Damage to Cucumbers by Larvae of Melon Fly. 



Cucumbers affected by melon-fly attack seldom become infested until after the bloom has withered. 

 Nearly all fruits offered for sale in Honolulu markets show various deformities or imperfections 

 caused by oviposition. Frequently fruits maintaining a firm exterior appearance are badly infested 

 within, as were those of figures 1 and 2. (Original.)
