Abstract
The soybean aphid, Aphis glycines Matsumura, 1917, is a crucial soybean pest. Cultivated soybean, Glycine max (Carl von Linné) Elmer Drew Merrill, 1917, and wild soybean, Glycine soja Philipp Franz von Siebold & Joseph Gerhard Zuccarini, 1843, are summer hosts of A. glycines. In this study, the development, reproduction, and morphogenesis of A. glycines fed wild soybean (AgFW) were studied at different temperatures and photoperiods. The data were compared with that of A. glycines fed soybean (AgFS). At 20-29 °C, the adult lifespan of the first-third-generation AgFW was shorter than or equal to that of AgFS. Significant differences existed in the adult fecundity and intrinsic rate of increase between AgFW and AgFS. At a 10L:14D h photoperiod, males of AgFW were deposited earlier than, or as early as, males of AgFS. At 17 °C, the gynoparae of AgFW were deposited in proportions greater than or equal to those of AgFS. Based on these results, we concluded that the adaptability of AgFW and AgFS to temperature and photoperiod significantly differs. It is important to understand the life cycle of A. glycines in Harbin, northeast China, and formulate an integrated pest management strategy for A. glycines in the region.
大豆蚜虫 Aphis glycines Matsumura, 1917 是一种重要的大豆害虫。栽培大豆(Glycine max (Carl von Linné) Elmer Drew Merrill, 1917 年)和野生大豆(Glycine soja Philipp Franz von Siebold & Joseph Gerhard Zuccarini, 1843 年)是甘蚜的夏季寄主。在本研究中,研究了在不同温度和光周期下以野生大豆(AgFW)为食的甘蓝触角虫的发育、繁殖和形态发生。将这些数据与喂食大豆(AgFS)的甘蓝甲虫的数据进行了比较。在 20-29 °C条件下,第一代至第三代AgFW的成虫寿命短于或等于AgFS。AgFW 和 AgFS 的成虫繁殖力和内在增长率存在显著差异。在 10L:14D h 的光周期下,AgFW 的雄性比 AgFS 的雄性更早着床或与 AgFS 的雄性一样早着床。17 °C时,AgFW的雌蕊沉积比例大于或等于AgFS的雌蕊沉积比例。基于这些结果,我们得出结论:AgFW 和 AgFS 对温度和光周期的适应性存在显著差异。了解东北哈尔滨地区甘蓝夜蛾的生活周期,对制定该地区甘蓝夜蛾害虫综合防治策略具有重要意义。

期刊介绍:
Insects (ISSN 2075-4450) is an international, peer-reviewed open access journal of entomology published by MDPI online quarterly. It publishes reviews, research papers and communications related to the biology, physiology and the behavior of insects and arthropods. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
