CAC Pest Management & Integrated Pest Management (IPM)

Question 1

What is the primary goal of Integrated Pest Management (IPM)?

Accepted Answer

Manage pests to economically acceptable levels using multiple strategies while minimizing risks

Answer

Eliminate all pest populations using maximum pesticide rates

Answer

Rely exclusively on biological control agents

Answer

Apply pesticides on a fixed calendar schedule

Question 2

The Economic Threshold (ET) in pest management is defined as the pest density at which:

Accepted Answer

Control actions must be taken to prevent pest populations from reaching the Economic Injury Level

Answer

Crop damage becomes visible to the naked eye

Answer

All pest activity should be recorded for future reference

Answer

The pest population has caused irreversible economic loss

Question 3

Which type of pest scouting method involves walking a field in a specific pattern to obtain representative pest population samples?

Accepted Answer

Systematic transect scouting

Answer

Random stratified sampling

Answer

Hot-spot sampling

Answer

Border row monitoring

Question 4

A Certified Agricultural Consultant finds aphid populations at 250 per plant on winter wheat. The economic threshold is 300 per plant. What is the most appropriate recommendation?

Accepted Answer

Continue monitoring closely as populations are below the economic threshold

Answer

Apply an insecticide immediately at the full label rate

Answer

Apply a biological control agent to eliminate all aphids

Answer

No further scouting is necessary since damage has not occurred

Question 5

Which of the following is an example of a cultural pest management practice?

Accepted Answer

Rotating crops to disrupt pest life cycles

Answer

Releasing Trichogramma wasps to parasitize pest eggs

Answer

Applying a contact insecticide during peak pest emergence

Answer

Installing pheromone traps to monitor adult moth populations

Question 6

What does the term 'action threshold' mean in the context of IPM decision-making?

Accepted Answer

The pest population density or damage level that triggers a management response

Answer

The level of pesticide concentration that kills 50% of a pest population

Answer

The point at which crop yield loss becomes irreversible

Answer

The maximum allowable pesticide residue on harvested crops

Question 7

Pheromone traps used in IPM programs are primarily used to:

Accepted Answer

Monitor pest population activity and determine timing of management interventions

Answer

Kill adult insects before they can reproduce

Answer

Attract and kill all life stages of target pests

Answer

Replace the need for field scouting entirely
