MISCELLANEOUS ITEMS 
DUTCH ELM DISEASE CONFERENCE OCTOBER 26 
(Press notice) 
October 14, 1933. 
A conference to discuss Dutch elm disease problems and plans has been 
called by Avery S. Hoyt, Acting Chief of the Bureau of Plant Quarantine, to 
be held in the auditorium of the Interior Department Building. Eighteenth and 
F Streets NW., at 10 a.m., Thursday, October 26. 
Mr. Hoyt explains that the Bureau of Plant Industry of the Department, in 
cooperation with the States concerned, is engaged in a vigorous attempt to 
suppress an outbreak of the disease centering in the metropolitan districts 
around Newark and New York City. The outbreak has aroused wide interest, 
and those attending conferences on other insects and plant disease subjects 
called for October 24 and 25 will have a chance to review the Dutch elm disease 
problem. At the conference representatives of the Bureau of Plant Industry 
will present information as to the distribution and economic importance of the 
disease, and members of the Bureau of Entomology staff will discuss the insect 
pests, which are the only carriers thus far known. 
By October 3 approximately 500 trees infected with this disease had been 
reported in northern New Jersey, some 27 infected trees in southeastern New 
York, 1 in Connecticut, and 1 this year in Ohio, in addition to 7 found in Ohio 
in 1930 and 1931. 
The disease apparently is being spread locally by a bark 'beetle known sci- 
entifically as Scolytus multistriatus. That beetle reached this country a con- 
siderable number of years ago and has been found thus far to be established 
over a general area extending from the vicinity of Philadelphia, Pa., to eastern 
Massachusetts, said Mr. Hoyt in reviewing the situation. 
The evidence indicates that the disease reached this country by the importa- 
tion of infected logs for use in veneer plants. A closely related insect which 
is more commonly connected with the spread of the disease in Europe lias also 
been found in these logs but is not known to be established in this country. 
Restrictions on the further importation of such logs have been given considera- 
tion and the Bureau of Plant Quarantine will soon announce action which will 
be taken with respect to such importations. 
The conference called for October 26 follows a general conference which was 
announced sometime ago for October 25 to consider modifications in the restric- 
tions governing the importation of nursery stock into the United States. On 
October 24 a hearing will be held to give consideration to the extension of the 
Japanese beetle quarantine. The Bureau has arranged this series of confer- 
ences so that those interested in more than one of those three subjects can 
attend the discussions of all three without additional travel.
