The brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), is an invasive pest that attacks specialty and row crops in North America and Europe. There has been a concerted effort to reduce frequent broad‐spectrum insecticide applications made on vulnerable crops. One tool that has emerged recently is the use of long‐lasting insecticide‐treated nets (LLINs) as a killing agent. Here, we conducted bioassays to evaluate the effect of direct contact on deltamethrin‐impregnated LLINs on the behaviour and survivorship of H. halys nymphs and adults in the laboratory. Following exposure at three different durations (1.25, 4.25 or 7.25 min), vertical and horizontal mobility of adults and nymphs and the flight capacity of adults were recorded and compared with individuals that were not exposed (control). Exposure to LLINs reduced the horizontal distance and velocity and increased the angular velocity of adults only but reduced vertical mobility of adults and nymphs. Adult flights were not significantly affected by LLIN exposure. Mortality of adults and nymphs at 7‐day post‐exposure ranged from 73% to 77% regardless of exposure time. We discuss our findings within the context of the potential for and limitations of deploying LLINs in vulnerable crops to manage H. halys populations.

掺入溴氰菊酯的蚊帐对实验室内成虫和若虫成虫的迁移和存活的影响

棕色嫁接的臭虫Halyomorpha halysStål（半翅目：昆虫纲）是一种侵袭性害虫，侵袭北美和欧洲的特产和大田作物。为了减少对易受害作物的频繁使用广谱杀虫剂的使用，人们一直在共同努力。最近出现的一种工具是使用经长期杀虫剂处理的蚊帐（LLIN）作为杀灭剂。在这里，我们进行了生物测定，以评估直接接触溴氰菊酯浸渍的LLIN对H. halys行为和存活的影响若虫和成年人在实验室里。在三个不同的持续时间（1.25、4.25或7.25分钟）接触后，记录成年和若虫的垂直和水平运动以及成虫的​​飞行能力，并与未接触的个体进行比较（对照）。暴露于LLIN只会降低成虫的水平距离和速度，并增加成虫的角速度，但会降低成虫和若虫的垂直迁移率。成人飞行不受LLIN暴露的显着影响。暴露后7天，成人和若虫的死亡率在73％至77％之间，与暴露时间无关。我们将在脆弱农作物中部署LLIN来管理H. halys种群的潜力和局限性的背景下讨论我们的发现。
