1. Which of the following best describes the primary goal of ornamental
pest control in commercial landscapes?
A. Eliminate all insect populations permanently from the landscape
B. Maintain plant health and aesthetic value while using integrated pest
management strategies
C. Apply pesticides on a fixed calendar schedule regardless of pest presence
D. Focus only on reducing pesticide costs for the applicator
Answer: B
Rationale: The primary goal of ornamental pest control is to protect plant
health and appearance while minimizing environmental impact through
integrated pest management (IPM), rather than eliminating all pests or
relying on routine pesticide applications.
2. In ornamental pest management, what is the most important first step
before selecting a control method?
,A. Applying a broad-spectrum insecticide immediately
B. Identifying the pest accurately and confirming its presence
C. Increasing irrigation to strengthen plants
D. Pruning all affected plant material
Answer: B
Rationale: Accurate pest identification is essential because effective
management decisions depend on knowing the exact pest species and its
biology.
3. Which pest management approach emphasizes combining cultural,
biological, and chemical controls?
A. Reactive pest control
B. Calendar-based spraying
C. Integrated Pest Management (IPM)
D. Mechanical eradication only
Answer: C
Rationale: IPM integrates multiple control methods in a coordinated way
to manage pest populations economically and sustainably.
4. Which of the following is a key characteristic of aphid damage on
ornamental plants?
A. Chewed leaf edges only
B. Honeydew accumulation and sooty mold formation
C. Root tunneling and soil disruption
D. Bark splitting on mature trees only
Answer: B
Rationale: Aphids feed on plant sap and excrete honeydew, which often
leads to sooty mold growth on plant surfaces.
, 5. What is the main reason pest thresholds are used in ornamental pest
control?
A. To ensure complete pest eradication
B. To determine when pest populations justify control measures
C. To increase pesticide application frequency
D. To reduce the need for plant inspections
Answer: B
Rationale: Thresholds help determine when pest levels are high enough to
cause unacceptable damage and require intervention.
6. Which type of insect undergoes complete metamorphosis?
A. Grasshoppers
B. Aphids
C. Beetles
D. True bugs
Answer: C
Rationale: Beetles undergo complete metamorphosis, with egg, larva,
pupa, and adult stages.
7. What is the primary function of surfactants in pesticide applications?
A. Increase pesticide toxicity
B. Improve spray coverage and leaf adhesion
C. Neutralize pesticide breakdown products
D. Reduce pesticide shelf life
Answer: B
Rationale: Surfactants reduce surface tension, helping sprays spread evenly
and stick to plant surfaces more effectively.
, 8. Which pest is commonly associated with fine webbing on ornamental
plants?
A. Whiteflies
B. Spider mites
C. Leaf miners
D. Scale insects
Answer: B
Rationale: Spider mites produce fine webbing and cause stippling damage
on leaves due to feeding activity.
9. What is a systemic insecticide designed to do?
A. Remain only on the plant surface
B. Penetrate soil but not plants
C. Be absorbed and move within plant tissues
D. Kill only contact-exposed insects immediately
Answer: C
Rationale: Systemic insecticides are absorbed by plants and distributed
internally, controlling pests that feed on plant tissues.
10. Which environmental condition most favors fungal disease
development in ornamentals?
A. Hot, dry, windy conditions
B. Cool, dry soil conditions
C. Warm, humid conditions with prolonged leaf wetness
D. Freezing temperatures with low humidity
Answer: C
Rationale: Fungal pathogens thrive in warm, humid environments where
moisture remains on plant surfaces for extended periods.
