In a rotation crop field, the farmer alternates corn with soybeans each season. How does this practice support IPM?
Answer: It disrupts pest life cycles by removing the host crop
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.
Which type of pheromone trap is most commonly used in IPM monitoring programs for Lepidoptera?
Answer: Sex pheromone (sex attractant) trap
Sex pheromone traps attract adult male moths to a lure containing synthetic female sex pheromone, used to monitor adult flight activity and population levels.
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?
Answer: Rotating to a pesticide with a different mode of action
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.
What is 'classical biological control'?
Answer: Introduction of exotic natural enemies from the pest's native range to a new area
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.
Which of the following is an example of a physical/mechanical IPM control method for stored product pests?
Answer: Using modified atmosphere (CO2 or N2) to kill insects in sealed storage
Modified atmosphere treatments use elevated CO2 or nitrogen to create an oxygen-deficient environment that kills stored product insects without chemical residues.
In urban IPM, 'Integrated Vegetation Management' (IVM) most commonly applies to which setting?
Answer: Utility rights-of-way and transportation corridors
IVM is primarily used along power lines, roadsides, and pipeline rights-of-way to selectively maintain low-growing, stable plant communities that resist pest vegetation.
What role does 'record keeping' play in an IPM program?
Answer: It provides historical data to evaluate program effectiveness and refine future decisions
Records of pest counts, treatments, and outcomes allow managers to analyze trends, evaluate tactic effectiveness, and make data-driven improvements to the IPM program.
