Study Notes
Life Cycle of Mosquitoes
- Mosquitoes undergo complete metamorphosis, requiring a blood meal before egg laying
- Female mosquitoes begin laying eggs within a week after mating
- Domestic mosquitoes can breed in:
- Zeers (water tanks)
- Barrels
- Latrines
- Deep wells
- Sakias
Culex Mosquitoes
- Transmitters of diseases:
- Filaria of man (Wuchereria bancrofti)
- Rift valley fever
- Encephalitis virus
- Yellow fever
- Dengue fever
- Prefer to bite during the day
Aedes Mosquitoes
- Transmitters of diseases:
- Filaria of man (Wuchereria bancrofti)
Mosquito Feeding Habits
- Anthropophilic mosquitoes (feeding only on human blood):
- Not controlled by animal barriers
- Attracted to humans rather than animals
- Zoophilic mosquitoes (feeding on animal blood):
- Can be controlled by animal barriers
- Vomit drop process:
- Flies suck fluids until their diverticulum becomes filled
- When they drop on sweet food, they vomit fluids to dissolve it and suck it again
