All the cucurbitaceous plants are subject to severe infestation, particularly of the young fruits. Cantaloupes are the most susceptible, since the vines as well as the fruit are attacked badly at all stages of growth, and the fruits do not appear to develop the resistance to attack found among the older watermelons, pump- kins, and squashes. Ordi- narily the cucumber is resistant to attack when very young, although it is rare that cucumbers of- fered for sale in Honolulu do not show some evidence of attack, even w h e n very carefully collected. Cantaloupes and cucum- bers may be used success- fully by the female fly for egg laying up to the time. Fig. 16.—Various deformities of very young pump- kins caused by infestations started before or just after fertilization of the ovary. These fruits per- sist for a time, owing to calluses developing about points of attack, but they never reach a much larger size and are ultimately destroyed by fungi and secondary attack.
