• Heteropterans occupy a wide range of habitats characterized by pronounced seasonality of environmental conditions. In the temperate zone, they use different seasonal adaptations to survive and successfully utilize resources under these sometimes severe circumstances. To review the known adaptations, we use two approaches. First (as suggested by Tauber et al., 1986), all seasonal adaptations are divided into three categories (dormancy, seasonal migration and seasonal polyphenism) with further subdivision of each category into diapause-mediated and non-diapause responses. We suggest here an alternative approach based on the four seasons of the yearly cycle when these adaptations either used by insects or at survival of which these adaptations are aimed to. In the group of winter adaptations, we discuss basic traits of winter diapause (metabolic parameters, facultative and obligatory nature, photoperiodic induction, sensitive stages, temperature dependence, geographical variation of photoperiodic response, use of host plant status and temperature as alternative cues for diapause induction, cold-hardiness etc.). The spring complex of adaptations has been less studied and includes different types of post-diapause photoperiodic sensitivity that are evidently adaptive under different circumstances. As summer and autumn adaptations, we discuss summer diapause, photoperiodic control of nymphal development and coloration of nymphs and adults, behavioral adaptations and migration. Some general considerations and directions for further research are also given.
