THE FLYING INSECTS
MENTIONETED SPECIES
Certainly the classification method ( taxonomic criterion, for the academician)
is debatable and at the limit of scientific orthodoxy, but surely practise
even if the species that we will exam, flies and mosquitoes, show a contradiction:
the larval form of this specie doesnt fly but its undeniable
that everybody, also the most tireless entomologist, when he gets wind
of dipterans, thinks about a flying entity.
However this reason wont bring us to neglect technical aspects of
this fundamental kind of struggle.
Moreover its undeniable that the lepidopterans (butterflies) are,
in the adult form, flying bugs and they will treated in the grouping of
the foodstuffs insects. All of this is done in name of the practicality,
with the finality to make "operational" the consultation of
the essay.
THE FLIES
To maintain us faithful to the principle of simplicity we will classify
these bugs gathering them for habitat of election (you see tab. 1).
BIOLOGIC
CYCLE
Eggs
Hatchs time: from 2 to half day in function to the temperature Larval
development (two moulds) : from 20 to 4 days Sfares
time: from 20 to 4 days From the sfare to the mating pass about from 1
to 2 days From the mating to the laying pass on average 3 days ( min.
2 max 9, always in function of the temperature).
The feminine lay the eggs in groups of 100-200 every time (about 1000-2000
eggs in her life).
The biological potential is enormous, but the survivor is on average of
1%.
The number of generations in the space of a year is of 10-15. The wintering
could be in every larval level.
ETHOLOGY
The flies at the adult stage could eat liquid food; They could also liquefy
solid substances ( sugars ) through the salivas regurgitate.
At the larval stage they eat organic substances, overall in fermentation.
In general the adults dont move away from the are where the sfare,
but the migration of ampler breadth are not rear when they take place
with passive transport ( overall on trains and/or planes).
In general you can find the domestic fly in the internal of the structure
in the cold hours, while it moves in the external in warmer hours.

STRUGGLESCHEME
(reference domestic fly)
First of all its necessary well clarify the habitats where its
more important to intervene ( see tab.).
INTERVENTS PROTOCOLS ADULTS
RESIDUAL STRUGGLE
To chose the surfaces to treat and evaluate the extension
To prepare the surfaces ( optional) :
- To dust
- To wash for sprinkler
To prepare with attention the solution/suspension of use
To optional operations add to the solution: sugar, molasses,
milk in reason of 1%.
PLEASE NOTE: Its important to verify the equipments efficiency
prior of the intervention.
Complementary operations (optional) to add to the solution:
sugar, molasses, milk for the 1%.
The aim is to improve in the initial stage the frequentation of
the treated surfaces of flies, overall if you treat partially (in stripes)
or if you employ recall surface like plastic sheets ( in particular when
the intervention takes place in old locals, with crumbling, dirty, absorbent
walls.
Security norms
Take care to follow all the warnings reported in label, with particular
attention to
food and for the presence of people or animals.
Check his/her own outfit: masks, filters, attire
Make the treatment respecting the unity dosages
Wait that the surfaces dry before to reactivate the
place, preferably with a preliminary air.
Objective evaluation of the results.
INGESTION RESIDUAL STRUGGLE
Position with care, in the poisoning points, respecting the indications
in the label.
TRAPS
Viscous adhesive
Food or pheromone attractive
This technique well lend itself to the monitoring.
KNOCK DOWN STRUGGLE
This technique is must to be used only if its impossible to avoid
it: in presence of great infestations, in occasion of epidemic events
in which the flies are an important link of the epidemiologic chain, to
a limited extent to the risk areas of massive frequentation
of the flies (garbages area or dunghills, etc.). You have to scrupulously
respect the dosages favouring the products with a rapid degradation or
with a toxicological outline favourable.

