Description of the industrial invention having for title: Infusion of Inula Viscosa having properties against hematophage insects, mosquitos, flies, horseflies. Name: Virruso Cosimo State of nationality: Italia resident in Casteldaccia (Palermo) viaMatteotti n. 5 Summary: the present invention refers to infusion of Inula Viscosa. It concerns the process to obtain the mentioned infusion in bath of ethilic alcool, vegetable oil, water. The liquid obtained from the infusions present a considerable activity against hematophage insects, mosquitos, flies, horseflies. State of the technique:
With the common noun of mosquito are indicated the different species of insects "Dipteron Nematocera" of the family "Culex". They have a thin body which is long from 3 mm to 15 mm, provided with antennas and long and thin legs. The males feed on sugary substance of vegetable origin, while the she- mosquitos need a rich in proteins diet, so they resort to the "feed of blood" preferring as "blood donor" the human specie. Many species are annoying only for the stings, while many others, in addition to the irritation of their stings, can pass pathologies more or less dangerous. The anopheles pass the plasmodium of the malaria, the mosquitos of the genus "aedes" pass the virus of the yellow fever and of the "dengue", for example. The changed standards of living and of habitat make sure that, owing to the movings from a continent to the other, some species territorialize regions and countries where they have been always absent, being a danger for the spreading of new pathologies. The mosquito-tiger, always absent, made her appearence in Italy in 1990 and she is already present in Lombardia, Liguria, Lazio, Veneto. Few living organisms could adjust to the changes in the environment, taking advantage of the progressive pollution as the mosquitos have done.

In fact their grubs, which are able to live in polluted waters, aren't any more attacked by the fishes, great predator of grubs, which don't survive there for lack of oxygen. The mosquitos need some chemichal and physical stimuli, one for example is the carbon dioxide produced in abundance by the man and animals during the transpiration.
This permits to the mosquitos to recognize, even from an interval of several hundreds of meters, the possible prey. In the short distance olfactory signals, as those which rise from the sweat or from the urina, supply the mosquitos with the pecularities of the prey.
The corporal temperature and the transpiration indicate them the point of attack.
Reached the prey by this way, the mosquitos begin their "feed of blood".For sucking blood from the body of the preys, the mosquitos provide for drilling of the skin executed by a series of alternate movements of the two jaws, next to which the alimentary duct and the salivary duct, ipopharinx, are situated.
Inserted her proboscis in the skin of the host, the mosquito injects her saliva which causes a vasodilatation which determines a greater afflux of blood.
The saliva of the insect, besides to produce an allergic reaction, can insert in the organism of the prey patogenic agents.
As said we deduce that it is absolutely necessary to limit as greatly as possible the development of this insect by a full and differentiated struggle.
This struggle has to be carried out, responsibly by all the organisms which operate in the community, particularly by public and private body: the public body in defence and care of the public spaces, the citizens in the private spaces of own competence.
The struggle is carried out by mechanical and chemical action and by defences of natural origin.
Mechanical action by the removal of all those conditions which create suitable conditions for the development of the mosquitos.
Sheet No. 3 Chemical action by insecticides aimed at the grown up insect or at grubs. By defences of natural origin, unguents, creams, various repellents in defence of the person, candles and others expedients to the essences of geranium, citronella etc like expedients in defence of the house. Aim of this invention is to obtain, by infusion, the enrichment of the liquids of the same infusions with substances of Inula Viscosa. These liquids, appropriately used, have carried out a significant and inhibitory action towards the olfactory system and the apparatus-sting of the mosquitos. Description of the invention:
The fnula Viscosa is a perennial plant of the family of the Composite, a little woody at the base and considerably branched. It is , in full, covered by a velum of grandular and microscopic hairs, which gives her the charatteristic stickiness. The leaves have lanceolate shape, dentate edges, and are sessile, stalkless. The yellow flowers are disposed in flower-head and form long and pyramidal clusters at the extremity of the stalk.
This plant, which was known in distant times for her antiseptic, antibacterial, hemostatic and cicatrizant properties, to day it is held in esteem for antimycotic properties of her substances. It is largely diffused in Italy, France, Spain, Turkey, Israel.
For the infusions, object of this invention, have been used parts of plant drawn in the area of Casteldaccia in province of Palermo.
Infusion n.l: 100 grams of vegetable oil in 50 leaves of Inula Viscosa, in erme tic pot for 48 h at room temperature. Infusion n.2: 100 grams of water in 50 leaves of Inula Viscosa, in ermetic pot for 48 h at room temperature. Irιfusionn.3: 100 grams of ethilic alcool in 50 leaves of Inula Viscosa, in ermetic pot for 48 h at room temperature.

It is possible, further, to mix the infusions with all those substances existing on the market for the struggle against these insects.
The substances of Inula Viscosa have been analysed by the "Dipartimento di Chimica farmacologica della Universita di Palermo" with a Cromatografy of mass by the following strument:
