需要开发保护植物免受蚜虫侵袭的新方法。在这里，我们研究了植物防御激活剂，顺式茉莉酮（CJ），在一系列品种的油菜，芜菁和甘蓝。用顺式茉莉酮或空白制剂喷洒植物，然后用桃马铃薯蚜虫（Myzus persicae Sulzer）（半翅目：蚜虫科）和它们的寄生虫Diaeretiella raaicae（M'Intosh）（膜翅目：茧蜂科）测试。在沉降生物测定中，CJ处理的植物具有比对照植物显著更低的蚜虫沉降。相反，在觅食生物测定中，D.在CJ处理的植物上，雷氏寄生蜂花了显著更长的时间觅食。结果表明，CJ处理使植物对M. persicae对桃实蝇D.在一系列芸苔属栽培品种中生长。很可能，这些影响是由于挥发性排放的变化，表明激活防御和存在的同种竞争对手蚜虫，但存在的猎物寄生。CJ诱导的植株挥发性物质排放量增加，但因基因型而异。在CJ处理的芸苔品种的顶空中诱导的合成挥发性化合物中，异硫氰酸甲酯、水杨酸甲酯和顺式茉莉酮对蚜虫具有最大的驱避作用。这些结果建立在拟南芥早期的研究，并表明，三营养相互作用的影响，CJ在广泛的芸苔种质。这意味着，CJ是一种有前途的治疗，可用于芸苔属作物作为一个综合害虫管理系统的一部分。
There is a need to develop new ways of protecting plants against aphid attack. Here, we investigated the effect of a plant defence activator, cis-jasmone (CJ), in a range of cultivars of Brassica napus, Brassica rapa and Brassica oleracea. Plants were sprayed with cis-jasmone or blank formulation and then tested with peach potato aphids (Myzus persicae Sulzer) (Hemiptera: Aphididae) and their parasitoid Diaeretiella rapae (M'Intosh) (Hymenoptera: Braconidae). CJ treated plants had significantly lower aphid settlement than control plants in a settlement bioassay. Conversely, in a foraging bioassay, D. rapae parasitoids spent a significantly longer time foraging on CJ treated plants. Our results reveal that CJ treatment makes plants less attractive to and less suitable for M. persicae but more attractive to D. rapae in a range of brassica cultivars. It is likely that these effects are due to changes in volatile emission indicating activation of defence and presence of conspecific competitors to aphids but presence of prey to parasitoids. Increases in volatile emission were found in CJ induced plants but varied with genotype. Among the synthetic volatile compounds that were induced in the headspace of CJ treated brassica cultivars, methyl isothiocyanate, methyl salicylate and cis-jasmone were most repellent to aphids. These results build on earlier studies in Arabidopsis and show that tritrophic interactions are influenced by CJ in a wide range of brassica germplasm. The implication is that CJ is a promising treatment that could be used in brassica crops as part of an integrated pest management system.
