顺式茉莉素是一种植物挥发物，已知具有昆虫的符号化学作用和诱导植物防御作用。在室内和田间试验中对其防治效果进行了评价。用嗅觉生物测定法测定了顺式茉莉素对禾草蚜虫（同翅目：蚜虫科）的一种幼虫有驱避作用。此外，小麦、小麦（Triticum aestivum， L）幼苗在24 h前喷洒配方顺式茉莉后，对S avenae的易感程度低于对照植株。在田间模拟研究中，在24小时内，在顺式茉莉处理过的植物上定居的酸盐S avenae明显减少。此外，顺式茉莉花处理降低了叶蝉的内在种群增长率r(m)。在为期四年的一系列小块试验中，施用顺式茉莉素减少了田间小麦上的谷物蚜虫数量。(C) 2003年化学工业学会。
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. (C) 2003 Society of Chemical Industry.
