Deformed Watermelons Resulting from Late Infestation by Larv/e of Melon Fly. 



Often during the cooler months watermelons become infested so late in their development that the 

 larvae can not penetrate the pulp and often die "within the egg chamber. The development of 

 the fruit about these affected areas is arrested and various deformities result, as shown in figures 

 1 and 2. (Original.)
