. Bulletin of the Department of Agriculture. Agriculture. THE MEDITERRANEAN FEUIT FLY. 25 avocados, no commercial orchards exist in Hawaii. Still there is hardly a family, unless it be in the business section of Honolulu, that does not grow a number of fruit trees, such as oranges, lemons, papayas, peaches, avocados, limes, grapefruit, guavas, bananas, man- goes, etc., that bear prodigally under normal Hawaiian cultural con- ditions, and, until the advent of the fruit fly in 1910, formed a most welcome addition to the food supply. Much of the native-grown fruit that is sold in the local market is grown on trees scattered here and there in dooryards and is in excess of what the owner needs. Practi- cally no one depends on growing fruit for his living. No devel- oped fruit industry exists such as one finds on the main- land, and no moneyed interest concerns it- self with steps for fruit-fly eradication. In other words, there are no impelling in- centives to solidify public opinion for the consistent and coop- erative use of artificial remedial measures that could be made effective if their ap- plication would yield returns warranting the expenditure. The situation also is made more difficult by reason of the large amount of vegetation, bearing fruits of little or no value to man, that grows throughout the islands and that can not be eradicated without the expenditure of prohibitive sums of money. But this great abundance of dooryard and wild host vegetation has had such a vital part in the undoing of artificial control measures and in the success of parasite introductions that it is worthy of fur- ther attention. Aided by a favorable climate, it has made of Hawaii a fruit-fly paradise that is not duplicated elsewhere on the Fig. 24.—Improved mango sectioned to show havoc caused by maggots of Mediterranean fruit fly.
