J. E, Graf, entomologist in charge of field control, was in Wash- 
ington during the month for a conference in regard to future work on the 
sweet-potato weevil and the Mexican bean beetle; especially, in the case 
of the latter insect, with regard to its occurrence in New Mexico. 

C. H. Popenoe, entomologist, is visiting the Estancia Valley of 
New Mexico for a conference with State and collese officials there in re- 
gard to losses incurred by the Vexican bean beetle and the possibility of 
cooperative work in devising means of combating it. Special attentim 
is being given to mechanical means for this purpose.

CEREAL AND FORAGE INSECT INVESTIGATIONS 
W. R. Walton, Entomologist in Charge 
W. R, Walton recently returned from a tour of inspection of the 
westerm areas of corn-borer infestation, He also visited St. Thomas 
and Port Stanley, Ontario, and conferred with the Dominion and Provincial 
entomological authorities regarding conditions and future cooperative plans. 
While at Port Stanley he met a delegation of some forty Ohio agricul- 
tural officers, entomologists, county agents, and farm bureau men, headed by 
Dr. Herbert Osborn, H. A. Gossard, and T. H, Parks, LL. 4H, Worthley, in 
; charge of the corn-borer quarantine and scouting operations, also accompanied 
. the party. The Ohio officials were deeply impressed with the conditions of 
, infestation prevailing in Ontario at present and returned to spread the gos~ 
| pel of control in their State. 
A very distinct lessening in the intensity of the corn-borer infesta- 
tion is apparent in southern Ontario at present, which may be due to the clean- 
. up campaign conducted during the past year by the Deminion and Provincial en- 
| tomologists of Canada and the later planting of corn vhich is largely grown 
for forage purposes in this particular region. No alarming spread or intensi-~ 
| fication of infestation has been noted in the infested areas in the United 
; States this year, The conditions in Ohio and Michigan, except for a slight 
spread into contiguous territory, remain much the sare as those prevailing in 
the fall of 1921.
