Thermo-energetic model for autecological risk assessment and remote monitoring of spruce bark beetle populations.
Abstract
A topoclimate model, related to developmental features of the common spruce bark beetle species, Ips typographus and Pityogenes chalcographus, is generated. It is based on the effective temperature sum indices of the insects, and on the extrapolation of meteorological data, collected in a reference station, to the effective cambial temperature sums, received by spruce trap trees in differently exposed sites. Application of this thermo-energetical model on the digital landscape model, or on appropriate data sets of the forest area, should allow the assessment of bark beetle voltinism patterns as well as the actual progress of brood development, due to climatic conditions of the site and to the preceding weather conditions, respectively in mountainous spruce forests.
