The vegetation of allotment gardens is an important element of urban green areas and
constitutes a habitat where many groups of insects exist, including aphids. This research
involved the monitoring of winged morphs of aphids in allotment gardens in the area of
Poznań with the use of Moericke traps. The fauna structure of aphids in two large allotment
gardens was demonstrated by comparing the activity of winged morphs of aphids in
2000–2001 and 2014–2015. The vegetation of these gardens was accompanied by the rich
fauna of aphids. For four growing seasons, 113 species or groups of aphid species were
captured with the traps. Major changes were reported in the structure of the collected
fauna in the period of time when the research was conducted. The differences concerned
particular positions of collected species in aphid communities. The abundance of Anoecia
corni, Aphis sambuci, Phorodon humuli and Periphyllus testudinaceus increased, and
now hold the position of subdominants of the communities, whereas Myzus persicae and
Hyalopterus pruni decreased in comparison with the situation more than ten years ago.
Rhopalosiphum padi still remains an eudominant in the communities. The main reason for
this phenomenon is thought to be due to changes in the vegetation composition of gardens
because the gardens are being used differently. The production function has changed to
recreation.
