Thysanoptera community of midfield shelterbelts of different age

The density and species composition of Thysanoptera were estimated in three shelterbelts with different age located in arable land (Turew area, West Poland). It was stated, that 100 years old shelterbelts supply favorable habitats for the community of these insects: the occurrence of species connected closely with the shelterbelt and the stable species composition were found there. In the young shelterbelt (two years after planting). Thysanoptera constituted a community dynamically changing. In several (7–8) years old shelterbelt the community of these insects showed the features characteristic for community noted in 100 years old shelterbelt.
