Implication

Experimental study demonstrates predatory mite biocontrol reduces oxidative stress in two-spotted spider mite-infested cucumber plants, highlighting its advantage over chemical pesticides.

Key Points

  • To evaluate the effects of chemical control with abamectin versus biological control with the predatory mite Neoseiulus californicus on oxidative stress and redox homeostasis in cucumber plants infested with Tetranychus urticae.
  • Assigned cucumber plants under controlled conditions to five groups: untreated control, T. urticae infestation, infestation with biological control (N. californicus), infestation with abamectin, and uninfested plants treated with abamectin.
  • Measured photosynthetic pigments, oxidative stress markers, and antioxidant enzyme activities, analyzing group differences using analysis of variance (ANOVA) and Tukey's test (p ≤ 0.05).
  • Biological control using N. californicus suppressed T. urticae populations while mitigating oxidative damage, maintaining lipid peroxidation levels and antioxidant enzyme activities near untreated baseline levels.
  • Chemical control with abamectin heightened oxidative stress in plants, causing greater accumulation of reactive oxygen species and elevated antioxidant enzyme activity representing an added metabolic cost.
