调查表明,储存虫子在储存过程中严重损害谷物。在此期间,精油(EO)已被证明是一种良好的植物源农药。纤毛Elsholtziaciliata精油的抗蛇床病特性,它是通过蒸汽蒸馏获得的,使用DL-柠檬烯进行评估,Carvone,和它们的两个旋光异构体成分接触,排斥,和熏蒸技术。同时,熏蒸,联系人,并评估了香芹酮及其与DL-柠檬烯混合的两种光学异构体对L.serruricorne的驱除活性。结果表明,纤毛,其主要部件(R-carvone,DL-柠檬烯),S-香芹酮对L.serricorne表现出熏蒸(LC50=14.47、4.42、20.9和3.78mg/L)和接触(LD50=7.31、4.03、28.62和5.63µg/成人)活性。R-香芹酮和DL-柠檬烯的二元混合物(1:1)显示出明显的协同作用。香芹酮及其两种旋光异构体的二元混合物(1:1)表现出明显的协同作用,也是。此外,EO的驱虫活性,Carvone,和它的两个光学异构体,DL-柠檬烯,它们的组合各不相同。为了在储存过程中阻止昆虫的伤害,纤毛虫及其组分可用作生物杀虫剂。
Investigations have shown that storage bugs seriously harm grains during storage. In the interim, essential oils (EOs) have been proven to be a good botanical pesticide. The anti-Lasioderma serricorne properties of Elsholtzia ciliata essential oil, which was obtained by steam distillation, were evaluated using DL-
limonene, carvone, and their two optical isomer components using contact, repelling, and fumigation techniques. Simultaneously, the fumigation, contact, and repellent activities of carvone and its two optical isomers mixed with DL-
limonene against L. serruricorne were evaluated. The results showed that E. ciliata, its main components (R-carvone, DL-
limonene), and S-carvone exhibited both fumigations (LC50 = 14.47, 4.42, 20.9 and 3.78 mg/L) and contact (LD50 = 7.31, 4.03, 28.62 and 5.63 µg/adult) activity against L.serricorne. A binary mixture (1:1) of R-carvone and DL-
limonene displayed an obvious synergistic effect. A binary mixture (1:1) of carvone and its two optical isomers exhibited an obvious synergistic effect, too. Furthermore, the repellent activity of the EO, carvone, and its two optical isomers, DL-
limonene, and a combination of them varied. To stop insect damage during storage, E. ciliata and its components can be utilized as bio-insecticides.
