To solve the question regarding which component is used as a third generation pesticide, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Types of Pesticides**: - Pesticides are classified into three generations: - **First Generation**: These are inorganic chemicals (e.g., mercury, lead, arsenic) that were initially used to improve crop yield but were harmful and discontinued. - **Second Generation**: These include organic compounds like DDT, which were also harmful and faced restrictions due to their negative effects on the environment and health. 2. **Identify Third Generation Pesticides**: - Third generation pesticides are the most advanced and have the least harmful effects. They are widely accepted in agriculture. - They primarily include **natural substances** such as plant extracts and **insect hormones** (also known as pheromones). 3. **Evaluate the Options Given**: - Option 1: Pathogen - Incorrect, as pathogens are not pesticides. - Option 2: Pheromones - This is a type of insect hormone used in pest management and aligns with the characteristics of third generation pesticides. - Option 3: Insect repellents - Incorrect, as they do not specifically refer to third generation pesticides. - Option 4: Insect hormone analogues - While related, they are not the primary example of third generation pesticides. 4. **Select the Correct Answer**: - Based on the analysis, the correct answer is **Option 2: Pheromones**. ### Final Answer: **Option 2: Pheromones** ---
