Histochemical localization of lipid peroxidation induced by α-terthienyl in Aedes albopictus larvae.

Objective To histochemically locate the lipid peroxidation induced by photosensitized α-terthienyl(α-T) in Aedes albopictus larvae.Methods Cold-schiff was employed to observe the Ae.albopictus larvae exposed to photosensitized α-T under optical microscope in comparison to the control group to evaluate the histochemical localization of lipid peroxidation.Results Tissues in the control group remaining unstained,the midgut epithelium,the peritrophic membrane,the brush border and the lumen of malpighian tubules were stained purple in the experimental group.Conclusion Photosensitized α-T could induce lipid peroxidation in tissues of Ae.albopictus larvae,involving primarily the midgut and malpighian tubules.
