abstract
current scouting techniques for stink bugs are variable, time-consuming, and costly. the overarching goal of this research was to develop effective and affordable tools for detecting stink bugs and damage induced by stink bugs in cotton. a commercially available electronic nose (cyranose 320) comprising an array of 32 carbon-black composite sensors was used for this purpose and its performance was evaluated under laboratory and field conditions. volatile compounds emitted by stink bugs were confirmed to be trans-2-decenal and trans-2-octenal. four of 32 sensors responded to volatile chemicals produced by bugs and showed responses (smell-prints) to pure trans-2-decenal that were identical to those obtained from stink bugs. under laboratory conditions, internal boll injury (interior walls of bolls and locks with raised callus growths or obvious damage to lint and seed) was predicted 95% of the time and the presence of stink bugs 100% of the time. there was a strong correlation (r2 = 0.95) between the number of stink bugs in a sample and the response of cyranose sensors.
目前对臭虫的侦察技术是可变的、耗时的和昂贵的。本研究的首要目标是开发有效且经济的工具来检测棉花中的臭虫和由臭虫引起的损害。为此，使用了一种商用电子鼻(cyranose 320)，包括32个炭黑复合传感器阵列，并在实验室和现场条件下对其性能进行了评估。臭虫释放的挥发性化合物被证实是反-2-癸烯醛和反-2-辛烯醛。32个传感器中有4个对臭虫产生的挥发性化学物质作出反应，并对纯反式-2-癸烯(与臭虫获得的反式-2-癸烯相同)作出反应(气味印记)。在实验室条件下，预计95%的时间内棉铃内伤害(棉铃和锁的内壁有愈伤组织生长或棉绒和种子明显受损)，100%的时间内有臭虫存在。样品中臭虫的数量与cyranose传感器的响应有很强的相关性(r2=0.95)。
