Abstract

ABSTRACT: In this research, the effects of essential oils isolated from four ecotypes of cumin (Cuminum cyminum L.) Northern-Khorasan (NS), Fars (FS), Kerman (KK), and Kerman (KR) were evaluated on the 4th instar larvae of pink stem borer, Sesamia cretica Lederer. The essential oils were extracted from seeds and the chemical composition was assessed via Gas Chromatography-Mass Spectrometry (GC-MS). Cuminaldehyde (43.599-55.939%), γ-terpinene (13.134-21.750%), m-cymene (8.349-16.935%), ß-pinene (6.320-14.130%), and α-phellandrene (2.137-4.742%) were the main components of the essential oils. Four types of blood cells: prohaemocytes, plasmatocyte, granulocyte, and oenocytoid were identified in the haemolymph of the 4th instar larvae of S. cretica. The decreasing haemocyte counts were found to be significant in the different ecotypes of C. cyminum essential oil. The utilized concentrations and specified times had significant effects on the reductions of the mentioned cell numbers. The fewest number of cells for all ecotypes was measured after 48 h. The highest decline in the total haemocyte count was related to the concentration of 8000 ppm in NS ecotype. The lowest LC50 value was observed in KR ecotype. Based on the results of the present study, the essential oils isolated from the different ecotypes of C. cyminum showed to be promising candidates for S. cretica management.

四种生态型孜然精油对粉红茎螟(Sesamia cretica Ledere)血细胞的影响

摘要:本实验研究了四种不同生态型孜然(Cuminum cyminum L.)挥发油对植物生长的影响。研究了北呼罗珊(NS)、法尔斯(FS)、克尔曼(KK)和克尔曼(KR)对粉螟4龄幼虫的处理效果。从种子中提取精油，采用气相色谱-质谱联用技术(GC-MS)测定其化学成分。孜然醛(43.599 ~ 55.939%)、γ-松油烯(13.134 ~ 21.750%)、间伞花烯(8.349 ~ 16.935%)、ß-蒎烯(6.320 ~ 14.130%)、α-茶香烯(2.137 ~ 4.742%)是其主要成分。血淋巴中存在原血细胞、浆细胞、粒细胞和嗜淋巴细胞4种类型的血细胞。在不同生态型的香薷精油中，血细胞计数明显下降。利用浓度和指定时间对上述细胞数量的减少有显著影响。48 h后，所有生态型的细胞数量最少。NS生态型的血细胞总数下降幅度最大，与8000ppm浓度有关。以KR生态型LC50值最低。基于本研究的结果，从不同生态型的cyminum中分离的精油显示出有希望的管理S. cretica的候选物。
