I. What are the small white worms that weave nets on many roses? These small white worms are actually the larvae of the rose net bug. The rose net bug belongs to the Hemiptera order, Tingidae family, and is a common garden pest. They weave nets on roses, gather together, and cause serious damage to the growth and ornamental value of roses.
II. Characteristics of the damage caused by rose net bugs:
- Wide host range: Rose net bugs not only harm roses but may also harm other Rosaceae plants, such as roses, begonias, etc.
- Parts affected: Rose net bugs primarily affect the leaves of roses, causing symptoms like yellow spots, leaf curling, and leaf drop.
- High reproductive capacity: Rose net bugs reproduce rapidly, with multiple generations occurring in a year, making control difficult.
- Diverse传播 routes: Rose net bugs can be spread through wind, rain, or human transport, easily causing large-scale damage.
III. How to rectify the situation?
- Eliminate the pest source: When rose net bug damage is detected, promptly remove the affected leaves and burn or bury them to reduce the pest source.
- Biological control: Use natural enemies like ladybugs and green lacewings to control the rose net bugs. Planting some plants that repel insects, like mint and lavender, in the garden can also be effective.
- Chemical control: In severe cases, high-efficiency and low-toxicity insecticides can be used for spray control. Common insecticides include pymetrozine, thiamethoxam, and lambda-cyhalothrin. Be sure to rotate insecticides to avoid resistance.
- Strengthening maintenance management: Enhance the plant's disease resistance, keep the soil moist, prune appropriately for good ventilation and light exposure. Also, apply fully decomposed organic fertilizers and avoid excessive nitrogen fertilizers to prevent plant overgrowth.
- Preventive measures: Regularly inspect leaves during rose growth and deal with damage promptly. During the winter, prune plants, removing weak and diseased branches to reduce overwintering pests.
IV. Summary: The small white worms that weave nets on roses are the larvae of the rose net bug. In the face of this threat, we must adopt comprehensive control measures, including eliminating the pest source, biological control, chemical control, strengthening maintenance management, and taking preventive measures to ensure the normal growth and beauty of roses.
