Role of temperature and photoperiod in diapause regulation in Czech populations of Dolycoris baccarum (Heteroptera: Pentatomidae)

Dolycoris baccarum (L.) populations from the Prague region (52°N) display a facultative adult diapause. The induction of diapause is governed by photoperiod, long day averting it. High temperature tends to prevent diapause even under a short-day photoperiod.
