3. What did students learn (L) about the topic?
Students learned that the beetles seemed to prefer the lighter colored roses. Students
also learned that this may be due to differences in odor rather than being based solely
on color.
Hypothesis:
If given a choice between yellow roses and red roses, Japanese beetles will choose the yellow
roses.
Procedure:
1. Place one of each rose cutting in each of the 6 containers (6 yellow, 6 red).
2. Cuttings should be placed in container so the blooms are facing opposite ends like
the diagram below.
Red Yellow
3. Place one Japanese beetle in each of 6 containers.
4. Place the lids on each of the 6 containers to prevent the beetles from escaping.
5. Collect and record data for beetle location at given time intervals for each of the
SIX REPLICATIONS.
Questions for Further Study
• Do Japanese beetles behave differently when they are in groups or alone?
• Do Japanese beetle flower preferences relate to odor more than color?
• Do male and female Japanese Beetles prefer the same flowers?
