Lymantria monacha (L.) (Lepidoptera: Lymantriidae), the nun moth, is a Eurasian pest of conifers that has potential for accidental introduction into North America. To project the potential host range of this insect if introduced into North America, survival and development of L. monacha on 26 North American and eight introduced Eurasian tree species were examined. Seven conifer species (Abies concolor, Picea abies, P. glauca, P. pungens, Pinus sylvestris with male cones, P. menziesii variety glance, and Tsuga canadensis) and six broadleaf species (Betula populifolia, Malus x domestica, Prunus serotiaa, Quercus lobata, Q. rubra, and Q. velutina) were suitable for L. monacha survival and development. Eleven of the host species tested were rated as intermediate in suitability, four conifer species (Larix occidentalis, P. nigra, P. ponderosa, P. strobus, and Pseudotsuga menziesii variety menziesii) and six broadleaf species (Carpinus caroliniana, Carya ovata, Fagus grandifolia, Populus grandidentata, Q. alba, and Tilia cordata) and the remaining 10 species tested were rated as poor (Acer rubrum, A. platanoidies, A. saccharum, F. americana, Juniperus virginiana, Larix kaempferi, Liriodendron tulipfera, Morus alba, P. taeda, and P. deltoides). The phenological state of the trees had a major impact on establishment, survival, and development of L. monacha on many of the tree species tested. Several of the deciduous tree species that are suitable for L. monacha also are suitable for L. dispar (L.) and L. mathura Moore. Establishment of L. monacha in North America would be catastrophic because of the large number of economically important tree species on which it can survive and develop, and the ability of mated females to fly and colonize new areas.
僧尼舞毒蛾（Lymantria monacha (L.)，鳞翅目：毒蛾科）是一种危害针叶树的欧亚害虫，有可能意外传入北美。为了预测这种昆虫如果传入北美后的潜在寄主范围，研究了僧尼舞毒蛾在26种北美树种和8种引入的欧亚树种上的存活和发育情况。七种针叶树种（科罗拉多冷杉、欧洲云杉、白云杉、蓝云杉、带有雄球花的欧洲赤松、西黄松变种glance和加拿大铁杉）和六种阔叶树种（纸皮桦、苹果、黑樱桃、裂片栎、红栎和绒毛栎）适合僧尼舞毒蛾的存活和发育。所测试的寄主树种中有11种被评为适宜性中等，四种针叶树种（西方落叶松、黑松、西黄松、北美乔松和花旗松变种menziesii）和六种阔叶树种（卡罗来纳铁木、卵果山核桃、大叶山毛榉、大齿杨、白栎和心叶椴），其余10种测试树种被评为不适宜（红花槭、挪威槭、糖槭、美国鹅掌楸、北美圆柏、日本落叶松、北美鹅掌楸、桑、火炬松和平展叶松）。树木的物候状态对所测试的许多树种上僧尼舞毒蛾的定殖、存活和发育有重大影响。几种适合僧尼舞毒蛾的落叶树种也适合舞毒蛾（L. dispar (L.)）和马图拉舞毒蛾（L. mathura Moore）。僧尼舞毒蛾在北美定殖将是灾难性的，因为它能在大量具有经济重要性的树种上存活和发育，而且交配后的雌蛾能够飞行并在新区域定殖。
