According to a recent survey conducted by the Beijing Plant Protection Station, the local plot of rapeseed in the suburbs of the Beijing suburbs is severely damaged. Some newly emerged seedlings have been eaten, resulting in lack of seedlings and ridges; the larger seedlings have been damaged. Many holes.
After verification, the pest is a yellow-flesh hop, which is commonly known as a fleas and ground lice. Adults are dark brown, long, oval-shaped beetles, each with a yellow longitudinal spot on the elytra. The spring and autumn seasons are heavy throughout the year, and autumn is obviously more important than spring; high humidity is more important than low humidity fields.
At present, the main prevention and control measures that can be taken include: removing defoliation and weeds from the vegetable field in winter to eliminate overwintering sites; using black light or yellow armyworm board to trap and kill adult insects; use thiamethoxam and other agents for seed dressing before sowing; larval period can be Use 40% phoxim EC 1000 times solution, 40.7% Le Siben EC 1500 times solution and apply 150-250ml/plant. Adult insects can use cypermethrin, deltamethrin, diflubenzuron and other agents spray.
1000Hz High Frequency LiDAR System
