 June, 1914. 



REPORT OF INVESTIGATION OF THE FRUIT-FLY 

 SITUATION IN THE TERRITORY OF HAWAII 



By Frederick Maskew, Chief Deputy Quarantine OfRcer, San Francisco, Cal. 



In pursuance of instructions received, from Dr. C. L. Marlatt, 

 Assistant Chief of the Bureau of Entomology in charge of citrus fruit 

 investigations, and with the consent of Dr. A. J. Cook, the State Com- 

 missioner of Plorticulture for California, and working in conjunction 

 with both of the foregoing departments, I proceeded to the territory 

 of Hawaii on October 22, 1913, for the purpose of investigating the 

 present status of the Mediterranean fruit-tly situation in all of its 

 several phases, and with special reference to the results and value of 

 the clean culture campaign in force at Honolulu, as viewed from the 

 mainland standpoint, ancl of its bearing upon retarding the possible 

 introduction of the fruit-tly into California, and the United States in 

 general. As a result of this investigation, the following is respect- 

 fully submitted as a report of the findings : 



CLEAN CULTURE CAMPAIGN. 



Organization. 



AVhat is known at Honolulu as the clean culture campaign was 

 originated by the Territorial Board of Agriculture and Forestry under 

 the management of AV. M. Giflfard. Later California made an appro- 

 priation for cooperation in the work, and H. A. Weinland was 

 detailed to represent California in the Islands and took charge of the 

 operations. Finally, the United States Department of Agriculture 

 assumed control, Dr. E. A. Back, as agent, taking charge in September, 

 1912. At the time of my visit the workings of the clean culture cam- 

 paign had been in continuous operation for a period covering approxi- 

 mately thirty months. 



System. 



The plan of operations was admirably conceived at the inception of 

 the work, and great credit is due to Mr. Giffard for the thoroughness 

 with which, under the peculiar circumstances, most of the details were 

 originally provided for. The territory under supervision was divided 

 into eight districts, and these again into twenty-four precincts. A 

 map showing the boundaries of each of the precincts, together with 

 the subdivisions and owners of the same, is on file for reference in 

 the central office now in charge of^Dr. E. A. Back, representing the 

 United States Bureau of Entomology. A remarkably complete system 

 of records of the progression of the work has been kept compiled 

 from the inspectors' daily reports, and these have enabled the manage- 

 ment to keep in intimate touch with the conditions of the food plants
