A meeting of entomologists, agronomists, railroad agricultural agents, and others 
interested in insect control in the southwestern winter wheat area, was held at Kansas 
City, Mo., May 24. A uniform plan for chinch bug control in the states of Iowa, 
Nebraska, Kansas, Missouri and Oklahoma was adopted and a committee was ap¬ 
pointed to draft a similar program for Hessian fly control. Entomologists in attend¬ 
ance were: M. H. Swenk, H. B. Hungerford, J. R. Horton, C. J. Drake, I. L. Ressler, 
E. G. Kelly, J. W. McColloch, Otis Wade, L. Haseman, K. C. Sullivan, C. E. San¬ 
born, A. F. Satterthwait, Wm. Moore and V. I. Safro. 
During the first part of May a oreliminary examination of the proposed forest 
insect control project in the Missoula National Forest was made by J. C. Evenden 
and Elers Koch, Assistant District Forester, District 1. This project calls for a line 
of defense against the heavy epidemic of the mountain pine beetle, which threatens 
the valuable lodge-pole pine stands of the Deerlodge and southern Missoula National 
Forests. At the present time H. J. Rust, Entomological Ranger of this station, is 
marking the trees that are to be treated, and it is expected that control work will be 
started by May 22. 
Dr. S. A. Graham, of the Lake States Forest Experiment Station, and Dr. S. B. 
Fracker, state entomologist of Wisconsin, made a survey through the jack pine 
growing areas of Wisconsin in June looking up insect infestations. It was found that 
the jack pine sawfly, which is locally injurious in certain other pine areas of the
