TOPIC 1: PEST MANAGEMENT METHODS
6 Questions • 6.7% of Exam • Covers various pest control methods, including mechanical and genetic controls.
QUESTION 1
Using barriers to prevent pests from getting into an area is an example of which types
of pest management method?
Correct Answer: Mechanical control.
Rationale: Using barriers to prevent pests from getting into an area involves manipulating or controlling the physical
environment to exclude pests, which is a key characteristic of mechanical control. Mechanical control refers to the use of
non-chemical methods, such as physical barriers or traps, to manage pest populations, making barriers a prime example of
this type of approach.
QUESTION 2
Sealing cracks and crevices and small openings in buildings is an example of what type
of mechanical control method?
Correct Answer: Exclusion.
Rationale: Sealing cracks and crevices and small openings in buildings prevents pests or rodents from entering the
structure, which is a form of exclusion control. Exclusion control methods focus on preventing the entry of unwanted
organisms, rather than removing them once they are inside, making it the correct classification for this type of mechanical
control method.
QUESTION 3
What is the purpose of the fit check when using a respirator?
Correct Answer: To make sure you have a tight-fitting seal with no leakages each time you use the respirator.
Rationale: The purpose of the fit check is to ensure the respirator is properly sealed to the user's face, preventing unfiltered
air from entering the mask and compromising its effectiveness in protecting against airborne contaminants. A tight-fitting
seal is crucial for the respirator to function correctly, and a fit check helps identify potential gaps or leakages that could
compromise the user's safety.

QUESTION 4
Breeding or selecting plants and animals with characteristics for resistance to pests is
an example of what type of pest management method?
Correct Answer: Genetic control o.
Rationale: Breeding or selecting plants and animals with characteristics for resistance to pests is an example of genetic
control because it involves manipulating an organism's genetic makeup to prevent pest infestation, thereby reducing the
need for external pest control methods.
This approach targets the pest's vulnerability to specific plant or animal traits, making genetic control a proactive and
sustainable pest management strategy.
QUESTION 5
Using a plow to destroy weeds is an example of which type of mechanical control
method?
Correct Answer: Cultivation.
Rationale: Using a plow to destroy weeds is an example of cultivation because it involves physically removing or uprooting
weeds from the soil through mechanical means, which is a key characteristic of the cultivation method. Cultivation focuses
on physically disrupting or removing unwanted plants, making it the most relevant mechanical control method in this
scenario.
QUESTION 6
What term describes the pest population density that causes losses equal to the cost of
control measures?
Correct Answer: Economy injury lecel.
Rationale: "Economy injury level" is the correct term because it specifically refers to the pest population density at which the
economic losses caused by the pest equal the cost of implementing control measures, serving as a threshold for
determining the need for control. By defining this level, it allows farmers and pest managers to make informed decisions
about when the cost of control measures outweighs the potential economic benefits of inaction.
