Fumigant toxicity of tarragon (Artemisia dracunculus L.) and dill (Anethum graveolens L.) essential oils on different life stages of Trialeurodes vaporariorum (Westwood)

Abstract

Trialeurodes vaporariorum (Westwood) is a polyphagous species. This pest is now well-established in the greenhouse ecosystem and is an economically important pest of horticultural and ornamental crops. The fumigants toxicity of tarragon (Artemisia dracunculus L.) and dill (Anethum graveolens L.) essential oils on the life stages of Trialeurodes vaporariorum were investigated under laboratory conditions. Plants essence samples were obtained from the aerial parts of the plant by using Clevenger device. In this study, six concentrations (5 concentrations and one control) were used to evaluate LC 50 level and five time periods were used for LT 50. The LC 50 values for Artemisia dracunculus and Anethum graveolens at 24 h after treatment of the eggs, nymphs and

Effects of Artemisia dracunculus L. Water Extracts on Selected Pests and Aphid Predator Coccinella septempunctata L.

“…Research by Metspalu et al [13] showed that the extract of this plant prepared with the use of hot water caused 50% mortality of young Colorado potato beetle (Leptinotarsa decemlineata Say) larvae. The essential oils of tarragon have been shown to be effective in combating storage pests (Sitophilus granarius L. [14], Callosobrochus maculatus F. [15,16]), aphids (Aphis gossypii Glover), thrips (Thrips tabaci L.) [17,18], greenhouse whitefly (Trialeurodes vaporariorum Westwood) [19], and the Colorado potato beetle [20]) as well as sanitary pests such as Calliphora vomitoria L. [21], Blatella germanica L. [22], and Anopheles stephensi Liston [23]. The effectiveness of plant extracts depends on, among other things, the method of their preparation, and particularly the solvent used.…”

Studies of the Tarragon Essential Oil Effects on the Characteristics of Doped Hydroxyapatite/Chitosan Biocomposites

“…Generally, biological properties of the essential oils are determined by their major chemical constituents [92,93]. In the case of our study, the essential oil used to prepare ZnHAChT was French tarragon (Artemisia dracunculus L.) and the major chemical constituents of tarragon essential oil were reported to be estragole, sabinene, methyleugenol, trans-anethole, limonene, terpinolene,β-ocimene, terpinen-4-ol, α-ocimene and elemicin [19,[94][95][96]. Estragole, also known as methyl chavicol, has been reported to exhibit a broad spectrum of antifungal activities against Mucor mucedo, Aspergillus niger, Botryodiplodia theobromae, Fusarium solani, Candida albicans, Rhizopus solani and Microsporum gypseum which were observed to be achieved by causing the disruption of fungal membrane [97].…”

Phytochemical Study on the Essential Oils of Tarragon (Аrtemisia dracunculus L.) Growing in Tajikistan and Its Comparison With the Essential Oil of the Species in the Rest of the World

“…11,16,24,26 It has been found in high concentrations in the essential oil A. dracunculus growing in Tibet (China, 19.2%), Lithuania (14%-25%), Romania (42.4%), and Kazakhstan (20.2%). 11,16,24,26 Estragole or methyl chavicol was reported as one of the principal components in many tarragon essential oils with the range 70%-85% 12,17,20,22,24,29,34,35 and is a key component of French tarragon oil (>80%). 4 A hierarchical cluster analysis of А. dracunculus essential oils on the global phytogeographic origin, based on 30 essential oil components and 105 samples (globally) of this species, indicated the existence of its 7 major chemotypes: (1) (E)-β-ocimene/(Z)-βocimene chemotype, (2) an α-terpinene chemotype, (3) a capillene chemotype, (4) a methyl eugenol chemotype, (5) a mixed chemotype, (6) a (Z)-artemidin (3-(1Z-butenyl)-isocoumarin) chemotype, and (7) an estragole (methyl chavicol) chemotype (see Supplemental Material).…”
