Which characteristic is most useful when distinguishing an insect from a
spider?
A. Presence of wings
B. Number of body segments and legs
C. Ability to reproduce
D. Presence of antennae
Answer: B. Number of body segments and legs
Rationale: Adult insects have three major body regions—head, thorax,
and abdomen—and typically six legs. Spiders are arachnids and have
two major body regions and eight legs. Body structure is therefore a
fundamental characteristic for identification.
Which stage of an insect's life cycle is generally most associated with
feeding damage in chewing insects?
A. Egg
B. Larva or nymph
C. Pupa
D. Adult male only
,Answer: B. Larva or nymph
Rationale: Immature stages such as larvae and nymphs commonly
consume substantial amounts of plant tissue as they develop. However,
the specific damaging stage varies by pest species, so proper
identification of the pest and its life cycle is essential.
What is the primary purpose of scouting a crop before recommending
pest-control measures?
A. To guarantee elimination of every insect
B. To determine pest presence, abundance, distribution, and crop
condition
C. To increase pesticide applications
D. To avoid identifying the pest
Answer: B. To determine pest presence, abundance, distribution, and
crop condition
Rationale: Scouting provides the information needed for an informed
management decision. A PCA should determine whether the pest is
present, how abundant it is, where it occurs, and whether the crop is
actually at risk of economically significant damage.
Which pest-management strategy relies primarily on naturally
occurring predators, parasitoids, or pathogens?
,A. Biological control
B. Mechanical control
C. Cultural control
D. Chemical control
Answer: A. Biological control
Rationale: Biological control uses living organisms or their biological
activity to suppress pests. Examples include predatory insects,
parasitoid wasps, beneficial mites, and microbial pathogens.
What does the term "economic threshold" generally describe?
A. The point at which every pest must be eliminated
B. The pest density at which control action should generally begin to
prevent economic loss
C. The maximum legal pesticide rate
D. The number of pesticides registered for a crop
Answer: B. The pest density at which control action should generally
begin to prevent economic loss
Rationale: The economic threshold is a decision-making concept. It
represents a pest population level at which intervention is warranted to
prevent the pest from reaching the economic injury level.
What is the economic injury level?
, A. The pest density at which economic damage equals the cost of control
B. The minimum pesticide application rate
C. The number of beneficial insects in a field
D. The legal tolerance for pesticide residues
Answer: A. The pest density at which economic damage equals the cost
of control
Rationale: The economic injury level is the lowest pest population that
causes economic damage equal to the cost of management. The
economic threshold is generally set below this level to provide time for
control measures to work.
Why is accurate pest identification critical before selecting a pesticide?
A. All pests respond identically to pesticides
B. Different pests require different management strategies and may
have different susceptibilities
C. Identification is only necessary for recordkeeping
D. Pest identification eliminates the need for scouting
Answer: B. Different pests require different management strategies and
may have different susceptibilities
Rationale: Correct identification determines the pest's biology,
susceptible life stage, likely damage, and appropriate control options.
Treating an incorrectly identified pest can waste money and increase
pesticide exposure without solving the problem.