LARVAS
Done save the general indications of the point 1. to have care to well
wet in a way to make to penetrate the liquid in the area of larval reproduction
and follow the calendar of treatments coherent with the management of
the dung and the garbage.
PLEASE NOTE: CERTIFICATE THE TREATMENT ON A APPOSITE FORM, WORK AGEND
OR DIARY, PUNISHMENT THE NULLIFICATION OF THE WORK DONE.
TREATMENT CALENDAR
We have investigated on how to intervene, on where intervene, now we exam
when intervene and we will conclude on why intervene ( even if at this
point is almost obvious).
A concept, never enough deepened, it is that of the necessity to integrate
the various parts of the mosaic so that the everything represents, in
finished way, the whole sketch nothing neglecting: the correct products,
applied in correct way, in the places where the application is necessary
respecting with a suitable calendar of intervention the biological cycle
of the kind target and the relative one to follow him some generations
within the year.
The all, with scrupulous attention in the respects of ours and other people's
safety (you see tab.).
WHY TO INTERVENE? ECONIMIC ASPECTS
Not by chance the term BEELZEBUB (from the Jewish Ba to the zebub = gentleman
of the flies) has assumed in the New Will the meaning of devil. The flies
are a real scourge: their presence is synonymous of dirt and they represent
a human sanitary risk and veterinarian and hygienic industrialist and
non negligible (we will see it in detail in the chart devoted to the illnesses
communicated by the flies) zootechnical.
Besides, their presence constitutes a non negligible factor of depression
of the productivity of any breeding, but also in the tourist context and
of the sport (equestrian particularly) the flies are index of a bad image
and of possible accidents. It must be added that a correct program of
struggle to the flies must have effected with the understanding to reach
concrete results below which it is useless to speak of cost / benefit.
In fact, for the students of the mathematics, but not only for them, if
the benefit extends to zero the ratio tends towards the endless one: in
practical terms money is thrown in interventions that are aimed to create
you an alibi, deprived of economic logic.
THE
MOSQUITOES
With the term mosquitoes, that already in the pronunciation
it remembers the to hum of these annoying bugs, they are suitable numerous
kinds of bugs for the prickliest that the experts call "culicidae."
Its no debatable that the mosquitoes are a great danger for the
men because they are the vector of the malaria, illness that in some part
of the world represent a deadly danger so much to be made to launch appeals
on appeals to the World Health Organization (WHO.) on the dangers of the
contagion above all for the fact that the therapeutic interventions seem
to lose their effectiveness for the resistance that the various
plasmodis go acquiring more and more.
Italy has rooted up this illness in the years as soon as following to
the second world war, but currently doubts rise on the risk of reintroduction
owed to the exotic tourism and the workers in foreign missions in the
areas to risk. Mentioned kind.
IMPORTANT
Numerous cities of the North and Centre Italy they are colonized by the
native kind of the Asian Southeast: Aedes albopictus, note also with the
suggestive name of "mosquito tiger" for the clear rings of its
livery. In the origin areas it is vector of dangerous unlikely pathologies
in our latitudes; an example stays however of the possibility of colonization
of our territories of exotic kind and the necessary attention that should
be set to the problem.
Similar examples of notable course are the to free him of the Corythuca
ciliate, by now a diffused epidemic in all the city trees. Our plane-trees
by now they are of a green chlorate, index of a state of consolidated
suffering.
The rapids American expansion of the Hyfantria in the lowland plain appears
us in its dramatic reality especially in the summer months, where numerous
arboreal and shrubbery kinds show leaf apparatuses devastated by the jaws
of the larvas of this lepidoptera introduced in Europe by the north-American
allied troops.
In the next chapters we will limit there to the urban struggle towards
the group Culex pipiens because it represents more than the 80% of the
problem.
This doesn't owe it stuffed to forget the importance to also identify
also the other kinds from the quantitative point of view and "topographical"
so that the program of struggle is really contemplated, suitable, and
therefore effective.

