CEREAL AND FORAGE INSECT INVESTIGATIONS 
W. H. Larrimer, in Charge 
About the middle of June Prof. Chas. J. Sorenson, of the Utah Agri- 
cultural College, at Logan, visited the field laboratory at Tempe, Ariz., 
and conferred with the men there regarding investigations of the clover 
and alfalfa seed chalcis fly which are being carried on in cooperation with 
the State of Utah. 
W. J. Phillips, in charge of the field laboratory at Charlottesville, 
Va., Spent June 27 in the Washington office. 
W. R,. Walton left Washington May 3 for a tour of inspection of the 
southern and southwestern field laboratories of the division. He visited 
New Orleans, Houma, and Crowley, La., and Beaumont and San Antonio, Tex. 
At Albuquerque, N. M., he was joined by V. L. Wildermuth and J. C. Franken-—- 
feld, of the field laboratory at Tempe, Ariz. The party visited the range-— 
caterpillar territory in northeastern New Mexico, where the eggs of the 
insect were found to be present in extreme numbers. After completing plans 
for the summer work there, an inspection was made of the summer cattle 
ranges at the higher elevations. Messrs. Wildermuth and Walton also visited 
several parts of New Mexico and Arizona, to examine and discuss the infesta-— 
tion by the southwestern corn borer. Among the regions examined was the 
area lying between Phoenix and Tucson, Ariz., and extending to the Mexican 
border. E. G. Davis, of the field laboratory at Tempe, assisted in this 
survey. Mr. Walton returned to Washington June le. 
Temporary appointments were given in June to Adam M. Celaya, at 
Tempe, Ariz., Clyde B. Conger, Sacramento, Calif., James B. Gahan, Webster 
Groves, Mo., and Richard A. Gaskins, Richmond, Va. 
Carl Heinrich, specialist in Lepidoptera of the Taxonomic Unit of 
the Bureau, who left Washington on April 9 to investigate the occurrence of 
the European corn borer in Guatemala, as reported by Cosmio Riccio, returned 
June 19 and submitted his report. Mr. Heinrich was fortunate enough to be 
able to examine corn growing in the identical field in the neighborhood of 
Antigua where Pyrausta nubilalis Hibn. was reported. No European corn borer 
was found, but there was an injurious abundance of the Central American 
corn borer, Diatraea lineolata Walker. Adult moths were reared from this 
material and accurately determined as this species. 
L. H. Worthley, in charge of corn-borer control, was in Washington 
on June 27 to consult with various officials regarding plans for the annual 
survey of infestation by the European corn borer.
