MEDITERRANEAN FRUIT FLY IN HAWAII. 25 



2. ACORDIA Sp. 



The friiit of an Acordia with white fleshy pulp was found infested in Bermuda dur- 

 ing December, 1913, by the senior writer. The fruit of the Acordia in Honolulu, 

 which is a different species and more woody, is not infested. 



3. Sour Sop (Anona muricata) . 



The sour sop (Anona muricata) is a fruit which is not ordinarily infested until well 

 grown and is found in the markets in season in perfect condition. Under certain 

 conditions it may become heavily infested. Of 6 overripe fruits, 5 yielded 95, 67, 

 132, 87, and 2 adults. 



4. Sugar Palm (Arenga sacchari/era) . 



A single adult fly was reared from the fruit of the sugar palm (Arenga saccharifera) 

 during May, 1912-, by the Hawaiian Board of Agriculture and Forestry. From a lot 

 of 14 fruits gathered March 17, 1914, only 3 yielded adults. From these 3 fruits, 1,4, 

 and 2 flies were reared. 



5. Breadfruit (Artocarpus incisa) . 



There are no definite records of infestations of the breadfruit (Artocarpus incisa). 

 No adults were reared from 100 very much overripe fruits taken from the ground 

 during August, 1914, and placed over sand in jars. Three larvse were found in one 

 partially decayed fruit, but they were the only ones ever seen by the writers in bread- 

 fruit during a three-year period. 



6. Carambola (Averrhoa carambola). 



The carambola (Averrhoa carambola) becomes infested usually only as it ripens, in 

 spite of the fact that it is fragrant and thin skinned. Many fruits escape infestation 

 even in badly infested districts. Of 40 very ripe fruits collected during September, 

 10 yielded no adults. The other 30 yielded 172 adults, 5 fruits yielding 2, 6, 11, 15, 

 and 20 adults. Only 22 of 62 ripe fruits gathered during August produced adults; 

 from these a total of 289 adults were reared. 



7. Ball Kamani (Calophyllum inophyllum) . 



The ball kamani (Calophyllum inophyllum) is badly infested at times (PI. VI). 

 The adults oviposit very abundantly in the thin, stringy pulp covering the huge 

 seed, as the fruit ripens, but successful larval development often depends largely upon 

 whether the fruit in falling lodges in a place where it remains moist. The fruits on 

 separate trees differ in regard to infestation. On certain trees the pulp may be largely 

 consumed and the larvse well grown when the fruit falls. Generally speaking, the 

 larvse in ball kamani are apt to be underfed, their pupse unusually small, and the 

 adults so depauperized that they may be undeveloped sexually. In a few instances 

 where fruits have fallen in grass on the windward island areas the larvse have developed 

 to normal size. As many as 120 larvse have been reared in one fruit. In April, 1913, 

 7 fruits taken from the ground in Honolulu contained 39, 86, 0, 27, 6, 82, and 115 larvse. 

 From 104 fruits picked from a tree at Waikiki during April, 1913, 927 larvse emerged. 

 Of 20 fruits taken from a second tree 11 yielded no adults; the remaining 9 yielded 

 77 adults, 19 being the largest number from any one fruit. Of 20 fruits of a thick- 

 skinned variety picked from the tree, only 1 yielded adults; a single adult was reared 

 from this fruit. From 1,555 fruits collected during December, 1915, 4,213 larvse were 

 reared. 



8. Peppers (Capsicum annuum var . grossum) . 



Peppers (Capsicum annuum var. grossum) grown in market gardens and generally 

 known as ''bell" or "green sweet" peppers, and used uncooked in salads, are fre- 

 quently, although not generally, infested . Five pounds of peppers gathered August 1
