In the codling moth work at the Yakima field laboratory during the 
years 1922 to 1928, inclusive, 180 laboratory tests of ovicides have been 
made , using a total of more than 50,000 codling moth eggs. In the same 
period 900 laboratory tests of larvicides have been made, using 4,500 
apples and 45,000 hatched larvae. 
Dr. A. L. Quaintance attended the Fourth International Congress 
of Entomology, at Ithaca, N. Y., and read E. J. Newcomer's paper on 
"Codling Moth Conditions in the Northwest," Mr. Newcomer not being able 
to be present. 
Dr. Lon A. Hawkins, Physiologist, of the Bureau of Plant Industry, 
visited the field laboratory at Yakima, Wash., August 10. A. Lloyd 
Ryall, Junior Pomologist, working under the direction of Dr. Hawkins, is 
quartered at the Yakima field laboratory for cooperative work in connection 
with the problem of spray residues. 
B. E. Montgomery, who has been serving as Field Assistant at the 
field laboratory at Vincennes, Ind., during the summer, resigned August 
ei. He has accepted a graduate assistanship at the Iowa State Agricultural 
College, at Ames, and is to work there for his doctorate. 
Dr. B. A. Porter, of the Vincennes, Ind., field laboratory, at-— 
tended the International Congress of Entomology, held at Ithaca, N. Y., 
August 12 to 18, and presented a paper discussing the problem of the 
codling moth, as it exists in America at the present time. 
j Dr. B. A. Porter also attended the summer meeting of the Indiana 
State Horticultural Society at Evansville, Ind., August 2, and the meeting 
of the Kentucky State Horticultural Society at Henderson, Ky., August 3. 
At the latter meeting the oriental peach moth, which has recently ap- 
peared in southern Indiana and western Kentucky, was informally discussed. 
Contributions from the Japanese Beetle Laboratory 
On August 14 Loren B. Smith presented a paper on the Japanese 
beetle at the meeting of the Fourth International Congress of Entomology 
at Ithaca, N. Y. 
C. H. Ballou, of the Japanese Beetle Laboratory, served as official 
Spanish interpreter at the Fourth International Congress of Entomology. 
Centeter cinerea Aldrich, the introduced tachinid parasite of the 
adult Japanese beetle, was released in large numbers during July and 
August at Bridgeport, Conn., Harrisburg, Pa., and Noble, Pa. Following 
_ the release of the flies many beetles were recovered upon which eggs had 
been deposited. 
The colony of the Japanese wasp Tiphia popilliavora Rohwer, estab- 
lished near Riverton, N. J., has more than maintained its vigorous condi- 
tion. During August sufficient adults were present to permit the release
