The dissipation behaviour and the consumer risk assessment of spitotetramat, flonicamid, imidacloprid and pymetrozine in open field strawberries were studied. Insecticides were applied at the authorised levels and the more critical good agricultural practice regimes (GAP). The initial concentrations varied from 0.069 to 1.75 mg kg depending on the compound, while the dissipation half-lives and terminal residues, 14 days from the last applications, were similar. After application according to the authorised pattern the half-lives were 2.8 days for flonicamid and 3.2 days for spitotetramat, imidacloprid and pymetrozine. The dietary risk assessment, performed using the hazard quotient and the EFSA PRIMo model showed no concern to consumer health with exposure values <2% of the acceptable daily intake (ADI) and <32% of the acute reference dose (ARfD) of each compound.
在露天草莓中研究了螺虫乙酯、氟啶虫酰胺、噻虫啉和吡虫啉的消解行为和消费者风险评估。杀虫剂的使用量为批准用量和更严格的良好农业规范（GAP）用量。初始浓度因化合物而异，范围从 0.069 到 1.75 毫克/千克，而消解半衰期和终端残留量（最后一次施药后 14 天）相似。按照批准的模式施药后，氟啶虫酰胺的半衰期为 2.8 天，螺虫乙酯、噻虫啉和吡虫啉的半衰期为 3.2 天。使用危害商数和 EFSA PRIMo 模型进行的膳食风险评估显示，接触值低于每种化合物的日允许摄入量（ADI）的 2%和急性参考剂量（ARfD）的 32%，不会对消费者健康造成担忧。
