The brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is a significant threat to crop production. Alternatives to synthetic pesticides are needed for its management. Here we investigated the effect of sulphur on H. halys. Experiments were performed to evaluate both mortality and deterrence/repellence of H. halys following sulphur treatments in laboratory and semi-field conditions.
Brown marmorated stink bug mortality was not influenced by sulphur applications. However, in two-choice experiments in insect cages and olfactometer, more H. halys adults moved toward the untreated control rather than the sulphur-treated food sources, with a high effect as the concentration increased. A semi-field experiment using potted apple plants confirmed the results observed in the laboratory, showing a deterrent and/or repellent effect of sulphur-based products on H. halys.
Sulphur applications were associated with a deterrent/repellent effect on the brown marmorated stink bug. The use of sulphur-based products could represent a promising tool for Integrated Pest Management strategies against H. halys in fruit crops. © 2024 The Authors.

褐带丽盲蝽（Halyomorpha halys（Stål））（半翅目：盲蝽科）是作物生产的重大威胁。需要替代合成农药来对其进行管理。本文研究了硫磺对褐带丽盲蝽的影响。在实验室和半野外条件下进行了硫磺处理对褐带丽盲蝽死亡率和驱避/拒食作用的实验。
硫磺处理并不影响褐带丽盲蝽的死亡率。然而，在昆虫笼和嗅觉计中的双选择实验中，更多的成年褐带丽盲蝽趋向于未处理的对照而不是硫磺处理的食物源，随着浓度的增加，效果很高。使用盆栽苹果树的半野外实验证实了在实验室中观察到的结果，表明硫磺产品对褐带丽盲蝽具有驱避和/或拒食作用。
硫磺处理对褐带丽盲蝽具有驱避/拒食作用。硫磺产品的使用可能代表了针对水果作物中褐带丽盲蝽的综合虫害管理策略的有前途的工具。©2024 作者。害虫管理科学由 John Wiley & Sons Ltd 代表化学工业协会出版。
