What are the control methods for the black locust seed chalcid?
Methods for controlling the black locust seed chalcid: 1. Strict seed quarantine; it is strictly forbidden to transport seeds carrying the pest elsewhere. 2. Strengthen the management of mother trees; when pests are found, control them with chemical agents. During the adult emergence period, fumigate with 741 dichlorvos tube-inserted smoke agent. Spray with 80% dichlorvos emulsifiable concentrate at 800 to 1000 times dilution, 40% dimethoate emulsifiable concentrate at 1000 to 1500 times dilution, or 20% fenvalerate emulsifiable concentrate at 1500 times dilution. 3. Soaking seeds in hot water (60°C) for 15 minutes can kill the larvae inside the seeds, or use 10% to 20% salt water to select seeds.
