“…As parasitoids have different insect stages for diapause, the sensitive insect stages for diapause also vary between different insects. Trichogramma evanescens, Trichogramma embryophagum, Trichogramma principium, and Trichogramma minutum are pre-pupal diapause, and the sensitive stage of diapause is the larval stage [38][39][40][41]. Hoclcothorax testaceipes and Psyllaephaqus pistaciae diapause in the pupal stage, and the sensitive stage of diapause is from the mature larval to the pre-pupal stage [42,43].…”

The chalcid wasp Tetrastichus septentrionalis Yang (Hymenoptera: Eulophidae) is one of the dominant pupal parasitoids of Hyphantria cunea (Drury) (Lepidoptera: Erebidae). In this study, the photoperiod’s effect on diapause induction in T. septentrionalis using the alternative host Tenebrio molitor was measured, revealing that T. septentrionalis is of the long-day type. The critical photoperiods for diapause induction in T. septentrionalis were estimated to be between photoperiods of 13:11 and 14:10 (L:D) h at 18 °C, and between photoperiods of 12:12 and 13:11 (L:D) h at 21 °C and 24 °C. We also found that T. septentrionalis diapausing larvae were grey-brown, while normally developed (non-diapausing) individuals were light yellow. The diapause-sensitive insect state was the larval stage, and the short light exposure treatment had a significant cumulative effect on diapause induction. The least squares method was used to calculate a lower developmental threshold of 13.34 ± 0.50 °C and an effective cumulative temperature of 184.46 ± 11.46 d·°C for post-diapause development. The average supercooling point of diapausing mature larvae was significantly lower than that of non-diapausing ones. Our research on T. septentrionalis provides a reference for the biological control of H. cunea and other leaf-eating pests.

“…The lower temperature threshold for T. telengai pre‐imaginal development obtained in our experiments (about 5°C) is lower than those observed in other Trichogramma species: about 8°C for T. brassicae (Negahban et al., 2021), 9–12°C for T. chilonis (Haile et al., 2002; Ghosh et al., 2017), 9.2°C for T. evanescens (Haile et al., 2002), 9.3°C for T. cordubensis (Ghosh et al., 2017), 10°C for T. buesi (Reznik et al., 2009), 10–11°C for T. pretiosum and T. annulata (Maceda et al., 2003; de Oliveira et al., 2017; Zuim et al., 2017), 10.3–14.5°C for T. japonicum (Ruan et al., 2018; Ghosh et al., 2017), about 10.5°C for T. achaeae (del Pino et al., 2020), 10.7°C for T. ostriniae (Wang et al., 2004), 11.8°C for T. turkestanica and T. principium (Hansen, 2000; Reznik & Voinovich, 2015), 12.0°C for T. kaykai (Hohmann & Luck, 2000) and 13.6°C for T. galloi (Cônsoli & Parra, 1995). This difference can be possibly explained by that the studied strain of T. telengai originated from Moscow province, which is far to the north of geographic ranges of above listed species.…”

“…Effects of temperature on various biological parameters of Trichogramma wasps were investigated by many authors (e.g. Chen et al., 2021; Cônsoli & Parra, 1995; Firake & Khan, 2014; Haile et al., 2002; Hansen, 2000; Hohmann & Luck, 2000; Negahban et al., 2021; de Oliveira et al., 2017; del Pino et al., 2020; Reznik & Voinovich, 2015; Ruan et al., 2018; Ghosh et al., 2017; Wang et al., 2004; Zuim et al., 2017). In particular, it is known that facultative (winter) pre‐pupal diapause is induced by low temperature experienced by Trichogramma embryos and larvae.…”

It is well known that photoperiodic induction of insect diapause can be affected by temperature, whereas photoperiod-independent diapause-inducing thermal responses received much less attention of researchers. We studied the influence of a wide range (from 3 to 30°C) of constant and alternating temperatures on the rate of development, on pre-adult survival and on the induction of pre-pupal diapause in the egg parasitoid Trichogramma telengai. The progeny of females developed at 20°C and photoperiod of L:D = 18:6 or 12:12 was used in this study. The study showed that the pattern of the thermal response of T. telengai is an asymmetric inverted U-shaped curve determined by two different mechanisms. The right part of the curve represents S-shaped effect of temperature on the induction of diapause (the threshold for this response is 13-15°C depending on maternal photoperiod), whereas the left part represents an arrest of development caused by the direct effect of low temperature (with the threshold of about 5°C). We conclude that the effect of temperature on the induction of diapause in T. telengai is based on (or at least closely connected with) the thermal influence on the rate of metabolism and development. The results of this study can be used for the prediction of Trichogramma diapause incidence under natural conditions and for the development of the cold storage methods.
