Introduction
This comprehensive practice examination is designed to prepare candidates for the Connecticut Category 7F
Mosquito and Biting Flies Pest Control certification. The assessment evaluates both foundational knowledge and
practical decision-making skills required for safe and effective vector management. It covers a broad range of
topics, including mosquito biology, surveillance techniques, integrated pest management, pesticide application,
and environmental protection. The exam structure features multiple-choice questions and scenario-based
problems that emphasize real-world application, regulatory compliance, and ethical conduct. This resource is
intended to build proficiency and confidence for successful completion of the official Category 7F licensing
examination.
,SECTION ONE: QUESTIONS 1–100
1. A technician is conducting a routine inspection for mosquito breeding sites in a suburban neighborhood.
Which action is the MOST critical first step in an Integrated Pest Management (IPM) program for mosquito
control?
A. Apply a broad-spectrum adulticide to all properties in the area.
B. Inspect for and eliminate or manage all potential standing water sources.
C. Install a network of UV light traps throughout the community.
D. Schedule weekly applications of larvicide to all catch basins.
🟢 Correct Answer: B
🔴 RATIONALE: The foundation of IPM is prevention, which begins with source reduction. Eliminating or
managing standing water disrupts the mosquito life cycle at its source, preventing larvae from developing into
adults. Chemical controls (adulticides) are a reactive measure and should only be used after surveillance and
source reduction have been implemented. UV traps have limited efficacy for mosquito control and are not a
primary IPM strategy .
2. Which mosquito genus is the PRIMARY vector for West Nile Virus (WNV) in Connecticut?
A. Aedes
B. Anopheles
C. Culex
D. Psorophora
🟢 Correct Answer: C
,🔴 RATIONALE: Culex mosquitoes, particularly Culex pipiens, are the primary enzootic and bridge vectors for
West Nile Virus in the northeastern United States. They primarily feed on birds, maintaining the virus in the bird
population, and can transmit it to humans and other mammals. Aedes species are associated with diseases like
Zika, dengue, and chikungunya, while Anopheles is the primary vector for malaria .
3. A technician observes mosquito larvae resting parallel to the water surface during a pond inspection. This
behavior is characteristic of which genus?
A. Aedes
B. Culex
C. Anopheles
D. Culiseta
🟢 Correct Answer: C
🔴 RATIONALE: Anopheles larvae are unique in that they lack a breathing siphon and lie horizontally or parallel
to the water surface to breathe. In contrast, larvae of genera like Aedes, Culex, and Culiseta possess a siphon
and hang at an angle from the surface to obtain air. This is a key diagnostic feature for identifying mosquito
larvae in the field .
4. What is the legal status of a pesticide label according to federal and state regulations?
A. An informational guide for safe handling and storage.
B. A binding legal document with enforceable instructions.
C. A set of recommendations that applicators may adapt based on conditions.
D. A manufacturer's warranty for product performance.
🟢 Correct Answer: B
, 🔴 RATIONALE: The pesticide label is the law. It is a legally enforceable document that specifies approved uses,
application rates, safety precautions, personal protective equipment (PPE), and environmental restrictions.
Applicators are legally required to follow all instructions on the label. Failure to do so constitutes a violation of
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and state regulations .
5. A technician is preparing to treat a large number of catch basins in a municipal area. Which formulation is
MOST commonly used for sustained larval mosquito control in these habitats?
A. Emulsifiable concentrate (EC)
B. Granular Bacillus thuringiensis israelensis (Bti)
C. Slow-release briquets containing methoprene or Bti
D. Ultra-Low Volume (ULV) pyrethroid sprays
🟢 Correct Answer: C
🔴 RATIONALE: Slow-release briquets (e.g., Altosid, VectoBac) are ideally suited for catch basins. They provide a
continuous release of the active ingredient (an insect growth regulator like methoprene or a biological larvicide
like Bti) over a period of weeks, ensuring larvae are controlled as they develop in the stagnant water. Granular
formulations can wash away, and ULV sprays are adulticides, not larvicides .
6. Which federal law establishes the comprehensive framework for pesticide regulation, including
registration, labeling, and use?
A. The Clean Water Act (CWA)
B. The Occupational Safety and Health Act (OSHA)
C. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
D. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
