Mr Posgais Biology II Class Lab



Abstract

Mr. Posgai’s Biology II class often pondered the thought of insects’
attraction to certain colors on flowers. Well, on September 14, 1999, we decided to
experiment and figure out which colors on flowers were more dominant over
others. Our Biology class divided up into groups of two and three people. Each
group took a different colored piece of poster board. One person in each group
applied Tangle Trap to the twelve by nine inch area and stapled each board to a
piece of lattice. We then took the lattice outside, about fifty feet from the school
building and left it outdoors for about forty-eight hours. When we retrieved our
lattice, we counted the number of insects on each board and proved our hypothesis,
that insects prefer yellow flowers and white flowers over the other colors, to be
true.






















Introduction


During the week of September 13, through September 17, Mr. Posgai’s
Biology II class carried out an interesting experiment involving insects and their
color attractions.
Pollination is vital to insect and flower reproduction. Birds and insects drift
from flower to flower, selecting the appropriate “flavor” of their choice to carry on
their necessary task of nature. With the way nature works, this process sounds to be
simple; however, it is much more complicated and in a sense, more unbelievable
than you could ever imagine. A bird or insect flies or walks up into the flower to
reach the pollen. As time moves o, that same bird and/or insect will move on to
something else and carry the pollen with it. The pollen being transferred like this is
a major factor in the flower reproduction system.
My class came up with the hypothesis that the insects would be most
attracted to the colors of yellow and white. Our hypothesis was proved to be true
when we brought in the lattice containing all of the individual colored poster board
pieces. The results were not surprising to us, as white had gathered eighty three
insects and yellow gathering eighty. These colors together almost are more than the
rest of the colors’ insect amount combined.
