"horn fly" 的定义和意义

What is a "horn fly"?

A horn fly is a small, blood-sucking fly that primarily infests cattle and causes irritation and economic losses to the livestock industry. It has a distinct horn-like projection on its head and feeds on the blood of its host, leading to reduced weight gain, decreased milk production, and potential skin lesions. Control measures are often implemented to manage horn fly populations and minimize their negative impact on cattle health and productivity.
