SECTION 1 — Integrated Pest Management (IPM)
1. What is the primary goal of Integrated Pest Management (IPM)?
Answer: To manage pest populations while minimizing risks to humans, wildlife, and the environment.
Explanation:
IPM focuses on controlling pests to acceptable levels rather than eliminating them completely. This approach reduces
environmental damage and pesticide overuse.
Memory Tip:
IPM = Manage pests, not eliminate them.
2. What term describes the number of pests or level of plant damage at which control measures should
begin?
Answer: Economic Threshold
Explanation:
The economic threshold is the pest population level at which action must be taken to prevent the population from reaching the
economic injury level.
Memory Tip:
Threshold = Trigger point for action
, 3. Which characteristic correctly describes insects?
Answer: They have three pairs of jointed legs.
Explanation:
All insects have six legs attached to the thorax and three body regions: head, thorax, and abdomen.
Memory Tip:
Insects = 6 legs
4. What life cycle represents incomplete metamorphosis?
Answer: Egg → Nymph → Adult
Explanation:
Insects with incomplete metamorphosis lack a pupal stage and the young resemble small adults.
Examples: aphids, grasshoppers.
5. What disease results from unfavorable environmental conditions rather than pathogens?
Answer: Noninfectious Disease
Explanation:
These diseases are caused by environmental stress such as:
● temperature extremes
● poor soil conditions
● fertilizer injury
● pesticide damage
SECTION 2 — Weed Management
6. What is the first step in developing a weed control program?
Answer: Identify the weed (scouting).
Explanation:
Correct identification ensures the appropriate herbicide or control method is used.
Memory Tip:
Control begins with scouting.
7. How do broadleaf weeds differ from grasses?
Answer: They have net-like leaf veins rather than parallel veins.
