BULLETIN 640, U. S. DEPARTMENT OF AGRICULTURE. 
The great variety of host vegetation which ripens its fruit at 
different seasons leaves no time in Hawaii when fruits are entirely 
out of season. The fact that certain hosts, such as the Chinese 
orange, Surinam cherry, and mock orange, bear several crops a year 
and others, such as specimens of the ball and the winged kamanis and 
the bestill, appear to be seldom entirely free from ripening fruits, 
assure food for the fruit fly the year round. The succession of fruits 
also is increased by the individuality of trees of the same species, or 
even of certain branches of a single tree, which results in a very 
uneven ripening of the fruit. While the data in Table III do not 
indicate the seasonal abundance of host fruits, they have been sum- 
marized from the collections of clean-culture inspections during 1913 
to show the remarkable succession of host fruits ripening in greater 
or less abundance throughout the year in Honolulu. The presence of 
so much ripening fruit, much of it on tall trees such as those illustrated 
in figures 26, 27, and 28, has made it possible for the fruit fly to 
multiply with unprecedented rapidity and thwart artificial remedial 
measures.

campaign collected various fruits infested by the Mediterranean fruit fly. 1
