W. H. Larrimer, in Charge 
A general conference on the European corn borer was held at Toledo, 
Ohio, September 24 and 25. The meeting this year was in many ways more 
comprehensive and instructive than such meetings have been in the past, 
although rainy weather interfered considerably with the original plans. 
Information was released on the status of the borer for the present 
season, including spread and abundance. Detailed reports were given on 
the various phases of research. There was the usual large attendance, 
representing farmers, business and banking interests, manufacturers of 
agricultural machinery, and State and Federal officials. A complete 
report of the conference will be available later. 
W. B. Cartwright has returned from the Orient, where he spent the 
last two and one-half years collecting and forwarding to the United 
States parasites of the European corn borer. It will be remembered 
that C. A. Clark reported to Mr. Cartwright in Japan in September, 1929, 
in order that he might become familiar with the parasite work before 
taking charge of the work initiated by Mr. Cartwright. After clearing 
up several questions regarding the parasite work, Mr. Cartwright will 
resume charge of the field laboratory at Sacramento, Calif.
