Show Hint
Remember semiochemical categories:
- Allomone: Benefits producer (defense chemicals)
- Kairomone: Benefits receiver (attractants for pests)
- Synomone: Benefits both (mutualistic)
- Allelochemicals: Broad category of all semiochemicals
- Allomone: Benefits producer (defense chemicals)
- Kairomone: Benefits receiver (attractants for pests)

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of chemical interactions between organisms (semiochemicals).
Step 2: Detailed Explanation:
Allomones are chemicals produced by plants (or animals) that benefit the producer by affecting the behavior of another organism (usually a pest).
They are defensive chemicals that protect plants from herbivores and pests.
Examples: alkaloids, terpenoids, phenolics.
Kariomone (Kairomone) benefits the receiver (e.g., a pest), not the producer.
Buprofizin is an insecticide (not naturally secreted by plants).
Allelochemicals are a broader category that includes both allomones and kairomones.
Step 3: Final Answer:
Thus, the correct answer is Allomones, which corresponds to option (D).
