Nests containing from three to six living larvae of the White Tree Pierid, A porta 

 crataegi L., were intercepted by Federal Inspector Joby A. McCutchin in shipments 

 of fruit and rose stocks arriving at New York from Angers, France. Literature fails 

 to record this insect as being established in the United States; and, to prevent 

 the introduction of this pest, the Chairman of the Federal Horticultural Board has 

 advised the Government Entomologist of France that plant material forwarded under 

 French certificate must be free from the nests of this insect, as well as other pests. 



The White Tree Pierid is reported to be a general feeder in Europe, injuring the 

 foliage of fruit and wild rosaceous plants, as well as shade trees, including oak, 

 mountain ash, willow, etc. It has from time to time been reported as occuring in 

 Russia, Roumania, Sweden, Germany, England, vSpain, France, etc. Records 

 of the Federal Horticultural Board indicate that some sixty-two nests of this insect 

 were intercepted on fruit and rose stocks arriving from France in 1921. The nest of 

 White Tree Pierid is suspended from the infested twig by a silken thread, and this 

 characteristic, as well as its size, will readily distinguish it from the nest of the Brown 

 Tail Moth (see plate 3). 



The Sorrel Cutworm, Acronycta rumicis L., was collected by H. J. Speaker, Ohio 

 State Inspector, January 11, 1922, on Manetti rose stocks arriving from Angers, 

 France. This cutworm has been intercepted on several occasions in years past, 

 and an effort should be made by all inspectors to prevent its entry and establishment 

 in the United States. 



Manetti rose stocks from England and Holland have been found to be infested with 

 Emphytiis cinctns L. by Herbert F. Seifert of Illinois, and the same insect has also 

 been taken by Q. S. Lowry of Massachusetts on stock arriving from France. 



Sweet potatoes from Haiti in ship's stores of a vessel arriving at Philadelphia, were 

 upon inspection, found to be infested with Cylas formicariiis Fab. by Federal Inspector 

 C. A. Davis. These tubers from Barbados were also found infested with Euscepes 

 batatae Waterhouse in a vessel arriving at New York by Federal Inspector E. Kostal. 



It is reported that a shipment of potatoes from Blackfoot, Idaho, which arrived 

 at San Diego, California, was found upon inspection by a Plant Quarantine Inspector 

 of the California Department of Arriculture to contain the Alfalfa Weevil. This 

 was also found in alfalfa hay used for food in two cars containing race horses which 

 were being shipped to Tia Juana. 



In order to prevent the entry and establishment of the Mexican Cotton Boll 

 Weevil in the state of Arizona, the Arizona Commission of Agriculture has authorized 

 the placing of inspectors on the highways entering that state. The timeliness of this 

 action was soon evident, since the Mexican Boll Weevil was found in a small collection 

 of short staple cotton seed which was taken from an auto tourist shortly after the 

 inspectors were placed on the roads. 



On account of the possibility of introducing into the mainland subterranean or 

 soil infesting insects, the Federal Horticultural Board has announced a public hearing 

 to be held in Washington, March 7, for the purpose of considering the advisability 

 of prohibiting the entry of sand, soil, or earth from the territories of Porto Rico and 

 Hawaii. 



Plants for distribution at the Plant Introduction Gardens of the Department of 

 Agriculture located at Savannah, Georgia, Brooksville, and Miami, Florida, were 

 inspected by Messrs. H. L. Sanford and J. A. Stevenson; those at Chico, California 

 were inspected by Messrs. W. S. Fields and T. D. Urbahns; and those at Bellingham 

 Washington, by Mr. A. G. Webb. 



The fourteen-car fumigation house at Nogales, Arizona, which was erected by the 

 Federal Horticultural Board, was completed early in the Fall and put into operation 

 on December 1. At the present time, there are four Federal inspectors located at 

 Nogales. The work at the port is in close cooperation with the Customs and Immi- 

 gration Services, as well as the State Entomologist in Arizona. There were 19,977 

 cars fumigated on the Mexican Border from July 1 to December 31, 1921 inclusive, 

 in contrast with 15,490 fumigated during the preceding fiscal year. 



Professor Davis Lumsden, formerly professor of floriculture at the New Hampshire 

 Agricultural College, and subsequently assistant professor of floriculture at Cornell 

 University, has been appointed as horticulturist for the Federal Horticultural Board, 

 and assigned to the Foreign Plant Quarantine Service.
