Pest
An undesirable organism that injures humans, desirable plants and animals, manufactured
products, or natural substances.
Bioaccumulation
The accumulation of a substance, such as a toxic chemical, in fatty tissues of living organisms.
Biomagnification
The concentration of toxins in an organism as a result of its ingesting other plants or animals in
which the toxins are more widely disbursed.

The four main groups of pests:
1. Weeds (Undesirable plants)
2. Invertebrates (insects, mites, ticks, spiders, snails, and slugs)
3. Disease agents or pathogens (bacteria, viruses, fungi, nematodes [roundworms], mycoplasmas
[parasitic microorganisms], and other microorganisms)
4. vertebrates (birds, reptiles amphibians, fish, and rodents)
pest management methods
Biological Control, Chemical Control, Cultural Control, Genetic Control, Mechanical/Physical
Control, Regulatory Control
biological control
The control of a pest by the introduction of natural enemies such as a predator, parasites,
pathogen, or competitor.

, Wyoming Pesticide Applicator Certification: 2026.
chemical control
Use of chemicals , often called pesticides to manage pests.
Hericide
Chemicals used to control weeds
Mode of Action
The way that a chemical kills or stops growth of pests.
Site of Action
The specific biological system affected within the pest

, Wyoming Pesticide Applicator Certification: 2026.
cultural control
practices that reduce pest establishment, reproduction, dispersal, and survival
Genetic Control
Breeding or selection plants and animals to resist specific pest problems.
Mechanical/ physical control
Control methods specifically taken to kill the pest directly or to indirectly make the environment
unsuitable for pest entry, dispersal, survival or reproduction. Examples include deer fences, cloth
mesh to exclude birds from fruit trees, mechanical vertebrate traps, sticky traps for insects
regulatory control
Quarantine of pests or Eradication (elimination) of Pests.
