Population densities and diversity of Noctuidae (Lepidoptera) along an air pollution gradient on the Kola Peninsula, Russia¹
The noctuid moths were monitored by means of bait traps from 1991 to 1993 in the area polluted by the Severonikel smelter on the Kola Peninsula. The total catch was 869 specimens belonging to 21 species. The catches peaked in sites representing the earlier stages of forest decline, being about two t...

| Summary: | The noctuid moths were monitored by means of bait traps from 1991 to 1993 in the area polluted by the Severonikel smelter on the Kola Peninsula. The total catch was 869 specimens belonging to 21 species. The catches peaked in sites representing the earlier stages of forest decline, being about two times as large as in the unpolluted area. The noctuid moths were heterogeneous in their response to pollution impact: (1) Xestia rhaetica, X. speciosa and Eurois occultus showed a clinal decline towards the emission source, (2) Diarsia mendica peaked at slightly polluted sites, (3) Acronicta auricoma, Hyppa rectilinea, Apamea maillardi and Xestia alpicola were most abundant in moderately polluted areas, (4) a mountain tundra species, Polia conspicua, was collected in heavily polluted sites only. However, neither species richness nor diversity of Noctuidae were affected by pollution. |
