What is a severe pest? 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? A pest that can cause damage above economic injury levels
only at certain times.
What is a potential pest? A pest that typically causes no apparent economic damage
under normal circumstances.
What is a migratory pest? A pest that may cause serious economic damage on a
periodic basis.
What are the five steps of developing an 1. Identify the pest to be managed.
IPM program? 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? 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? The pest population density that causes losses equal to the
cost of the control measures.
What are mechanical control methods? 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? 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? 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? 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? 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? Involve the use of naturally or synthetically derived chemicals
that, kill, attract, repel, or otherwise manage the growth of a
pest.
Avicides Management of birds.
Bactericides Management of bacteria.
Fungicides Management of fungi.
Herbicides Management of plants.
Insecticides Management of insects and insect relatives.
Miticides Management of mites.
Molluscicides Management of snails and slugs.
Nematicides Management of nematodes.
