Great progress has recently been made in cryobiology. One field, however, has been neglected: the temporal sequence of the effects of photoperiod and temperature, and their relative importance in cold hardening. This is relevant to the question of impor- tance of diapause in cold-hardiness. Denlinger (1991) outlined the categories of such relations and stressed a great need for further detailed research. A survey of studies done over the past decade revealed many gaps in the evidence and the ambiguous nature of the data on the photoperiodic regulation of cold-hardiness. We hope that this review will stimulate further research in this field. Among several directions where research is most needed we have stressed (1) simultaneous recording of changes in survival and dynamics of suspected cryoprotectants (stressed also by Danks, 1996), (2) checking the regulation of different phases of cold hardening, and (3) discrimination between direct and indirect (mediated via neuroendocrine system) effects of environmental cues on cold harden- ing.

- Diapause research in insects: historical review and recent work perspectives (2019, background): “…artificial environments (van Lenteren & Tommasini, 1999), because cold storage generally has negative effects on life histories (van Baaren et al., 2005; Colinet & Boivin, 2011; Ismail et al., 2014), and because diapause does not necessarily increase insect cold tolerance (Hodkova & Hodek, 2004).”
- Reorganization of membrane lipids during fast and slow cold hardening in Drosophila melanogaster (2006, background): “…rapid cold hardening takes place in both winter- and summer-acclimated insects ( Powell & Bale, 2005 ), and other factors such as photo-period could also play a role in both the regulation of phospholipid fatty acid composition and cold hardiness ( Harwood & Takata, 1965; Hodkova & Hodek, 2004 ).”
- How climate change affects the seasonal ecology of insect parasitoids (2020, background): “…an obligate (univoltinism) or facultative (multivoltinism) hormonally mediated and pre-programmed state of low metabolic activity characterised by arrested development, suspended activity, and increased resistance to environmental extremes (Tauber et al., 1986; Hodkova & Hodek, 2004; Koštál, 2006).”
- The elements of seasonal adaptations in insects (2007, background): “Rather, in several species at least some aspects of the diapause program are prerequisites for some aspects of cold hardiness (Denlinger 1991; Šlachta et al. 2002; Hodkova and Hodek 2004; review by Danks 2005).”
