SECTION 1: MOSQUITO BIOLOGY & LIFE CYCLE (Questions 1-30)
Q1. What is the primary habitat for mosquito larvae during their development?
 A. Dry soil
 B. Standing water
 C. Tree bark
 D. Leaf litter
 Correct Answer: B. Standing water Mosquito larvae are aquatic and require
standing water for development, as they cannot survive in dry environments or on
solid surfaces .
Q2. What are the four stages of the mosquito life cycle in correct order?
 A. Egg, pupa, larva, adult
 B. Egg, larva, pupa, adult
 C. Larva, egg, pupa, adult
 D. Pupa, egg, larva, adult
 Correct Answer: B. Egg, larva, pupa, adult The mosquito life cycle consists of four
stages: egg, larva (wriggler), pupa (tumbler), and adult, with the first three stages
requiring aquatic habitats .
Q3. What stage of the mosquito life cycle is the pupa?
 A. Egg
 B. Larva
 C. Adult

,  D. Transitional non-feeding stage
 Correct Answer: D. Transitional non-feeding stage The pupa is a non-feeding,
transitional stage between larva and adult that allows metamorphosis to occur
without extensive movement .
Q4. What is the typical duration of the mosquito life cycle in Alberta during summer
months?
 A. 1–2 days
 B. 7–14 days
 C. 30–45 days
 D. 60–90 days
 Correct Answer: B. 7–14 days Under optimal summer conditions in Alberta,
mosquitoes can complete their life cycle from egg to adult in approximately one to
two weeks .
Q5. Which mosquito species is known for day-time biting behavior in Alberta?
 A. Culex tarsalis
 B. Aedes aegypti
 C. Aedes vexans
 D. Anopheles quadrimaculatus
 Correct Answer: C. Aedes vexans Aedes vexans is a common day-biting species
in Alberta, particularly aggressive in open fields and known as the "floodwater
mosquito" .
Q6. What is the larval stage of a mosquito commonly called?
 A. Tumbler
 B. Wriggler
 C. Nymph
 D. Caterpillar

,  Correct Answer: B. Wriggler The larva lives in water, feeds, and develops into the
pupal stage; it is commonly called a "wriggler" due to its characteristic swimming
motion .
Q7. What is the pupal stage of a mosquito commonly called?
 A. Wriggler
 B. Tumbler
 C. Nymph
 D. Chrysalis
 Correct Answer: B. Tumbler The pupa is called a "tumbler" because of its tumbling
motion when disturbed in the water, though it does not feed during this stage .
Q8. Which environmental factor most affects mosquito population growth?
 A. Temperature
 B. Soil type
 C. Wind direction
 D. Altitude
 Correct Answer: A. Temperature Temperature directly influences mosquito
development rates, with warmer temperatures accelerating the life cycle and cooler
temperatures slowing or halting development .
Q9. How do mosquitoes survive Alberta's cold winter conditions?
 A. They migrate south
 B. They overwinter as eggs, fertilized adult females, or larvae
 C. They hibernate in leaf litter only
 D. They die off completely and return each spring
 Correct Answer: B. They overwinter as eggs, fertilized adult females, or
larvae Mosquitoes may overwinter in various stages: Aedes species as eggs, Culex
species as fertilized adult females, and some as larvae depending on the species .
Q10. Which mosquito life stage is capable of flying and biting humans?
 A. Egg

,  B. Larva
 C. Pupa
 D. Adult
 Correct Answer: D. Adult Only the adult stage has wings and the ability to feed on
blood, which is necessary for egg production in females .
Q11. What triggers mass emergence of mosquitoes in spring in Alberta?
 A. Soil compaction
 B. High wind events
 C. Rainfall and snowmelt
 D. Predator migration
 Correct Answer: C. Rainfall and snowmelt Water from precipitation or melting
snow provides ideal conditions for dormant eggs to hatch, resulting in synchronized
population surges .
Q12. Which mosquito species lays eggs singly on moist soil rather than directly on
water?
 A. Culex species
 B. Anopheles species
 C. Aedes species
 D. Culiseta species
 Correct Answer: C. Aedes species Certain Aedes species lay drought-resistant
eggs on moist soil, which can survive dry periods and hatch when water returns,
making them floodwater mosquitoes .
Q13. How does stagnant water contribute to mosquito proliferation?
 A. It provides shade
 B. It offers a breeding site for eggs
 C. It repels predators
 D. It reduces competition
