"tobacco whitefly"的定义和意义

What is a "tobacco whitefly"?

Tobacco whitefly is a small insect belonging to the family Aleyrodidae. It is a common pest that infests a wide range of plants, including tobacco, vegetables, and ornamental plants. The whitefly gets its name from its tiny white wings, which are covered in a powdery wax-like substance. These pests feed on plant sap by piercing the leaves and stems with their mouthparts. In addition to causing direct damage through feeding, tobacco whiteflies also excrete honeydew, a sticky substance that can promote the growth of black sooty mold and attract other pests.
