INTRODUCTORY STATEMENT 
In this, the first number of the third volume of the Insect 
Pest Survey Bulletin, vie are inaugurating a nsw feature. Through 
the generous cooperation of the entomological forces of the Dominion 
of Canada we are able to include a monthly review of the outstanding 
entomological features of the great territory lying north of the 
United States which has so many entomological problems in common 
with the northern States of this Union* 
An Insect Pest Survey of the Dominion of Canada, working along 
similar lines and with the same general purpose as this Survey, has 
tecently been instituted and is under the supervision of Mr« R- C. 
Treherne, Chief of the Division of Field Crop and Garden Insects of 
the Canadian Department of Agricultural 
The appearance of the Annual Summary of insect conditions 
throughout the United States for the season of 1922 will be delayed 
somewhat, as the Survey is attempting to review a much more compre- 
hensive kroup of insects than was reviewed in the first Annual 
Summary* In addition to the larger scope of the summary the mass 
of data being received from the States is constantly increasing- 
During the past winter the distribution records of the Survey 
have been very materially augmented by the extreme generosity of our 
collaborators in three Staled'', who have very kindly loaned us their 
entire file of correspondence record cards, in one case extending 
back to 1888. These cards indicate the name of the insect, the date 
and the place, ani in some cases the crop attacked as referred to 
in each letter received at the Station* These recoris very clearly 
indicate the parts of the State where certain insect pests are most 
frequently attracting the attention of the agricultural population, and 
when similar data are brought to -other over a reasonably large area 
- C the region of optimum conditions for the successful life of a 
givenppest can soon be ascertained.
