What is the focus of Chapter 14 in Gullan and Cranston?

• A. Insect Predation and Parasitism
• B. Insect Defense
• C. Methods in Entomology
• D. Medical and Veterinary Entomology

Answer: (B)

Defense against predators and parasites is the main focus here, exploring how insects protect themselves and increase their chances of survival. The chapter surveys a wide spectrum of strategies that insects use to avoid being eaten or harmed, from physical and chemical defenses to camouflage, mimicry, and warning signals. It also covers behavioral tactics like playing dead or startling displays, and even social defenses in colony-living species. In addition, it touches on the insect immune responses that fight off pathogens and parasitoids, illustrating defense as a multifaceted toolkit. This is why the right choice fits best: it centers on how insects actively defend themselves, rather than on who predates them, on methods for studying entomology, or on medical and veterinary pest issues.
