,Question 1
Breeding or selecting plants and animals with characteristics for resistance to pests is an example of which type of pest
management method?
A. Biological control.
B. Mechanical control.
C. Genetic Control.
D. Physical/ environmental modificaiton.
Correct Answer
C
Rationale:
This method involves altering the genetic makeup of a plant or animal to enhance its innate resistance to pests, which directly targets
the organism's genetics rather than an external factor. Therefore, the correct description of this type of pest management is Genetic
Control, as it manipulates the genetic characteristics of the organism to achieve desired outcomes.
Question 2
Using a plow to destry weeeds is an example of which type of mechanical control method?
A. Exclusion.
B. Trapping.
C. Cultivation.
D. Physical/ environmental modification.
Correct Answer
C
Rationale:
Using a plow to destroy weeds is an example of a mechanical control method that physically alters the environment to prevent weed
growth, which aligns with the concept of physical or environmental modification. In this context, the plow is modifying the
environment by breaking up the soil and physically removing or burying the weeds.
Question 3
Which statement is true about chemical control as a pest management method?
A. Pesticides play a key role in pest management programs and sometimes are the only control method available.
B. Pesticides include any material that is applied to plants and the soil but not to water or harvested crops.
C. A highly selective pesticide controls a wide variety of pests.
D. Systemic pesticides are not absorbed by treated plants or animals.
Correct Answer
A
Rationale:
Pesticides are widely used in pest management programs due to their ability to effectively control pest populations, making them a
crucial component in maintaining a balance between agricultural production and environmental health. Option A acknowledges the
significant role of pesticides in these programs, highlighting their importance as a key control method.

, Question 4
Which statement is true about pest management goals?
A. Pestcides are never used to prevent pests.
B. Preventive and suppressive pest control goals are rarely combined.
C. Cultiviation and mowing of weeds are ways to prevent and suppress pest populations.
D. Over large areas, eradication is a practical approach to pest cotnrol.
Correct Answer
C
Rationale:
Cultivation and mowing of weeds can disrupt pest habitats and life cycles, thereby preventing and suppressing pest populations,
making statement C a correct representation of a pest management goal. This approach aligns with integrated pest management
(IPM) strategies that prioritize non-chemical methods to control pest populations.
Question 5
Which term describes the pest population density that causes the losses equal to the cost of control measures?
A. Economic threshold.
B. Economic injury level.
C. Action threshold.
D. Pest threshold.
Correct Answer
B
Rationale:
The term "Economic Injury Level" describes the pest population density that causes losses equal to the cost of control measures, as it
is the point at which the damage caused by the pest equals the cost of the control methods. This concept is key in integrated pest
management (IPM) strategies, where it guides decision-making on when to implement control measures to minimize economic losses.
Question 6
Which would decrease the likelihood of pesticide resistance?
A. Increasing label dosages.
B. Using pesticides from the same class of chemicals.
C. Applying the pesticide over a wide area.
D. Using pesticides with multiple sites of toxicity in an organism.
Correct Answer
D
Rationale:
Using pesticides with multiple sites of toxicity in an organism reduces the likelihood of pesticide resistance because it requires the
target pest to have multiple mutations to survive, making it more difficult for the pest population to adapt and develop resistance. This
approach increases the genetic burden on the pest population, making it less likely to develop widespread resistance to the pesticide.
