Abstract
Juvenile hormone analogues (JHAs) are known to affect insect growth and can potentially be used in edible insect rearing. In this study, a reversed-phase liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) method was developed for the detection of five common juvenile hormone analogues (fenoxycarb, pyriproxyfen, methoprene, kinoprene, and hydroprene) in mealworms. Sample clean-up was performed using reversed-phase solid-phase extraction cartridges. To enhance ionisation, methoprene, kinoprene, and hydroprene are detected as their 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) derivatives. The method was fully validated according to Commission Implementing Regulation (EU) 2021/808 and is capable of both quantitative and qualitative confirmation of fenoxycarb, pyriproxyfen, methoprene, and kinoprene (CCα values of 6.0-29 µg kg-1), and qualitative screening of hydroprene (with a CCβ of 7.7 µg kg-1). Additionally, it was demonstrated that liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) can also be used for the screening of JHA residues at relevant levels. The LC-MS/MS method was used to demonstrate the presence of methoprene in an incurred sample of mealworms. Finally, 14 mealworm samples originating from the Dutch national residue control plan were analysed, and none of the target analytes were found.
