ENT 201 Exam 3 (NCSU) Questions and
Answers (2026/2027) | Updated Review |
A+ Verified
• agent . CORRECT ANSWER: a living organism causing disease in an arthropod-
vectored disease cycles
• augmentation biological control . CORRECT ANSWER: biocontrol reliant on
releasing large numbers of biological control agents to suppress a pest population.
Using biocontrol agents as "living insecticides"
• bacillus thuriengensis . CORRECT ANSWER: soil microbe found virtually
world-wide which produces crystalline proteins toxic to various insects. Widely
used as a microbial insectices, and also a source of genes for transgenic crop plants
• biological control . CORRECT ANSWER: using living organisms to reduce pest
populations
• bubo . CORRECT ANSWER: characteristic; gross swelling of lymph nodes
associated with plague infection
• cattle grub . CORRECT ANSWER: dipteran pests tha develop under the skin of
cattle, damaging leather and causing scar tissue to meat
• chloroquine . CORRECT ANSWER: synthetic anti-malarial drug
• commercial agriculture . CORRECT ANSWER: agriculture in which farmers
produce crop primarily for sale to others
, • conservation biological control . CORRECT ANSWER: controlling pest insects
by protecting the biological control agents already present
• cultural control . CORRECT ANSWER: pest management which relies on
modifying something we would do any way to help reduce pest populations. In
agriculture, could include modifying planting or harvest dates, tillage changes,
crop rotation, etc. In other circumstances, sanitation is an important cultural control
strategy.
• cultural entomology . CORRECT ANSWER: the study of the impact of insects
on human culture and society
• cuticle poison . CORRECT ANSWER: an insecticide which compromises the
integrity of the insect exoskeleton, either through abrasion (dusts), interfering with
epicuticular waxes (soaps), or interfering with the insect's ability to synthesize
chitin. Generally very safe for non-target organisms.
• dengue . CORRECT ANSWER: viral disease transmitted by Aedes mosquitoes.
Also known as breakbone fever
• economic injury level . CORRECT ANSWER: the pest population level at which
the value of the lost crop yield EQUALS the cost of controlling that pest
population
• economic threshold . CORRECT ANSWER: the population level of a pest where
action must be taken to keep the population from exceeding the economic injury
level
• epidemic typhus . CORRECT ANSWER: bacterial disease caused by Rickettsia
and transmitted by the body louse.
