1984
Document Number: 386005
This report on forestry in the United Kingdom includes a note (p. 22) to the effect that no plantations had to be treated for the control of the pine beauty moth [Panolis flammea (Denis & Schiff.)] in 1982 and that control measures would probably be unnecessary in 1983, and a note (p. 32) on the possible use of the predator Rhizophagus grandis Gylh. for the biological control of Dendroctonus micans (Kug.), a scolytid that was first found in Britain in August 1982. The damage caused to trees by D. micans is illustrated in colour (pl. 2).