STRUGLLE
TO THE CITYS MOSQUITOES
BIOLOGIACL CYCLE
From the moment of the laying to the "sfare" of the adult mosquito
they on average spend two weeks. Variability is especially in function
of the temperatures.
This must be reported to the "group" Culex pipiens because in
some kinds of Aedes the egg could remain also quiescent also for few months,
generally the whole autumn and winter period.
In detail we can point out that the egg in the kind of reference (C. pipiens)
opens after two /three days from the laying.
The young larva passes from the stadium L1 to the stadium L4 with three
moults, every phase lasts from two to three days, a further moult brings
our mosquito to the stadium of pupa (mobile) that after forty-eight times
it gives origin to the flying adult which, after some days, it effects
the mating.
Subsequently, the cycle as exemplified it restarts repeating itself within
the year a dozen of times, obviously in relationship to the climatic course.
The adults live some weeks, made exception for the adults that run into
the winter to which the is devolved the duty to survive to the rigors
of the cold season sheltering itself in the basements, in the drainage
system, in the sheltered places, not too much colds.

ETHOLOGY
You remember that the pungent mosquito is the female which must do the
so-called one "blood's meal" to provision him of some amino
acids that it is not able to metabolize and that I am her essential to
complete the maturation of the embryo.
The males are fed of sugary liquids of vegetable origin and they are gathered
in big number, on the occasion of the nuptial flights.
The larvas, instead, eat organic material in suspension in the water,
algae and microorganisms.

STRUGGLESCHEME
(reference to the group Culex pipiens)
Also in this case you have to well identify the habitats where it is more
effective to intervene (you see tab.).

DEMOLISHING STRUGGLE(RESIDUAL)
The technique to be used only in case of reality necessity:
it is generally realized in concomitance of demonstrations and kept parties
to the open one in the warm months; in places of social aggregation; in
places where people eat as fruitshops, restaurants etc.
Atomizers are used to middle, low volume with calibrated dosing, the least
possible.
They adopt products to brief environmental destiny exception done to the
treatments on the spontaneous or even infesting or ornamental vegetation
in which a residual action results of sure great effectiveness.
LARVAL STRUGGLE
Its undoubtedly the technique to be preferred because it strikes
the infesting entity to the origin, a form of preventive intervention.
The results are gotten only if it is possible to intervene on a percentage
of meaningful centre of reproduction. The choice of the products owes
must take into account of the degree of pollution of the water in which
he intends to act.
N.B.THE MOSQUITOS STRUGGLE TAKES PLACE WITH PRECISES CHARTOGRAPHIC
REFERENCES AND WITH CEREFUL, PRECISE AND TIMELYELABORATION OF THE WORK
MAKED

WORKS
CALENDAR
We repeat the key concept in many occasions because even if obvious they
often are disregarded. For instance, the struggle against the wintering
adults often is not realized, like the planning phase and the monitoring
one.
So, after having seen how and where to intervene is well to occupy us
of when to intervene: a careful planning represents one of the fundamental
points to get good results in a logic of economy of exercise (you see
tab.).
WHY TO INTERVENE?ECONOMIC ASPECTS.
The mosquitos struggle is many times carried out because of the
nuisance that these flying syringes cause; it hasnt
be forgotten the sanitary aspect that the puncture of the mosquitos involves.
Beyond the malaria, the mosquito can communicate other morbid forms, also
viral, for the human beings and for the animals: you think about the filariosis
of the dog.
We don't enter the detail in this chapter not to take the risk to emphasize
aspects that the doctors well know and that for the not employed they
can represent a sort of scientific terrorism.
For the economic aspects it is fundamental, when you realize a mosquitos
struggle on territories of a certain extension, to frame such struggle
in a well studied program, better if its formalized in a project,
with techniques of survey and data handling, such to allow the capitalization
of the experiences.
If it is true that the environment is a patrimony common from to safeguard,
and nothing authorizes us to deny it, it is necessary to intervene in
rational way and possibly integrated with everything is done for it. Only
in this way the objectives will be reached in sure and economic way.
