Test 3 Flashcards
Myaisis
Invasion of vertebrates by Diptera larvae. 3 types: accidental, facultative, and Obligatory
Saprophagy
Decomposers. Obtain nutrients by consuming decomposed dead plant material or animal biomass. Sessile consumers.
The weapon of Terrorism
Fear
Forensic Entomology
The use of insects as evidence in law.
Anopholism without malaria
The presence of anopheles mosq, without the disease of malaria. (Still present, still a vector, but no malaria)
Components of Integrated Mosquito management
- Surveillance/capacity
- Source reduction=removal of habitat
- Larvicide/Adulticide
- Prevention of contact
Targets of larvicide
Aquatic homes w/ toxins or oils
Larvae
bio control w/ predators or pathogens
Targets of Adulticide
Adult insects/Arthropods
Attacks transmitters directly. Applies to all vectors-mosq, lice, fleas, ticks, flys. Sprays or ingested.
Source Reductions
Removal or elimination of habitat. “Species Sanitation”
Source reduction Target #1
Fitness-reducing the number of mosquitoes that can be produced
Source reduction Target #2
Vectorial Capacity- ability to transmit by inhibiting pathogen survival or development in the mosquito
Fitness
How much offspring are produced
Ways to prevent contact between host and vectors?
-Clothing
-Window screens
-Repellent (deet/picaridin)
-Bed nets impregnated with incecticide
General approach to lower susceptibility
- Reduce susceptibility
- Eliminate pathogens
- Eliminate reservoir (rats)
Eliminate the vector (part of the triad)
Who talked about spreading smallpox to Native Americans?
Lord
Jeffery Amherst
(1754- During 7 years war)
Negative Effects of Adulticiding?
-Effect on non-target species
-Expensive/Complete coverage difficult
-Toxic
Year to Year Effects of Temperature change on Malaria
-Mosquitoes can breed longer/better fitness
-Better fitness for pathogens
Mosquitoes can travel to locations previously unsuitable (colder)
How are hookworms transmitted?
By soil; where sanitation and hygiene are poor; most often in resource limited countries. (Alabama)
Reportable Disease in NC
Infectious diseases that may be deadly, spread quickly, or become established without quick response. (Malaria, STD, Food borne)
Who is responsible for reporting Reportable Disease?
Physicians
Schools
Medical Facilities
Child cares
Restaurants
Mosquitoes that transmit Zika
Aedes eagypti
And
Aedes albopictus
Types of Mosquitoes in the Family Culicidae
Aedes
Anopheles
Culex
Six degrees of separation
Milgram (1967)
Conducted an experiment proving people on average are six or fewer social connections away from one another
What characterizes emerging pathogens?
Infectious agents recently appeared or increased in a population. Catching health systems off guard.
-outbreaks
-epidemics
-pandemics
