Question 1

In a rotation crop field, the farmer alternates corn with soybeans each season. How does this practice support IPM?

Accepted Answer

It disrupts pest life cycles by removing the host crop

Answer

Crop rotation disrupts the host-pest cycle because pests adapted to one crop do not persist at damaging levels when a non-host crop is planted.

Question 2

Which type of pheromone trap is most commonly used in IPM monitoring programs for Lepidoptera?

Accepted Answer

Sex pheromone (sex attractant) trap

Answer

Sex pheromone traps attract adult male moths to a lure containing synthetic female sex pheromone, used to monitor adult flight activity and population levels.

Question 3

A pest manager discovers that a population of houseflies is no longer controlled effectively by a pyrethroid that previously worked well. What IPM strategy helps address this situation?

Accepted Answer

Rotating to a pesticide with a different mode of action

Answer

Rotating pesticides with different modes of action is the standard resistance management strategy, as it prevents selection pressure from accumulating on a single resistance mechanism.

Question 4

What is 'classical biological control'?

Accepted Answer

Introduction of exotic natural enemies from the pest's native range to a new area

Answer

Classical biological control involves importing and releasing natural enemies from the pest's area of origin to provide long-term, self-sustaining suppression in the new range.

Question 5

Which of the following is an example of a physical/mechanical IPM control method for stored product pests?

Accepted Answer

Using modified atmosphere (CO2 or N2) to kill insects in sealed storage

Answer

Modified atmosphere treatments use elevated CO2 or nitrogen to create an oxygen-deficient environment that kills stored product insects without chemical residues.
