Host plants that are commonly attacked include wild and cultivated species of Cucurbita. Damage is caused by the larva, which spends its entire life feeding within the plant stems. The first sign of infestation is wilting of the plant during the heat of the day while other plants remain normal in appearance. Fruit may also be infested. Population densities may be determined using sampling methods such as water traps and pheromone traps. Insecticides are commonly applied to prevent young larvae from entering into stems. Chemical control is difficult once the larva has entered the stems. Pollinators should be taken into account before insecticides are applied. Cultural control practices include trap crops and removal of crop residues.
