In order to develop integrated management approaches for Pectinophora gossypiella, basic studies are crucial. The two-sex life table is the most important tool for describing the fitness and population parameters of both sexes (male and female) of an insect, while the traditional life table only explains the female sex of an insect. However, no study has reported on the biology of P. gossypiella using two-sex life table tools. Therefore, this study explains the rearing dynamics of P. gossypiella on a cotton seed-based artificial diet and a natural diet (mature cotton bolls). According to the results, the oviposition period of P. gossypiella was recorded to be longer on the artificial diet (9.07 ± 0.24) compared to the natural diet (7.40 ± 0.11). The total fecundity of P. gossypiella was greater on the artificial diet (125.94 ± 3.06) in comparison to the natural diet (60.37 ± 1.10). The population parameters, including intrinsic rate of increase, finite rate of increase, gross reproductive rate, and net reproductive rate of P. gossypiella were highest on the artificial diet in comparison to the natural diet. This study concluded that the cotton seed-based artificial diet was most suitable for the rearing of P. gossypiella. In the future, P. gossypiella may be studied in depth in light of the findings in this study.
为了制定对棉铃象甲的综合管理方法，基础研究至关重要。两性生命表是描述昆虫（雄性和雌性）两性适应度和种群参数的最重要工具，而传统生命表仅解释昆虫的雌性。然而，尚无研究使用两性生命表工具来描述棉铃象甲的生物学。因此，本研究解释了在基于棉籽的人工饲料和天然饲料（成熟棉铃）上饲养棉铃象甲的动态。根据结果，棉铃象甲的产卵期在人工饲料上（9.07±0.24）比在天然饲料上（7.40±0.11）记录的更长。与天然饲料（60.37±1.10）相比，棉铃象甲在人工饲料上的总产卵量（125.94±3.06）更大。与天然饲料相比，棉铃象甲的种群参数，包括内禀增长率、有限增长率、总繁殖率和净生殖率，在人工饲料上最高。本研究得出的结论是，基于棉籽的人工饲料最适合棉铃象甲的饲养。在未来，可以根据本研究的结果对棉铃象甲进行深入研究。
