from sonora to Carlsbad he is to interview stockmen regarding their problem 
with insects affecting livestock. 
Arrangements are being made at the tobacco insect laboratory at Clarks- 
ville, Tenn., to detail two men, during May and part of June, for investiga- 
tions of tobacco wireworms at Lexington, Ky. Their work will consist of tests 
of remedies and recording of data upon damage and distribution. 
An important conference was held at Tucson, Ariz., on April 10 to de- 
termine the best procedure to follow in view of the recent discovery of the 
Thurberia weevil in cotton grown near Tucson. It was attended by the Arizona 
Quarantine Commission, representatives of cotton planting interests in Arizona, 
and by W. D. Hunter, R. E. McDonald of the State department of agriculture, as 
well as A. W. Morrill and W. D. Pierce. ‘The State commission decided, on the 
advice of W. D. Hunter and R. &. McDonald, to establish a noncotton zone ex- 
tending about 30 miles from the Santa Catalina Mountains. 
Dr. W. R. Dodson, Chairman of the Cotton Council of the Association of 
southern Agricultural Workers, called a meeting at Atlenta, Ga., on April 14, 
for considering plans to use as nearly as possible a uniform system in planning 
and recording boll weevil experiments during the coming season. Such a course 
is highly desirable on account of the difficulty which has been experienced 
heretofore in comparing results obtained in experiments performed according to 
diverse plans. Entomologists from practically all of the Southern States ex- 
cept North Carolina and Florida were present. B. R. Coad represented the Bu- 
reau of Entomology. <A definite program was worked out and adopted. 
FOREST INSECT INVESTIGATIONS 
F. C. Craighead, Entomologist in Charge 
Dr. Craighead spent several days during the last week in April in the 
vicinity of Covington, Va., investigating the southern pine beetle situation. 
It was found that this epidemic has developed into unusual proportions in this 
region and that at least 25 per cent of the pine stands have been destroyed. 
Only the finer and better older stands have been attacked while in no case was 
the beetle found in any pines under 30 years of age. Paper and pulp companies 
drawing their supplies from this region will be seriously affected during the 
next few years through a shortage in material resulting from the work of this 
beetle. Considerable effort is being made in salvaging the killed timber al- 
though the greater portion of it will deteriorate too rapidly to be utilized. 
Dr. Snyder reports that damage to the woodwork of buildings and their 
contents by termites or white ants has continued to be serious throughout the 
United States and to date from July 1, 1923, 94 cases have been reported to the 
Bureau, which is probably only a small proportion of the actual number of cases 
that have occurred. The Bureau is advocating slight modifications of the
