Morphology
The compound 'grape louse' straightforwardly combines 'grape' (the plant/fruit) with 'louse' (a small sap‑sucking insect), so its meaning as an insect pest of grape plants is directly derivable from the constituents. This noun–noun compounding pattern is cross‑linguistically common, so an average B1 learner who knows both words would readily infer the intended meaning even if they do not know the specific species name (phylloxera).
Etymology
Grape louse comes from the simple picture of tiny 'lice' on grape plants: the word louse was used for very small insects that attack plants, and grape shows what they attack. These little pests suck the plant's juices and can damage or kill vines, so the name now means 'a small insect pest that infests and damages grape plants'.
