Hypothesis
Do RTB's use kairomones to discriminate between large and small host trees?
Conclusion
The study found that the red turpentine beetle prefers to attack large-diameter trees due to the higher concentration of beneficial compounds in their bark.
Supporting Evidence
- RTBs preferred the bark of large-DBH trees over small-DBH trees in behavioral assays.
- Both large- and small-DBH trees had the same composition of monoterpenes, but the concentration differed.
- Large-DBH trees provided more nutrients and better habitat for RTBs.
Takeaway
Bark beetles like to eat from big trees because they have more food and space for their babies.
Methodology
The study involved laboratory experiments where the attacking behavior of red turpentine beetles was observed on large and small-diameter trees.
