The spreading rate and population numbers of recently introduced insect pests depends on a number of factors, especially temperature and precipitation, which are the key climate factors. Research into the effect of these factors was justified by the fact that climatic conditions in Bosnia and Herzegovina are not the same as conditions in the country of pest origin. The goal was to determine the effects through research over a nine-year period with concrete conclusions on the effect of climatic conditions on the pest expansion, overpopulation and damage. The research was conducted between 1997 and 2005. Data up to 2002 includes information of the spreading rate while data between 2003 and 2005 includes results on population density. The spreading rate was determined as follows: 20-25 km per annum until the year 2000, and 10-15 km per annum in years thereafter. Population numbers have increased but have fallen during the dry period of 2000 and 2003. It was determined that climate variability has a significant effect on the spreading rate and population density of the Western Corn Rootworm in Bosnia and Herzegovina.
