REPORT OF THE STATE ENTOMOLOGIST 1908 55 
above had been deserted by the aphids and many of them con- 
tained numerous cast skins. Some showed evidence of having 
been invaded by parasites, which latter presumably preyed upon 
the young plant lice. 
Complaint of this insect’s work, accompanied by specimens, was 
received from Mr C. C. Laney, superintendent of parks, Rochester, 
N. Y. This gentleman stated that the galls were more abundant 
on white spruce than upon any other coniferous tree. Serious in- 
juries were reported from Elizabethtown by Mr Seth Sprague 
Terry, who stated that 50 spruce trees, none over 25 feet high, 
have practically all the new growth affected by this insect. Mr 
John Nill sent from Star lake, in the southwestern part of St 



Fic. 18 Spruce gall aphid, destroyed buds; a, one en- 
larged. (Original) 
Lawrence county, badly infested spruce twigs with an inquiry as 
to the cause of the trouble. 
This insect, while rarely causing the death of the trees, fre- 
quently produces serious deformities, because twigs bearing galls 
are very likely to die, thus producing a very unsightly tree. Ex- 
periments conducted by Mr R. A. Cooley showed that thorough 
spraying in April with a whale oil soap solution, 1 pound to 2 
gallons of water, is very effective in checking this insect. A more 
detailed discussion is given in New York State Museum memoir 
<, volume 1, pages 189-91.
