ANSWERS GRADED A+ WITH RATIONALES
1. Using barriers (e.g., screens, seals) to prevent pests from entering an area is an example of
which type of pest management method?
A. Biological
B. Mechanical
C. Genetic
D. Regulatory
o Rationale: Mechanical controls physically exclude or remove pests.
2. Plant varieties that are naturally resistant to insect feeding exemplify which pest management
method?
A. Biological
B. Genetic
C. Regulatory
D. Mechanical
o Rationale: Genetic methods use host resistance bred into plants.
3. Modifying the environment to enhance natural enemies (e.g., banker plants) is a true
statement about:
A. Physical control
B. Chemical control
C. Biological control
D. Genetic control
o Rationale: Biological control promotes predators and parasitoids.
4. Sealing cracks and crevices in buildings falls under which control method?
A. Physical
B. Genetic
C. Biological
D. Regulatory
o Rationale: Physical (mechanical) controls include exclusion tactics.
5. Cultural control practices aim to:
A. Release foreign predators
B. Use synthetic pesticides
C. Reduce pest establishment, reproduction, and survival
D. Sterilize seeds
,ESTUDYR
o Rationale: Cultural methods alter cropping or sanitation to suppress pests.
6. Monitoring pests at ports of entry (airports, seaports) is an example of:
A. Chemical
B. Genetic
C. Regulatory
D. Physical
o Rationale: Regulatory controls prevent pest introduction through inspections.
7. The goal of Integrated Pest Management (IPM) is to:
A. Eliminate every pest
B. Use only chemical methods
C. Prevent pests from reaching damaging levels
D. Maximize pesticide use
o Rationale: IPM focuses on long-term, sustainable pest suppression.
8. Which is a preventative pest management strategy?
A. Planting weed-free seed
B. Releasing predators post-infestation
C. Spraying after outbreak
D. Broadcasting pesticides
o Rationale: Preventative tactics act before pests arrive or establish.
9. Action thresholds in IPM refer to:
A. Pest levels where control must begin immediately
B. The pest density at which control measures are warranted
C. Zero-tolerance levels
D. Economic injury level
o Rationale: Thresholds guide when management becomes cost-effective.
10. Continual use of pesticides from the same chemical class will:
A. Prevent resistance
B. Increase the likelihood of resistance
C. Degrade pests faster
D. Improve control longevity
o Rationale: Repeated selection pressure favors resistant phenotypes.
11. Which statement about FIFRA is false?
A. It provides the federal framework for pesticide regulation.
B. It prevents states from enacting more stringent pesticide laws.
, ESTUDYR
C. It requires registration of all pesticides.
D. It mandates proper labeling.
o Rationale: States may impose stricter requirements than federal standards.
12. Under federal law, trained and certified applicators may:
A. Apply Restricted Use Pesticides (RUPs)
B. Mix RUPs without supplementary training
C. Apply and supervise RUP applications
D. Be exempt from endangered species bulletins
o Rationale: Certification authorizes handling of higher-risk products.
13. The purpose of pesticide registration is to:
A. Limit market competition
B. Ensure no unreasonable risk to human health or the environment
C. Eliminate residues entirely
D. Regulate packaging designs
o Rationale: EPA evaluates safety and efficacy before approving products.
14. Which statement about pesticide registration is true?
A. First-time violators always face civil penalties.
B. Devices need not be registered.
C. Approved labels have the force of law.
D. Only active ingredients are regulated.
o Rationale: Labels legally define allowable uses and precautions.
15. EPA establishes tolerances based on:
A. Anticipated sales volume
B. Independent research only
C. Toxicity and breakdown properties
D. Manufacturer claims
o Rationale: Tolerances reflect risk assessment of residues on food.
16. Under federal law, it is unlawful to:
A. Supervise trainees applying RUPs
B. Deface or remove pesticide labels
C. Maintain employee training records
D. Use EPA-approved PPE
o Rationale: Label integrity is critical for safe use instructions.
