  1. Abstract
  2. Mr. Posgai’s Biology II class often pondered the thought of insects’
  3. attraction to certain colors on flowers. Well, on September 14, 1999, we decided to
  4. experiment and figure out which colors on flowers were more dominant over
  5. others. Our Biology class divided up into groups of two and three people. Each
  6. group took a different colored piece of poster board. One person in each group
  7. applied Tangle Trap to the twelve by nine inch area and stapled each board to a
  8. piece of lattice. We then took the lattice outside, about fifty feet from the school
  9. building and left it outdoors for about forty-eight hours. When we retrieved our
  10. lattice, we counted the number of insects on each board and proved our hypothesis,
  11. that insects prefer yellow flowers and white flowers over the other colors, to be
  12. true.
  13. Introduction
  14. During the week of September 13, through September 17, Mr. Posgai’s
  15. Biology II class carried out an interesting experiment involving insects and their
  16. color attractions.
  17. Pollination is vital to insect and flower reproduction. Birds and insects drift
  18. from flower to flower, selecting the appropriate “flavor” of their choice to carry on
  19. their necessary task of nature. With the way nature works, this process sounds to be
  20. simple; however, it is much more complicated and in a sense, more unbelievable
  21. than you could ever imagine. A bird or insect flies or walks up into the flower to
  22. reach the pollen. As time moves o, that same bird and/or insect will move on to
  23. something else and carry the pollen with it. The pollen being transferred like this is
  24. a major factor in the flower reproduction system.
  25. My class came up with the hypothesis that the insects would be most
  26. attracted to the colors of yellow and white. Our hypothesis was proved to be true
  27. when we brought in the lattice containing all of the individual colored poster board
  28. pieces. The results were not surprising to us, as white had gathered eighty three
  29. insects and yellow gathering eighty. These colors together almost are more than the
  30. rest of the colors’ insect amount combined.
  31. Materials and Methods
  32. -9 Different color poster boards:
  33. red, blue, yellow, white, purple, green, black, orange, and hot pink
  34. -Tangle Trap
  35. -Putty knife
  36. -Pencil
  37. -Ruler
  38. -Lattice
  39. -2 sticks
  40. Everyone in the class first divided up into groups of three and four people.
  41. Each group chose a 14” by 11” piece of poster board of a different color. They
  42. took the ruler and marked off with the pencil, approximately a one inch border for
  43. handling. With the putty knife at hand, they applied the Tangle Trap to the middle
  44. of the board, being careful not to let it get on their hands or clothing. Handling the
  45. piece of poster board by the one inch border on the sides, each group carefully took
  46. their board and stapled it to the lattice. The lattice was then placed outside (being
  47. held up by the two sticks) with all nine different colored poster boards stapled on
  48. it, with each piece having a 12” by 9” available trapping space. After about
  49. forty-eight hours, they retrieved the lattice and each group took back their assigned
  50. color and counted the number of insects on it.
  51. Discussion/Conclusion
  52. After retrieving our lattice board from outside, and carefully counting over
  53. and over, for reassurance, the total amount of insects on each piece of poster board,
  54. and the different types, our class came to the final conclusion that yellow, white,
  55. and red were the more dominant colors in this particular experiment. Although, this
  56. did not exactly match our hypothesis, the results were close.
  57. Also, you must take in to consideration when reading this conclusion that we
  58. only made one trial. During a normal experiment, there should be more than one
  59. test. Afterall, if is hard to determine the facts of nature with multiple experiments,
  60. let alone just one.
  61. There could also be many other factors which affected our results. An
  62. example would be that not everyone calculated exactly a one inch border from the
  63. sides of their poster board. Some people may have put the Tangle Trap on their
  64. board thicker than others, which would lead to more or less insects sticking to their
  65. particular poster board. Another factor may be that the group who was in charge of
  66. the purple poster board had to color a plain white piece. Meaning that the board
  67. may not be completely purple, and the insects may be attracted to the white spots
  68. showing through the colored board.
