Justification of use of light electrical technologies for catching insects

One of the main tasks is preservation of a harvest since because of insects wreckers, diseases and weeds agriculture annually loses up to 30% of a harvest. Exist agrotechnical, biological, chemical, physics - mechanical and electrophysical methods of fight against insects wreckers. The advantage of an agronomical method is its profitability and ecological safety, and a shortcoming is low efficiency. The biological method is ecologically safe, but has limited use and essential economic expenses since it is necessary to part natural enemies of insects of wreckers. The advantage of a chemical method is the possibility of his use on big squares, the high efficiency, low cost, speed, but at the same time turns out ecologically dangerous production in a type of accumulation of carcinogens in a product. It is proved that pesticides, just as radiation, belong to chemical mutagens, cause the gene mutations capable to be transferred to the subsequent generations. At physics - a mechanical method the product turns out environmentally friendly, but this method has big labor costs and there are number of difficulties at his use on big squares. The electrophysical method (optical light traps) is the perspective direction, allowing to obtain full information on quantity and species of useful and mean insects in the protected agricultural grounds. Using blue and UF of light-emitting diodes it is possible to create energy efficient light traps for insects. At the same time there is an opportunity not only to monitor development and population of insects, but also to prepare from the caught insects an additional feeding up in poultry-farming and fishing farms since the caloric content of 100 g of dry mass of insects is 600-700 kcal and she contains 60-70% of protein.
