Anti insect screen or insect barrier is the ideal solution to reduce attacks by harmful insects that cause massive destruction of crops every year. insect barrier protects from all kind of insects coming from the outsides of cultivated field, ranging from larger ones (aphids, leafhoppers, whiteflies and others, such as those belonging to Diptera – flies and midges – and to Lepidoptera – butterflies and moths) to those very small (thrips). At the same time insect barrier defends crops from viruses. In fact viruses, unintentionally spread by insect bites during suckling, attack crops severely, leading to deteriorations of plants, resulting in significant production losses.
insect barrier controls thrips and other insects inside a greenhouse or in open field with supporting structures if needed. insect barrier screen protection significantly reduces the number of parasites under the net, while maintaining proper ventilation. Consequently it reduces pesticide treatments with important cost savings. It is light and extremely flexible so it is very easy to apply even directly on the crops, fitting to their shape and growing needs. It also protects from winds.
Anti-insect screen: optical and mechanical protection.
insect barrier impedes the access of insects in two ways.
- Optical protection: the insects are repelled by optical shielding additives present in the net. These non-toxic additives that filter light actually blind the insects which remain immobilized before they can reach the screen. Disorientation of the insects reduces the risk of attacking the crops. The optical properties are resistant over the years and last intact throughout the net life.
- Physical protection: the tiny micro fiber provides an efficient insect barrier. Meshes (mesh = number of holes per inch) are so narrow that even insects of the size of millimeters, such thrips, cannot penetrate. Holes are small enough to prevent insects from entering, but also big enough to let the sunshine and air passing through.
Scientific researches demonstrated that the presence of thrips under insect barrier is strongly diminished compared to control groups without an insect barrier.Anti-insect screen is a protection against virus diseases.
Insects are the main virus carriers. Blocking insects insect barrier also helps in preventing the virus that affect the crops.
In fact it is proven that it drastically reduces the quantity of pests: thrips and white butterfly, pepper mediterranean fly, aphids, among other parasites.
insect barrier is able to prevent infestations and the spread of diseases without overuse of chemical pesticides. Viruses are responsible for huge damages and expenses. They are very difficult to control and resistant to pesticides. Including massive spraying can turn out costly and inefficient. To save crops from whiteflies and other bugs infestations that cause destructive epidemic diseases, the valid alternative is to use an anti-insect screen to cover and protect the crops.
insect barrier is a proven effective method to protect market valuable crops such as tomatoes, cucumbers and beans, that are very sensitive to viruses transmitted by insects. Cucumber yellowing stunting disorder virus (CYSDV) actually attack all the crops belonging to the Cucurbitaceae family, including melons, squashes, pumpkins. It causes water stress and leaves loss, so fruits development is compromised. Any chemical intervention is worthless. Among the viruses that principally affect tomatoes plants are: Tomato Mosaic virus (ToMV) with a wide range of host plants, including weeds, Tomato Infectious Chlorosis virus (TICV), Tomato Chlorosis virus (ToCV) and Tomato Yellow Leaf Curl virus (TYLCV). Viruses are transmitted from infected plants to healthy ones through chewing insects.
Reducing the threats of insects, the need of spraying chemical products also decreases, allowing the growth of yield as more natural, nearly pesticide-free product. insect barrier methods require innovation, study and implementation of more effective and efficient solutions, due to the rapid evolution of pests that become resistant to pesticides.
A total protection can be achieved by applying an insect barrier in combination with an anti bird netting to block both insects and birds. The choice of the net – selecting the appropriate density of the mesh and color – must be based according to the local climate conditions and insect population. Hortomallas fabrics and provides innovative, new generation anti insect screens that combine physical and optical protection.
