Plate XIV. 



Regulating Mediterranean Fruit-Fly Conditions. 



As a result of the regulation of the Federal Horticultural Board the unsanitary fruit-fly conditions 

 about banana plantations have been corrected. Fig. 1. — A small Chinese banana"plantation. 

 At present, such guava bushes as are shown, and all other host plants about or in plantation from 

 which fruit is shipped, are cut sufficiently often to prevent fruiting, thus removing the oppor- 

 tunity for fruit-fly larvae emerging from fallen fruit (see insert) to become attached as pupae to 

 wrapping material and be transported to California. Fig. 2. — General surroundings of small 

 banana plantations in Kalihi Valley, Oahu, from which fruit is shipped to California. The 

 fruit fly is thoroughly entrenched on all the mountain slopes. (Original.)
