Cercetări asupra populației de carabide din plantațiile pomicole de măr în funcție de agrotehnica aplicată

Abstract

The researches were conducted in an apple orchard in Falticeni locality, Suceava county (Romania). Two experimental variants were used according to the applied agrotechnical measure, namely: 1. grassed bands in orchard inter-rows using the species Bromus inermis Leyss and 2. grassed bands in orchard inter-rows using the species Bromus inermis Leyss and overseeding with the species Lotus corniculatus L. (birdsfoot trefoil). The observations were carried out periodically, from May to Sepember, when the captured material was collected from traps. Only the carabid species, which constitute the object of the present study, were retained for assessment. The structure and population dynamics of carabid species were evaluated over the whole observation period. For a most clear interpretation of the obtained results, various indices were calculated, namely: abundancy, constancy, dominancy, ecological signification index. Among the collected species were: Harpalus calceatus Duft., Harpalus tardus Panz., Harpalus pubescens Müll, Metabletus truncatellus L., Amara aenea De Geer, Anysodactilus binotatus F. etc.
