Deformed Pumpkin Fruits Caused by Larwe of the Melon Fly. 



Various deformities of very young pumpkins caused by infestation started before or just after 

 fertilization of the ovary. These fruits persist for a time, due to callouses developing about 

 points of attack, but they never reach a much larger size and are ultimately destroyed by fungi 

 and secondary insect attack. (Original.)
