MEDITERRANEAN FRUIT FLY IN BERMUDA. 



3 



HOST FRUITS IN BERMUDA. 



Col. W. R. Winter, in the bulletin previously mentioned, lists 47 

 fruits subject to attack. To this list for Bermuda should be added 

 the ball kamani (Calopliyllum inophyllum), the prickly pear (Opuntia 

 sp.), and the acordia. While the list of host fruits given is so large 

 that one receives the impression that the fruit fly has an abundance 

 of fruit in which to develop, conditions are quite the opposite in 

 Bermuda. After having carried on a clean-culture campaign against 

 this pest in the Hawaiian Islands, where there exists a very great 

 abundance of many host fruits, the writer was surprised at the scarcity 

 of host fruits in Bermuda. In Table I is recorded the vegetation 

 found growing in portions of the city of Hamilton.

The number of trees and shrubs in Bermuda which bear fruit 

 subject to attack is very small. Out of 9,828 acres of land only 2,636 

 acres were recorded under cultivation in 1901, and this acreage has 

 but slightly increased. The principal products raised for expert, 

 potatoes, onions, arrowroot, lily bulbs, and garden vegetables, except 

 peppers, are not subject to attack. On the uncultivated areas the 

 host fruits are mainly conspicuous by their absence. In such areas
