Explain why identification of the pest is the first step in developing an effective pest control
strategy. - (ANSWER)Correct identification of a pest allows you to determine basic information
such as life cycle and time that it is most susceptible to pest control. More information leads to
more cost-effective and successful pest control.
Continuous pests - (ANSWER)Nearly always present and require regular control
Sporadic pests - (ANSWER)Migratory, cyclical, or other occasional pests that require control
occasionally or intermittently
Potential pests - (ANSWER)Do not require control under normal conditions, but may require
control in certain circumstances
Host - (ANSWER)A plant or animal on or in which a pest lives
Juvenile hormones - (ANSWER)Natural insect chemicals that keep the earlier stages of an
insect from changing into the normal adult form
,Mycoplasmas - (ANSWER)The smallest knwon living organisms that can reproduce and exist
apart from other living organisms. They obtain their food from plants.
Nematodes - (ANSWER)Small, usually microscopic, eel-like roundworms
Parasite - (ANSWER)An organism living on, in, or with another living organism for the
purpose of obtaining food
Pathogen - (ANSWER)An organism that causes disease in other organisms
Pheromones - (ANSWER)Chemicals emitted by an organism to influence the behavior of other
organisms of the same species
Predator - (ANSWER)An organism that attacks, kills, and feeds on other organisms
Scouting - (ANSWER)Regularly searching for, identifying, and assessing numbers of pests and
the damage they are causing
,Prevention - (ANSWER)Keeping a pest from becoming a problem
Suppression - (ANSWER)Reducing pest numbres or damage to an acceptable level
Eradication - (ANSWER)Destroying an entire pest population
Describe "thresholds" and why they are an important consideration in developing a pest control
strategy. - (ANSWER)The level of pest population at which you should take pest control action
if you want to prevent the pests in an area from causing unacceptable harm. Often set at the level
where the economic losses if the pest populatio grows would be greater than the cost of
controlling the pest.
Thresholds help to make decisions about when to take action to control a pest.
Describe "monitoring" as it relates to pest control and explain why it is important to pest control
strategy. - (ANSWER)The practice of checking or scouting regularly for the presence of pests,
or tracking the population of pests that are continually present. Monitoring shows whether pest
control is working, what types of pests are present, and whether control is needed.
Not needed in situations where pest is continually present and the threshold is zero. Ex: hospital
operating rooms take routine measures to control bacteria.
, Integrated pest management - (ANSWER)The combining of appropriate pest control tactics
into a single plan to reduce pests and their damage to an acceptable level
List several possible control tactics that may be used in an IPM strategy. - (ANSWER)Host
resistance, biological control, cultural control, mechanical control, sanitation, and chemical
control.
Name factors that can cause pesticide applications to fail to control pests. - (ANSWER)Pests
form resistance to pesticides, the pest was not identified correctly, wrong pesticide was used,
pesticide was not applied at the right time, incorrect amount of pesticide was applied, or a new
infestation developed after the chemical was applied.
Name ways to help avoid the development of pest resistance to pesticides. - (ANSWER)Use
pesticides that leave a residue that gradually loses effectiveness over time, rotate pesticides rather
than using the same pesticides for long periods of time
Host resistance - (ANSWER)Use of plants or materials that are naturally resistant to pests. Host
resistance works in three ways:
1. Chemicals in the host repel the pest or prevent it from completing its life cycle.
2. The host is more vigorous or tolerant than other varieties and less likely to be damaged by
pests.
