In 12 study objects there were 67 Elateridae species caught, in which 62 mature insects and 6 larvae, belonging to 9 species. In view to similar ways of response by larvae and imagines to a longterm industry-borne pression, both those stages were subject to a joint elaboration (Table 1). The Elateridae set in pine stands of the Koniecpol object is under a lesser impact of man, while the sets from the stands of Rajgrod, Szczebra, Augustow, and Browsk regions, where sample plots were under the least impact of airborne pollution (Ⅰ zone), are still less suppressed. The Elateridae sets found in pine stands near Ostrow Mazowiecka, Swierklaniec, and Kampinos localities are under the greates manmade impact. If features of Elateridae sets are considered as distributed by individual zones of pollution, then the least manmade disturbance to those sets is to be found in the first zone, while greater in Ⅱnd, and Ⅲrd zones. In pine stands within the reach of slight airborne pollution (Ⅰst zone) there the specific richness increases from the north to the south, while a reverse tendency appears in the naturalness of insect sets. In the third zone, where pine stands are exposed to a strong impact of pollution, there the occurrence of ubiquitous species was not found. This zone is characteristic for its least number of species and the greatest number of individuals, as well as for the greatest share of facultative saprophages and the least one of phytophages. In the remaining zones there the shares of trophic groups are different. The airborne pollution causes a decrease in the domination of zoophages, because they are sensitive to industrial emissions more than the remaining trophic groups.
