Options

A. To reach sexual maturity
B. To attract their own kind
C. To increase body growth
D. To secrete other hormones

Answer

**Step-by-Step Text Solution:**

1. **Definition of Pheromones**: Pheromones are chemical substances produced and released by insects (and other animals) that affect the behavior of other individuals of the same species.

2. **Function of Pheromones**: The primary function of pheromones in insects is to trigger social responses among members of the same species. This means they play a crucial role in communication.

3. **Attracting Mates**: One of the key functions of pheromones is to attract individuals of the same species, particularly for mating purposes. For example, female moths release pheromones to attract male moths.

4. **Examining Options**:
- The first option states "to reach sexual maturity," which is incorrect because pheromones do not influence the maturation process.
- The second option states "to attract their own kind," which is correct as it aligns with the function of pheromones in communication and mating.
- The third option states "to increase body growth," which is also incorrect since pheromones do not have a role in growth.
- The fourth option states "to secrete other hormones," which is incorrect as pheromones are not responsible for hormone secretion.

5. **Conclusion**: Therefore, the correct answer is that the function of pheromones in insects is to attract their own kind.
