\Q\.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
\Q\.how many species of mosquitoes in florida
80+
\Q\.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
\Q\.Florida Anti-Mosquito Assisociation
formed in 1922, now known as the Florida Mosquito Control Association, FMCA)
\Q\.mosquito control law
chapter 388 florida statues has conditions for mosquito control provisions
,\Q\.what department regulates funding of mosquito control districts, what does current
funding act stipulate
Department of Agriculture and Consumer Services, county/district shall be eligible to receive
sate funds, the amount of which is described in chapter 5E-13.030
\Q\.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
\Q\.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
\Q\.pupae "tumbler" stage
brief, no feeding, active only if disturbed, emerge into adults by splitting chitinuos pupal skin
into an adult, dry wings
\Q\.classification of mosquitoes, how many
animalia, anthropods, insecta, diptera, culicidae, anopholes, quad
80 species, 12 different genera
\Q\.anopholes
quadrimaculatus - transmits malaria
\Q\.aedes
aegypti - transmits yellow fever and dengue
\Q\.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
\Q\.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
\Q\.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
\Q\.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
\Q\.arthropod
phylum characterized by hard exoskeleton, body is segmented with paired jointed appendages
(ex. insects, mites, cetipedes, spiders)
enzootic
present endemically in certain populations
\Q\.faunal zones
list of animal species occurring in a particular region
\Q\.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
\Q\.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
\Q\.ultra low volume
a spray application of a pesticide that is a technical or undiluted material and broken up into
very small droplets
\Q\.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
\Q\.how many CEU do you need
16 hours for 4 year license
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 displacement pumps (ex. variable and
constant flow control systems)
temperature is a factor...lower temp means lower flow in ball type flow meter control but not in
positive displacement pumps
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
