Plants are attacked by a variety of herbivores and respond with localized or systemic defenses. Plant defense against one feeding guild (e.g. chewing, piercing/sucking) may also affect alternate feeding guilds. To optimize host plant resistance, interactions between feeding guilds must be understood. Aphids are plant virus vectors whose vector efficiency can be altered by plant defenses. To determine if systemic induction influences aphid feeding behaviors related to virus transmission, three soybean varieties, Davis, Lyon, and Progeny 4906RR, were induced by subjecting plants to soybean looper (SBL) herbivory, or exogenous applications of either jasmonic acid (JA) or salicylic acid (SA). Green peach aphid (GPA) apterae feeding behavior was recorded on induced and control plants using the Electrical Penetration Graph (EPG) technique. SBL growth bioassays were used to assess systemic induction. Previous SBL herbivory reduced SBL larval weights when fed Progeny 4906RR. JA reduced larval weights on Progeny 4906RR and Davis. SA increased SBL larval weights on Lyon. SBL herbivory decreased behaviors associated with nonpersistent virus transmission in Davis and Progeny 4906RR. JA altered behaviors associated with virus transmission in Davis and increased behaviors associated with virus acquisition in Progeny 4906RR. SA delayed probing in Davis, but increased behaviors associated with virus transmission in Progeny 4906RR and Lyon. Inducing host plant resistance with JA may reduce herbivore performance and increase nonpersistent virus transmission. Previous chewing herbivory may decrease nonpersistent virus transmission by aphids but is variety dependent.

植物受到各种食草动物的攻击，并以局部或系统防御方式做出反应。植物对一个进食行会的防御（例如咀嚼，刺穿/吮吸）也可能影响其他进食行会。为了优化寄主植物的抗性，必须了解饲养协会之间的相互作用。蚜虫是植物病毒载体，其载体效率可以通过植物防御而改变。为了确定系统性诱导是否影响与病毒传播有关的蚜虫取食行为，通过使植物遭受大豆弯er（SBL）食草植物或外源施用茉莉酸（JA）或大豆外来诱导三种大豆变种，戴维斯，里昂和Progeny 4906RR。水杨酸（SA）。使用电渗透图（EPG）技术在诱导植物和对照植物上记录了桃蚜（GPA）的桃蚜取食行为。SBL生长生物测定法用于评估全身诱导。喂食Progeny 4906RR后，以前的SBL食草动物减少了SBL幼虫的体重。JA减少了Progeny 4906RR和Davis的幼虫体重。SA增加了里昂的SBL幼虫体重。在戴维斯和Progeny 4906RR中，SBL食草动物减少了与非持久性病毒传播相关的行为。JA改变了戴维斯病毒传播的相关行为，并增加了Progeny 4906RR中病毒获取的相关行为。SA推迟了戴维斯的探测，但在Progeny 4906RR和里昂增加了与病毒传播有关的行为。用JA诱导寄主植物抗性可能会降低草食动物的性能并增加非持久性病毒传播。以前咀嚼的草食动物可能会减少蚜虫的非持久性病毒传播，但取决于品种。
