摘　　要：茶翅蝽是一种重要的农林害虫,近年来在我国的发生为害程度呈现加重趋势。本文通过田间小区试验和室内行为研究,评价了茶翅蝽成虫对不同植物种类的选择偏好程度。在田间25科115种植物中,84种植物上调查到茶翅蝽成虫,种群发生密度整体较低,但寒麻、芝麻、红麻、籽粒苋、向日葵、大豆、白花菜等植物上成虫密度相对偏高。在室内Y型嗅觉仪测试中,与空白对照相比,茶翅蝽雌雄成虫对苗期和花期的向日葵、大豆、白花菜植株气味均表现出了明显的趋好行为。上述研究结果为深入解析我国茶翅蝽区域分布与发生消长规律提供了科学依据。Halyomorpha halys(Stal) is an important pest in agriculture and forestry, and its occurrence and damage have been increasing in recent years. In this paper, we evaluated the host preference of H.halys adults to different plant species by field-plot trial and laboratory behavioral bioassay. Among 115 plant species from 25 families in field plots in 2014 and 2016, H.halys adults were found on 84 host plants, and the population densities of H.halys adults were generally low, but the population abundance of H.halys adults on Cannabis sativa was the highest, followed by Sesamum indicum, Hibiscus cannabinus, Amaranthus hypochondriacus, Helianthus annuus, Glycine max, and Cleome gynandra. Meanwhile, the adults showed obvious preference to three host plants(i.e., H. annuus, G. max and C. gynandra) at both seedling and flowering stages when compared with the blank control in Y-tube bioassay. These results provide scientific basis for further analysis of the regional distribution and occurrence pattern of H.halys in China.
