Host plant characteristics associated with the distribution pattern of the pine sawfly, Neodiprion xiangyunicus


, : Host plant characteristics associated with the distribution pattern of the pine sawfly, Neodiprion xiangyunicus. Scientia Silvae Sinicae 34(4): 72-80

Distribution patterns of the pine sawfly (Neodiprion xiangyunicus) were investigated in relation to site altitude and forest stand density in China. Based on transect studies, the sawfly was found to be restricted to pure stands of its host (Yunnan pine, Pinus yunnanensis) at specific altitudes. Defoliation and oviposition on Yunnan pine by N. xiangyunicus was confined to a specific altitudinal band (1900-2100 m) within the host range in the area (1650-2100 m).
