Host plants of Anoplophora glabripennis
In USA, Anoplophora glabripennis (EPPO A1 quarantine pest) was discovered in New York in 1996 (EPPO RS 96/214) and later in Chicago (EPPO RS 98/200). In these cities, it attacks essentially maples (Acer platanoides, A. rubrum, A. saccharum, A. saccharinum, A. negundo, A. pseudoplatanus) and horse chestnut (Aesculus hippocastanum). But it can also be found on many other hardwood species: Betula, Populus, Salix, Ulmus, Fraxinus, Liriodendron tulipifera, Morus alba, Robinia pseudoacacia. In New York, it has been found on rose of Sharon shrubs (Hibiscus syriacus). Studies are being done to determine which North American tree species are suitable for larval development and adult maturation feeding. Using 55 plant species from 35 genera, preliminary results showed that adults preferred to feed on Acer platanoides, A. saccharum, A. palmatum, A. macrophyllum, Betula pyrifera, B. populifolia, Fagus grandifolia, Ulmus procera, Salix nigra. But Citrus, Pinus, Juglans, Liriodendron tulipifera were not liked. Oviposition and egg development were observed on the following species, but was higher in Acer saccharum, A. platanoides, A. circinatum, Betula alleghaniensis, Liriodendron tulipifera, Ulmus americana; ;than in: Acer macrophyllum, Alnus rubra, Betula nigra, Betula populifolia, Nyssa sylvatica, Populus tremuloides, Robinia pseudoaccacia, Salix babylonica, Sassafras albidum, Ulmus procera. It is not yet quite clear which are the trees on which A. glabripennis most successfully completes its life cycle. In addition, it remains (fortunately) contained within city areas and there is no experience of how it might behave in natural forests.
In China, A. glabripennis is mainly a pest of poplar (Populus) plantations. The major hosts are species and hybrids of section Aegeiros of the genus Populus: P. nigra, P. deltoides, P. x canadensis and the Chinese hybrid P. dakhuanensis. These poplars have been very widely planted in China in recent decades, which has favoured the multiplication and spread of A. glabripennis. Some poplars of the other sections of the genus (Alba and Tacamahaca) are also attacked, but are only slightly susceptible (Li ; Wu, 1993). Salix spp. (S. babylonica, S. matsudana) are also major hosts. The following host species are mentioned in the literature: Acer (e.g. A. negundo, A. truncatum), Alnus, Malus, Morus, Platanus, Pyrus, Robinia, Rosa, Sophora japonica, Ulmus (e.g. U. parvifolia, U. pumila). These trees are either grown in plantations or as city trees. There is no indication that A. glabripennis is a pest of natural forests in China (e.g. in Manchuria).
