Summary of the Express Pest Risk Analysis for Massicus raddei Kusama, 1973
PRA area: Poland
Describe the endangered area: The entire PRA area (including urban area, field copses and areas where oaks grow)
Main conclusions
The plant pest M. raddei is harmful for oaks and causes serious economic losses in China. There are two important oak species in Poland- common oak (Q. robur) and sessile oak (Q. petrea). All oaks species are endangered if M. raddei occurs in PRA area.
The impact of pest in PRA area depends on its feeding preferences. If pest find host plants in Poland, it will negatively affect forest ecosystems and associated with them economic sectors.
M. raddei nowadays is a pest of minor importance for oak species in Poland but level of uncertainty of assessment is high. The climate conditions in PRA area seems to be suitable for this pest.
It is essential to devise methods of pest and disease detection in case of M. raddei occurrence in PRA area. All infected material should be disposed.
M. raddei is a large beetle because of that identification is easy and eradication measures (the light traps have successfully captured beetles) should be efficient.
