It is still vague how SA activates plant defence against herbivores such as chewing and sucking pests. Here, we used an aphid-susceptible wheat variety to investigate\n                    <jats:italic>Sitobion avenae<\/jats:italic>\n                    response to SA-induced wheat plants, and the effects of exogenous SA on some defence enzymes and phenolics in the plant immune system. In SA-treated wheat seedlings, intrinsic rate of natural increase (\n                    <jats:italic>r<\/jats:italic>\n                    <jats:sub>m<\/jats:sub>\n                    ), fecundity and apterous rate of\n                    <jats:italic>S. avenae<\/jats:italic>\n                    were 0.25, 31.4 nymphs\/female and 64.4%, respectively, and significantly lower than that in the controls (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.05). Moreover, the increased activities of phenylalanine-ammonia-lyase, polyphenol oxidase (PPO) and peroxidase in the SA-induced seedlings obviously depended on the sampling time, whereas activities of catalase and 4-coumarate:CoA ligase were suppressed significantly at 24, 48 and 72 h in comparison with the control. Dynamic levels of\n                    <jats:italic>p<\/jats:italic>\n                    -coumaric acid at 96 h, caffeic acid at 24 and 72 h and chlorogenic acid at 24, 48 and 96 h in wheat plants were significantly upregulated by exogenous SA application. Nevertheless, only caffeic acid content was positively correlated with PPO activity in SA-treated wheat seedlings (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.031). These findings indicate that exogenous SA significantly enhanced the defence of aphid-susceptible wheat variety against aphids by regulating the plant immune system, and may prove a potential application of SA in aphid control.\n                  <\/jats:p>","DOI":"10.1017\/s0007485321000237","type":"journal-article","created":{"date-parts":[[2021,4,5]],"date-time":"2021-04-05T01:00:27Z","timestamp":1617584427000},"page":"544-552","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":29,"title":["Exogenous salicylic acid improves resistance of aphid-susceptible wheat to the grain aphid,\n                    <i>Sitobion avenae<\/i>\n                    (F.)
