Qualitative Detection of Lipid Peroxidation in Mosquito Larvae Using Schiff’s Reaction: A Simple Histochemical Tool for In Situ Assessment of Oxidative Damage

and other biological models exposed to multiple stressors. Key features • Direct qualitative assessment: Provides visual, histochemical evidence of lipid peroxidation in situ, enabling rapid evaluation of oxidative membrane damage at the tissue and whole-organism levels. • Preservation of spatial context: Allows localization of oxidative damage without tissue homogenization, maintaining tissue architecture and spatial resolution. • Environmental and toxicological screening: Optimized for rapid detection of oxidative stress in mosquito larvae exposed to larvicides, biocontrol agents, and other environmental stressors. • Complementary to quantitative assays: Functions as a screening tool that complements spectrophotometric methods such as thiobarbituric acid reactive substances (TBARS).
