Abstract As is traditionally recognized (e.g. by Gauld & Bolton, 1988; Naumann, 1991; Smith, 1993), the suborder Symphyta (the sawflies and woodwasps) is a para phyletic assemblage comprising the structurally more primitive Hymenoptera. Symphytan adults share a number of primitive (plesiomorphic) character states: their abdomen is

The Canadian Entomologist, 1955
Although a virus disease of the larch sawfly, Pristiphora erichsonii (Htg.), has not been discovered, polyhedrosis viruses of several other Tenthredinids are known. They have been used to control infestations of two introduced species: the European spruce sawfly, Diprion hercyniae (Htg.), (Bird, 1954) and the European pine sawfly, Neodiprion sertifer ...
