Suggested Term Paper Themes
Please choose one and let me know
The term papers will involve original research via published material and internet material. The term paper will include properly done citations within the body of the paper that will match the alphabetized references within the bibliography section at the end. I prefer that you don’t use footnote citations and use the style used in scientific papers.
(1) Based on the biology, physiology and morphology of the order Coleoptera, why has this group been so overwhelmingly successful?
(2) How do insects sense their environment?
(3) Compare and contrast insect control by use of pesticides, biological control, and IPM systems.
(4) Discuss a pest management system for an important defoliator of your choice.
(5) Discuss a pest management system for an important bark beetle of your choice.
(6) Discuss the terrible dangers of introducing forest insect pests from other parts of the world and how would these threats be managed.
(7) Discuss the host selection behavior of the Scolytinae.
(8) Discuss the links between forest fires and forest insects.
(9) Discuss history and pest management strategies to manage either Ips spp. or species of Dendroctonus.
(10) Discuss an important forest pest problem in European forests and how is the problem managed.
(11) Why is the mahogany shoot borer, Hypsipyla spp., such an important tropical pest? .
(12) Discuss the history and future of products derived from the Neem tree.
(13) Discuss the role of genetic engineering in management of insect pests.
(14) Why are MPB outbreaks so huge in the West?
(15) What will be the influence of global warming on insect populations?
(16) Why have MPB populations grown exponentially and are wiping out vast areas of lodgepole pine in the inland West (feel free to consider this a global warming question).
