disclosed in the previous section as well as over the canopy layer. The braconids are relatively well-flying insects, hence, supposedly, their adherence to a plant layer is rather inexpressive compared to insects with worse or no flying ability. If braconids prove to occur in a relatively high number in any one plant layer that apparently shows a close relation to their egg laying activity as parasitoid agent of a phytophagous host (e.g. caterpillar, beetle etc. larva) living in a layer prefered. MATERIAL AND METHOD The braconid wasps (parallel with other insects) had been collected in the Turkey oak-sessile oak forest in the year of 1987 during the vegetation season from April to November. The braconids were gathered with a semi-automatic facility, i.e. with Malaisetraps 3.5 m high each. Corresponding to the shrub and canopy layers two Malaise-traps were set up in a meteorological tower and the third trap was standing on the top of the tower over the canopy - consequently, the three traps gathered the braconids at the heights 0-3 m (herb and shrub layers), 12-14 m (canopy layer) and 25-27 m (over canopy or over the tree crown). The fourth Malaise-trap was erected in a meadow (Festucion) about 200 m from the edge of the forest in order to have comparative data about the flying activity in the open area, namely in the meadow near to the ground and over the tree crown about 25 m in the height. - The Malaise-traps had been controlled and the trapped insects emptied every day. The hymenopterous insects were preserved dry in vials assorted according to their emptying from the traps. After finishing the field investigation, i.e. the stratified trap sampling, all hymenoptera were mounted and labelled with necessary collecting data. RESULTS Altogether 326 braconid specimens belonging to 60 species had been collected in the Síkfőkút oak forest during the vegetation period 1987. Though the 60 species seem to be small (in Hungary there are living at least 1200 braconid species), from among them four species proved to be new to the fauna of Hungary, they are as follows: Ascogaster grahami Huddleston, Colastes pubicornis (Thomson), Cotesia cleora (Nixon) and Macrocentrus flavus Snellen van Vollenhoven. Furthermore, three species distributed very sporadically around its entire area were caught by the Malaise-traps, they are as follows: Doryctosoma paradoxum Picard, Microtypus trigonus (Nees) and M. wesmaeli Ratzeburg (in Hungary they are listed from a few localities only). In the subsequent table (Table 1) 60 braconid species are enumerated (in the left column) in alphabetical order according to their generic as well as species names. Right to this, the collecting data of the species (month, day: specimens in sexes) broken up (in four columns) according to the plant layers or height of collecting in the oak forest association and the neighbouring meadow are presented:
