Secretions from the metathoracic glands (MTG) of the black locust bug, Lopidea robiniae (Uhler) (Heteroptera: Miridae) contained six major compounds, including (E)-2-hexenal, (E)-2-hexen-1-ol, (E)-2-octenal, (E)-2-octen-1-ol (E)-2-heptenal, and (Z)-3-octen-1-ol. Males and females did not differ significantly in the relative compositions of identified compounds. In feeding trials, six bird species [robin (Turdus migratorious), blue jay (Cyanocitta cristata), brown thrasher (Toxostoma rufum), killdeer (Charadrius vociferus), starling (Sturnus vulgaris), and house wren (Troglodytes aedon)] demonstrated feeding aversions towards L. robiniae implying that black locust bugs are chemically defended. Bugs discharged the liquid contents of their MTG when attacked, thereby producing a strong and distinct odor. Some birds immediately ejected bugs out of their mouth after biting them, suggesting that the MTG secretion was a deterrent.
刺槐盲蝽（Lopidea robiniae，乌勒）（半翅目：盲蝽科）后胸腺的分泌物含有六种主要化合物，包括（E）-2-己烯醛、（E）-2-己烯-1-醇、（E）-2-辛烯醛、（E）-2-辛烯-1-醇、（E）-2-庚烯醛和（Z）-3-辛烯-1-醇。已鉴定化合物的相对组成在雄性和雌性之间没有显著差异。在喂食试验中，六种鸟类[知更鸟（Turdus migratorious）、蓝松鸦（Cyanocitta cristata）、褐弯嘴嘲鸫（Toxostoma rufum）、双领鸻（Charadrius vociferus）、椋鸟（Sturnus vulgaris）和家鹪鹩（Troglodytes aedon）]对刺槐盲蝽表现出取食厌恶，这意味着刺槐盲蝽具有化学防御能力。当受到攻击时，盲蝽会排出后胸腺的液体内容物，从而产生强烈而独特的气味。一些鸟类在咬了盲蝽后立即将其从口中吐出，这表明后胸腺分泌物具有威慑作用。
