Sažetak
Preliminary results of the analysis of data on two bark beetle species were presented for the area of SW Slovenia. Period of 15 years of population density monitoring data for Ips typographus and 8 year period for Pityogenes chalcographus served as a basis for machine learning methodological approach analyzing gathered data to find dependencies between environmental data (such as exposition, age of lures in pheromone traps, average monthly temperature, monthly rainfall and more) and the number of trapped beetles (their population densities) in the former year's record. As a result of this study average monthly temperature and previous year's number of trapped beetles appeared to be the most important predicting factor for the next year's population densities. There also appeares to be a strong positive correlation between the N and E slopes and the number of I. typographus catches while the same relation existed between W and N slopes and number of trapped P, chalcographus beetles.
