Abstract
The aim of this research was to give an overview of the biology of oriental chestnut gall wasp
(Dryocosmus kuriphilus), find the sites where it is present, estimate infection rates and prognose its
future spread in sweet chestnut stands in Croatia. Oriental sweet chestnut gall wasp was first recorded
in Croatia in 2010, and in 2011. it had spread to new localities. The wasp has one generation per year.
The infection rates on all sites was estimated and the highest infection rate was in the Zagreb area. The
spread forecast for Croatia for the following years is given. Intensive spread can be expected in all areas
where sweet chestnut is grown.
