W. H. Larrimer, in Charge 
C. M. Packard, in charge of the West Lafayette, Ind., field lab- 
Oratory, made a trip to Carlisle, Pa., and to Washington, D. C., on May 
26 and 29 to discuss investigations of the Hessian fly. 
H. A. Jaynes has made what is perhaps the first airplane ship- 
ment of beneficial insects from South, America to North America. On 
Mayeo he sent by airplane from Trujillo, Peru, 1,075 adults of Ipobra— 
con rimac, 2 hymenopterous parasite of the sugarcane moth borer. The 
Shipment arrived at Miami, Fla., on May i1, and, in cooperation with 
E. R..Sasscer, Entomologist in Charge of Foreign Plant quarantines, 
and J. V. Gist, Collaborator with the Plant Quarantine and Control Ad— 
Ministration of the State Plant Board of Florida, was then sent by ex- 
press to New Orleans, arriving there on May 13. Three hundred and twenty-— 
seven of the wasps were alive and in good condition. The total trip 
was less than 6 days, whereas by ship and train it would have required 
about 22 days. The percentage of survival was better by airplane, al- 
though the parasites were not kept at low temperatures, as they are when 
sent in the ordinary way. 
Dr. F. W. Poos, Entomologist in charge of the field laboratory at 
Arlington Farm, Va., and M. V. Anthony, Field Assistant, of that labor- 
atory, made a trip to Columbus, Ohio, on May 26. Mr. Anthony is being 
temporarily stationed at Columbus to carry on work on the control of 
alfalfa yellows. He will work in cooperation with Dr. C. J. Willard, of 
the department of farm crops of the Columbus College of Agriculture. 
Dr. W. H. Larrimer spent the period May 18 to 23 at the Toledo, 
Ohio, and Monroe, Mich., field laboratories, discussing corn—borer con- 
trol with specialists in charge of that work.
