【目的】 茶翅蝽Halyomorpha halys Stål是为害猕猴桃果实的重要害虫，且为害日益加重。本研究主要为明确茶翅蝽取食为害后的特征、果实的敏感易受害阶段及果实受害后的品质变化。【方法】 利用田间网罩试验，研究茶翅蝽取食不同发育阶段的猕猴桃果实的受害特征、果实受害率、每果受害点的数量及受害果实品质。【结果】 生长发育阶段的果实受茶翅蝽刺吸为害后，果实表面为绿色或者白色水浸状斑点，受害斑点在果实的各个部位均有发生。其中94.39%为绿色斑点，0.71%为白色斑点，4.90%为绿色与白色斑点混合发生；果实在6月和7月的受害率最高为100%，且在7月受害程度最重，平均每果达到26.00个受害点；受害果实与未受害果实的长、宽、重、硬度、含糖量和干物质含量均未发现显著差异。成熟后的猕猴桃果实受茶翅蝽为害后表现为白色受害点，随着存放时间的增加，受害点的范围逐渐扩大并转变为絮状的腐烂组织，而未受害果实则无明显变化。【结论】 猕猴桃坐果伊始便可受茶翅蝽为害，且持续整个生长发育阶段，其中在较快生长阶段（7月）受害水平最高，成熟后的猕猴桃果实如果保护不及时受到茶翅蝽为害后会缩短贮存期。

[Objectives]  To clarify the characteristics of damage to kiwifruit caused by Halyomorpha halys Stål, a stink bug that is an increasingly important pest of kiwifruit crops but which leaves no obvious signs of damage on the surface of kiwifruit. [Methods]  We used exclosures to study the type of damage inflicted by H. halys on kiwifruit at different stages of growth. [Results]  All kiwifruit examined were measured and peeled to check for damage when they were harvested. Hygrophanous spots were the main kind damage observed, most (94.39%) kiwifruit had green spots, some had both green and white spots (4.90%) and a few (0.71%) had only white spots. These spots could occur anywhere on the fruit. The incidence of H. halys damage was 100% in June and July and the intensity of damage was most severe in July (26.00 spot/fruit). There was no significant difference in the length, width, weight, firmness, sugar content or dry matter content of damaged and undamaged kiwifruit. Damaged postharvest kiwifruit typically had white spongy spots, which gradually expanded becoming flocculent, rotting tissue. Intact kiwifruit underwent no obvious change over the same period of time. [Conclusion]  H. halys can damage kiwifruit anytime between fruit set and harvest. The main growth stage (July) was the most susceptible to damage which shortens the storage period and shelf-life of harvested kiwifruit.
