1. Which is the primary goal of integrated pest management (IPM)?
A. Eliminate all pests completely
B. Use only chemical pesticides
C. Reduce pest populations to acceptable levels
D. Increase pesticide resistance
Answer: C
Rationale: IPM focuses on keeping pest populations below economic
injury levels rather than total eradication.
2. Which pest control method uses natural predators?
A. Cultural control
B. Biological control
C. Chemical control
, D. Mechanical control
Answer: B
Rationale: Biological control uses living organisms such as predators,
parasites, or pathogens to control pests.
3. What does LD50 represent in toxicology?
A. Lethal dose for 50% of a population
B. Lowest dose detected
C. Liquid dilution 50%
D. Label direction 50
Answer: A
Rationale: LD50 is the dose required to kill 50% of a test population
and measures acute toxicity.
4. Which pesticide application method minimizes drift?
A. Aerial spraying
B. High-pressure spraying
C. Low-pressure ground spraying
D. Fogging
Answer: C
Rationale: Low-pressure ground applications reduce droplet drift
compared to aerial or high-pressure methods.
5. What is a key advantage of crop rotation?
A. Increases pesticide resistance
B. Reduces soil fertility
, C. Breaks pest life cycles
D. Increases pest populations
Answer: C
Rationale: Crop rotation disrupts pest reproduction cycles by
changing host availability.
6. Which insect growth stage is most resistant to pesticides?
A. Egg
B. Larva
C. Adult
D. Nymph
Answer: A
Rationale: Egg stages are often protected by shells or coverings
making them less susceptible.
7. What is the function of a surfactant in pesticides?
A. Kill pests directly
B. Increase pesticide spread and adhesion
C. Reduce toxicity
D. Act as fertilizer
Answer: B
Rationale: Surfactants improve wetting and spreading of spray
solutions on plant surfaces.
8. Which pest control method involves removing pest habitats?
A. Chemical control
, B. Mechanical control
C. Cultural control
D. Genetic control
Answer: C
Rationale: Cultural control modifies the environment to make it less
suitable for pests.
9. What is pesticide resistance?
A. Pest immunity to predators
B. Pest ability to survive pesticide exposure
C. Chemical breakdown of pesticides
D. Soil contamination
Answer: B
Rationale: Resistance occurs when pests survive doses that would
normally kill them.
10. Which is a sign of pesticide poisoning?
A. Increased appetite
B. Headache and nausea
C. Improved vision
D. Weight gain
Answer: B
Rationale: Common symptoms include nausea, dizziness, and
headaches after exposure.
