Sažetak
The increase of intercontinental traffic has increased the possibility of introduction of new poests. Arzone and Vidano (1990) state that in Italy an average two new pests are introduced each year. In Croatia a fast increase of introductrion of extic pests, mainly originating from North America, has also been registered. An early discovery can make their eradication possible, and is indispensable for slowing down their spread and for preparing optimal control measures. Therefore agronomists should be warned in time about such potential pests, especially the ones for which a positive forecast on the possibility of acclimatistation and of expressed harmfulness in Croatia can be given. The Japanese beetle (Popillia japonica Newman) is today the most dangerous plant pest threatening to be introduced into Europe. It is an important agricultural pest in the U.S. very numerous on the Atlantic coast near airports from where aircrafts often fly directly to European destinations. Therefore in dozen cases the beetles were found at some European airports where they were successfully eradicated. Recently the beetle was introduced into the Azores where an eradication project is in progres. The Japanese beetle is a quarantine pest on the A-1 list (CABI-EPPO, 1996), and is a quarantine pest for Croatia aswell. Some authors (Bourke, 1961, Mayer, 1961, Primault, 1962) have analysed the possibility of acclimatistation of the Japanese beetle in Europe. As very suitable for their acclimatistation and mass appearence they consider some valleys in Central Europe and as moderately suitable other parts of Europe including the part of Croatia sizuated north from the line Pula-Karkobag-Udbina. In this old analysis only a few biometeorological and climatic parameters were used. CAPI-EPPO (1996) state the acclimatistation possibility in Europe between the 43rd and 53rd parallel west of the 30th meridian. We have made a more precise analysis of the possibility of acclimatistation and harmfulness of the Japanese beetle in Croatia. According to Fleming (1972), Tashiro (1992) and others the quantity of rain and the temperature of soil (10 cm deep) in June, July and August, the minimal and average temperatures of the soil (10 cm deep) during the winter months and the average temperature of air in July were chosen as biometeorological parameters. These five parameters were compared to the corresponding climatic data of eight representative localities in Croatia. The analysis show that, if introduced, the Japanese beetle will acclimatise, propagate and become an important pest in the northwest part of Croatia and in Hrvatsko Primorje. The central part of Croatia is also favourable for the development of this pest. In the eastern parts of Croatia and Istria climatic conditions are less suitable. In Gorski Kotar and Dalmatia the Establishment of the Japanese beetle will not be possible.
