STRUGGLING
PLANS
Actually
the struggling plans imitate the Integrated Pest Management (IPM)s strategies
that will be subsequently detailed and they must integrate with the Hazard Analysis
and Critical Control Point (HACCP) therefore the overtaking of the critical
points of the process subject to our work.
This premised we analysed the various kind of struggle with a logic of enunciation
almost didactic; the object is define the limits and the characteristics.
TARGETED STRUGGLE
You defines in this way the intervention useful to eliminate or reduce making
not harmful, only the organism target, acting in a not indiscriminate way, but,
as the word remembers, contemplated.
The selectivity of such application methodology is realized through various
techniques, for example with a distribution of products limitedly to the places
frequented by the parasites target.
Or the interventions are realized in that moments in which the parasites are
present in maximum concentration while the "not target" are not there
or they are present in least part.
Or you can used technical resources enable to allow only to infesting entity
the contact with the biocide, a classic example is the bait-box (safety supplying
for the rat-killing bait) for rodents.
Naturally the use of pheromones traps or of products that interfere with
the moults (the I.G.R. = Insect Growth Regulator) are the means at higher intrinsic
selectivity. In this chapter is due mention the so-called biological insecticide,
deriving from the almost totally of the Bacillus Thuringiensis. It precisely
consist in endotoxins product by the bacillus. These act with a good selectivity
cause diseases that bring to death the defoliating lepidoptaras (B. thuringiensis
varietà thuringiensis) and the mosquitoes at the larval level
(B.thuringiensis varietà israelensis).
BIOLOGICAL STRUGGLE
Its overall known in the agricultural sector from a century, its
the ecologists bulwark.
It uses every method, excluding the chemicals ones, turn to directly eliminate
the infesting entity. The methods that employ the predators or the specific
parassitoids and that use traps.
These methods dont want to totally eliminate the infesting agent, thing
very difficult and improbable, but they want to reduce it to a acceptable
presence, both in hygienic and economic terms. At this aim you define a threshold
of damage and you act a continuous monitoring turn to point out the moment of
intervention more suitable in relation to the biological means to disposition.
The potential advantages on the territory are evident; in this case the limits
are scarce or nothing effectiveness, but emerge also the not applicability of
the method in the sanitary context or in the food industry where the presence
of every insects are not bore.
INTEGRATED OR GUIDED STRUGGLE
Like for the biological struggle, it foresees the determination of a damage
threshold ( or of intervention) and it includes between the practices also the
use of chemical products for the employment only when the choice is necessary
and the manner very prudent, favouring the more selective formulations and those
ones that present the toxicologist outlines more favourable.
The actual proclivity is aimed to this kind of struggle, both in agricultural
sector and in civil sector with the progressive abandon traditionally and surpass
generalized or indiscriminate struggle. For the integrated struggle also are
necessary continue monitoring aimed to take over the presence of infesting entity
and to settle the consequence of the targeted actions to pest control.
