Question 1

What is the foundational principle of Integrated Pest Management (IPM) as applied to landscape plants?

Accepted Answer

Use a combination of cultural, biological, mechanical, and chemical controls to manage pests with minimal environmental impact

Answer

IPM combines multiple control strategies to manage pest populations below economic or aesthetic thresholds while minimizing environmental and human health risks.

Question 2

What is an 'action threshold' in an IPM program for landscape plants?

Accepted Answer

The pest population or damage level at which management action becomes necessary

Answer

The action threshold is the pest level at which economic or aesthetic damage justifies implementing a management strategy to prevent further harm.

Question 3

Which category of insects feeds on plant juices by piercing plant tissue and sucking phloem or xylem sap?

Accepted Answer

Sucking/piercing insects

Answer

Sucking/piercing insects such as aphids, scale, and spider mites use specialized mouthparts to extract plant sap, causing wilting, yellowing, and distortion.

Question 4

What is the role of a 'beneficial insect' in a landscape IPM program?

Accepted Answer

To serve as a natural enemy that suppresses pest populations

Answer

Beneficial insects such as ladybugs, lacewings, and parasitic wasps are natural enemies that suppress pest populations through predation or parasitism.

Question 5

When scouting for pests in a landscape, what is the primary purpose of regular monitoring visits?

Accepted Answer

To identify pest species, population levels, and damage before they exceed action thresholds

Answer

Regular scouting allows early detection of pest problems so managers can respond before populations exceed thresholds and cause significant damage.
