Interpretive Summary: Scarlet-fruited gourd is a climbing vine that can cover trees, fences, power lines, and buildings. It has invaded Hawaii, where it has been declared a noxious weed. Besides being a pest, its fruit serves as a host for the melon fruit fly that is a serious pest of cucurbits and a potential invader of the mainland USA. We sampled scarlet-fruited gourd for two years sto determined its contribution to melon fly populations. We reared 500 - 800 flies from each kilogram of fruit, demonstrating that this weed is an important contributor to melon fly populations. Only 5-6% of the melon flies were parasitized during the two-year study. This weed should be considered in any pest management program to control melon flies.
