which covers the surface of the marsh with shallow water and
prevents salt marsh mosquitoes from laying eggs, since they
are laid on damp soil and not on water. - ANSWER-
impoundment
significantly reduced human illness and death, and has greatly
improved human comfort by rapidly and effectively reducing
vector species and pest populations, responsible not only for
creating a healthier environment for human beings, but also for
making it possible to develop and utilize land areas previously
considered unfit for human habitation, larvicides and as
adulticides – ANSWER-Chemical Control
contact larvicides (certain organophosphate and hormone
mimics), surface control agents (surface oils and films), and
stomach toxins (microbial larvicides) - ANSWER-Three
categories of larvicides
organophosphate (OP), only OP registered for use as a
larvicide in Florida, mode of action is to inhibit cholinesterase
in the peripheral and central nervous systems of the larval
mosquitoes, relatively low to moderate acute toxicity, granular
and emulsifiable concentrates, signal word "WARNING" or the
,signal word "CAUTION", use in many habitats including tidal
marshes, woodland
pools, polluted water, tires, and as a pre-hatch
treatment. - ANSWER-
Temephos
juvenile hormone (JH) analog which can be used as a larvicide,
since it can regulate insect growth, inhibits the transformation
of a pupa to the adult insect, biochemical pesticide because
rather than controlling mosquito larvae through direct toxicity,
interferes with an insect's life cycle and prevents it from
reaching maturity or reproducing, signal word "Caution". -
ANSWER-Methoprene
form a coating on the top of the water and drown larvae, pupae,
and emerging adult mosquitoes, one of the most effective tools
for pupal control and can control newly emerged adults that are
resting on the water surface when drying their wings, low
toxicity when used according to the label with minimal
detrimental effects to non-target organisms, "CAUTION" signal.
– ANSWER-Larviciding Oils
utilized as larvicides and pupicides of mosquitoes,
biodegradable and spread spontaneously over the surface of
the water to form an ultra-thin film, mode of action is to lower
the water surface tension, preventing suspension of the larvae
and pupae at the water surface, subsequently suffocating them.
They also interfere with emergence of the adults, pose minimal
risks to the environment and human health, do not last very
,long in the environment, they are usually applied only to
standing water. Typical sites of application include roadside
ditches, woodland pools, or containers which contain few non-
target organisms.
- ANSWER-Monomolecular surface films
microbial larvicide that occur naturally in soils and aquatic
environments globally, active ingredients is delta-endotoxin
crystals produced by various species of bacteria. Mosquito
larvae eat the product that is made up of the dormant spore
form of the bacterium and an associated pure toxin. The toxin
disrupts the gut in the mosquito by binding to receptor cells
present in insects, but not in mammals, control in outdoor
areas such as irrigation ditches, flood water, standing ponds,
woodland pools, pastures, tidal water, fresh or saltwater
marshes, and storm water retention areas, does not pose risks
to wildlife, nontarget species, bear the "CAUTION" signal word
- ANSWER-Bacillus thuringiensis israelensis (Bti)
bacterial larvicide that occurs naturally and is found throughout
the world. mode of action is bacteria are ingested by the
mosquito larvae and the toxin disrupts the gut in the mosquito
by binding to receptor cells present in insects but not in
mammals, much slower acting but their effectiveness is more
persistent, bear the "CAUTION" signal word - ANSWER-Bacillus
sphaericus
organophosphates (OP) and pyrethroids - ANSWER-Two
Classes of Adulticides
, malathion, naled and chlorpyrifos - ANSWER-
organophosphates (OP)
pyrethrum, pyrethrins, permethrin, resmethrin, lambda-
cyhalothrin, cyfluthrin
and D-phenothrin. Etofenprox, a pyrethroid-like
compound - ANSWER-
pyrethroids
organophosphate (OP) insecticide that has been registered for
use in the United States since 1956. Mode of action converted
inside the mosquito into malaoxon, which inhibits an important
central nervous system enzyme called acetylcholinesterase
(AChE). AChE breaks down the neurotransmitter, acetylcholine.
When this enzyme is inhibited by an OP, the neurotransmission
cannot cease and the nerve is over stimulated. Ultimately, this
overstimulation leads to paralysis and death in the mosquito,
applied using both ground and aerial equipment, compound
poses no unacceptable risks to human health or the
environment when applied by label rate - ANSWER-Malathion
OP pesticide that is primarily used for aerial adulticiding in
Florida. Mode of action inhibits an important central nervous
system enzyme called acetylcholinesterase (AChE). AChE
breaks down the neurotransmitter, acetylcholine. When this
enzyme is inhibited by an OP, the neurotransmission cannot
cease and the nerve is over stimulated. Ultimately, this
overstimulation leads to paralysis and death in the mosquito,
