上海市闵行区螽斯和蟋蟀的种类及生活史报道

Species and life cycles report on Tettigoniidea and Gryllidea in Minhang District,Shanghai

于2020年和2021年的4—12月,每两周对上海市闵行区浦江郊野公园内的螽斯与蟋蟀种类进行连续调查.研究结果显示,该地区分布有螽斯8种、蟋蟀16种、蝼蛄1种.通过对它们生活史进行研究发现,其成虫时间十分规律,化性稳定,主要通过卵滞育的方式越冬,其次为若虫越冬.此外,还发现通过鸣声对物种进行鉴定,是一种进行鸣虫物候学研究与生态学研究的简便易行的方法.

This research study focuses on Tettigoniidea and Gryllidea insects distributed across Shanghai Pujiang Country Park,with data collected twice a month from April to December of Year 2020 and 2021.The results show that 8 species of Tettigonioidea,16 species of Grylloidea,and 1 species of Gryllotalpidae live in Shanghai Pujiang Country Park.The adult phase and voltinism in their life cycles,moreover,were found to be stable.Most Tettigoniidea and Gryllidea tend to overwinter in soil as diapause eggs,and a proportion of them overwinter as nymphs.The research suggests,furthermore,that using the calling songs of Tettigoniidea and Gryllidea can be a simple and effective way to carry out studies about phenology and ecology of singing insect.
