B. 4
C. 5
D. 6
Four stages: egg, larva, pupa, adult.
2. Which stage is the primary target for most control programs?
A. Egg
B. Adult
C. Larva
D. Pupa
Larvae are concentrated in water and easier to control.
3. Which mosquito genus commonly lays eggs singly on water surfaces?
A. Aedes
B. Culex
C. Anopheles
D. Psorophora
Culex eggs are laid in rafts floating on water.
4. Which genus lays eggs on dry surfaces that later flood?
A. Aedes
B. Culex
C. Anopheles
D. Uranotaenia
Aedes eggs resist drying and hatch after flooding.
5. Which mosquito rests at a 45-degree angle to the surface?
A. Aedes
B. Culex
C. Anopheles
D. Mansonia
Anopheles adults rest with the abdomen angled upward.
, 6. Which stage does not feed?
A. Larva
B. Adult male
C. Adult female
D. Pupa
Pupae are non-feeding transitional stages.
7. What do adult male mosquitoes feed on?

B. Plant nectar
C. Animal tissue
D. Water only
Only females take blood meals.
8. Why do female mosquitoes take blood meals?
A. Energy for flight
B. Hydration
C. Egg development
D. Temperature regulation
Protein in blood is needed for egg production.
9. Larvae breathe through:
A. Gills
B. Skin
C. Siphon or air tubes

B. Property values
C. Disease risk and control timing
D. Soil composition
Surveillance guides control decisions.
14.Which host amplifies West Nile virus?

C. Birds
D. Cattle
Birds are the primary reservoir hosts.
15.Humans are considered what type of host for West Nile?
A. Primary host
B. Reservoir host
