For industrial scale production of the thorny carpet (2) can be used three techniques: A the construction of a single carpet (Fig. 1) produced with others of different geometric shapes by way of example but not limited to triangular square rectangular (Fig. 3) pentagonal hexagonal more diffusely n gon or round or oval circle semicircle sector circular segment to a circular basic circular segment with two bases in their regular (Fig. 5) or irregular shapes (Fig.1) that may be open with a cut for facilitating the placement around the plant (Fig. 7). B The construction of a thorny carpet (2) in the roll (6) (Fig. 6) of a minimum width of 0.5 cm up to 600 cm or superior if needed flexible material and adaptable to the surface of the soil or to the plant stem around which it is positioned. C The construction of a carpet (2) on a rigid support by use and the needs of the cultivar. All the above examples identify the basis on which are placed spines (1) needles and pins of different sizes lengths inclinations and different densities of positioning on the invention according to the type of insect that can attack crawling or walking the specific cultivars. In a preferred solution but not limiting it identifies location or quills diametric dimension of 0.65mm with a minimum of 0.1 mm and a maximum of 10 mm at the base tapering to the tip which has a preferred size of 10 6 m 2 which is generally considered the standard size of a pinhead. On the above mentioned media are positioned with a retention system of known art pins needles spikes (1) of heights and sizes which may be with the same or different densities and with or without ramifications (3) placements (see Fig. 1) variable inclinations according to the type of insect that we don t want to walk or crawl towards the plant under cultivation. Such coupling systems and retention suitably fixed to the support of flexible or rigid materials that can be breathable to allow the passage of rain or dew or mulching and more or l
