IPA: /ˈbɔlˌwɜrm/
KK: /bɔlˌwɜrm/
A type of moth whose larvae feed on cotton plants, causing damage to the crops.
Farmers often struggle with bollworm infestations in their cotton fields.
Bollworm → The word is formed from 'boll' (from Middle English *bolle*, meaning a seed pod or capsule) and 'worm' (from Old English *wyrm*, meaning a serpent or worm). A bollworm is a type of caterpillar that infests the seed pods of plants, hence the combination of these parts describes a worm that lives in seed pods.
Think of a 'seed pod' ('boll') being infested by a 'worm' — that's why a bollworm is a caterpillar that lives in seed pods.
