Phytophagous mites are herbivores that feed on various economically important plants, such as soybean [Glycine max (L.) Merril]. Thus, our objective is to evaluate the oxidative stress stage of plants infested by Tetranychus ludeni Zacher. Leaflets from three trifoliate leaves were pooled form composite samples for each exposure time and evaluated at following evaluation times: 0 h, 20 min, 6 12 24 48 h. In initial phase infestation (20 min), an burst was observed, represented prominent hydrogen peroxide accumulation rather than superoxide radicals. This occurred in parallel a strong increase antioxidant activities catalase, ascorbate peroxidase, glutathione S-transferase, but not dismutase. These changes likely reflected enhanced activation signaling pathways involved response. After this phase, min decrease S-transferases activities, despite levels remaining significantly elevated, along with marked transient reduced content proline. Interestingly, dismutase activity increased after h lipid peroxidation, whereas remained elevated until infestation. By final evaluation, infestation, some redox indicators altered relation control state moderate stress. unprecedented way, data suggest T. triggered response plants. findings highlight proper monitoring management can reduce economic losses without resorting aggressive chemical interventions.

Plants are directly exposed to several biotic factors. Among these, mite species belonging the superfamilies Eriophyoidea and Tetranychoidea stand out due their ability injure or even transmit viruses host plants. In response infestations by these organisms, reactive oxygen (ROS), regulated enzymatic non-enzymatic antioxidants (homeostasis), can act as signaling molecules induce defenses acclimatization in attacked However, depending on severity of stress, there be an imbalance between ROS that result oxidative leading membrane damage lipid peroxidation, organelle inactivation, cell death. this review, we outline for first time current state understanding regarding role cellular processes metabolism, such signaling, potential induced ROS, defense antioxidant systems involved plant–mite relationship. Furthermore, identify gaps redox metabolism plant against phytophagous mites.
