MICHIGAN MOSQUITO CONTROL 7F
FINAL EXAM QUESTIONS AND
ANSWERS 2026/2027 QUESTIONS AND
ANSWERS
1. Which biological stage of the mosquito is generally the most effective target for large-scale
population reduction in integrated pest management?
A. Egg
B. Pupa
C. Larva
D. Adult
Answer: C
Conceptual Explanation: The larval stage is often the most effective to target because
larvae are concentrated in specific aquatic habitats, making them easier to treat than
widely dispersed adults.
,2. Which mosquito genus is primarily responsible for the transmission of Eastern Equine
Encephalitis (EEE) in Michigan?
A. Culex
B. Culiseta
C. Anopheles
D. Aedes
Answer: B
Conceptual Explanation: Culiseta melanura is the primary enzootic vector of EEE,
maintaining the virus in bird populations, while other species bridge the virus to humans.
3. In the context of Ultra-Low Volume (ULV) applications, what does VMD stand for?
A. Volatile Material Diffusion
B. Velocity Maximum Density
C. Variable Mist Distribution
D. Volume Median Diameter
Answer: D
Conceptual Explanation: Volume Median Diameter (VMD) is a standard measure of
droplet size; it represents the droplet diameter where half the volume of the spray is
contained in droplets smaller than this value.
, 4. Under Michigan Act 451, Part 83, what is the retention requirement for commercial
pesticide application records?
A. 1 year
B. 5 years
C. 3 years
D. 10 years
Answer: C
Conceptual Explanation: Michigan law requires commercial applicators to maintain
records for at least three years for routine applications.
5. Which of the following describes the ‘instar’ in mosquito development?
A. The chemical signal used to attract mates
B. The specialized breathing tube of the pupa
C. The period between larval molts
D. The resting state of an adult mosquito
Answer: C
Conceptual Explanation: Larvae go through four developmental stages called instars,
shedding their exoskeleton between each stage.
6. What is the primary mode of action for Methoprene when used in mosquito control?
A. Neurotoxicity via sodium channel blockage
