Insects that feed on a single nutritional source are referred to as __________________?
Show answer Hide answer
Answer: A. Monophagous
Explanation
Monophagous insects feed exclusively on a single specific type of food source or host plant. Their digestive physiology and sensory systems are finely tuned to target one specific plant species. Specialized feeding habits make monophagous insects entirely dependent on the survival of their host. Insect feeding habits range from monophagous specialists to polyphagous generalists across species. Monophagy minimizes nutritional competition with other herbivorous insects sharing the same habitat. Evolutionary specialization often binds monophagous insects tightly to specific host plant secondary chemicals.
Monophagous agricultural pests present unique challenges when their host crops suffer widespread failure. Conservation programs must protect specific native plants to ensure the survival of monophagous insects. Entomology studies use monophagous feeding habits to research plant-insect co-evolutionary processes. Polyphagous insects consume a wide range of different plant species across multiple families. Omnivorous insects feed on both plant and animal matter rather than specializing on a single source. Carnivorous insects consume other animal prey exclusively instead of feeding on single plant sources.
