(Coleoptera: Cerambycidae) is an economically important wood-boring insect pest of stone fruit trees, particularly , in China. It has entered Japan and several European countries as an invasive species in recent years. It is difficult to control because of the cryptic feeding behaviour of larvae beneath the bark. Identification of repellent constituents from non-host plants has potential for use in management strategies against this beetle. is cultivated extensively in Hebei Province (China) as a medicinal plant. Firstly, antennal responses of female to volatiles were evaluated by coupled gas chromatography-electroantennograms (GC-EAD), and then the EAD-active components were tested in semi-field trials. The results showed that females were significantly repelled by myrcene, ()-(+)-carvone, ()-β-caryophyllene, and borneol compared with the control. The presence of myrcene (100 µL; 90% purity), ()-(+)-carvone (200 µL; 96% purity), ()-β-caryophyllene (500 µL; 98.5% purity), and borneol (800 µL; 80% purity) significantly reduced the perching rates of females on both peach logs and leaves. Considering cost and commercial availability, we suggest that myrcene, ()-(+)-carvone, and ()-β-caryophyllene could be promising repellents against females in the field.
(鞘翅目:天牛科)是一种对核果类果树具有重要经济影响的蛀木害虫,在中国尤其如此。近年来,它作为一种入侵物种进入了日本和几个欧洲国家。由于其幼虫在树皮下方具有隐匿的取食行为,因此很难进行防治。从非寄主植物中鉴定驱避成分具有用于针对这种甲虫的管理策略的潜力。在中国河北省广泛种植作为药用植物。首先,通过气相色谱 - 触角电图联用(GC - EAD)评估了雌性[昆虫名称未给出]对[植物名称未给出]挥发物的触角反应,然后在半田间试验中测试了EAD活性成分。结果表明,与对照相比,月桂烯、() - ( + ) - 香芹酮、() - β - 石竹烯和冰片对雌性[昆虫名称未给出]有显著的驱避作用。月桂烯(100 μL;90%纯度)、() - ( + ) - 香芹酮(200 μL;96%纯度)、() - β - 石竹烯(500 μL;98.5%纯度)和冰片(800 μL;80%纯度)的存在显著降低了雌性[昆虫名称未给出]在桃原木和叶片上的栖息率。考虑到成本和商业可得性,我们建议月桂烯、() - ( + ) - 香芹酮和() - β - 石竹烯可能是在田间对雌性[昆虫名称未给出]有前景的驱避剂。
