In fact, Cipollini et al. 2017 note that the success of EAB development in cultivated olive is higher than in more resistant native Fraxinus spp. hosts, such as Manchurian ash (F. mandshurica); however, EAB does not develop as successfully in olive as it does in favored North American ash species. In Massachusetts, the primary host trees are white ash (Fraxinus americanaRead More
