1. What mosquito species obtains oxygen through the roots of plants?
• A) Aedes vexans
• B) Aedes trivittatus
• C) Coquillettidia perturbans
• D) Culex tarsalis
Correct Answer: C) Coquillettidia perturbans
Expert Rationale: Unlike most mosquitoes that breathe atmospheric air through a
siphon, Coquillettidia perturbans larvae attach their modified siphon to aquatic
plant roots to obtain oxygen. This unique adaptation makes them difficult to
control with conventional larvicides.
2. How many instar stages does a mosquito go through?
• A) 1
• B) 2
• C) 3
• D) 4
Correct Answer: D) 4
Expert Rationale: Mosquitoes undergo four larval instars, molting between each
stage. The fourth instar then pupates. This is a fundamental concept in
entomology and mosquito control.
3. The life cycle stages of a mosquito are?
• A) Pupa, larva, egg, adult
• B) Egg, larva, pupa, adult
• C) Egg, instar, pupa, adult
, • D) Instar, larva, adult, pupa
Correct Answer: B) Egg, larva, pupa, adult
Expert Rationale: Mosquitoes undergo complete metamorphosis
(holometabolous development). The correct sequential order is egg → larva (four
instars) → pupa → adult.
4. Why do female mosquitoes take a blood meal?
• A) to produce eggs
• B) to feed/get nourishment
• C) to transmit disease
• D) to feed young
Correct Answer: A) to produce eggs
Expert Rationale: Female mosquitoes require proteins and iron found in blood for
egg development. Males do not take blood meals; both sexes feed on nectar for
energy. Disease transmission is an incidental consequence, not a purpose.
5. About how many species of mosquito are known to occur in Minnesota?
• A) 50
• B) 100
• C) 500
• D) 1000
Correct Answer: A) 50
Expert Rationale: Minnesota has approximately 50 recorded mosquito species.
While there are over 3,000 species worldwide, the state's cooler climate limits
diversity.
6. What type of sites do Culex mosquitoes prefer to lay eggs?
, • A) grassy areas
• B) temporary or permanent pools of water
• C) moist soil
• D) dry soil areas that usually flood
Correct Answer: B) temporary or permanent pools of water
Expert Rationale: Culex species prefer organically rich, stagnant or polluted water
bodies such as catch basins, storm drains, and permanent or semi-permanent
pools. They often lay eggs in rafts on the water surface.
7. Where do mosquitoes rest during the day?
• A) breeding sites
• B) structures
• C) harborage
• D) None of the above
Correct Answer: C) harborage
Expert Rationale: "Harborage" refers to sheltered areas where mosquitoes rest
during daylight hours, such as dense vegetation, under bridges, in culverts, or
inside animal burrows.
8. The "cattail mosquito" is also known as?
• A) Culex tarsalis
• B) Aedes vexans
• C) Aedes triseriatus
• D) Coquillettidia perturbans
Correct Answer: D) Coquillettidia perturbans
Expert Rationale: Coquillettidia perturbans is commonly called the cattail
