Meaning and Definition
A small insect pest that feeds on the roots of corn plants, damaging their growth.
In agriculture, this term refers to any of several aphid species (e.g., Rhopalosiphum rufiabdominale, Anuraphis maidiradicis) that specifically infest the root systems of maize and other cereal crops, often facilitated by ants that farm them for honeydew.
Dialectal Variation
British vs American Usage
Differences
No major differences in referent. However, 'maize' is the preferred scientific and international term, while 'corn' is common in American English; therefore 'maize-root aphid' is an equivalent term used in British/International scientific contexts. The pest is often called the 'rice root aphid' or 'grassy root aphid' in other regions.
Connotations
Neutral technical term in both varieties, implying an agricultural problem.
Frequency
Equally rare in both dialects, limited to specialist discourse.
