Wisconsin's fish food for natural predators
populations sport/recreation

eliminate undesirable fish from rearing ponds
remove exotics
thin stunted fish to bring population back into
5 examples of where fish
balance
control may be
eliminate fish from hatchery when disease controls
warranted
are necessary
treating fish spawning site to avoid overproduction
of a certain species
when some fish are removed it changes the
competition for food and space and can change
why is post treatment
dynamics
management important
use integrated management when possible (tactics
to long-term success
outside of chemicals)
must carefully weigh all risks and benefits
2 main reasons mosquito nuisance and disease concerns
management may be
warranted
eggs
4 stages of mosquito life larvae
cycle pupae
adults
, some have floats, some have spines to catch air and
mosquito eggs
float
4 development stages called "instars"- separated by
molting events
mosquito larvae
3 distinct body regions: head-thorax-abdomen(8
segments with respiratory functions)
comma shaped, transitional, only lasts a few days
mosquito pupae
2 body parts cephalothorax and abdomen
abdomen, 1 pair wings, 3 pairs legs and proboscis,
mosquito adults
distinct head, thorax and abdomen
in order to have an types and locations of breeding sites, #
effective mosquito generations/year, host preference for females,
control program, what seasonal populations and rainfall effects, flight
info do you need to know range, common roosting areas, whether the species
about each species? can transmit pathogens
different species of Aedes vexans, Aedes triseriatus, Culex spp
mosquitos
Aedes vexans most common, inland floodwater mosquito
tree hole mosquito, breed in tires, tins and bird
Aedes Triseraturs
baths
breed in pools high in organic matter, carry WNV
Culex spp
and St Louis encephalitis
la crosse encephalitis - primarily affects children
under 10 years old, can be fatal or cause life long
3 main mosquito neurological difficulties
transmitted diseases WNV- can cause encephalitis in humans, horses and
birds
Dog heart worm
any substance used to directly control pest
populations or reduce pest damage
Pesticide
examples- insecticide, herbicide, piscicide,
fungicide
general characteristics of some directly kill pests, some inhibit growth or
pesticides hormonal function
, organic pesticides contain carbon
inorganic pesticide synthetic, contain no carbon
contains living organism that destroys pest host ie.
microbial pesticide
bacteria or fungus
trade name
different pesticide names common name
chemical name
trade name specific formulation tied to a manufactor
active ingredient- the same among different
common name
producers
same across brands, confusing including letters and
chemical name
symbols
contain phosphorus, most widely used broad
organophosphates
spectrum, non-residual
synthetic versions of pyrethrin, permethrin for
pyrethroids mosquitos for extended residual and work in low
temps
Neonicotinoids nicotine, affects the nervous system
natural origin, highly toxic to humans not widely
botanicals
used
oils suffocate drown or directly kill mosquito larvae
manipulates hormone levels to disrupt normal
insect growth regulators
development
microbial insecticides Bti kills mosquitos specifically
must be absorbed by the plant, must be moved thru
events necessary for a
the plant (if systematic herbicide), must block some
herbicide to kill a plant
important process (photosynthesis)
kill any actively growing plant part they come into
contact herbicides
contact with
a herbicide that is absorbed by the roots and travels
systematic herbicide
throughout the plant
