QUESTION 1: Which forest insect pest is considered the most
economically destructive to pine stands in Georgia and the
southeastern United States?
• A) Nantucket pine tip moth
• B) Southern pine beetle
• C) Black turpentine beetle
• D) Pales weevil
Correct Answer: B
Rationale: The southern pine beetle (Dendroctonus frontalis) is the
most destructive forest insect pest in Georgia, capable of attacking
healthy and stressed trees, boring through bark, and introducing blue-
stain fungi that disrupt water transport.
QUESTION 2: What is the primary diagnostic sign used to confirm an
active southern pine beetle or bark beetle infestation on a standing
pine tree?
• A) Yellowing needles uniformly spread across the entire crown
• B) Large holes chewed completely through the main trunk center
• C) Resin pitch tubes and reddish-brown boring dust in bark
crevices or at the tree base
• D) Premature cone drop without any other trunk symptoms
Correct Answer: C
,Rationale: Active bark beetle infestations are confirmed by pitch tubes
(masses of resin) and fine reddish-brown boring dust accumulating on
the outer bark or at the base of the tree.
QUESTION 3: How can a forester distinguish damage caused by the
black turpentine beetle from that of the southern pine beetle?
• A) Black turpentine beetles attack only the upper third of the tree
crown.
• B) Black turpentine beetle pitch tubes are typically larger and
located primarily on the lower 6 to 10 feet of the trunk.
• C) Black turpentine beetles do not produce any visible resin or
pitch.
• D) Black turpentine beetles only infest hardwood tree species.
Correct Answer: B
Rationale: Black turpentine beetles tend to attack the lower portion of
the tree trunk (usually the lower 6 feet) and produce larger, reddish-
white pitch tubes compared to the smaller, more numerous southern
pine beetle pitch tubes distributed along the mid-to-upper bole.
QUESTION 4: What is the primary symptom of a Nantucket pine tip
moth infestation in young pine plantations?
• A) Complete defoliation of mature needles in late winter
• B) Death of terminal and lateral shoots resulting in stunted growth
and stem malformation
• C) Deep vertical cracks in the lower heartwood
• D) White cottony masses on the underside of needles
, Correct Answer: B
Rationale: Nantucket pine tip moth larvae bore inside the shoots and
tips of young pines, causing twig dieback, branch distortion, and loss of
height growth in young plantations.
QUESTION 5: Which biological control agent has been widely studied
and introduced to help manage the invasive Hemlock Woolly Adelgid in
eastern forests?
• A) Trichogramma wasp
• B) Laricobius nigrinus (a predatory beetle)
• C) Ladybird beetle variant from local agricultural fields
• D) Entomopathogenic nematode strain native to turfgrass
Correct Answer: B
Rationale: Laricobius nigrinus, a specialized predatory beetle native to
western North America, has been successfully released as a biological
control agent against the hemlock woolly adelgid.
QUESTION 6: What forest disease causes spindle-shaped galls to form
on the stems and branches of loblolly and slash pines, often resulting in
tree mortality or stem breakage?
• A) Annosus root rot
• B) Fusiform rust
• C) Littleleaf disease
• D) Pitch canker
Correct Answer: B
