early September, on practically all shrubs which they 
commonly infest. 
3. G. Thompson (July): The tent caterpillar adults are 
very abundant in the Willamette Valley. 
APPLE MAGGOT ( Rhagoletis pomonella Walsh) 
T. H. Parks (September 27): The apple maggot was not 
so serious as last year in northern Ohio where it was an 
economic pest in 1928 and 1929. Emergence of flies in 
considerable numbers occurred between July 20 a.nd August 9 
as determined by R. ¥. Dean, who is investigating this 
insect. Two special sprays were advised during this period. 
In the test orchards the apple maggot seems to be well 
under control at this writing, owing apparently both to 
the spraying and to the adverse weather" of the season. 
In a few unsp rayed orchards the insect is still serious. 
No complaints have reached us from localities other than 
northern Ohio. 
JAPANESE BEETLE ( Popillia .iaponica Newm. ) 
U. S. D. A. Press Service (September 18): During the 
present summer, surveys have resulted not only in confirming 
the continuation of the infestation at Providence but in the 
discovery of additional beetles at Newport and Westerly. 
SHOT- HOLE BORER ( Scolytus rugulosus Ratz.) 
T. H. Parks (September 27): Following the serious drought 
of midsummer, shot-hole borers are more numerous than usual 
in peach, cherry, and even apple trees. In Lorain County, 
the beetles were emerging during August from a brush pile 
containing prunings of the orchard and were damaging the 
near-by young apcle trees. 
OYSTER-SHELL SCALE ( Lepidosaphes ulmi L.) 
A. G. P.uggles and assistants (September): The oyster- 
shell scale is quite generally abundant over the southern 
half of the State.

Ohio 
R. H. Pettit (September): The oyster-shell scale is 
moderately abundant in general. 
EUROPEAN RED MITE ( Paratetranychus pilosus C. & F. ) 
T. H. Parks (September 27): The European red mite is not 
a very serious pest in northern Ohio this year. Well sprayed 
orchards are remarkably free from this mite.
