Wpływ zastosowania Nomoltu 150 dla zwalczania brudnicy mniszki w roku 2003 na występowanie Pterostichus oblongopunctatus i Pterostichus niger (Carabidae, Col.)

The use of Nomolt 150 in 2003 to control nun moth population had significant effect on the decline in the number of two abundant ground beetle species: Pterostichus oblongopunctatus and P. niger. The number of trapped insects in the area covered by control treatment was significantly reduced in comparison with the area where such treatment was not performed. This particularly referred to P. niger. While this common species occurred in great number before the treatment in each of three years of observation, it almost disappeared aftermath.
