MICHIGAN MOSQUITO CONTROL 7F
CERTIFICATION EXAM PREP 2027
QUESTIONS AND ANSWERS
1. Which mosquito species is the primary vector for Eastern Equine Encephalitis (EEE) in
Michigan, typically found 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 in bird populations within specific swamp habitats.
2. In the context of Integrated Pest Management (IPM), what is the most effective long-term
solution for mosquito control?
A. Frequent ULV adulticiding
B. Increasing the dosage of larvicides
,C. Source reduction through habitat modification
D. Applying residual sprays to all vegetation
Answer: C
Conceptual Explanation: Source reduction, such as draining stagnant water or clearing
debris, permanently removes breeding sites, making it the most sustainable IPM strategy.
3. Which stage of the mosquito life cycle is known as the ‘tumbler’?
A. Larva
B. Pupa
C. Egg
D. Adult
Answer: B
Conceptual Explanation: The pupal stage is non-feeding but active, often called a tumbler
due to its rolling motion when disturbed.
4. Under Michigan Act 451, Part 83, what is the minimum distance required for a buffer zone
when applying pesticides near a public water intake?
A. 50 feet
B. 100 feet
C. 500 feet
, D. It depends on the specific label and local ordinances
Answer: D
Conceptual Explanation: While there are general guidelines, the pesticide label is the law,
and local regulations or specific site constraints dictate the buffer.
5. Which mosquito genus lays its eggs in ‘rafts’ on the water surface?
A. Aedes
B. Psorophora
C. Toxorhynchites
D. Culex
Answer: D
Conceptual Explanation: Culex and Culiseta mosquitoes typically lay their eggs in rafts
consisting of up to 300 eggs glued together.
6. Methoprene is a type of larvicide classified as a(n):
A. Organophosphate
B. Microbial agent
C. Surface film
D. Insect Growth Regulator (IGR)
Answer: D
