Public Health Pest Control Exam
Mosquito Control in Florida in 20th century tourism rocketed after control of salt marsh mosquitoes, prior to this S. penninsular
part of FL = unhabituale, orange county = mosquito county
first organized mosquito effort in FL" WW1 joint effort between US army and US
public health service @ camp johnson near jacksonville, 1919 city of Perry
in the 30s and 40s 1500 miles of drainage ditches dug to drain mosquito breeding
habitats, Burea of malaria Control created wtihin Division of Health, Mosquito
COntroli n Florida, spraying of DDT
how many species of mosquitoes in florida 80+
equipment at a mosquito control district Larviciding: backpack sprayer or hand-operated granular applicator, OR airplane
and helicopter spraying
adulticiding: fogging, spraying, or ULV spraying.. can use
tractors/bulldozing/backhoes for impounding and filling
used of fixed-wing aircraft is the most efficient means to adequately treat large
areas of land
Florida Anti-Mosquito Assisociation formed in 1922, now known as the Florida Mosquito Control Association, FMCA)
mosquito control law chapter 388 florida statues has conditions for mosquito control provisions
what department regulates funding of mosquito control Department of Agriculture and Consumer Services, county/district shall be eligible to
districts, what does current funding act stipulate receive sate funds, the amount of which is described in chapter 5E-13.030
places eggs are laid 1) deposited on water surface
2) deposited on sides of containers wehre water will soon cover them
3) put into damp soil where they mature before they can hatch in water
4) mansonia deposit eggs on the bottom and top of floating aquatic plants
what is special about mansonia and coquiellititia larvae dont take in oxygen from the surface of the water, instead they have a sharp
pointed siphone to poke plants and take oxygen from the plant
pupae "tumbler" stage brief, no feeding, active only if disturbed, emerge into adults by splitting chitinuos
pupal skin into an adult, dry wings
classification of mosquitoes, how many animalia, anthropods, insecta, diptera, culicidae, anopholes, quad
80 species, 12 different genera
anopholes quadrimaculatus - transmits malaria
aedes aegypti - transmits yellow fever and dengue
, Public Health Pest Control Exam
Eastern equine encephalitis alphavirus discovered in massachusetts from infected horses' brains. natural cycle
is between Culiseta melanura and birds, but bridge vectors to humans are
Coquillettidia perturbans, aedes atlanticus, culex nigripalpus, culex
quinquefasciatus, and aedes soliciatans
33% morality, significant brain damage
st louis encephalitis flavivirus discovered in st louis missouri, deaths are mostly in older populations,
case fatality is lower than EEE, not really long term residual neurological damage,
vectored by culex nigripalpus in FL, and culex quinquefasciatus and tasalis in other
parts of the US
West nile encephalitis flavivirus discovered in new york city in 1999 and supposed to be of middle eastern
origin, culex nigripalpus and quinquefasciatus are two major vectors. big mortality in
birds. most eriously affects people 50+, less than 1% have long lasting neurological
effects, 2-5% case fatality rate
breeding seasons most mosquitoes breed mainly in the summer
punctipennis, culex restuans and culex salinarius breed all year round w/ peak
numbers in late spring
arthropod phylum characterized by hard exoskeleton, body is segmented with paired jointed
appendages (ex. insects, mites, cetipedes, spiders)
enzootic present endemically in certain populations
faunal zones list of animal species occurring in a particular region
impoundment coverage of the surface of a marsh with shallow water to prevent exposing
substrate for slat marsh mosquito egg laying because salt marsh mosquitos are
floodwater mosquitoes
integrated mosquito management use of a combination of biological, chemical, educational, and physical control
methods in order to maintain targeted species or populations of mosquitoes at an
acceptable level
ultra low volume a spray application of a pesticide that is a technical or undiluted material and broken
up into very small droplets
arthropods of public health importance eye gnats spread pink eye (conjunctivis), spread of typhoid and intestinal disease
by house flies, food poisioning by cockroaches
TICKS: spread rocky mountain spotted fever, lyme disease, human ehrlichioses and
tularemia
SAND FLIES: genus culicodies only know to be controlled via flooding of breeding
areas, coastal species are more annoying than freshwater
BLIND MOSQUITOES: chironomidae do not feed on blood or vector disease, also
known as midges
how many CEU do you need 16 hours for 4 year license
, Public Health Pest Control Exam
biases of adult traps New jerseys: pros are long-term surveillance in a permanent spot and convienence,
cons are larger organisms and ants which can damage mosquitoes
CDC: pros: mostly mosquitoes and types that do not come to NJ traps, cons: need
to recharge batteries
calibration of ULV machines discharge is in fl. oz/min and is shown on label for insecticides
insecticidal distribution of the ULV machine should be flushed with approx 1 pint of
isopropyl alcohol everytime the unit is used
droplet sizes should be checked every 100 hours of operation and after service
operations
ball type flow meter control system vs positive temperature is a factor...lower temp means lower flow in ball type flow meter control
displacement pumps (ex. variable and constant flow but not in positive displacement pumps
control systems)
calibration of thermal fog equipment you must use a much bigger measuring container than when checking the
calibration of ULV machines, temperature is not an issue because the product is so
diltue
ditching creating ditches or furrows into a salt marsh to provide water circulation and to
make the marsh available to fish
water management legislation for mosquito control districts under chapter 17-4, districts must file applications for permits for water
management activity like dredging and filling, which is submitted to the department
of environmental protection which gos to US army corps of engineers
larvicides three categories of larvicides:
1) contact (ex organophosphate and hormone mimics)
Temephos is relatively low in toxicity, is the only organophosphate registered in
florida, and its mode of action is to inhibit cholinesterase in the nervous systems of
the mosquitoes. honeybee warnings CAUTION and WARNING
Methoprene is a juvenile hormone which prevents pupa from molting into adults, it is
a biochemiccal pesticide, CAUTION
2) surface control agents (ex surface oils/films
Larviciding Oils : coating on top of water that suffocates larvae, pupae, and newly
hatched adults, low toxicity CAUTION
Monomolecular surface films lower surface tension so larvae cannot suspend on top
of water and pupa can not emerge as adults, usually only applied to standing water
3) stomach toxins (microbial larvicides)
BTI - bacillus thuringiensis israelensis are microbial larvicides. active ingredients are
dormanant spore forms of bacteria and an associated toxin. this toxin distrupts the
gut by binding to receptor cells present in insects but not mammals
BS bacillus spaericus is similar, takes longer to work, but is more effective
CAUTION for both, they are both biopesticides, have very minimal effects to outside
environment
