Final Examination, Entomology 10, Winter Quarter 2008 Name_________________________________ 1A. Scantron Questions 1-15. Fill in the correct “bubble” for the following questions. “A” for True and “B” for false. Each question is worth 2 points. Total points = 30. 1.True /False. Rachel Carson’s book, “Silent Spring”, was a major factor in the Environmental Protection Agency’s decision to ban DDT use in the U.S.A. in the early 1970s. 2.True/False. A disadvantage of using biological control is that even though an insect pest is attacked by a parasitoid, the pest continues to feed until it is finally killed by the parasitoid. 3.True/False. Chemical insecticides such as organophosphates are more compatible with natural enemies (parasitoids and predators) because they tend to exhibit broad-spectrum activity and rapid mortality. 4.True/False. An example of the Red Queen hypothesis is when researchers run hard to try to keep ahead of a parasitic organism but the parasitic organism becomes resistant to the control agent. 5.True/False. Sex pheromone traps are effectively used to monitor and/or detect some insect pest densities, especially for male moths. 6.True/False. Malaria is a good example of zoonosis, a disease in which the parasite has humans as a reservoir and mosquitoes as the vectors. 7.True /False. Insects that are scavengers (i.e., necrophages) are good forensic tools because they have discrete life stages and their development rates are linked to temperature. 8.True/False. Heat generated by maggot masses has little or no impact on fly development rates and is not a concern for forensic determinations of post mortem intervals. 9.True/False. For human consumption, insects are readily available and easy to collect, but are not good sources of protein and fat. 10.True/False. Bubonic plague is present in California in the Sierras and rodents (chipmunks, squirrels and rats) serve as reservoirs of the pathogen. 11.True/False. The EPT (Ephemeroptera (mayflies), Plecoptera (stoneflies), Trichoptera (caddis flies) index is useful to indicate the health of a stream. 12.True/False. Paul Müller, a chemist, invented the organophosphate insecticide known as parathion, and received the Nobel Prize in Medicine for his discovery because this insecticide was a major factor in reducing malaria and typhus during World War I. 13.True/False. The worm (caterpillar) in Mezcal is an indication that the product meets the standard for alcohol content. 14.True/False. Monarch butterfly larvae are killed in high numbers by eating Bt corn pollen that contaminates the milkweed plant. 15.True/False. Genetically modified organisms or GMOs include plants and animals improved by traditional breeding.
