Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is one of the most important herbivores in a broad range of cultivated plants, including cotton, cereals, vegetables, and fruit crops in China. In this manuscript, we report on a 6-year long study in which (adult) A. lucorum abundance was recorded on 174 plant species from 39 families from early July to mid-September. Through the study period per year, the proportion of flowering plants exploited by adult A. lucorum was significantly greater than that of non-flowering plants. For a given plant species, A. lucorum adults reached peak abundance at the flowering stage, when the plant had the greatest attraction to the adults. More specifically, mean adult abundance on 26 species of major host plants and their relative standard attraction were 10.3-28.9 times and 9.3-19.5 times higher at flowering stage than during non-flowering periods, respectively. Among all the tested species, A. lucorum adults switched food plants according to the succession of flowering plant species. In early July, A. lucorum adults preferred some plant species in bloom, such as Vigna radiata, Gossypium hirsutum, Helianthus annuus and Chrysanthemum coronarium; since late July, adults dispersed into other flowering hosts (e.g. Ricinus communis, Impatiens balsamina, Humulus scandens, Ocimum basilicum, Agastache rugosus and Coriandrum sativum); in early September, they largely migrated to flowering Artemisia spp. (e.g. A. argyi, A. lavandulaefolia, A. annua and A. scoparia). Our findings underscore the important role of flowering plays in the population dynamics and inter-plant migration of this mirid bug. Also, our work helps understand evolutionary aspects of host plant use in polyphagous insects such as A. lucorum, and provides baseline information for the development of sustainable management strategies of this key agricultural pest.
中华通草蛉（Meyer-Dür）（半翅目：盲蝽科）是中国广泛种植的棉花、谷物、蔬菜和水果等作物的重要食草动物之一。在本研究中，我们报告了一项为期 6 年的研究，该研究于 7 月初至 9 月中旬在 39 个科的 174 种植物上记录了成虫的数量。在整个研究期间，中华通草蛉利用的开花植物比例显著高于非开花植物。对于特定的植物物种，中华通草蛉成虫在开花期达到数量高峰，此时植物对成虫的吸引力最大。具体而言，26 种主要宿主植物在开花期的平均成虫数量及其相对标准吸引力分别比非开花期高 10.3-28.9 倍和 9.3-19.5 倍。在所有测试的物种中，中华通草蛉成虫根据开花植物物种的演替来转换食物植物。7 月初，中华通草蛉成虫偏爱一些开花植物，如豇豆、棉花、向日葵和菊花；7 月下旬以后，成虫分散到其他开花的宿主植物中（如蓖麻、凤仙花、葎草、罗勒、荆芥和芫荽）；9 月初，它们大量迁移到开花的艾蒿属植物（如艾草、香叶艾、青蒿和野艾蒿）。我们的研究结果强调了开花在这种盲蝽种群动态和植物间迁移中的重要作用。此外，我们的工作有助于理解中华通草蛉等多食性昆虫对寄主植物利用的进化方面，并为这种关键农业害虫的可持续管理策略提供了基线信息。
