Why do we have a pest problem?
98% of forests have been logged
Pest populations have been altered by humans

5.2 IPM in Practice
Six Steps of IPM1. Identify your pest and
the damage properly
2. Learn the biology of your pest
3. Survey for pest population

Six Steps of IPM
4. Establish action threshold (tolerance level)
5. Select management tactics
6. Evaluate results

Management Tactics
What you can do about it! Use the IPM Pyramid

IPM Pyramid
First – Use Cultural/Physical Methods Multi-cropping Vacuuming Screens

IPM Pyramid
Second – Biological/Genetic Methods Biocontrol Parasitoids Genetic Engineering

IPM Pyramid
Last Resort! – Chemical Pesticides Round up Insect sprays
