Abstract: The potential range of forest pest species can depend on climate conditions. Predicting the effects of climate on insect species may be complicated, however, by the need to translate routinely collected meteorological data into microclimate measurements. For example, tree-boring beetles which spend the winter months in the under-bark microclimate (e.g., emerald ash borer (Agrilus planipennis Fairmaire), mountain pine beetle (Dendroctonus ponderosae Hopkins)) may experience minimum temperatures that tend to be warmer than air temperature minima. Moreover, the magnitude of the difference between under-bark and air temperature minima is variable, meaning that models of under-bark temperature cannot assume a constant level of thermal buffering.
