Abstract

Two hybrid cucurbits were produced that combined the genetic production of cucurbitacins as found in the wild bitter gourds, Cucurbita andreana Naud and C. texana Gray, with the high fruit yields characteristic of the domesticated cultivars of C. maxima Duchesne and C. pepo L. Both the C. andreana × C. maxima and C. texana × C. pepo hybrids produced relatively high yields of fruit with high cucurbitacin content. Both hybrids showed promise as attractants for population estimation of corn rootworm beetles (Diabrotica undecimpunctata howardi Barber and D. virgifera LeConte) or for use in poisoned baits using methomyl or trichlorfon with the bitter cut fruits or fruit homogenates.
