1. Maintain cleanliness in rural areas by promptly removing and collecting fallen melons, and treat them through spraying or burial to minimize the breeding ground for pests. This helps in reducing the insect population effectively.
2. Protect flowers by using bags, especially in areas with severe infestations or when dealing with rare plant species. Covering the flowers (when they are just blooming and petals start to wither) can prevent adult insects from laying eggs on them, thus controlling the next generation of pests.
3. Trap and kill adult insects using homemade bait. Mix banana peels, pineapple skins, pumpkin, or sweet potato with 90% trichlorfon crystals in a ratio of 40:0.5:1 to create a paste. Apply this mixture directly onto bamboo frames or hang it inside containers where adult insects are likely to gather. Place 20 traps per 667 square meters, with 25 grams per trap, to maximize effectiveness.
4. Spray insecticides during the adult emergence period. Use 21% emulsifiable concentrate of "killing quail" at noon or evening, or apply 2.5% emulsion at 6,000 times dilution, or 50% dichlorvos emulsion diluted 1,000 times. Repeat the spraying every 3–5 days, and apply it 2–3 times depending on the severity of the infestation.
In addition to these measures, it's important to monitor the fields regularly and keep records of pest activity. This allows for timely intervention and better long-term management. Farmers should also consider rotating crops and practicing integrated pest management (IPM) to reduce dependency on chemical pesticides and promote a healthier environment. By combining these methods, farmers can significantly reduce the impact of pests on their crops while maintaining sustainable agricultural practices.
