QAL - Plant Agriculture Category Exam
Questions with correct Answers
What ways do non-chemical pest control methods work with an organism's biology? -
Correct Answers -Understanding the life-cycle and natural habitat or predators can aid
in non-chemical pest control by mimicking natural events or minimizing populations by
avoiding creating the perfect timing or environment for pest populations
How does planting transgenic crops affect a pest management plan targeting insects or
mites? - Correct Answers -You may need to apply fewer pesticides; greater number of
nontarget organisms remaining; secondary pests may emerge when primary pest
populations have been reduced; you cannot rely solely on the transgenic crop
How does host plant resistance relate to disease management? - Correct Answers -
must have conventional plants within crop to avoid pest developing resistance or
circumventing around the gene in the plant; "cross protection" similar to vaccinations
How does planting transgenic crops affect a weed management plan? - Correct
Answers -herbicide resistance in crop to be able to spray for weeds throughout crop's
life cycle; ability to switch to conservation tillage; can increase pesticide use and
reliance on single herbicides
How do pest-related transgenic crops fit into an IPM program? - Correct Answers -
transgenic crop targets specific pests; ability to decrease chemical control methods;
scout for secondary pest pressure; diversifies IPM program
What are the relationships among the components of an effective IPM program? -
Correct Answers -they all work together; cannot be reliant on solely one component
What are non-chemical pest management practices? - Correct Answers -biological,
mechanical/physical; cultural - augmentation, tillage, crop rotation
Why is it important to know how living organisms are classified and named? What two
components make up an organism's scientific name? - Correct Answers -For proper
identification and management; confusion across regional boundaries with differing
common names; generic name and specific name
Why is understanding life history and identification of life stages of both pests and crops
is critical? - Correct Answers -for successful control dependent upon pinpointing most
vulnerable life stage of pest and crop; timing
, What ways do pesticides work with an organism's biology and what biological factors
may alter a pesticide's effectiveness? - Correct Answers -some pesticides take
advantage of various characteristics (grooming, metabolism, reproduction, etc.); factors
to consider - life stage, physical strengths and weaknesses, environmental conditions
needed for reproduction, sources of food and shelter
What is the anatomical difference between insects and mites? - Correct Answers -
What are the life stages/life cycle of insects with complete metamorphosis? - Correct
Answers -egg, larva, pupae, adult
What are the life stages/life cycle of insects with incomplete (simple) metamorphosis? -
Correct Answers -egg, nymph, adult
What are the life stages/life cycle of mites? - Correct Answers -egg, larva, nymph, adult
What are the life stages/life cycle of annual, biennial, and perennial weeds? - Correct
Answers -
What are the life stages/life cycle of nematodes? - Correct Answers -egg, larva, adult
What are the life stages/life cycle of vertebrate pests? - Correct Answers -egg, juvenile,
adult
What are the life stages/life cycle of pathogens? - Correct Answers -
What are common sources of insects and mites? - Correct Answers -
What are common sources of inoculum? - Correct Answers -
What are common sources of weeds? - Correct Answers -
What are common sources of nematodes? - Correct Answers -
What types of characteristic damage (symptoms and signs) are caused by insects and
mites? - Correct Answers -
What types of characteristic damage (symptoms and signs) are caused by plant
disease? - Correct Answers -
What types of characteristic damage (symptoms and signs) are caused by weeds? -
Correct Answers -
What types of characteristic damage (symptoms and signs) are caused by abiotic
factors? - Correct Answers -
