374 DUNÁNTÚLI DOLGOZATOK (A) TERMÉSZETTUDOMÁNYI SOROZAT 11. (2002) samples personally, most of them were collected by lamp (mercury vapour bulbs, 125 or 250 Watt), powered by a portable generator set (small Honda). The result of these samplings was rather varied. The best samples contained 25-30 species of 1500-3000 specimens. Sometimes the number of species run up to 32-40, the number of specimens can run up to five thousand. The best results were achieved along the upper, unpolluted sections of larger rivers (Duna=Danube, Dráva) and around some stagnant waters with dense vegetation. An outstanding collection was carried out in Szigetköz, upper Danube region, where 2961 males and 3533 females of 40 species were taken during a two-and a-half-hour personal collection (Piiski, Zátonyi-Holt-Duna, June 21, 2001). Light traps sometimes captured material with more specimens (up to 50 000 one night), but less species. We used light traps as well for sampling caddisflies. First we used the caddisfly material of traps for general insect - mostly lepidopterous - collection, with chloroform applied as killing agent. Later, since the beginning of the 1990s we set traps just for caddisfly sampling, with ethylene-glycol as killing and conserving agent. Along the larger rivers and around large lakes such type of traps functioned periodically, rather than permanently. Their lamp was switched on only for some days a month, during the moonless nights. This way we wanted to avoid obtaining huge materials. However, such a periodical trap captured 60 000 adults during two years (Őrtilos, along Dráva river), or 110 000 adults during six years (Halászi, Moson Danube). We collected also at daytime by sweeping in riparian vegetation. Some caddisflies are on wing mostly at daytime, and are usually not attracted by light. We visited almost all regions of Hungary to obtain original samples. Our greatest activity spread over south, west and north Transdanubia, where we examined caddisflies of the Mecsek Mts., small brooks and streams of hilly and lowland regions, lake Balaton, and along the rivers Dráva and Danube. We also had the opportunity to visit Mátra Mts., Bükk Mts., Aggtelek National Park, other parts of the Northern Mountains, and the Great Hungarian Plain (mostly the smaller regions of the Hármas-Körös’ and the Szatmár-Bereg Plain) respectively, within the framework of certain scientific programs (or outside these), to collect many samples for caddisflies. In the Hungarian text we present the important results of these examinations in each region, also by citing papers concerning the areas studied. In Table 1 we give the number of species existing in Hungary per family, while the list of all Hungarian species (check list) is given in Tables 40 and 41 (in Appendix). All our collections are kept in diaries. Our field diaries contain all the important data of each collection. Other notebooks contain the data of light trapping and materials collected by other colleagues. In this chapter we introduce also our computing database designed by our son, P. Uherkovich. This database contains all data (date, locality, circumstances, method, collector, list of species and number of sexes) of our 11 196 samples. We can generate and access many types of lists about species, sites, as well as we can use the program for constructing activity graphs, etc. This database helps us draw distribution maps by the help of another computer program (also by P. Uherkovich). The most characteristic data of this database are given in Table 41 (in Appendix). The total specimens elaborated and recorded runs up to 758 337. (Another database was opened for foreign material, which is not discussed in this work.)
