The Mediterranean Fruit Fly. 



Fig. 1. — A dense forest growth of the mountain apple {Jambosa malaccensis) near Hilo, which 

 illustrates one of the many strongholds in Hawaii that the fruit fly found favorable to its 

 thorough entrenchment. Fig. 2. — Rose apple trees ( Eugenia jambos). While the fruit of this 

 tree ripens chiefly during the months of March to May, a few may he found beneath trees at 

 any time. Fruits of both the mountain apple and the rose apple are among a class of host 

 fruits that are carelessly taken on board ships by tourists, in whose possession they have 

 been intercepted by the officers of the Federal Horticultural Board at San Francisco.
