What is the focus of Chapter 18 in Gullan and Cranston?

• A. Insect Predation and Parasitism
• B. Insect Defense
• C. Pest Management
• D. Methods in Entomology

Answer: (D)

This question is probing what the chapter title signals about content—the toolkit researchers use to study insects. A chapter titled Methods in Entomology would focus on the procedures and tools of the trade: how to collect insects in the field, preserve and prepare specimens, identify them using morphology and keys, and design and analyze experiments or observations. It’s about the techniques, equipment, and workflows that enable entomological research. This focus differs from topics like insect predation and parasitism, which would explore ecological interactions; insect defense, which covers defensive adaptations and mechanisms; or pest management, which centers on control strategies and applied solutions. Those are thematic subjects rather than a general methods-oriented chapter, making Methods in Entomology the best fit.
