PLATE LIX 
Fig. i.—Popoulu variety of cooking banana found infested with the Mediterranean 
fruit fly. Note holes made in peel by the emerging larvae. This fruit was fully ripe 
when found infested; mature fruits still green in color, present on the same bunch, 
were not infested. 
Fig. 2.—Cross section of the Moa variety of cooking banana, showing pulp infested 
by larvae of the Mediterranean fruit fly. Larvae were found infesting the pulp of this 
variety only when the fruits had become mature, though not yellow in color, and when 
the peel had cracked sufficiently to expose the pulp, thus removing Nature’s barrier 
to infestation.
