Entomology Final EXAM bby ACTUAL UPDATED QUESTIONS AND CORRECT
ANSWERS
What do Medical and veterinary entomologists do? They study is rarely on insects themselves but rather insect-borne human or
What other types of scientists they work with? animal diseases. The scientists have to have a wide understanding of the vector
insect and also the biology of host and parasite. Lastly, they don't restrict
themselves to just insects and also consider other arthropods. They often work
alongside medical practitioners and researchers, epidemiologists, virologists, and
immunologists.
history of medical-veterinary entomology and what There are Bible verses in Exodus that show negative impacts of insects.
prompted the beginning of modern studies and when Modern Studies of Medical-Veterinary Entomology began in the late 19th century
these began after scientists (like Patrick Mason) discovered that blood-feeding arthropods
were responsible for transmitting diseases.
insect-borne diseases that have had an impact on Yellow fever, Typhoid, Malaria, Trench fever, louse borne typhus, scrub typhus,
American soldiers during wartime leishmaniasis.
, Medical-veterinary entomology interfaces with Medical entomologists: Study of insects, insect-borne diseases, and other
epidemiology and epizootiology associated problems that affect humans and human health.
Veterinary entomologists: Study of insects and insect-related problems that affect
domestic animals, particularly livestock and companion animals but also includes
zoo animals and wildlife.
Epidemiology: Study of the distribution, causes, and risk factors of health related
states or events in specified populations to study the control of health problems.
Epizootiology: Deals with the origin, spread, and decrease of contagious diseases
of animals and methods of preventing and controlling them.
principal insect orders that are of medical-veterinary Blattaria (Cockroaches), Phthiraptera (lice), Hemiptera (True bugs), Coleoptera
interest (Beetles), Siphonaptera (fleas), Diptera (flies), Lepidoptera (Moths and butterflies),
Hymenoptera, Scorpionida (scorpions), Spiders, mites, and ticks.
two types of "damage" that are dealt with in medical- Economic (Veterinary) & Medical/Psychological (Human)
veterinary entomology
Two types of Damage in general: Direct: Immediate effects of an insect bite or sting.
Ex: biting (exsanguination)
Invasion (myiasis)
Toxins, disturbances/ irritations
Indirect: Subsequent effects, not a direct product of a bite or sting. Ex. Allergies,
Phobias, and delusory parasitosis among others.
Maggot Therapy: also known as Maggot Debridement Therapy (MDT). Green blow fly larvae are
kept in colonies to eat dead cells in patients.
Poison: Any substance that when taken into the body interferes with normal physiological
functions (can be injected or ingested)
Toxin: A poison of plant or animal origin which can result in a pathological condition
called toxicosis (illness due to poisoning).
Venom: A poisonous mixture of compounds containing one or more toxins which is
produced in venom glands and injected into animal tissues by stingers.
Cause of disease: The causative agent of diseases may be the insect itself, such as the human body
or head louse, which cause pediculosis, or the mite Sarcoptes scabiei, whose skin-
burrowing activities cause the skin disease scabies.
Vectors of disease: transmitting disease-inducing pathogens from one animal or human host to
another. This transfer may be by mechanical or biological means.
