Insect pest in agriculture
A pest is "a plant or animal detrimental to humans or human concerns (as agriculture or livestock production)";[1] alternative meanings include organisms that cause nuisance and epidemic disease associated with high mortality (specifically: plague). In its broadest sense, a pest is a competitor of humanity.[2] In the past, the term might have been used for detrimental animals only, thus for example, causing confusion where the generic term "pesticide" meant "insecticide" to some people.
