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
