Elemente tehnologice de utilizare a capcanelor cu lumină pentru monitorizarea şi combaterea insectelor dăunătoare

Abstract

Low efficiency of plant protection means is explained by the lack of a centralized forecasting system for the terms to carry out protective measures, lack of modern methods of obtaining primary data for making up reliable short-term forecasts for the development and spread of pests in agricultural agrocenoses. During last years investigations cowering the elaboration of new systems of integrated plant protection became more active by utilization biorational means of plant protection, and electro optic installations. A great attention is accords to elaboration and selection of sources- attractants and new electro optic structures whice must show a high attractively due to a specific irradiation spectrum and, thus, provide a maximum trapping of harmful insects. Application of the light traps is a more perfect method for phenology investigation of many important, in an economic aspect plant pest, and results of insects gathering can by used for elaboration short-term prognoses of insect pests development for rendering more precise the terms for craning out of protection measures. Further the light traps for insect can be used as an independent mean for plant pest combating. In combination with other methods to combat the use of light traps significantly reduces the number of flying pests, and thus caused them harm.
