Intensive using pesticides does not result in a considerable reduction in yield losses from insect pests. One of the alternative directions of biological plant protection is using pheromones of insects. Disorientation of male pest insects by pheromones is a main way to adjust the population numbers. Among the methods to deliver of synthetic pheromone preparation into the environment it is proposed to use a property of some electrostatic powders to adhere to cuticle of insects that bring the pheromone preparation by contacts interactions of insects. In laboratory and field conditions studied were biological and technological aspects of blocking the propagation of click beetle (Agriotes tauricus Heyd.) under autodisorientation. The experiment involved synthesized components of sexual pheromone of the click beetle. The influence of 3 types of carries were studied: metals (aluminum and bronze) and powdered graphite. The insects treated with powdered graphite completely die after 24 h. The biological activity of the method of autodisorientation was estimated during mass flight of beetle Agriotes tauricus Heyd in the production corm crops by means of pheromone traps KNIFANM=2. studied were 3 varinats of arranging autodisorientation devices on the area 1 ha: 4, 9 and 16 pieces. The field records were made every 3-4 days. The initial moment of arrange the traps was notable when autodisorientation devices were 9. When autodisorientation devices reached 16, the level of autodisorientation reached 68%
