- Use fruit fly traps or bait stations to monitor and control adult fruit fly populations in orchards and storage areas.


- Harvest ripe fruits promptly and avoid leaving overripe or damaged fruits on trees, as they attract fruit flies.


2. **Sapota Seed Borer:** Sapota seed borer (Anarsia achrasella) is a moth species whose larvae bore into sapota fruits, causing damage to the seeds and pulp.


- **Precautions:**


- Monitor sapota fruits regularly for signs of sapota seed borer infestations, including entry holes and frass.


- Use pheromone traps or insecticides labeled for sapota seed borer control to manage infestations.


**General Precautions:**


1. **Sanitation:** Keep the orchard clean and free of debris, fallen fruits, and infested plant materials to minimize disease and pest pressure.


2. **Harvesting Practices:** Harvest ripe sapota fruits promptly to minimize the risk of disease and pest infestations during storage and transportation.


3. **Post-Harvest Handling:** Handle harvested fruits with care to avoid bruising or damage that can facilitate disease and pest infestations.


4. **Storage Conditions:** Store harvested fruits in a cool, well-ventilated area with proper airflow to reduce humidity and minimize fungal growth.


By following these precautions during the harvesting stage of sapota fruits, growers can minimize the risk of diseases and pests, ensuring quality fruits for market consumption. Regular monitoring and proper post-harvest management practices are essential for effective disease and pest management during this critical stage.
