To determine whether black soldier fly and lesser mealworm larvae tolerate, accumulate, metabolize, or excrete four major agricultural mycotoxins present in their feed substrates.
Reared Alphitobius diaperinus and Hermetia illucens larvae on feed spiked with aflatoxin B1, deoxynivalenol, ochratoxin A, or zearalenone—individually and as a mixture—at 1, 10, and 25 times European Commission maximum feed limits.
Quantified parent mycotoxins and specific metabolites in larvae and residual material using a validated LC-MS/MS method and performed mass balance calculations.
Neither insect species accumulated mycotoxins; tissue levels in Hermetia illucens remained several orders of magnitude below dietary concentrations.
Larval development and toxin kinetics did not differ between individual mycotoxin exposures and mycotoxin mixtures.
Both species successfully metabolized or excreted the toxins, with zearalenone metabolites accounting for up to an average maximum of 86% of the mass balance in Hermetia illucens.

Implication

Laboratory feeding trial demonstrates efficient excretion and metabolism of dietary mycotoxins in insect larvae, indicating potential tolerance to contaminated feed.
