MICHIGAN MOSQUITO CONTROL 7F
PROFESSIONAL CERTIFICATION
EXAM QUESTIONS AND ANSWERS
1. Which type of metamorphosis do mosquitoes undergo, characterized by four distinct
stages?
A. Hemimetabolous
B. Paurometabolous
C. Ametabolous
D. Holometabolous
Answer: D
Conceptual Explanation: Mosquitoes undergo complete metamorphosis
(holometabolous), which includes the egg, larva, pupa, and adult stages.
2. Which mosquito genus is primarily known for transmitting Eastern Equine Encephalitis
(EEE) among bird populations in Michigan?
A. Culex
B. Culiseta
,C. Aedes
D. Anopheles
Answer: B
Conceptual Explanation: Culiseta melanura is the primary enzootic vector of EEE,
maintaining the virus in bird populations in hardwood swamps.
3. What is the primary target of an IGR (Insect Growth Regulator) such as methoprene?
A. The nervous system of adult mosquitoes
B. The respiratory system of larvae
C. The physiological development of larvae preventing adult emergence
D. The ability of females to produce eggs
Answer: C
Conceptual Explanation: Methoprene is a juvenile hormone mimic that prevents larvae
from successfully molting into the adult stage.
4. In Ultra Low Volume (ULV) applications, the Volume Median Diameter (VMD) of droplets
should typically be within which range?
A. 5 to 20 microns
B. 50 to 100 microns
C. 100 to 200 microns
, D. 0.1 to 1 micron
Answer: A
Conceptual Explanation: ULV applications require tiny droplets (5-20 microns) to remain
airborne longer and increase the probability of contacting flying mosquitoes.
5. Which Michigan law regulates the application of pesticides and the certification of
applicators?
A. Act 247, Part 5
B. The Clean Water Act
C. FIFRA Section 18
D. Act 451, Part 83
Answer: D
Conceptual Explanation: Natural Resources and Environmental Protection Act, PA 451,
Part 83, is the primary state law governing pesticide use in Michigan.
6. Culex pipiens, a primary vector for West Nile Virus, typically overwinters in which stage?
A. Egg
B. Larva
C. Adult
D. Pupa
