  1. Natural Insect Control By Elaine, James, and Josh Environmental Biotechnology

  2. Outline of Proposal • Problem Identification • Project Objective • Rationale for Project • Methods: materials, procedures, data analysis

  3. Problem We Identified • Many pests like mosquitoes and flies • Especially in spring, summer, and fall • Swampy environment behind school • Mosquitoes proliferate • We always get bitten on field day!

  4. Problem Cont. • School uses pesticides to control pests. • Can have adverse effects: • May kill plants and beneficial insects • May harm people • Pesticide-resistant pests

  5. Project Objective • To lessen the amount of pesticide our school uses by planting pitcher plants (Serracenia rubra) while being able to control pest proliferation.

  6. Pitcher Plants • Serracenia rubra • Perennials • Requires winter dormancy and tolerates warmer temperatures • 10-20 degrees F tolerance • 6hrs sunlight • Pitfall traps (tubular funnels) • Carnivorous plants • Secretes nectar to attract and reduce dilution • deep folds into slippery pools filled with digestive enzymes

  7. Danger To Humans • Tehran • Analyzed pesticide related death • Pesticide Poisoning • 1.31% of deaths • 50% of those were suicide • Concluded safer way needed • (Soltaninejad 2007)

  8. Further Risks • Inhibition of G6PD • Needed for Metabolism • Arrive by land, sea and air • Deltamethrin (common) • Highly Effective • (Şentük 2009)

  9. Danger to Pitcher Plant • Analyzed Evolution • Difficulties due to low pop. • Over Collection • Lack Land • Conserve • Able to survive stressful environment • (Ellison 2001)

  10. Lasting Effect • Pitcher plants perennials • Used to 10% Nitro from Insects • >10%, more growth • (Ellison 2001)

  11. Materials • Pitcher Plants (15- they will reproduce)* • Must be ordered- about $6 a plant • 2 Standard Soil Mix Bags- 50% peat moss, 50% pear lite* ($3 for 1 gallon bag) • Water and Watering Can- for first day • Gardening Tools • Rake, hoe, shovels, spades • Tabletop Balance and Weigh Boats • Gloves (both rubber and gardening) • Forceps

  12. Procedure • Will locate regions for planting the pitcher plants in the back of the school • Close to brook/creek/swampy area

  13. Picture

  14. Procedure Cont. • Will clear area of grass and leaves in designated regions. • With gardening tools, will dig a 1-2ft ditch/hole in planting areas. • Will gently remove plant from pot/packaging and place in ditch. • 3 plants per designated region • Will place soil around plants to hold them down

  15. Procedure Cont. • Once every week, will vertically cut from the opening to the petiole. • Only for one of the plant’s traps • One per designated area • Will count number of dead insects (exoskeletons are not digested and are identifiable) • Will take mass of collected exoskeletons

  16. Picture Bank

  17. Procedure Cont. • After monitoring for 3 weeks, we will increase the number of pitcher plants in the area where the most exoskeleton were seen. • Will continue collecting exoskeletons for 3 more weeks.

  18. Data Analysis • Will collect the number of exoskeletons over 6wks (after we add more plants) • Average and standard deviation over 6wks per area • Check for variety of data • T-test between all the regions against each other

  19. Conclusion • Pitcher plants will be an effective method for reducing the amount of pesticides used by significantly reducing the number of pests. • Small step to a brighter and greener future!
