Definition of coccid in English:
A homopteran insect of the family Coccidae; a scale insect.
- The tiny adult males are winged but the female coccids remain in the galls all their lives.
- Aphids and coccids are major pests of agriculture and forestry throughout the world.
- The only downside is the vigour of the tree, which is weakened by the sap sucking of the coccids.
