New Records of Anastrepha grandis (Diptera, Tephritidae) and Neosilba zadolicha (Diptera, Lonchaeidae) in Cucurbitaceae Species in Brazil

This is the first report of natural infestation of fruit flies Anastrepha grandis Macquart (Tephritidae) and Neosilba zadolicha McAlpine & Steyskal on bottle gourd [Lagenaria siceraria (Mol.) Standl.] and mogango (Cucurbita pepo L.). Six cultivars of Cucurbitaceae were susceptible to infestation by A. grandis and their larvae reach pupation and adult emergence. The average weight of pupae was similar between zucchini, squash 'Menina Brasileira' and mogango. Orange pumpkin and 'Atlas' butternut showed the lowest average weight of pupae and their sampled pupae showed similarity of weight by Morisita index. The pupal viability ranged from 57.5% to 95.8%.
