Fol. Hist.-nat. Mus. Matr. 8. 1982—83. A study of the Trichoptera of the Szalajka Valley near Szilvásvárad as indicated by light trap material KISS, Ottó Ho Si Minh Teachers' College, Eger ABSTRACT: (Untersuchung über die Trichoptera des Szalajka-Tales bei Szilvásvárad auf Grund des mit Hilfe einer Lichtfalle gesammelten Materials.) Der Verfasser untersuchte das Material der vom Matra-Museum im Jahre 1980 im Szalajka-Tal bei Szilvásvárad betätigten lichtfalle und es wurden 46 Arten gefunden, darunter die AllotTichia pallicornis EATON, die in der Fauna Ungarns neu ist, sowie die Arten Plectiocnemia brevis Mac LACHLAN, Neuwnia mficrus SCOPOLI und Limnephilus stigma CURTIS, die früher im Bükk-Gebirge nach nicht gesammelt worden waren. Die Angaben bezeichnen die Flugperioden der einzelnen Arten, die Individuenzahl, die Dominanzperhaltnisse und die Verteilung der Arten je Familie. Auf Grund der Flugperioden werden 3 Aspekte abgesondert. Auf Grund der ökoligschen und tiergeographischen Eigenarten werden die Faunenkomponenten in die nachstehenden Verbreitungsgrundtypen eingereiht: boréale, mitteleuropaische, europaische, holarktische, palearktische und eurosibirische Arten. Trichoptera in the Bükk Mountains were first collected by SÁTORI. It is the collecting work carried out from time to time by J. JABLONKAY and the National Light Trap Network that has been neteworthy since 1950 and the speies collected by them were indentified by S. ÜJHELYI. From time to time S. ÜJHELYI, К. PETRICH, M. RESKOVITS, S. TÖTH, A. VARGA, L. ZÖLD, J. OLÁH, mrs. OLÁH, Z. VARGA, H. STEINMANN, В. SZABÖ and the author also collected there. In the northern Szalajka Valley of cool microclimate the Mátra Museum continuosly had a light trap operated for capturing imagos of Trichoptera from March 15 — Nov. 15, 1980. The light trap was situated on the territory of the trout-farm, which is entirely shaded by Alnus glutinosa L. GART, and on the banks of the stream Petasitetum hybiidi DOST, can be found. The height of the loca lity is 400 m above sea-level. METHOD OF COLLECTING AND PRESERVING The light trap used consists of a 125-watt mercury vapour lamp and a protecting corver of 1 m in diameter. Under the lamp there is a collecting funnel, it is 40 cm in diameter, and leads into a glass bin. The distance between the corver and the funnel is 40 cm. Pure chloroform was used as killing agent and it was kept in a glass vial placed in the glass bin. The gradually evaporating chloroform acted as leathal agent all night. The light trap was handled by the leader of the troutfarm, G. SÁFRÁNY. The material caught was transported in boxes almost full of cotton-wool and 97
