List four pest management strategies described by IPM

• A. Cultural, mechanical, biological, chemical
• B. Pheromone traps, crop rotation, soil tillage, pesticide resistance
• C. Cultural, genetic, mechanical, physical
• D. Biological, chemical, genetic modification, cultural

Answer: (D)

Integrated Pest Management uses four main approaches to control pests: cultural practices, mechanical methods, biological controls, and chemical controls. Cultural practices include things like crop rotation, sanitation, and timing of planting or harvest to disrupt pest life cycles. Mechanical methods involve physical actions or devices such as traps, barriers, or hand removal. Biological controls rely on natural enemies or beneficial organisms to keep pest populations in check. Chemical controls are pesticides used when pest levels threaten damage, ideally chosen and applied in a way that minimizes non-target effects and resistance.

The option that lists these four categories is the correct representation of IPM strategies. Genetic modification is a technology used to develop resistant crops, which can support IPM, but it isn’t one of the four core IPM strategy categories by itself, so it’s not the best fit for this question.
