【摘要】 烟青虫Helicoverpa assulta(Guenée,1852)现今分布于东亚、东南亚、大洋洲和非洲等地,但其起源地尚不清楚。本文在梳理烟青虫分类地位和系统发生资料的基础上,根据其食性、习性、地理分布及其与重要寄主植物烟草分布格局关系等资料,推断其起源地很可能是热带雨林地域。同时从烟青虫种群特性以及人类活动、大陆漂移理论等因素的作用对该推断进行解析。更多还原

【Abstract】 The oriental tobacco budworm Helicoverpa assulta(Guenée, 1852) is currently distributed in East Asia, Southeast Asia, Oceania and Africa. However, the origin of this pest remains unknown. In this paper, we review evolutionary relationships among the Heliothinae with emphasis on the phylogeny of H. assulta. Based on its feeding habits, behavior, distribution patterns and host plant range, we infer that H. assulta most likely originated from tropical rain forest regions. We justify this inference with factors associated with the population characteristics of H. assulta, including human activities and plate tectonics.更多还原
