Bucculatrix ainsliella Murtfeldt, a new North American invader already widespread on northern red oaks (Quercus rubra) in Western Europe (Bucculatricidae) Naturalis
Nieukerken, E.J. van; Doorenweerd, C.; Ellis, W.N.; Huisman, K.J.; Koster, J.C.; Mey, W.; Muus, T.S.T.; Schreurs, A..
Bucculatrix ainsliella Murtfeldt, 1905 is for the first time reported from Europe: the Netherlands, Belgium, and adjacent Germany. DNA barcodes confirm its identity. It is the first North American lepidopteranspecies feeding on northern red oak Quercus rubra ever found in Europe, and only the second North American oak-feeding insect found in Europe. The species has regularly been found in the Netherlands and northern Belgium since 2006, and in 2011 also in Nordrhein-Westfalen in Germany, adjacent to the Dutch border, but the earliest records are from the Netherlands, Amersfoort in 1989 and 1990. Early stages, leafmines, and the adult are described, illustrated, and diagnosed against oak-feeding Bucculatrix ulmella Zeller, 1848 and other similar species....

Seed conditioning of red oak: a recalcitrant North American seed Scientia Agricola
Struve,D.K..
A ten day aerated water soak was developed as a seed conditioning treatment for red oak (Quercus rubra L.). Conditioned seeds had higher germination completeness, uniformity and speed compared to control seeds. Seeds could be conditioned under a wide range of temperatures and durations. Conditioned seeds were maintained at 7(0)C for 30 days without loss of seed quality. During conditioning, pericarps split in response to seed hydration. Split pericarps could be used as a pre-sowing indicator for high quality seeds. Seed conditioning was ineffective on dormant seeds. Increased crop uniformity and higher stand establishment can be realized by subjecting red oak acorns to an aerated water soak treatment followed by selecting seeds with split pericarps. These...
