Question

Insect use infochemical for intraspecific communication called as:

• A. Kairomones
• B. Pheromones
• C. Secret chemicals
• D. Hydrocarbons

Hint:

- Intraspecific (same species) = Pheromones.
- Interspecific (different species) = Allelochemicals (Allomones, Kairomones, Synomones).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Semiochemicals are message-bearing chemical substances released by plants or animals that elicit physiological or behavioral responses in receiving organisms.
They are broadly divided into intraspecific and interspecific messengers.

Step 2: Detailed Explanation:
- Pheromones are semiochemicals/infochemicals utilized for communication between individuals of the same species (intraspecific communication), such as sex pheromones, aggregation pheromones, or alarm pheromones.
- Allelochemicals (which include Kairomones, Allomones, and Synomones) are utilized for communication between individuals of different species (interspecific communication).

Step 3: Final Answer:
The infochemical used for intraspecific communication is Pheromones, which corresponds to option (B).
