Final answer:
The three main components of an effective pest prevention program in the context of Integrated Pest Management (IPM) include Inspection, Identification, and Monitoring; Prevention utilizing cultural and biological practices; and Control, which strategically uses chemical methods when necessary.
Step-by-step explanation:
The three main components of an effective pest prevention program are often summarized as 1) Inspection, Identification, and Monitoring, 2) Chemical Sprays, Baits, and Traps, 3) Prevention, Education, and Elimination, and 4) Extermination, Fumigation, and Residual Sprays. However, when considering the principles of Integrated Pest Management (IPM), the components might be better framed as combining Inspection, Identification, and Monitoring which emphasize understanding the pest problem thoroughly;
Prevention, which includes using pest-resistant cultivars and cultural practices to deter pests; and
Control, which includes using chemical, biological and cultural approaches as needed while minimizing harm to the environment and human health. The goal of IPM is to manage pest populations below economically damaging levels by using all available pest management techniques including cultural practices, biological controls, and as a last resort, chemical controls.
