fume liquid at the rate of thirty-six teaspoonsful to four gallons of 
water was applied and found only to stupefy, but not to kill the adults. 
On further inquiries at the Indiana State Entomologist’s office we 
were informed that the strawberry root-worm was first recorded as a 
greenhouse pest in that state, November 8, 1916. The specimens of 
the insect and the report of the injury came from a florist at Cumber¬ 
land. The Richmond infestation evidently started in 1915, according 
to the following information: 
It was ascertained from the Richmond florist that this insect prob¬ 
ably found its way into his greenhouses, three years before, in the larval 
stage in sod which was brought into the houses at that time. This 
sod was taken from soil in close proximity to their establishment on 
which large patches of wild strawberry plants were growing. These 
wild strawberry plants are also abundant at present on the right-of-way 
of the Pennsylvania railroad which runs directly by their infested 
houses. 
A subsequent report indicated that it has been found attacking 
garden grown roses in the same vicinity. 
In attempting to establish the possible origin of the infestation in 
Alexandria, records show that Mr. A. D. Borden had reported this in¬ 
sect as attacking roses in these same houses three years before. Recent 
evidence discloses that the soil in which the roses are now growing has 
been in these benches since then. We are, therefore, led to believe 
that the present occurrence dates back to that time. 
Early in November the writers collected specimens of the strawberry 
root-worm in the rose house of the United States Botanical Garden at 
Washington, D. C., where they were doing serious injury. Since then, 
reports of its occurrence on roses have been received from Summit, 
N. J. In addition to this, E. N. Cory 1 in 1916, of Maryland Experi¬ 
ment Station, had occasion to work with it on roses in a florist’s estab¬ 
lishment at Baltimore. 
A circular letter sent to all State Entomologists as well as other 
entomological workers has thus far failed to give us further records of 
its occurrence on roses, except the one record from Summit, N. J. 
This information was received from Dr. Peterson, the Assistant State 
Entomologist, substantiated by a report from the florist whose roses 
were infested. 
Further information gathered from replies received indicates that it 
has been known to injure mountain ash, crab apple, and occasionally 
is reported as doing considerable damage in apple orchards. While 
primarily a pest of strawberries, its injuries to the above hosts are only 
occasionally of great consequence.
