Observations concerning the Coleoptera entomofauna where ecological control measures were applied

Abstract

Observations concerning the epigeous coleoptera found in apple tree plantations from the Fruit-Growing Research and Development Station of Fălticeni were done in 2008 from May to October, by means of Barber-type traps. A number of 10 samplings were carried out on the following dates: 30 May, 16 June, 30 June, 22 July, 1 August, 12 August, 25 August, 5 September, 18 September and 9 October. At each sampling, coleoptera species were separated by the rest of the material, the formol solution being replaced by another solution with the same concentration. During this period of observations, they collected 901 samples of coleoptera belonging to 56 species. The species with the highest number of collected samples were Pseudophonus rufipes De Geer (189 samples), Opatrum sabulosum L. (180 samples), Dermestes frischi Kugel. (78 samples), Ophonus puncticollis Payk. (67 samples), Cicindela germanica L. (56 samples), Harpalus distinguendus Duft. (43 samples), Otiorrhynchus raucus F. (37 samples), Psylliodes chrysocephala L. (34 samples), Pterostichus vulgaris L. (24 samples) and Staphylinus spp. (21 samples).
