1. Which of the following best defines the primary objective of a Vector
Control Inspector in public health programs?
A. To design architectural sanitation systems for hospitals
B. To conduct financial audits of municipal health departments
C. To detect, prevent, and control vectors that transmit disease and
affect public health
D. To regulate food pricing in public markets
Correct Answer: C. The primary objective of a Vector Control
Inspector is to identify, manage, and reduce populations of disease-
carrying organisms such as mosquitoes and rodents to protect public
health.
2. Which organism is most commonly targeted in mosquito control
programs due to its role in disease transmission?
A. Honeybee
B. Anopheles mosquito
C. Earthworm
D. Ladybird beetle
, Correct Answer: B. The Anopheles mosquito is a major vector
responsible for transmitting malaria and is a key target in mosquito
control efforts.
3. In vector control operations, “larviciding” refers to:
A. Killing adult mosquitoes in flight
B. Eliminating mosquito breeding sites through construction
C. Applying chemical or biological agents to kill mosquito larvae
D. Sterilizing water treatment facilities
Correct Answer: C. Larviciding involves treating water sources where
mosquito larvae develop to interrupt their life cycle before
adulthood.
4. Which environmental condition most directly promotes mosquito
breeding?
A. Dry sandy soil
B. Stagnant standing water
C. High altitude rocky terrain
D. Frozen groundwater
Correct Answer: B. Mosquitoes require stagnant water bodies for egg
laying and larval development, making such environments ideal
breeding sites.
5. A key reason vector control inspectors monitor rodent populations is
because rodents:
A. Produce oxygen-depleting gases
B. Spread plant nutrients in soil
C. Act as reservoirs for zoonotic diseases
D. Improve urban drainage systems
Correct Answer: C. Rodents can carry and transmit zoonotic diseases
such as leptospirosis and plague, making their control essential for
public health.
, 6. Which personal protective equipment (PPE) is most appropriate during
pesticide application?
A. Formal office attire
B. Respirator, gloves, and protective clothing
C. Cotton casual wear only
D. Safety helmet only
Correct Answer: B. PPE such as respirators, gloves, and protective
clothing is necessary to prevent pesticide exposure and poisoning.
7. The term “vector” in public health refers to:
A. Any plant that causes allergies
B. Any animal capable of transmitting disease agents
C. Only bacteria in water systems
D. Any chemical pollutant in air
Correct Answer: B. A vector is any living organism, such as
mosquitoes or rodents, that can transmit disease pathogens to
humans or animals.
8. Which of the following is a common method used to monitor
mosquito populations?
A. Satellite imaging of forests
B. Larval dipping and trap collection
C. Soil chemical testing
D. Water pH neutralization
Correct Answer: B. Larval dipping and trap collection are standard
surveillance techniques used to estimate mosquito abundance and
distribution.
9. In integrated vector management, the term “habitat modification”
means:
A. Genetic modification of insects
B. Changing human diets to avoid disease
