Abstract: The Czech Republic is experiencing the third outbreak period of Ips typographus since 1880. The first and second outbreaks (1870-1876 and 1945-1954) were a consequence of falling of masses of trees caused by storm. References of Ips duplicatus during the first outbreak mentioned in later papers are erroneous, since the species involved was Ips amitinus.
The third outbreak from 1980 until now has not one but several human causes. These are: Falling of trees due to pollutions with SO₂, the increasing temperatures during the last 30 years and the development of higher numbers of generations of the beetle. The successes in using pheromones in the control of Ips typographus were overestimated. Also the changes in the ownership of forest stands were of importance.
Ips duplicatus occured in North Moravia having migrated across northern Poland to the eastern Czech Republic.
In the Nationalpark of Sumava (on the other side to the Nationalpark of Bavaria) in some reservations no measures against Ips typographus as in Bavaria were applied. Here new control measures must be taken against this pest.
