pest

noun    (Concise Encyclopedia)

Any organism, usually an animal, judged as a threat to humans. Most pests either compete with humans for natural resources or transmit disease to humans, their crops, or their livestock. Invertebrate pests include some protozoans, flatworms, nematodes, mollusks, arachnids, and especially insects. Mammals and birds can also be pests. Human activities, such as monocultural farming practices, use of broad-spectrum pesticides, and introduction of exotic species, often result in the proliferation of pest species. Certain fungi, bacteria, and viruses are also considered pests. Plant pests are usually called weeds.
