The mealworm Tenebrio molitor L. (Coleoptera: Tenebrionidae) feeds on wheat bran and is considered both
a pest and an edible insect. Its larvae contain proteins and essential amino acids, fats, and minerals, making
them suitable for animal and human consumption. Zearalenone (ZEA) is the mycotoxin most commonly as-
sociated with Fusarium spp. It is found in cereals and cereal products, so their consumption is a major risk for
mycotoxin contamination. One of the most important effects of ZEA is the induction of oxidative stress, which
leads to physiological and behavioral changes. This study deals with the effects of high doses of ZEA (10 and
20 mg/kg) on survival, molting, growth, weight gain, activity of antioxidant enzymes superoxide dismutase
(SOD) and glutathione S-transferase (GST), and locomotion of mealworm larvae. Both doses of ZEA were
found to (i) have no effect on survival, (ii) increase molting frequency, SOD, and GST activity, and (iii) decrease
body weight and locomotion, with more pronounced changes at 20 mg/kg. These results indicated the suscep-
tibility of T. molitor larvae to high doses of ZEA in feed.
