我们研究了茉莉酸原（PDJ）[（1 RS，2 RS）-（3-氧代-2-戊基环戊基）乙酸丙酯]处理完整利马豆植物对二斑叶螨（TSSMs），二斑叶螨（Tetranychus urticae）的直接防御和植物挥发物的产生的影响。用PDJ或水（对照）处理植物，并将从其叶切下的片暴露于交配的TSSM雌性。3天后，处理之间TSSM死亡率没有显著差异，但雌性在处理过的圆盘上产卵显著减少。用三种不同浓度的PDJ中的一种处理的植物的顶空分析表明，该处理诱导了（Z）-3-己烯基乙酸酯、（E）-β-罗勒烯、（Z）-β-罗勒烯、（E）-4，8-二甲基-1，3，7-壬三烯和β-香芹烯。这些化合物有望影响TSSMs及其天敌的行为反应。
We investigated the effects of prohydrojasmon (PDJ) [propyl (1RS,2RS)-(3-oxo-2-pentylcyclopentyl) acetate] treatment of intact lima bean plants on direct defense against two-spotted spider mites (TSSMs), Tetranychus urticae, and on the production of plant volatiles. Plants were treated with PDJ or water (control) and pieces cut from their leaves were exposed to mated TSSM females. After 3 days, there were no significant differences in TSSM mortality between the treatments, but the females laid significantly fewer eggs on treated disks. Headspace analyses of plants treated with one of three different concentrations of PDJ showed that the treatment induced (Z)-3-hexenyl acetate, (E)-β-ocimene, (Z)-β-ocimene, (E)-4,8-dimethyl-1,3,7-nonatriene, and β-caryophyllene. These compounds were expected to affect the behavioral responses of TSSMs and their natural enemies.
