FRST 352 - Forest Entomology

Hints for Final Exam

Most of this has been stated before, but here it is again ...

• Focus on defoliators, terminal weevils, bark beetles and ambrosia beetles (since theses are the critters we actively manage), of particular interest
  • signs & symptoms - adequate descriptions needed
    • egg gallery ... woefully inadequate
    • egg gallery under bark ... well ... OK
    • vertical egg gallery under bark with larval galleries running sideways at 90 degrees ... good
  • biology - includes overview of life cycle with emphasis on key aspects that allow management
  • damage - describe why we care
  • management
    • often need to differentiate between strategy (a.k.a. what I want to accomplish) vs. tactic (a.k.a. how I'm gonna do it) and/or long term vs. short term
    • relate management options back to the biology of the beast (e.g. can trap for (male) adults in summer because moths use pheromones for 'chemical communication', i.e. 'come and get it')
       
• Other bugs worthy of consideration (a.k.a. Miss Congeniality) include balsam woolly adelgid & plantation/sapling pests
   
• Of course all material is open to be on the exam, but the focus (67+%) will be on the above insect pests
   
• Other ways of 'thinking about' the material ... instead of just re-reading your notes many times, try to
  • draw a line graph that depicts the 'life of a stand of trees' - now indicate what stages are attacked by the various pests we have studied
  • consider a tree genus - pine, true fir, spruce, Douglas-fir, etc. - and note the all critters that attack that tree
• consider the first portion (~1/3) of the course material - it was 'just general entomology' ... when you it read over now ... consider as much as possible how it relates to the significant bugs we have studied
