MICHIGAN MOSQUITO CONTROL 7F
CERTIFICATION STUDY GUIDE EXAM
QUESTIONS AND ANSWERS
1. Which mosquito genus is uniquely characterized by larvae that attach to the roots of
submerged aquatic plants to breathe?
A. Aedes
B. Coquillettidia
C. Culex
D. Anopheles
Answer: B
Conceptual Explanation: Coquillettidia perturbans larvae and pupae possess a specialized
respiratory siphon designed to pierce the vascular tissues of aquatic plants to obtain
oxygen.
2. Which of the following is the primary vector of Eastern Equine Encephalitis (EEE) in the
bird-to-bird cycle in Michigan?
A. Culex pipiens
,B. Aedes vexans
C. Culiseta melanura
D. Anopheles quadrimaculatus
Answer: C
Conceptual Explanation: Culiseta melanura is the primary enzootic vector of EEE,
maintaining the virus among bird populations in hardwood swamps.
3. At what stage of the mosquito life cycle is the insect non-feeding and highly mobile in the
water?
A. Egg
B. Larva
C. Adult
D. Pupa
Answer: D
Conceptual Explanation: The pupal stage is a non-feeding, transitional stage where the
mosquito is active (tumblers) but does not consume nutrients.
4. In Michigan, which agency is responsible for the certification of pesticide applicators in
category 7F?
A. Department of Natural Resources (DNR)
B. Michigan Department of Agriculture and Rural Development (MDARD)
, C. Environmental Protection Agency (EPA)
D. Department of Environment, Great Lakes, and Energy (EGLE)
Answer: B
Conceptual Explanation: MDARD regulates and certifies pesticide applicators under the
Natural Resources and Environmental Protection Act, Part 83.
5. What is the optimum droplet size range (Volume Median Diameter) for Ultra-Low Volume
(ULV) adulticiding applications?
A. 0.1 to 1 micron
B. 50 to 100 microns
C. 100 to 200 microns
D. 5 to 20 microns
Answer: D
Conceptual Explanation: ULV applications require droplets between 5-20 microns to
remain airborne and maximize contact with flying mosquitoes.
6. Which mosquito species is commonly known as the ‘Northern House Mosquito’ and a
primary vector for West Nile Virus?
A. Aedes albopictus
B. Aedes triseriatus
C. Culex pipiens
