What is a severe pest? - (ANSWER)A pest present in populations that are always
above the economic injury level in the absence of control.
What is an occasional or secondary pest? - (ANSWER)A pest that can cause
damage above economic injury levels only at certain times.
What is a potential pest? - (ANSWER)A pest that typically causes no apparent
economic damage under normal circumstances.
What is a migratory pest? - (ANSWER)A pest that may cause serious economic
damage on a periodic basis.
What are the five steps of developing an IPM program? - (ANSWER)1. Identify the
pest to be managed.
2. Define the management system.
3. Develop the pest management strategy.
4. Develop reliable monitoring techniques.
5. Use economic thresholds.
What is an economic threshold? - (ANSWER)The level or density of a pest
population where control measures need to be applied to prevent the pest from
reaching the economic injury level.

What is an economic injury level? - (ANSWER)The pest population density that
causes losses equal to the cost of the control measures.
What are mechanical control methods? - (ANSWER)Devices that prevent the
spread or reduce the infestation of pests, primarily insects and vertebrate
animals. Mechanical controls include hand destruction, traps, and mechanical
exclusions such as screens, nets, and fences.
What are physical control methods? - (ANSWER)The manipulation of water,
humidity, temperature, electric shock, or other radiant energy to kill, alter the
pests life cycle, or create an unfavorable environment for the pest to live in.
What are cultural control methods? - (ANSWER)The manipulation of the
environment to avert serious pest damage. Cultural control methods require
knowledge of the plants needs and potential problems. Ex: irrigation
management, rotating crops, pruning, cover crops, etc.
What are generic control methods? - (ANSWER)The use of plants and animals
that are resistant to attack by pests. Ex: Traditional breeding techniques
combined with genetic manipulation of plants to promote host plant resistance to
pests and disease.
What are biological control methods? - (ANSWER)Involve the introduction,
encouragement, and/or artificial increase of plants and insects/animals that are
parasites or predators of a pest species.

What are chemical control methods? - (ANSWER)Involve the use of naturally or
synthetically derived chemicals that, kill, attract, repel, or otherwise manage the
growth of a pest.
Avicides - (ANSWER)Management of birds.
Bactericides - (ANSWER)Management of bacteria.
Fungicides - (ANSWER)Management of fungi.
Herbicides - (ANSWER)Management of plants.
Insecticides - (ANSWER)Management of insects and insect relatives.
Miticides - (ANSWER)Management of mites.
Molluscicides - (ANSWER)Management of snails and slugs.
Nematicides - (ANSWER)Management of nematodes.
Piscicides - (ANSWER)Management of pest fish.
