CCA - Certified Crop Advisor Integrated Pest Management Questions and Answers

Question 1

Which of the following best defines the Economic Threshold (ET) in an Integrated Pest Management (IPM) program?

Accepted Answer

The pest density at which control measures should be applied to prevent the pest population from reaching the Economic Injury Level.

Answer

The lowest pest population density that will cause economic damage.

Answer

The point at which pest damage is visible in the field, justifying the cost of scouting.

Answer

The maximum pest population that can be tolerated without any yield loss.

Question 2

A grower is experiencing significant corn rootworm damage despite rotating corn with soybeans. Some adult rootworms are observed laying eggs in the soybean field. Which cultural control practice would be most effective in this scenario to disrupt the pest life cycle?

Accepted Answer

Planting a different non-host crop, such as alfalfa or wheat, for at least one year.

Answer

Adjusting the corn planting date to be much earlier in the season.

Answer

Increasing the seeding rate of the subsequent corn crop to compensate for damage.

Answer

Applying a soil insecticide during soybean planting to target egg-laying adults.

Question 3

The release of mass-reared lady beetles to control an aphid population in a greenhouse is an example of which type of biological control?

Accepted Answer

Augmentative

Answer

Classical

Answer

Conservation

Answer

Competitive

Question 4

To effectively manage pesticide resistance, a key IPM strategy is to rotate pesticides with different modes of action (MOA). Why is this practice recommended?

Accepted Answer

It prevents the selection and buildup of resistant individuals within the pest population.

Answer

It ensures that all pesticides in a chemical family are used up before their expiration date.

Answer

It reduces the total amount of pesticide active ingredient applied to the field over a season.

Answer

It enhances the effectiveness of beneficial insects that may be present in the field.

Question 5

Which of the following is NOT considered a fundamental component of an Integrated Pest Management (IPM) program?

Accepted Answer

Scheduled, calendar-based pesticide applications.

Answer

Regular monitoring and scouting of pest populations.

Answer

Use of economic thresholds to guide control decisions.

Answer

Integration of multiple control tactics (cultural, biological, chemical).

Question 6

A Certified Crop Advisor scouts a field and identifies a pest population that is approaching the Economic Threshold. According to IPM principles, what is the most appropriate next step?

Accepted Answer

Evaluate and select an appropriate control measure to be implemented.

Answer

Wait until the population reaches the Economic Injury Level before taking action.

Answer

Immediately apply a broad-spectrum insecticide to prevent any further increase.

Answer

Discontinue scouting for the remainder of the season as the pest is now established.
