Effects of proportion of host trees in forest stands on infestation intensity by the invasive oak lace bug, Corythucha arcuata (Say)

In a joint study in five Central and Southeastern European countries, we studied the effect of tree species richness on leaf damage caused by oak lace bug, Corythucha arcuata (Say) (Heteroptera, Tingidae), an invasive pest on oak trees that has spread rapidly across the Balkan Peninsula and Central Europe. Intensity of infestation by C. arcuata on oaks was assessed on three or four study plots with high and three or four plots with low percentage of oak in each country.
