NYS PCO NYS PCO Integrated Pest Management 1 — Questions and Answers
Question 1: What is the foundation principle of Integrated Pest Management (IPM)?
- Using a combination of methods to manage pests with minimum environmental and health risk (Correct answer)
- Applying pesticides on a fixed calendar schedule
- Eliminating all pests immediately upon detection
- Using only biological control agents
Correct answer: Using a combination of methods to manage pests with minimum environmental and health risk
IPM is based on combining biological, cultural, physical, and chemical controls to manage pests at acceptable levels while minimizing risks.
Question 2: In an IPM program, the 'action threshold' refers to:
- The pest population level at which control measures are economically or aesthetically justified (Correct answer)
- The legal pesticide application rate on the label
- The point at which pest activity becomes visible to humans
- The number of traps required per 1,000 sq ft
Correct answer: The pest population level at which control measures are economically or aesthetically justified
The action threshold is the pest density at which intervention becomes necessary to prevent unacceptable damage or health risk, guiding treatment decisions.
Question 3: Exclusion, as an IPM strategy, involves:
- Sealing entry points to prevent pest access to a structure (Correct answer)
- Using traps to capture and remove pests
- Applying pesticides along the perimeter
- Removing food and water sources
Correct answer: Sealing entry points to prevent pest access to a structure
Exclusion uses physical barriers — caulking, door sweeps, screens, mesh — to prevent pests from entering a structure.
Question 4: Monitoring in IPM serves which primary purpose?
- To identify pest species, population size, and distribution before choosing control tactics (Correct answer)
- To apply pesticides on a schedule regardless of pest levels
- To document that treatments were performed for regulatory purposes
- To determine the chemical resistance of the pest population
Correct answer: To identify pest species, population size, and distribution before choosing control tactics
Regular monitoring through trapping, inspection, and sampling provides the data needed to identify pests accurately and make informed control decisions.
Question 5: Which IPM control method involves altering the environment to make it less conducive to pest survival?
- Cultural control (sanitation, habitat modification) (Correct answer)
- Chemical control
- Biological control
- Mechanical trapping
Correct answer: Cultural control (sanitation, habitat modification)
Cultural controls such as improving sanitation, eliminating harborage, and reducing moisture make environments inhospitable for pests.
Question 6: In the IPM hierarchy, pesticides are considered:
- A last resort used only when other methods are insufficient or impractical (Correct answer)
- The first response to any pest sighting
- The only reliable method for structural pests
- Prohibited in true IPM programs
Correct answer: A last resort used only when other methods are insufficient or impractical
IPM treats chemical pesticides as tools to be used when non-chemical strategies are insufficient, selecting the least-hazardous effective option.
