Confusion technique uses

Options

A. Juvenile hormone
B. Ecdysone
C. Pheromone
D. A combination of hormones

Answer

### Step-by-Step Solution:

1. **Understanding the Confusion Technique**: The confusion technique is a pest control method that is used by farmers to manage pest populations effectively.

2. **Chemical Release**: In this technique, farmers release a specific chemical into their fields. This chemical is crucial as it plays a significant role in the process.

3. **Pheromone Production**: The released chemical acts as a pheromone. Pheromones are chemical substances produced and released into the environment by animals, particularly insects, to communicate with others of the same species.

4. **Attraction of Male Pests**: The pheromone attracts male pests. This attraction is based on the sexual signals that the pheromone emits, leading the males to believe that a female is nearby.

5. **Confusion of Male Pests**: As the males are attracted to the pheromone, they become confused due to the overwhelming presence of the chemical. This confusion prevents them from locating actual female pests.

6. **Prevention of Reproduction**: Since the male pests cannot find females to mate with, reproduction is hindered. Without mating, there will be no new generation of pests.

7. **Outcome**: The ultimate outcome of this technique is a reduction in the pest population, as the cycle of reproduction is disrupted.

8. **Correct Answer**: Based on this understanding, the correct answer to the question about what the confusion technique uses is **option 3: pheromone**.
