【Aim】 The objective of this study was to investigate the impact of cucurbit family and Solanaceae on the growth, development, and reproduction of Zeugodacus tau. 【Method】 To construct a two-sex life table of Z. tau on Cucurbita moschata, Cucumis sativus, Benincasa hispida, and Solanum lycopersicum and assess the adaptability of Z. tau to these four host plants. 【Result】 The pre-adult survival rate (87.96%) and fecundity (361.26 eggs·female^-1) of Z. tau fed on C. moschata were significantly higher than those fed on C. sativus (80.00% and 288.34 eggs·female^-1, respectively), B. hispida (72.03% and 84.80 eggs·female^-1, respectively), and S. lycopersicum (69.69% and 76.55 eggs·female^-1, respectively). Moreover, the intrinsic growth rate (0.10) and net reproductive rate (90.63) of Z. tau on C. moschata were significantly higher than those on C. sativus (0.08 and 74.37, respectively), B. hispida (0.07 and 35.62, respectively), and S. lycopersicum (0.07 and 26.03, respectively). 【Conclusion】 Z. tau was able to complete its generation cycle in all four host fruits. However, C. sativus was the most suitable host for Z. tau.
