ABSTRACT
In managing the corn crop, European farmers frequently face the presence of the pest Diabrotica v. virgifera, which has a negative impact on production. Since 1992, various attempts have been made to limit its expansion and multiplication. In recent years, with the elimination of the most used chemical insecticides, farmers had to resort to non-aggressive and less polluting methods. Therefore, in this paper, an attempt was made to find a solution available to anyone to reduce the adult population level in maize crops. Knowing that adults are responsible for long-distance movements, it was deemed appropriate to focus on the use of both colored and pheromone traps for detection, monitoring and capture. The testing of the traps was carried out in 2020 and 2021, between June and September in two culture systems, organic and classic, belonging to an agricultural company from an area of interest in Western Romania. Following these studies, it was found that in the ecological culture, corn catches were 1.8 times higher than in the classic culture. Dual-attractant (color and sex pheromone) pheromone traps were the most effective in both crop types, with a capture efficiency of 90.65% of capacity, while in colored traps without sex pheromone it was only 60.0%. Pheromone-only traps had intermediate efficiency, with a capture capacity of 72.68%. In conclusion, traps with double attractiveness, both in color and in the presence of pheromone, are a viable solution in managing the pest.
