Place yellow sticky traps from a hardware store in different areas of a garden. The following results came from one set-up:
The trap near the non-native ornamental plants were full of white fly, the trap near the worm farm mainly had vinegar flies and the two fruit tree traps had lots of fruit flies because there was also an attractant near the sticky trap.
Students were able to use fine forceps to pull off the insects and look at them under a microscope.
Although it was only the insect population in the one garden, they could see the biodiversity (as all the traps had common insects like small moths) and how and why there were different populations in different areas.
They then discussed the predation and also why the sticky traps were used.
