Dynamika łowności Harpalus rufipes DE GEER [Coleoptera: Carabidae] w jednorocznych uprawach rolnych w zależnosci od typu gleby

In the years 1990-1991 changes in the abundance of Harpalus rufipes in one-year-old cultivated fields on four types of soils were studied in central Poland. The number of individuals caught on particular types of soil was statistically significantly different. A statistically significant relationship between the number of individuals caught and the share of mechanical fractions in soil was found as well as a statistically significant relationship between the number of H. rufipes individuals caught and the content of C, K, Mg and N and Ca in soil. No statistically significant relationship between the kind of plant cultivated and the number of H. rufipes individuals caught was found. The peak activity of H. rufipes imagines was very visible and occurred in July or August.
