Chapter 1: Principles Of Pest Management

1.

1. What is the first thing you should do when you detect the presence of a pest?

A.

Select a control tactic
B.

Notify the Department of Agriculture
C.

Identify the organism and gain information about its biology
D.

Determine the economic threshold for control

Correct Answer
C. Identify the organism and gain information about its biology

Explanation
When you detect the presence of a pest, the first thing you should do is to identify the organism and gain information about its biology. This is important because different pests require different control tactics, and understanding their biology can help in determining the most effective control method. It also helps in assessing the potential damage the pest can cause and the economic threshold for control, which is the point at which the cost of control measures is justified by the potential damage caused by the pest.

Suppression of a pest is:

A.

Keeping a pest from becoming a problem.
B.

Reducing pest numbers or damage to an acceptable level.
C.

Destroying an entire pest population.
D.

None of the above

Correct Answer
B. Reducing pest numbers or damage to an acceptable level.

Explanation
Suppression of a pest refers to the act of reducing the population of pests or minimizing the damage caused by them to a level that is considered acceptable. It does not necessarily involve completely destroying the entire pest population. Therefore, the correct answer is "Reducing pest numbers or damage to an acceptable level."

4.

What is a threshold as it relates to IPM?

A.

The level of pesticide required to control a pest.
B.

The levels of pest populations at which you take pest control action to prevent unacceptable damage or injury.
C.

A type of structure designed to be more resistant to pest invasion.
D.

The levels of heat and moisture required for a pest to survive.

Correct Answer
B. The levels of pest populations at which you take pest control action to prevent unacceptable damage or injury.

Explanation
A threshold, as it relates to IPM (Integrated Pest Management), refers to the levels of pest populations at which pest control action should be taken to prevent unacceptable damage or injury. This means that when the pest population reaches a certain threshold, it is necessary to implement control measures in order to avoid significant harm or losses caused by the pests. Monitoring and setting thresholds are important components of IPM strategies to ensure effective and sustainable pest control.

What is pest monitoring? a. Watching your pesticide application kill the pest. b. Recordkeeping of the pesticide used. c. Checking or scouting for pests in an area to determine what pests are present, how many and how much damage they are causing. d. Identifying the pest’s predators.

A.

Watching your pesticide application kill the pest.
B.

Record keeping of the pesticide used.
C.

Checking or scouting for pests in an area to determine what pests are present, how many and how much damage they are causing. Also called 'scouting'.
D.

Identifying the pest’s predators.

Correct Answer
C. Checking or scouting for pests in an area to determine what pests are present, how many and how much damage they are causing. Also called 'scouting'.

Explanation
Pest monitoring, also known as scouting, refers to the practice of checking or scouting for pests in a specific area to determine their presence, population size, and the extent of damage they are causing. It involves actively searching for signs of pests and recording the information gathered. This process helps in understanding the pest dynamics, making informed decisions about pest control measures, and implementing appropriate pest management strategies.

What is integrated pest management (IPM)?. IPM involves...

A.

monitoring, identifying pests, determining threshold levels
B.

Evaluating pest management strategies
C.

Selecting pest management strategies, evaluating the results, and making adjustments
D.

Selecting the most effective pest management strategy that will do the least harm to people, non-target organism and the environment.
E.

All of the above

Correct Answer
E. All of the above

Explanation
Integrated Pest Management (IPM) is a comprehensive approach to pest control that involves multiple steps. These steps include monitoring and identifying pests, determining threshold levels for action, evaluating different pest management strategies, selecting the most effective strategy that minimizes harm to people, non-target organisms, and the environment, and finally, evaluating the results and making necessary adjustments. Therefore, the correct answer is "all of the above" as it encompasses all the steps involved in IPM.

A pesticide was applied, but it did not control the pest. Which of the following is NOT a reason for why the pesticide application might have failed to control the pest.

A.

A pesticide may fail to manage some pests because the pests have developed resistance to the product.
B.

The pesticide was applied in the correct dosage
C.

Pesticide was not properly mixed
D.

Pest was not identified correctly
E.

Pesticide was applied to tops of leaves and the pest is located on the underside of the leaves

Correct Answer
B. The pesticide was applied in the correct dosage

Explanation
The correct answer is that the pesticide was applied in the correct dosage. This means that the amount of pesticide applied was appropriate and should have been effective in controlling the pest. The other options, such as pests developing resistance, improper mixing of the pesticide, incorrect identification of the pest, or applying the pesticide to the wrong part of the plant, could all be reasons for the pesticide application to fail.

Pesticides may lose their effectiveness in a specific area because.......When one pesticide is used repeatedly in the same place against the same pest, the surviving pest population may be more _____________ to the pesticide than the original population was.

Correct Answer
resistant
resistent

Explanation
When pesticides are used repeatedly in the same area against the same pest, the surviving pest population may develop resistance to the pesticide. This means that the pests are less affected by the pesticide and are able to survive its effects. Over time, the repeated use of the same pesticide can lead to the development of a resistant pest population, making the pesticide less effective in controlling the pest.
