Spragšių (Coleoptera:Elateridae) gausumo tyrimai ekologiniame ir intensyviame ūkiuose

Abstract

Totally 561 click beetle specimens were caught during the study - 462 specimens were detected in agrocenoses with intensive farming system and the rest 99 were found in fields of the organic farm. Among six identified click beetle species three (Agriotes obscurus, A. lineatus and A. sputator) were recognized as common and were detected without exception in all pit fall traps in both farming systems. Adults of Agriotes obscurus were the most abundant in the study (208 specimens or 37.08 %). It was found that essentially the highest number of click beetle adult specimens has been determined in triticale field under organic farming system, and in oat agrocenosis with intensive farming system
