Length of dispersal flight of European spruce bark beetle?

Question

I'm interested in length of dispersal flight of *Ips typographus*. I can barely find some information about dispersal distances, height of dispersal flight, but not at all information about how many days does it takes for one beetle to find suitable host in average? The only information I found is that it is highly variable (Forsse, E., & Solbreck, C. 1985. Migration in the bark beetle ips-typographus duration timing and height of flight. Z. Angew. Entomol. 100 (1). 47-57). I also know that it is weather dependent but this won't help me... thank you !!

Answer 1

When the beetles hibernate, it usually occurs 0-5m from the tree the beetle has grown up in. Additionally, within one day, the beetle can travel up to 750m within a forested area. They can go even further, greater than 8km in a non-forested area.
