Morphology

onion + louse

The meaning 'a small insect harmful to onion plants' is directly and transparently derived from combining 'onion' (the vegetable) with 'louse' (a small sap-sucking insect), i.e. a louse associated with onions. This literal, compound naming pattern for pests is common and cross-linguistically regular, so a B1 learner who knows both constituents would readily infer the meaning.

Etymology

Onion louse comes from the simple image of a small louse living on an onion plant and feeding on it. That's why the name means 'a tiny pest that damages onion plants and sometimes tobacco'.
