Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

Important pests of Scots pine within range of pollution from the Legnica-Głogów copper complex.

Abstract

Surveys in 1975-78 in stands of age class III-IV near the complex showed no dramatic increases in primary insect pests, though numbers of Bupalus piniarius and Acantholyda nemoralis [A. posticalis] increased in areas of severe pollution. An increase in certain predators (Elateridae and Carabidae) was also noted. Several pest species were observed in large numbers in younger stands. A serious increase in secondary pests was observed, notably Blastophagus [Tomicus] piniperda. The pattern of changes in insect species composition appears similar to that found around similar industrial complexes in southern Poland.
