Factors influencing structures of assemblages of epigeic carabids (Col., Carabidae) populating some cereal plantations.

摘要

The species composition of epigeic carabids (Carabidae) in selected cereal crop plantations in Poland was studied, and the factors that can cause changes in the structures of assemblages of carabid beetles were investigated. Observations were carried out in the north-eastern part of Poland, in Tomaszkowo near Olsztyn (UTM DE65), from 2005 to 2006. Two fields selected for the experiment were under wheat and triticale. The results confirmed that the application of pesticides has some effects on the number and diversity of Carabidae populations in cereal plantations, and that the type of crop can also affect the assemblages of carabids that populate crops.
