The OLBIE project focused on Corythucha arcuata (oak lace bug, OLB) (Heteroptera: Tingidae) an invasive Hemiptera introduced from its native range in North America into Europe, and which was first detected in Europe in Italy in 2000. Since its accidental introduction it has spread rapidly over a wide geographical area and is now found in over a dozen other European countries. In some countries, such as Hungary and Croatia its population has reached substantial levels where there is now serious concern that the pest may have significant impacts on oak health, as well as potentially increasing the susceptibility of oaks to other pests and diseases.

There is very limited published information on this particular insect species. Within its natural range in North America it is generally regarded as a nuisance pest, causing only incidental damage, although dense populations can cause premature leaf fall. Within Europe there is considerable variation in its reported impacts, hence there is a real need to understand what factors are influential in the development of this insect species and how it can damage oak. OLBIE aimed to address key questions and gaps in the knowledge of Corythucha arcuata, particularly in relation to the biology, dispersal, control and management options and the wider environmental impacts.
