丛枝菌根(AM)可以改变寄主植物的品质，从而影响植物与食草动物的相互作用。虽然AM可以影响一般食草动物的发育，但AM对昆虫行为的影响一直被忽视。本研究探讨了丛枝菌根真菌对主要车前子植物的表型和叶片代谢特性的影响。此外，还记录了AM介导的寄主植物修饰对油菜夜蛾幼虫发育和7个行为性状的影响。试验分别在3龄(L3)和4龄(L4)幼虫上进行。AM处理植株的地上部分含水量、比叶面积和叶片中次生代谢产物桃叶珊瑚苷的浓度均高于未处理植株，但AM植株叶片中初级代谢产物柠檬酸和异柠檬酸的浓度较低。在AM植物上饲养的幼虫比在NM植物上饲养的个体获得更高的体质量，并倾向于更快地发育。然而，植物处理对任何行为特征都没有显著影响。相反，不同年龄的幼虫在几个行为特征上存在差异，L4幼虫比L3幼虫活泼和大胆。结果表明，AM诱导的寄主植物质量的改变影响幼虫的发育，而行为表型似乎更固定，至少在所测试的条件下是这样。
Arbuscular mycorrhiza (AM) formed between plants and AM fungi (AMF) can alter host plant quality and thus influence plant-herbivore interactions. While AM is known to affect the development of generalist chewing-biting herbivores, AM-mediated impacts on insect behavior have been neglected until now. In this study, the effects ofRhizophagus irregularis, a generalist AMF, on phenotypic and leaf metabolic traits ofPlantago majorplants were investigated. Further, the influence of AM-mediated host plant modifications on the development and on seven behavioral traits of larvae of the generalistMamestra brassicaewere recorded. Tests were carried out in the third (L3) and fourth (L4) larval instar, respectively. While shoot water content, specific leaf area, and foliar concentrations of the secondary metabolite aucubin were higher in AM-treated compared to non-mycorrhized (NM) plants, lower concentrations of the primary metabolites citric acid and isocitric acid were found in leaves of AM plants. Larvae reared on AM plants gained a higher body mass and tended to develop faster than individuals reared on NM plants. However, plant treatment had no significant effect on any of the behavioral traits. Instead, differences between larvae of different ages were detected in several behavioral features, with L4 being less active and less bold than L3 larvae. The results demonstrate that AM-induced modifications of host plant quality influence larval development, whereas the behavioral phenotype seems to be more fixed at least under the tested conditions.
