Relation of Flora of Hawaiian Islands to the Mediterranean Fruit Fly. 



Fig. 1.— Men grubbing out a guava scrub which has taken possession of pasture land. Many 

 thousands of acres are thus overrun in Hawaii and furnish excellent breeding grounds for 

 the fruit fly. The ripening fruits fall into the dense grass and the larvae within them develop 

 unmolested by the heat of the sun. Fig. 2.— Thickets of guava bushes often crowd upon 

 the country roads and ripen tons of fruit. This fruit is gathered by pedestrians and autoists 

 and carried to all parts of the islands, thus becoming a medium for the wide dissemination 

 of the pest. (Original.)
