turnip moth
C2Technical/Agricultural
Definition
Meaning
A nocturnal moth (Agrotis segetum) whose larvae are agricultural pests, damaging root vegetables and other crops.
A specific species of cutworm moth known for its destructive impact on young plants, particularly root crops like turnips, hence its common name.
Linguistics
Semantic Notes
The term is a compound noun referring specifically to one species. The name directly references its larval host preference (turnip) and its insect order (moth). It is a concrete, countable noun but often used in a collective sense when discussing infestations.
Dialectal Variation
British vs American Usage
Differences
The term is used in both varieties, but more commonly in UK/European agricultural contexts where the pest is prevalent. In North America, similar damage is often attributed to other 'cutworm' species, making the specific term 'turnip moth' less frequent.
Connotations
Purely technical/agricultural; connotes crop damage and pest management.
Frequency
Higher frequency in UK agricultural texts and EU pest advisories. Very low frequency in general American English.

FAQ
Frequently Asked Questions
No. While named for its association with turnips, its larvae (cutworms) are polyphagous and attack many root vegetables, cereals, and other young plants.
The specific species Agrotis segetum is primarily Eurasian and African. Similar damage in the US is typically caused by native cutworm species, not the 'turnip moth' as defined here.
It is a two-word compound noun, written as two separate words. It is not hyphenated in standard usage.
Control focuses on the larval stage (cutworms). Methods include using protective collars around seedlings, promoting natural predators, and, if necessary, applying biological or approved chemical controls at the right time in the pest's lifecycle.
