BUREAU OF ENTOMOLOGY AND PLANT QUARANTINE

Luke County, Utah, from the regulated area. Mosaic was found in 
Alfalfa and* Woods Counties in Oklahoma. In the spring of 1944 the 
annual inspection was made in infected areas of all nurseries and their 
1-mile environs. The number of nurseries ineligible for certification 
has decreased annually, and there has been no record of spread of 
these diseases through nursery-stock shipments in the last 6 years. 
The apparent eradication, since 1936, of the phony disease from 6 
entire States and a 98-percent reduction' in 8 others made it possible 
in 1943 to direct greater attention to the heavily infected Slates of 
Alabama and Georgia, where 48.790 phony trees (68 percent less than 
in 1936) were found and destroyed. 
With the cooperation of Mexican pest -control officials, inspection 
was made in the Juarez Valley, Chihuahua, and 947 mosaic trees 
were found on 170 of the 192 properties inspected. 
SURVEY FOR ORIENTAL FRUIT MOTH IN NINE WESTERN STATES 
The survey in the spring and summer of 1943 for the oriental fruit 
moth resulted in the discovery of infestations in parts of 62 counties 
extending from northeastern Texas through parts of Oklahoma, east- 
ern and east-central Kansas, southeastern Nebraska, and southern 
Iowa. Following the twig inspections, trapping operations for adult 
moths resulted in locating an infestation in an additional county in 
west-central Kansas in September. In the spring of 1944 a more in- 
tensive inspection and trapping program was instituted, and was 
under way, at the close of the year, in the more important fruit areas 
of Arizona, Colorado, Idaho, Nevada, New Mexico. Oregon, Utah, 
Washington, and the El Paso Valley of Texas. The moth has not 
previously been found in these areas. The States have rendered as- 
sistance in both years. 
NO TRACE OF CITRUS CANKER FOUND 
Federal-State inspection for citrus canker was conducted from Octo- 
ber 1943 to March 1944 in 35 Texas counties, including vicinities of 44 
nurseries, without finding the disease. Formerly infected areas in 
Brazoria, Galveston, and Harris Counties and the town of Hamshire 
in Jefferson County were intensively inspected for any vestige of this 
highly infectious bacterial disease. Particular attention was given to 
old hedges of trifoliate-orange at Navasota, where citrus canker was 
last found in this country in 1943. As no Federal funds were made 
available for the work in 1945, Bureau participation in this activity 
was discontinued J une 30, 1944. 
GYPSY AND BROWN-TAIL MOTHS CONTROL 
Gypsy moths are known to be present only in a relatively small part 
of the Northeastern States. The object of control is to protect our 
forests by eradicating this destructive insect from the isolated area 
of infestation in northeastern Pennsylvania and by preventing its 
spread from the infested area in eastern New York and in New 
England. The program is sufficiently flexible to allow prompt modi- 
fication whenever developments of research or control procedure in-
