Pest
Definition:
(n.) A fatal epidemic disease; a pestilence; specif., the plague.
(n.) Anything which resembles a pest; one who, or that which, is troublesome, noxious, mischievous, or destructive; a nuisance.
Example Sentences:

(2) The main animal paramyxoviruses are parainfluenza 3 (agent of shipping fever) in cattle; NDV (cause of fowl pest) and Yucaipavirus in birds; Sendai and PVM in mice; Nariva virus in rodents; possibly bovinerespiratory syncytial virus; and SV5 and SV41 in monkeys.
(3) Problems that arise when chemical control of pests is applied--risks for producer, applier, consumer and the environment as well as development of resistance against pesticides--have led to the conclusion that other forms of pest control have to be searched for to guarantee production of sufficient crops in the future.
(4) Kairomones may prove useful in manipulating natural or released biological agents for more effective biological control of insect pests.
