Bulletin
R. Neil Chrystal
1926
This Bulletin provides information on the life-cycle of the silver fir chermes in Britain, as well as information on the relationship between the insect and its host tree, the silver fir, to ascertain how far the chermes was responsible for the death of the tree. The Bulletin also presents certain information collected by the author during a visit to Denmark, made in June, 1924, for the purpose of studying the silver fir plantations there with reference to the chermes. These results are correlated here with an account of the silver firs in Britain, based upon information currently available.
