ДЕЯКІ ОСОБЛИВОСТІ СЕЗОННИХ ЦИКЛІВ НАПІВТВЕРДОКРИЛИХ (HETEROPTERA) УРБОЦЕНОЗІВ МІСТА ХАРКОВА

Abstract

The article deals with the analysis of the data on the individual characteristics of the life cycles of Heteroptera recorded in the urban cenoses of Kharkiv. In terms generations, three phenological groups were distinguished and five phenological groups – on the basis of the wintering stage. At the imago stage, 114 species hibernate (69.51% of the entire heteropterofauna), of which most species belong to the families Lygaeidae (37), Miridae (14) and Pentatomidae (22 species), Nabidae, Tingidae, and Rhopalidae (seven species each). At the egg stage, 42 species winter (25.61%), mainly from the Miridae family (34 species), fewer – Lygaeidae, Nabidae, Rhopalidae (two or three species each). At the larval stage, only four species (2.44%) from the Pentatomidae (3) and Reduviidae (1 species) families hibernate. Two species from each group hibernate at the stages of imago and larvae, eggs and larvae. A small number of such species can be explained by the fact that the conditions for wintering at these stages are less favorable in temperate latitudes (Eastern Ukraine). The group of monovoltines includes 107 species of bugs (65.24%). The bivoltine and multivoltine groups are represented by 32 (19.51%) and 24 (14.63% of the entire hetero-fauna) species, respectively. As for Coriomeris denticulatus, the number of their generations per year has not been established.
