Scale Insects
🔎 依症狀查找
關於這種疾病
Shell-like insects that attach to stems and leaves and feed by sucking plant sap. Their honeydew secretions can trigger sooty mold, causing both aesthetic damage and plant weakening.
主要症狀
- Brown, white, or gray shell-like bumps may be found fixed to stems and leaves
- Leaves and stems may feel sticky to the touch from honeydew secretions
- A black sooty coating (sooty mold) may appear on leaf surfaces
- Leaves may yellow and fall, and the plant may gradually weaken
主要原因
- Introduction of adults or crawlers on newly purchased plants or soil
- Proliferation in poorly ventilated indoor environments
- Crowded planting with no natural predators present
- Late detection due to infrequent inspection of stems and leaf undersides
預防（栽培環境與日常管理）
Regularly inspect stems and leaf undersides for early detection. Newly purchased plants should be quarantined before placing them near others. Avoid crowding and ensure good airflow around plants.
