This list shows that practically all the ordinary useful and edible 

 fruits in Hawaii are infested heavily. Thus peaches can not be grown 

 at present, for they are ruined before they become well grown; Chi- 

 nese oranges (fig. 18), tangerines, figs, loquats (fig. 10, b), rose apples 

 (fig. 11, #),many varieties of mangoes (figs. 8, 24), certain avocados 

 (fig. 13), guavas (fig. 10, a), coffee cherries (fig. 11, b), star apples 

 (fig. 10, c), sapotas, persimmons, apples (fig. 4), pears (fig. 12), 

 plums, nectarines, and quinces — all these are badly infested. On the 

 other hand, a large percentage of the ripening fruits of the tomato, 

 prickly pear, mangosteens, mountain apples, and wampis are free 

 from attack, although certain fruits may be at times heavily infested. 

 When tomatoes are wormy, the melon fly, and not the Mediterra- 

 nean fruit fly, is usually the insect doing the damage. Ordinarily, 

 sweet bell pej>pers are not generally infested, and cotton bolls be- 

 come infested only after they have been damaged by some other 

 insect (figs. 17 and 11, e). 



The pomegranate, breadfruit, eggplant, wi, grape (fig. 25), date, 

 certain seeds of palms, lichee nuts (fig. 11, c), and the Chinese ink- 

 berry are very rarely infested, even in Honolulu. For practical pur- 

 poses they may be said to be immune. Lichee nuts ripening on the 

 tree become infested only when the outer shell breaks, thus exposing 

 the white pulp to attack. 



Hawaiian iruits, nuts, and vegetables not listed are free from 

 attack.
