Structure, dynamics and abundance of coleoptera species in sweet and sour cherry plantations from Iaşi and Vaslui counties, Romania

Abstract

The paper brings contributions to the knowledge of fauna of beetles (Coleoptera) in some ecosystems of sweet and sour cherry from Iaşi and Vaslui counties, Romania. For catching insects from orchards two methods have been used: the sampling with the Barber soil traps method, six traps placed in each experimental group, which were fixed with a salt solution (NaCl) 5%, and the beating method, where insects collected were kept and preserved in alcohol 90°, and after them, the insects collected were pooled and brought to the laboratory, where they were prepared for determination. During the vegetation, at Barber soil traps the insects have been collected in sweet and sour cherry plantations, where various control methods have been applied. From the collected material, Coleoptera species were selected, and were determined by species. Among the most common Coleoptera have identified: Stethourus punctilum Weisse, Carabus violaceus L.; Silpha obscura L., Cymindis humeralis Fourc., Apion atomarium Kirby, Otiorrynchus ovatus L., Dermestes laniarius Illig., Harpalus calceatus Duft.
