cis-Jasmone is a plant volatile known to have roles as an insect semiochemical and in inducing plant defence. It was evaluated in laboratory and field trials for control of cereal aphids. In an olfactometer bioassay cis-jasmone was repellent to alatae of the grain aphid, Sitobion avenae (Fabricius) (Homoptera: Aphididae). Moreover, wheat, Triticum aestivum (L), seedlings sprayed with formulated cis-jasmone 24 h previously were less susceptible to attack by S. avenae than control plants. In field simulator studies, significantly fewer alate S. avenae settled on cis-jasmone-treated plants over a 24-h period. In addition, the intrinsic rate of population increase, r(m), of S. avenae apterae was reduced on cis-jasmone treated seedlings. In a series of small-plot experiments conducted over four years, cis-jasmone applications reduced cereal aphid populations infesting wheat in the field.
顺式茉莉酮是一种植物挥发物，已知它具有昆虫信息素的作用并能诱导植物防御。对其进行了实验室和田间试验以防治谷物蚜虫。在嗅觉测定生物测定中，顺式茉莉酮对麦长管蚜（Sitobion avenae (Fabricius)，同翅目：蚜科）的有翅蚜具有驱避作用。此外，提前24小时用配制好的顺式茉莉酮喷洒的小麦（Triticum aestivum (L)）幼苗比对照植物更不易受到麦长管蚜的侵害。在田间模拟器研究中，在24小时内，落在顺式茉莉酮处理过的植株上的有翅麦长管蚜明显更少。此外，在顺式茉莉酮处理过的幼苗上，麦长管蚜无翅蚜的种群内禀增长率r(m)降低。在连续四年进行的一系列小区试验中，施用顺式茉莉酮减少了田间侵害小麦的谷物蚜虫种群数量。
