Alberta Biting Fly (Mosquito) Control Certificate Practice Exam
Questions with Correct Answers (Verified Answers)
Question 1: What is the primary goal of Integrated Pest Management (IPM) in mosquito control?
A. Complete eradication of all mosquito species
B. Managing mosquito populations to reduce nuisance and disease risk while minimizing environmental
impact
C. Applying adulticides on a fixed weekly schedule regardless of need
D. Eliminating all standing water regardless of its ecological value
CORRECT ANSWER: B. Managing mosquito populations to reduce nuisance and disease risk while
minimizing environmental impact
Rationale: IPM focuses on sustainable, long-term prevention and suppression using a combination of
techniques, prioritizing environmental safety and targeting specific problems rather than blanket
eradication.
Question 2: What are the four stages of a mosquito’s life cycle?
A. Egg, nymph, pupa, adult
B. Egg, larva, pupa, adult
C. Larva, pupa, cocoon, adult
D. Egg, instar, pupa, adult
CORRECT ANSWER: B. Egg, larva, pupa, adult
Rationale: Mosquitoes undergo complete metamorphosis, which consists of four distinct stages: egg,
larva, pupa, and adult. The first three stages are aquatic.
Question 3: Which life stage of the mosquito is aquatic and breathes atmospheric air through a
siphon?
A. Egg
B. Larva
C. Pupa
D. Adult
CORRECT ANSWER: B. Larva
Rationale: Mosquito larvae, often called "wigglers," are aquatic and breathe through a respiratory siphon
located at the posterior end of their abdomen, which they extend to the water's surface.
Question 4: How do mosquito pupae breathe?
,A. Through gills located on the abdomen
B. Through thoracic trumpets at the water's surface
C. Through a siphon at the posterior end
D. They do not breathe; they are dormant
CORRECT ANSWER: B. Through thoracic trumpets at the water's surface
Rationale: Mosquito pupae, or "tumblers," are also aquatic and active. They breathe through a pair of
respiratory trumpets located on their thorax, which they keep at the water's surface.
Question 5: Under optimal warm conditions, how long can it take for a mosquito to develop from egg
to adult?
A. 1 to 2 days
B. 7 to 10 days
C. 30 to 40 days
D. 2 to 3 months
CORRECT ANSWER: B. 7 to 10 days
Rationale: In warm summer temperatures with abundant food, many common mosquito species in
Alberta can complete their aquatic development from egg to adult in as little as 7 to 10 days.
Question 6: What is "diapause" in the context of mosquito biology?
A. A period of suspended development to survive unfavorable conditions
B. The rapid multiplication of eggs in warm water
C. The process of a larva molting into a pupa
D. The mating flight of adult mosquitoes
CORRECT ANSWER: A. A period of suspended development to survive unfavorable conditions
Rationale: Diapause is a genetically programmed state of dormancy that allows mosquitoes to survive
harsh conditions, such as the cold Alberta winter, either as eggs or as adult females.
Question 7: Which mosquito genus commonly overwinters in Alberta as a fertilized adult female?
A. Aedes
B. Culex
C. Culiseta
D. Anopheles
CORRECT ANSWER: C. Culiseta
Rationale: Species like Culiseta inornata overwinter as fertilized adult females in protected areas like
caves, culverts, or barns, emerging in early spring to take a blood meal and lay eggs.
,Question 8: How do floodwater mosquitoes (e.g., Aedes vexans) survive the winter in Alberta?
A. As larvae in deep, unfrozen water
B. As pupae in the mud
C. As eggs laid in moist soil that withstand freezing
D. As adult males in leaf litter
CORRECT ANSWER: C. As eggs laid in moist soil that withstand freezing
Rationale: Floodwater Aedes mosquitoes lay their eggs on moist soil above the waterline. These eggs
enter diapause and can survive freezing winter temperatures, hatching when flooded by spring
snowmelt or heavy rain.
Question 9: What is the primary food source for adult male mosquitoes?
A. Mammalian blood
B. Nectar and plant sugars
C. Other insects
D. Algae
CORRECT ANSWER: B. Nectar and plant sugars
Rationale: Both male and female mosquitoes feed on plant nectar and sugars for energy. Only female
mosquitoes require a blood meal, which provides the protein necessary for egg development.
Question 10: Why do female mosquitoes bite humans and animals?
A. For personal energy and sustenance
B. To obtain protein required for egg development
C. To transmit diseases intentionally
D. To defend their territory
CORRECT ANSWER: B. To obtain protein required for egg development
Rationale: Female mosquitoes require the proteins and iron found in blood to mature their eggs.
Without a blood meal, most species cannot produce viable eggs.
Question 11: What is the typical flight range of most mosquito species found in Alberta?
A. Less than 1 to 3 kilometers
B. 50 to 100 kilometers
C. 200 to 300 kilometers
D. They do not fly; they are wind-blown only
CORRECT ANSWER: A. Less than 1 to 3 kilometers
, Rationale: Most mosquitoes are weak fliers and typically stay within 1 to 3 kilometers of their breeding
site, although some species can be carried much farther by strong winds.
Question 12: During what time of day are Culex species most actively biting?
A. Early morning
B. Mid-day
C. Dusk and evening
D. They bite randomly throughout the 24-hour cycle
CORRECT ANSWER: C. Dusk and evening
Rationale: Culex species, including the primary West Nile Virus vector Culex tarsalis, are primarily
crepuscular and nocturnal, with peak biting activity occurring at dusk and into the evening.
Question 13: During what time of day are Aedes species (like Aedes vexans) most actively biting?
A. Only at midnight
B. Daytime, especially early morning and late afternoon
C. Only during heavy rain
D. They do not bite humans
CORRECT ANSWER: B. Daytime, especially early morning and late afternoon
Rationale: Many Aedes species are aggressive daytime biters, with peak activity often occurring in the
early morning and late afternoon or early evening.
Question 14: What does the term "autogeny" mean in mosquito biology?
A. The ability of a female to lay her first batch of eggs without a blood meal
B. The ability to fly long distances
C. The resistance to pesticide exposure
D. The process of laying eggs in salt water
CORRECT ANSWER: A. The ability of a female to lay her first batch of eggs without a blood meal
Rationale: Autogenous mosquitoes can utilize energy reserves stored from their larval stage to produce
their first batch of eggs without needing to take a blood meal first.
Question 15: How does ambient temperature affect mosquito development?
A. It has no effect on development time
B. Higher temperatures generally accelerate development up to a lethal threshold
C. Higher temperatures cause immediate diapause
D. Mosquitoes only develop in freezing temperatures
CORRECT ANSWER: B. Higher temperatures generally accelerate development up to a lethal threshold
