The observations were carried out from 1984 to 1989 in Krynica (Beskid Sadecki, Western Carpathians) during the experiments concerning the utilization of pheromone traps against Xyloterus spp. and Pityogenes chalcographus under the mountain conditions. Drainpipe and screen traps baited with linoprax, chalcoprax , and mixture of lineatin and ethanol were used in these experiments. There were 7 species from the genus Rhizophagus found in traps. Their numbers, sex ratio, time of appearance, maximum of occurrence, and the correlation between their appearance and flight of Xyloterus spp. and P. chalcographus are discussed. The percentage of Rhizophagidae in the total number of trapped insects, other than Xyloterus spp. and P. chalcographus , was calculated and the selectivity of both types of traps used was evaluated. The numbers of Rhizophagidae were directly proportional to the distance between the traps. Zusammenfassung Zum Auftreten von Prädatoren der Gattung Rhizophagus Herbst (Col., Rhizophagidae) in Pheromonfallen In den Jahren 1984–1989 wurden Beobachtungen in Krynica (Beskid Sadecki, Westkarpaten) in Rahmen von Studien über verschiedene Aspekte der Ausnutzung von Pheromonfallen gegen Xyloterus spp. und Pityogenes chalcographus unter Gebirgsbedingungen durchgeführt. Dabei wurden mit linoprax, chalcoprax, Lineatin und Ethanol beköderte Kammrohr‐ und Barriere‐Fallen aufgestellt, in welchen 7 Rhizophagus ‐Arten gefangen wurden. Ihre Anzahl, Geschlechterverhältnis, Dauer der Flugphase, Maximum des Schwärmens und Beziehungen zum Schwärmen von Xyloterus spp. sowie P. chalcographus werden diskutiert. Im Rhizophagiden‐Anteil der Beifänge zeigten beide Fallentypen spezifische Selektivität. Eine direkt proportionale Relation zwischen der Rhizophagiden‐Anzahl und dem Fallenabstand wurde festgestellt.
