Connecticut Category 7F Mosquito & Biting Flies Exam — MCQ Practice Batch 5 (201–250)
201. Which mosquito surveillance finding most strongly indicates an imminent arbovirus outbreak?
A. Low mosquito density with no virus detected
B. High vector abundance combined with positive viral testing
C. Dry weather conditions only
D. Decreased trap captures over time
Answer: B
Rationale: Outbreak risk increases when both mosquito populations and virus presence are high.

202. What is the primary purpose of sentinel chicken flocks in mosquito programs?
A. Reduce mosquito breeding
B. Detect early virus transmission in an area
C. Increase pesticide resistance
D. Replace mosquito trapping
Answer: B
Rationale: Sentinel chickens help detect arbovirus activity like West Nile virus early.
203. Which mosquito genus is most commonly associated with human-biting nuisance in urban parks?
A. Culex
B. House fly
C. Blow fly
D. Fruit fly
, Page 3 of 175
Answer: A
Rationale: Culex mosquitoes commonly bite humans in urban environments.
204. What is the primary purpose of seasonal mosquito abundance forecasting?
A. Increase pesticide use
B. Predict peak mosquito activity periods for planning control
C. Eliminate surveillance
D. Replace larval control
Answer: B
Rationale: Forecasting helps time interventions efficiently.
205. Which environmental factor most strongly influences mosquito egg diapause?
A. Soil color
B. Temperature and photoperiod changes
, Page 4 of 175
C. Wind speed
D. Water depth only
Answer: B
Rationale: Seasonal cues like temperature and daylight trigger dormancy.
206. What is the primary purpose of larval habitat productivity ranking?
A. Increase spraying everywhere equally
B. Prioritize high-yield breeding sites for control
C. Eliminate surveillance data
D. Reduce field work
Answer: B
Rationale: Ranking improves efficiency by targeting productive habitats.
