This study investigated insecticidal activity of Artemisia herba-alba essential oil (EO) against Tribolium castaneum adults and its impacts on wheat flour quality. GC/MS analysis of the EOs of A. herba-alba showed a predominance of β-thujone (27.79%), camphor (22.65%), chrysanthenone (17.97%) and α-thujone (13.56%). Therefore, the median effective concentrations (LC50 value) of Artemisia herba-alba essential oil used for preliminary screening tests were evaluated. Insect mortalities, occupation space conditions and wheat flour quality were investigated after 30 and 60 days of storage period. The results showed that mortality varies depending on occupation space and storage duration, which reached 42.15% and 59.8% after 30 and 60 days of storage, respectively. Furthermore, moisture, ash, gluten, falling number contents were examined according to international standards. Indeed, rheological dough parameters were examined using a Chopin alveograph and according to ISO standards. Results indicated that A. herba-alba essential oil changed wheat flour physicochemical parameters but did not affect dough rheological parameters which correspond to international ISO standards.

青蒿的杀虫活性及其对小麦粉贮藏品质的影响

这项研究调查了艾草（Artemisia herba-alba）精油（EO）对非洲bol藜（Tribolium castaneum）成虫的杀虫活性及其对小麦粉品质的影响。GC / MS分析赫氏曲霉的EOs显示，β-thujone（27.79％），樟脑（22.65％），chrysanthenone（17.97％）和α-thujone（13.56％）占优势。因此，青蒿的平均有效浓度（LC50值）对用于初步筛选测试的精油进行了评估。在储存30天和60天后调查昆虫的死亡率，占领空间条件和小麦粉的质量。结果表明，死亡率随占用空间和存放时间的不同而不同，分别在存放30天和60天后分别达到42.15％和59.8％。此外，根据国际标准检查了水分，灰分，面筋，落数含量。的确，使用肖邦（Chopin）测振仪并根据ISO标准检查了流变面团参数。结果表明，A.herba-alba精油改变了小麦粉的理化参数，但不影响面团流变学参数，这符合国际ISO标准。
