The prompt territorial diffusion Diabrotica virgifera in the countries next to Ukraine, in particular with the Zakarpatye region (Hungary, Romania, Slovakia), demands realization of careful monitoring in boundary territories.

For this purpose in middle of July 2001 lengthways near border with Hungary, Romania and Slovakia in 22 populated localities, and also in villages of the central part of region on sowings of maize were exposed pheromone traps and color (yellow) traps.

The traps were exposed on edges of a maize field on approximately through every 1000 meters, alternating yellow plastic cylindrical traps, yellow cardboard rectangular traps and pheromone traps. The pheromones of the Hungarian and Moldavian production were used.

At analysis of August 15 of a biological stuff in traps with the Hungarian and Moldavian pheromone first four specimens of Diabrotica virgifera were revealed in three frontiers populated localities.

Thus, with the help of pheromone traps exposed on sowings of maize along border, it was possible to reveal appearance first individual specimens on terrain of the Zakarpatye region that testifies that the depredator closely has come nearer to Ukraine.
