Bulletin
Issac William Varty
1956
Insects of the genus Adelges have long been recognised as economically important pests of the valuable timber-producing silver fir trees that comprise the genus Abies. In fact the planting of the common European silver fir, Abies alba, has had to be greatly restricted in Britain because of the depredations of these insects. This Bulletin gives the results of Dr. Varty’s intensive studies of the Adelges insects in relation to forestry, which were carried out in Scotland under the auspices of the Department of Forestry of Aberdeen University. It replaces Bulletin No. 7 - The Silver Fir Chermes.
