1. A public health pesticide applicator is preparing to treat an area for
mosquitoes near a residential community. Which factor is MOST important
before selecting a pesticide product?
A. The color of the pesticide container
B. The product advertising claims
C. The target mosquito species and labeled use site
D. The cost of the pesticide per gallon
Correct Answer: C
Rationale: The pesticide label is the law, and proper selection requires matching
the pesticide to the specific pest species, application site, and public health
objective. Using a product because of cost or marketing claims can result in
ineffective control, environmental contamination, or illegal pesticide use.
2. The primary goal of public health pest control programs is to:
A. Eliminate all insects from an environment
B. Reduce pests that threaten human health to acceptable levels
,C. Increase pesticide application frequency
D. Replace sanitation practices with chemical control
Correct Answer: B
Rationale: Public health pest management focuses on reducing disease vectors
and nuisance pests to levels that protect human health. Complete elimination is
usually unrealistic and unnecessary. Integrated approaches combine prevention,
monitoring, sanitation, and carefully selected pesticide applications.
3. Which mosquito life stage is generally targeted by larvicides?
A. Adult mosquito
B. Egg only
C. Pupal stage only
D. Immature aquatic stages
Correct Answer: D
Rationale: Larvicides are designed to control immature mosquito stages that
develop in water. Targeting larvae reduces future adult populations and is often
more efficient than relying only on adult mosquito control.
4. A pesticide label states that the product may only be applied by certified
applicators. This means:
A. Anyone may apply it if wearing gloves
B. Only properly certified individuals may legally apply it
C. It may only be applied indoors
D. It does not require reading the label
Correct Answer: B
Rationale: Restricted-use and certain professional pesticide products require
application by certified personnel because they present greater risks or require
,specialized knowledge. Certification ensures applicators understand safety,
calibration, environmental protection, and legal requirements.
5. Which practice BEST reduces pesticide exposure to the public during mosquito
adulticide applications?
A. Applying during peak pedestrian activity
B. Increasing the application rate above the label
C. Following label directions and timing applications appropriately
D. Ignoring weather conditions
Correct Answer: C
Rationale: Proper timing, correct rates, and compliance with the label reduce
unnecessary exposure while maintaining effectiveness. Public health
applications must balance pest suppression with protection of residents,
workers, and the environment.
6. Integrated Pest Management (IPM) emphasizes:
A. Using pesticides as the only control method
B. Combining multiple pest management strategies
C. Eliminating all beneficial organisms
D. Applying pesticides on a fixed calendar schedule regardless of conditions
Correct Answer: B
Rationale: IPM combines monitoring, sanitation, biological controls, cultural
practices, exclusion, and targeted pesticide use when necessary. This approach
improves effectiveness and reduces pesticide risks.
7. A mosquito surveillance program commonly uses traps primarily to:
, A. Increase mosquito breeding
B. Determine mosquito population levels and species presence
C. Replace all pesticide applications
D. Attract predators
Correct Answer: B
Rationale: Surveillance data allows public health professionals to identify
mosquito species, estimate population density, detect disease risks, and
determine when control measures are justified.
8. Which personal protective equipment (PPE) requirement should always be
followed first?
A. The applicator’s personal preference
B. The pesticide label instructions
C. The equipment manufacturer’s advertisement
D. Advice from an untrained observer
Correct Answer: B
Rationale: The pesticide label legally specifies required PPE because
requirements vary by chemical formulation and toxicity. Applicators must follow
label directions exactly.
9. A pesticide applicator notices strong wind conditions before an outdoor
application. The BEST action is to:
A. Increase spray pressure
B. Apply immediately before conditions worsen
C. Delay application until conditions are acceptable
D. Remove protective equipment
Correct Answer: C
