DENGUE  INFO

Egg Stage

After the female has obtained her blood meal she will find a quiet place to rest and develop her eggs. It may take several days for this to happen. Once she is ready to lay her eggs she will seek out an appropriate place. The site selected and the way the eggs are laid largely depends on the genus. If she is in the genus Aedes she will most likely lay her eggs singly on the edge of a drying puddle or near the surface of water in a container. If she is in the genus Culex or Culiseta she will lay her eggs in a raft on the surface of the water. Each raft will contain several hundred eggs. She will repeat this cycle of obtaining blood meals and laying eggs until she dies.

The duration of the egg stage is largely dependent on the species and on environmental conditions. The egg stage could last from one day to 9 months. Some mosquitoes overwinter as an egg. These eggs usually must experience a cold season and a specific day length to trigger hatching. For most species the eggs will hatch in one to seven days. When the larvae are ready to hatch they use a small temporary "tooth" on their head to break open the egg along a suture.

Larval Stage

Because the larva's skeleton is located on the outside (exoskeleton), similar to that of a crab, they must shed their exoskeleton in order to grow. All mosquito larvae shed their exoskeleton, or molt, four times; the stages between molts are called instars. Newly hatched larvae are called first instar larvaeand they are always very small and hard to see.

Mosquito larvae typically float at the surface of the water. Here they can obtain food and breathe through their siphon. The siphon is located at the base of their abdomen and is similar to a snorkel. The larvae feed on bacteria and other organic matter in the water. Brushes that are located in front of their mouths collect the food.
