The cotton bollworm, Helicoverpa armigera is a polyphagous pest in Asia, Africa, and the Mediterranean Europe. Salicylic acid (SA) and jasmonic acid (JA) are the cell signaling molecules produced in response to insect attack in plants. The effect of these signaling molecules was investigated on the oxidative phosphorylation and oxidative stress of H. armigera. SA significantly inhibited the state III and state IV respiration, respiratory control index (RCI), respiratory complexes I and II, induced mitochondrial swelling, and cytochrome c release in vitro. Under in vivo conditions, SA induced state IV respiration as well as oxidative stress in time- and dose-dependent manner, and also inhibited the larval growth. In contrast, JA did not affect the mitochondrial respiration and oxidative stress. SA affected the growth and development of H. armigera, in addition to its function as signaling molecules involved in both local defense reactions at feeding sites and the induction of systemic acquired resistance in plants.

植物细胞信号分子、水杨酸和茉莉酸与棉铃虫线粒体的相互作用。

棉铃虫 Helicoverpa armigera 是亚洲、非洲和地中海欧洲的杂食性害虫。水杨酸 (SA) 和茉莉酸 (JA) 是植物响应昆虫攻击而产生的细胞信号分子。研究了这些信号分子对棉铃虫氧化磷酸化和氧化应激的影响。SA 在体外显着抑制状态 III 和状态 IV 呼吸、呼吸控制指数 (RCI)、呼吸复合物 I 和 II，诱导线粒体肿胀和细胞色素 c 释放。在体内条件下，SA以时间和剂量依赖性方式诱导IV状态呼吸以及氧化应激，并抑制幼虫生长。相比之下，JA 不影响线粒体呼吸和氧化应激。SA影响棉铃虫的生长发育，
