The present study was conducted for the evaluation of different pumpkin cultivars against Red Pumpkin Beetle Aulacophora foveicollis L. (Chrysomelidae: Coleoptera) at University Research Farm Koont, during 2016. The data regarding number of eggs, larvae and adult population on Bottle Gourd Lattu and Bottle Gourd varieties with 0.26 and 0.23 number of eggs per leaf while 0.31 and 0.22 larvae population per leaf and maximum population of adults with 0.26 and 0.18 per leaf were recorded respectively. The minimum population of eggs, larvae and adult were recorded on Round Gourd Hybrid-F1 with 0.08, 0.06 and 0.05 per leaf respectively. According to physico-morphic characters the length and girth of Bottle Gourd Lattu and Bottle Gourd varieties were maximum with (0.26 and 0.18 cm length of plant) and (20.97 and 20.67 mm girth of plant) and minimum vines length and girth with 0.18 cm length of plant and 20.72 mm girth of plant were recorded on Round Gourd Hybrid-F1. The leaf infestation of Bottle Gourd and Bottle Gourd Lattu were maximum with 33.33 and 33.21 percent respectively while minimum infestation was recorded on Round Gourd Hybrid-F1 i.e 24.25 percent. Flower infestation of Bottle Gourd and Bottle Gourd Lattu were higher with 22.81 and 22.76 percent and minimum on Round Gourd Hybrid-F1 with 14.83 percent. Maximum yield was observed on Round Gourd Hybrid-F1 with 17.11 kg while the Bottle Gourd Lattu and Bottle Gourd had low yield 10.58, 10.58 kg respectively.
