• Faunistic research
• from Scopoli (1772), Schrank (1781) to the
  present
• 201 recorded faunistic works
• Slovakia 59 Ukraine 19
• Hungaria 45 Austria 15
• Romania 46 Poland 9
• past Yugoslavia 8
• - grey literature - local faunistic papers may
  still be hidden
• - a few works reflecting regular collecting
  activity
• problematic validity of published, especially
  historical data

Conclusions 711 species of 12 families in CB
near to actual species richness exploration
within CB uneven and insufficient - significant
number of species was recorded in single
finding - fauna of many orographic units and
nature preserved areas unknown future
objectives 1. data recovery from grey
literature 2. revision of historical/published
data 3. study of local museal collections 4.
extensive study of local faunas using effective
collecting methods (e.g. Malaise trap) 5.
taxonomic elaboration of problematic taxa (e.g.
Nematinae, Tenthredininae) 6. ecological,
zoogeographic studies - ecosozological
evaluation
