INTRODUCTORY STATEMENT 
In presenting the initial number of the second volume of 
the Bulletin, the Insect Pest Survey wishes formally to thank 
its Collaborators for the very sincere and painstaking efforts 
they have made in obtaining and transmitting information relative- 
to insect conditions in their respective territories. It wishes, 
also , to express its appreciation of the commendations they have 
made of the Survey's work, both in correspondence and in the 
resolutions adopted at the Annual Meeting of the American 
Association of Economic Entomologists held at TGronto. 
The coming season's reports rromise to be much more complete 
than those of last year. The Collaborators in most cases have 
organized definitely for Survey work, some with a specialforce 
of assistants, and others by a cooperative arrangement with the 
Extension Service of the State, thus utilising the County Agent 
force, Ehe scope of the Survey's work is much better appreciated 
than when the work was inaugurated, and the Collaborators are 
reporting all notes on insect conditions at the present time, 
realizing that what might seem a trivial and normal condition rcay 
prove of inestimable value, when associated with similar reports 
from several other Collaborators. 
One of the greatest difficulties experienced in summarizing 
the data received is in interpreting the comparative terms used 
in describing the extent of destructiveness of a pest. This is 
no fault of the reports but serves to accentuate the lack of 
definite standards in this field. The nearest approach to these 
definite standards is the percentage of infestation and percentage 
of damage figures that are being used in some of the major pest 
surveys. 
The Annual Summary of the insect conditions for 1921 is now 
about ready for publication. The scope of this work was necessarily 
modified from that set forth in the Introductory statement of 
Volume 1, The entire field could not be covered with the limited 
force at command, so nineteen of the more important and interesting 
pests were selected and reviewed.
