Development of the double-spined spruce bark beetle Ips duplicatus (Sahlberg, 1836) was investigated using the sandwich method under long-day conditions (LD 18 : 6 h) at 10 constant temperatures: 7, 10, 12, 15, 20, 25, 30, 33, 35 and 39 °C. The method proved unsuitable at lower temperatures (7–12 °C), where high mortality occurred. At higher temperatures, development from egg to eclosion of adults shortened from 39.0 days at 15 °C to 10.3 days at 30 °C. Temperatures over 33 °C were lethal to all eggs, larvae and pupae. The developmental rate increased linearly at temperatures between 15 and 25 °C. Stage-specific parameters, such as upper and lower developmental thresholds and optimum temperature for development, were determined by linear and nonlinear (Logan-Lactin) models. Lower developmental thresholds obtained from nonlinear regression were calculated to be 9 °C (eggs), 6.1 °C (larvae), 6.9 °C (pupae) and 6.3 °C (development from eggs to pupae). Upper developmental thresholds for all stages oscillated around 39 °C and optimal temperatures oscillated around 30 °C. The rapid development of I. duplicatus at 15 and 30 °C [10 and 4 days faster than Ips typographus (L.), respectively] may explain its recent outbreak dynamics and low effectivity of preventive control measures.
