A total of 257 966 specimens from 149 catches of drosophilid flies from Switzerland, belonging to the 34 most frequent species are considered here. The records are screened for effects of environmental factors (geographical region, altitude, season, habitat, soil, climate) on the size and diversity of the samples. Furthermore, the individual species are compared with respect to frequency and diversity, and to the effect of the above factors on their proportions in the samples. Zusammenfassung Aus dem Vergleich von 149 Proben von Drosophiliden, die zwischen 1946 und 1984 an 59 Orten der Schweiz über gärenden Bananen geködert worden waren und insgesamt 257 966 Fliegen ergaben, wird erkennbar, welche Umwelteinflüsse sich sowohl auf die Zusammensetzung der Proben nach Arten samt deren Häufigkeit wie auch auf das Vorkommen jeder einzelnen Art auswirken.
