1. What is the primary goal of Integrated Pest Management (IPM) in ornamental
plant production?
A. Eliminate every insect from the landscape
B. Apply pesticides on a fixed calendar schedule
C. Manage pests effectively while minimizing economic, environmental, and
health risks
D. Use the strongest available pesticide
Answer: C. Manage pests effectively while minimizing economic, environmental,
and health risks
Rationale: IPM combines monitoring, identification, cultural practices, biological
controls, and carefully selected chemical controls to manage pests while
reducing unnecessary pesticide use.
2. Which observation is most useful when diagnosing an ornamental plant
problem?
,A. The age of the pesticide sprayer
B. The pattern and distribution of symptoms on the plant
C. The color of the pesticide container
D. The brand of fertilizer previously used
Answer: B. The pattern and distribution of symptoms on the plant
Rationale: Symptom patterns can help distinguish insect injury, disease, nutrient
problems, environmental stress, and other causes.
3. Before treating an ornamental plant for an insect, the applicator should first:
A. Increase the pesticide rate
B. Mix two insecticides together
C. Correctly identify the pest
D. Apply pesticide to every plant nearby
Answer: C. Correctly identify the pest
Rationale: Accurate identification is essential because different pests require
different management strategies and some apparent pests may actually be
beneficial organisms.
4. Which insect group commonly has piercing-sucking mouthparts?
A. Butterflies
B. Beetles
C. Aphids
D. Caterpillars
Answer: C. Aphids
Rationale: Aphids have piercing-sucking mouthparts and feed on plant fluids,
often causing curling, distortion, or reduced plant vigor.
,5. Honeydew on leaves and nearby surfaces is commonly associated with:
A. Grasshoppers
B. Aphids, scales, and whiteflies
C. Earthworms
D. Leaf miners
Answer: B. Aphids, scales, and whiteflies
Rationale: Many sap-feeding insects excrete excess sugary fluid called
honeydew, which may support the growth of sooty mold.

A. Excess nitrogen only
B. Root-knot nematodes
C. Honeydew-producing insects
D. Mechanical pruning damage
Answer: C. Honeydew-producing insects
Rationale: Sooty mold commonly develops on the sugary honeydew produced by
certain sap-feeding insects.
7. Which pest is commonly associated with fine webbing on foliage?
A. Scale insects
B. Spider mites
C. Aphids
D. White grubs
Answer: B. Spider mites
Rationale: Spider mites may produce fine webbing, stippling, bronzing, and
premature leaf drop, particularly under hot, dry conditions.
, 8. A plant with stippled or speckled leaves may have an infestation of:
A. Slugs
B. Spider mites
C. Earthworms
D. Root-feeding beetles only
Answer: B. Spider mites
Rationale: Spider mite feeding damages individual plant cells and commonly
produces characteristic stippling or speckling on leaves.
9. Which insect stage is often responsible for chewing holes in ornamental
foliage?
A. Aphid nymph
B. Scale crawler
C. Caterpillar
D. Adult aphid
Answer: C. Caterpillar
Rationale: Caterpillars are larval forms of moths and butterflies and commonly
possess chewing mouthparts that damage leaves.
10. Why is scouting important in ornamental pest management?
A. It guarantees pesticide effectiveness
B. It eliminates the need for pest identification
C. It determines whether pests are present and whether management is justified
D. It replaces all cultural practices
Answer: C. It determines whether pests are present and whether management
is justified
