Insect Net

Many insects cause direct and in direct damage to plants.Direct damage ranges from sucking liquid from the plants to marks on the leaves.Much more serious indirect damage is determined by the fact that some insects are carriers of viruses and this causes a reduction of production, fruit malformation and withering of the plant until it dies. The insects most frequently affecting plants (especially the tomato) are Trialeurodes vaporariorum better known as the “white fly” which transmits generic viruses, Bemisia tabaci and Frankliniella occidentalis which respectively transmit the Tomato Spotted Wilt Virus (TSWV) and the Tomato Yellow Leaf Curl Virus (TYLCV) Chemical and microbiological control means are undoubtedly effective in terms of their power for controlling insects, but before being killed by the insecticide used in the greenhouse, they prick the plant and transmit the Virus damage on tomatoes. To prevent insects from entering greenhouses, a sical barrier is now used. This is a woven mesh with different mesh sizes according to the insect to be defended from. This type of protection is used all over the world and prevents virus carrying insects from entering and keeps down insecticide treatment for controlling other harmful insects.
