October, '17] CURRENT NOTES 511 



According to the Experiment Station Record, the staff of the Department of En- 

 tomology at the Kansas College and Station and Federal entomologists are being 

 organized to control the Hessian fly in counties where it promises to injure the wheat 

 crop in 1918. The early and thorough plowing under of wheat stubble, elimination 

 of volunteer wheat in fields later, and planting after the fly-free date are the recom- 

 mendations being made. These practices, however, are advisable in order to obtain 

 maximum yields, regardless of Hessian fly infestation. 



Mr. Harold Morrison, Bm-eau of Entomology, who recently made a trip of ex- 

 ploration to the Virgin Islands and the West Indies, has completed his work in the 

 Virgin Islands and Porto Rico and is probably now in Santo Domingo. Some very 

 interesting commimications have been received from him in relation to this work and 

 good deal of valuable material. Valuable material is also being received from the 

 collaborators appointed in Central and South American countries in connection with 

 the study of the fruit-flies and other insect pests of such countries. 



Mr. Jacob Kotinsky, Bureau of Entomology, spent June 27 in Philadelphia where, 

 with the assistance of F. M. Trimble of the Pennsylvania State Zoological Service and 

 the Federal Horticultural Board, elm-leaf beetle, Galerucella luteola Mull., eggs were 

 located and a colony of parasites received by Dr. Howard from M. F. Picard of the 

 ficole Nationale d' Agriculture, MontpeUer, France, was released. Small colonies of 

 this parasite were also released in Ithaca, N. Y., by Professor Robert Matheson and 

 by Mr. Kotinsky in Washington, D. C. No prediction as to results can be made as 

 yet. 



Mr. H. F. Dietz, Bureau of Entomology, is now in New York investigating the 

 fmnigation of orchids. The experimental work conducted by Messrs. Sasscer and 

 Dietz with orchids has demonstrated that orchids can be safely fumigated with one 

 ounce of sodium cyanid in a 20-inch vacuum at an exposure of 40 minutes without 

 injury, provided reasonably healthy plants are used; in fact, with healthy plants as 

 strong a dose as four ounces of cyanid has been used under the same conditions without 

 killing the plants. A month after treatment the plants so treated are making new 

 growth, both roots and buds. 



C. W. Howard, Associate Professor of Entomology and Parasitology, University 

 of Minnesota, has accepted the position of Professor of Biology in Canton Christian 

 College, Canton, China. Professor Howard will sail from San Francisco the middle 

 of October, visiting the Hawaiian Islands, Manila and Japan enroute. Canton 

 Christian College is the only institution of collegiate rank in South China. The 

 rapid growth of the agricultural and medical departments has made necessary the 

 organization of a department of biology. All commimications should be addressed 

 to Canton Christian College, Honglok, Canton, China. 



The following transfers in the Bureau of Entomology have recently been announced : 

 W. T. Emery, Charlottesville, Va., to Wellington, Kans. ; G. A. Runner to Sandusky, 

 Ohio; J. S. Wade, WeUington, Kans., to Washington, D. C; Dwight Isely, North 

 East, Pa., to Bentonville, Ark.; J. J. Culver, Fort Valley, Ga., to Monticello, Fla.; 

 A. I. Fabis, Monticello, Fla., to Brownwood, Tex.; D. J. Caffrey, Tempe, Ariz., to 

 Hagerstown, Md., in charge of the laboratory; J. A. Hyslop, formerly in charge of 

 the Hagerstown, Md., field laboratory, to Bureau Extension work; G. W. Barber, 

 WelUngton, Kans., to Hagerstown, Md.; H. O. Marsh, Rocky Ford, Colo., to New 

 Jersey (temporarily); F. B. Milliken and A. B. Duckett, formerly truck crop insect 

 investigations, to stored product insect investigations.
