Chemical composition of Algerian Mentha rotundifolia and Myrtus communis essential oils, their insecticidal activities and their impact on some biological parameters of the Mediterranean flour moth Ephestia kuehniella were assessed. Results showed that M. rotundifolia essential oil contained piperitenone oxide (46.06%), d-limonene (9.10%), cis-piperitone oxide (6.81%), and endo-borneol (4.64%) as major compounds, while M. communis oil was rich in α-pinene (29.08%), 1,8-cineole (36.82%), α-terpineol (6.42%), geranyl acetate (4.38%), and β-linalool (4.04%). The fumigant potential and contact toxicity tests against E. kuehniella demonstrated the effectiveness of M. rotundifolia essential oil (LC₅₀ = 0.54 μL/L air, LC₅₀ = 0.004 μL/cm²) compared to M. communis oil (LC₅₀ = 2.91 μL/L air, LC₅₀ = 0.025 μL/cm²). Moreover, results revealed that all biological parameters were significantly affected (fecundity: 6 eggs/female, oviposition deterrence: 96.62%, log fertility: 0, hatching rate: 0%, copulation rate: 0% for M. rotundifolia oil against fecundity: 93 eggs/female, percentage of oviposition deterrence: 47.85%, log fertility: 6.7, hatching rate: 57%, copulation rate: 53.33% for M. communis oil). This work supports the use of botanical insecticide as active pest control agents under storage conditions.

筛选两种阿尔及利亚精油的杀虫功效，其中特别要考虑它们对埃弗氏菌（Zeller）（鳞翅目：Pyralidae）生物学参数的影响

评估了阿尔及利亚薄荷（Mentus rotundifolia）和桃金娘（Myrtus communis）精油的化学成分，杀虫活性以及对地中海粉蛾Ephestia kuehniella某些生物学参数的影响。结果表明，圆叶雪茄精油中主要成分为氧化哌啶酮氧化物（46.06％），d-柠檬烯（9.10％），顺式哌啶酮氧化物（6.81％）和内降冰片酚（4.64％），而山茱M油为主要成分。富含α-pine烯（29.08％），1,8-桉树脑（36.82％），α-松油醇（6.42％），乙酸香叶酯（4.38％）和β-芳樟醇（4.04％）。对库氏大肠杆菌的熏蒸潜力和接触毒性测试证明了罗汉果精油（LC ₅₀  = 0.54μL/ L空气，LC ₅₀  = 0.004μL/ cm ²）与Communis Communis油（LC ₅₀  = 2.91μL/ L空气，LC ₅₀  = 0.025μL/厘米²）。此外，结果显示，所有生物学参数均受到显着影响（繁殖力：M。rotundifolia油对繁殖力：繁殖力：6个卵/雌性，产卵抑制力：96.62％，对数繁殖力：0，孵化率：0％，交配率：0％）。产卵威慑粒/雌，百分比：47.85％，日志生育能力：6.7，孵化率57％，交配率：53.33％M.群落油）。这项工作支持在储存条件下使用植物性杀虫剂作为活性害虫防治剂。
