3.3 Culex Species
Includes the house mosquitoes that develop in urban areas, and the western encephalitis mosquito more commonly found in rural areas.




  • It’s brown with white of gray markings its identifying marks include charcoal to black legs, except for a cream-colored area on the upper leg. The abdominal segments each have a broad white cross band on top that is widest along the midline and broadly jointed to lateral patches.
  • Oviposit on the water, but glue their eggs into a rati larvae have siphons through which they obtain air from the surface, enabling it to feed below the surface lying angular.
