CORRECT Answers
CH1 Pest Management - CORRECT ANSWER- ✔✔
Define "Pest" - CORRECT ANSWER- ✔✔A pest is an undesirable organism that injures
humans, desirable plants and animals, manufactured products, or natural substances.
State The Four Main Groups of pests and five an example of each - CORRECT ANSWER-
✔✔Weeds, Invertebrate, Pathogens, & vertebrate animals
Discuss the importance of pest identification in pest control - CORRECT ANSWER-
✔✔Misidentification and lack of accurate information could cause pest control failure.
Accurately identifying pest helps in knowing the best methods of controling them
List six general pest management methods - CORRECT ANSWER- ✔✔Biological Control,
Chemical Control, Cultural Control, Genetic Control, Mechanical/Physical Control,
Regulatory Control
Define "integrated pest management (IPM)" - CORRECT ANSWER- ✔✔A pest
management strategy that utilizes a wide range of pest control methods or tactics. The goal of
this strategy is to prevent pests from reaching economically or aesthetically damaging levels
with the least risk to the environment.
List five benefits of using IPM - CORRECT ANSWER- ✔✔IPM helps to keep a balanced
ecosystem.
Pesticides can be ineffective
IPM can save money
IPM promotes a healthy environment
IPM maintains a good public image
,Discuss how using one or more control options can improve pest control - CORRECT
ANSWER- ✔✔Pests can build up a resistance to pesticides. By using more control options
you can more accurately control the pests.
Describe how selectivity and persistence affect chemical controls - CORRECT ANSWER-
✔✔Selective pesticides can have a great effect on some species and not on others. Persistence
of chemcial pesticides changes with each application. Some can last for years while others
are just short term.
Distinguish between prevention and suppression when developing pest management goals -
CORRECT ANSWER- ✔✔Prevention is planning ahead to stop pest infestations before they
happen and example could be applying pesticide before an infestation happens. Suppression
is reducing the populations of pests after they have infested to area.
Give several reasons why pesticide applications may fail - CORRECT ANSWER-
✔✔Improper pest identifications, An incorrect dosage of pesticide, Application timing not in
accord with pest life cycle. Improper equipment, Poor Environmental conditions like a
rainstorm. improper storage/degradation of old pesticides.
Explain the importance of a pesticide's mode of action in managing pesticide resistance -
CORRECT ANSWER- ✔✔the Mode of action helps reduce the pest developing resistance to
the pesticide.
List two tactics that will minimize the development of pesticide resistance. - CORRECT
ANSWER- ✔✔Changing the pesticide use pattern. Ex. reduce dosage, applying in limited
areas.
Using barriers to prevent pests from getting into an area is an example of which type of pest
management method? - CORRECT ANSWER- ✔✔A.Biological
B. Mechanical
C.Genetic
B
, Making use of plant varieties that are naturally resistant to insect feeding is an example of
which type of pest mangement method? - CORRECT ANSWER- ✔✔A.Biological
B. Genetic
C. Regulatory
B
Which statement about biological control methods is true? - CORRECT ANSWER- ✔✔A.
Modifying the environment to enhance natural enemies is recommended in biological control
B. Biological control involves importing exotic pests to control natural enemies.
C. Using several cultural practices and a wide variety of pesticides works best in biological
control
A
Sealing cracks and crevices and small openings in buildings is an example of which type of
pest management method? - CORRECT ANSWER- ✔✔A. Physical
B.Genetic
C. Biological
A
Which statement about cultural control practices is true? - CORRECT ANSWER- ✔✔A. they
reduce pest establishment, reproduction, and Survival
B. They use naturally derived and/or synthesized chemicals to control pests
C. They involve the release of parasites and predators found in foreign countries.
