Spine gourd is nutritious cucurbits with medicinal properties and due to these specialties in this potential vegetable crop it has high demand in local and national market. The objective of present investigation was to screen different crosses of spine gourd against fruit fly (Bactrocera cucurbitae). The experimental material comprised of different 21 crosses of the spine gourd. The result revealed that none of the cross showed immune reaction against fruit fly. Whereas, crosses of AMBIKA13-5 x IK-1 and AMBIKA13-6 x IK-1 were found highly resistance, crosses RMDSG-4 x IK-1, AMBIKA13-6 x AJSG-2 and NDM-2 x IK-1 showed resistance and crosses AJSG-1 x CK-2, RMDSG-3 x IK-1, RMDSG-3 x AJSG-2 and NDM-5 x AJSG-2 were found resistance towards fruit fly. These crosses may be used for the development of resistant cultivar as well as identification of resistance gene for fruit fly in spine gourd.
