MICHIGAN MOSQUITO CONTROL 7F
FINAL EXAM STUDY GUIDE
QUESTIONS AND ANSWERS
1. Which mosquito species is the primary enzootic vector of Eastern Equine Encephalitis (EEE)
in Michigan, primarily feeding on birds in hardwood swamps?
A. Aedes vexans
B. Culiseta melanura
C. Culex pipiens
D. Anopheles quadrimaculatus
Answer: B
Conceptual Explanation: Culiseta melanura is the primary enzootic vector of EEE,
maintaining the virus cycle in bird populations within specific swamp habitats.
2. Which unique biological feature allows Coquillettidia perturbans to remain submerged
throughout its larval and pupal stages?
A. Cutaneous respiration through the integument
B. Modified siphon used to pierce aquatic plant tissues
,C. Large internal oxygen storage bladders
D. Symbiotic relationship with algae for oxygen production
Answer: B
Conceptual Explanation: Coquillettidia perturbans larvae and pupae possess a specialized
siphon or respiratory trumpets that pierce the vascular tissue of aquatic plants to obtain
oxygen.
3. In Michigan, which regulation governs the requirements for pesticide applicator
certification and the use of pesticides?
A. Regulation 637
B. Act 451, Part 83
C. FIFRA Section 18
D. Act 204, Part 12
Answer: B
Conceptual Explanation: Natural Resources and Environmental Protection Act, Act 451,
Part 83, is the primary law governing pesticide application and certification in Michigan.
4. What is the primary mode of action for the biological larvicide Bacillus thuringiensis
israelensis (Bti)?
A. Interference with chitin synthesis during molting
B. Neurotoxic paralysis of the larval central nervous system
, C. Destruction of the larval midgut lining after ingestion
D. Asphyxiation by creating a film on the water surface
Answer: C
Conceptual Explanation: Bti produces protein crystals that, when ingested, are broken
down in the alkaline gut of the mosquito larva, destroying the gut wall.
5. Under Michigan Regulation 637, what is the mandatory requirement regarding the
‘Registry of Physically Hypersensitive Individuals’?
A. Applicators must avoid all spraying within 1 mile of these individuals.
B. Individuals must provide a doctor’s note every 30 days to remain on the list.
C. Applicators must notify registered individuals before a pesticide application occurs on
adjacent properties.
D. Pesticide use is strictly prohibited in the entire zip code of a registered individual.
Answer: C
Conceptual Explanation: Regulation 637 requires commercial applicators to notify
individuals on the registry before applying pesticides to properties adjacent to the
registered individual’s property.
6. Which mosquito genus is characterized by larvae that hang at an angle from the water
surface and adults with blunt abdomens?
A. Culex
