THE OUTLOOK IS FAVORABLE 



Whether or not the pest can be eradicated won't be determined for sev- 

 eral months or perhaps years. The answer can come onl} after repeated 

 spraying of host trees, together with a continuing survey. All entomolo- 

 gists cooperating in the work--Mexican, U.S. Department of Agriculture, 

 Arizona, and California — agree that the key to the problem lies in the prog- 

 ress made in northwestern Mexico. If the pest can be eradicated there, it 

 can be eradicated in California. If it cannot be eradicated in northwestern 

 Mexico, there will be no way to prevent infestation of susceptible fruit trees 

 in southern California. Then the problem would be to live with the pest. 



One of the more favorable aspects of the present program is the success- 

 ful pattern of cooperation between Mexico and the United States. Interest of 

 fruit growers, as shown by their willing participation in the enforced spray 

 programs, is another favorable factor. Since attitudes stand next in impor- 

 tance to knowledge of the pestilence, those concerned with the eradication of 

 the fruit fly from the newly infested area feel that the job can be done.
