“…Then, for M. piperita, it's chemical composition shows the presence of linalool (51.57%) and its acetate (35.35%) (Table A .5). These compounds are known for their insecticidal activities (Mejdoub et al, 2019) which explained the mortality results obtained in our study.…”

Morocco's prickly pear has high economic value. However, it’s infected by the cochineal Dactylopius opuntiae, causing massive losses. Thus, the present work aims to study insecticidal effect of bioactive natural extracts. Essential oils and hydrosols of oregano (Origanum vulgare), thyme (Thymus vulgaris), pennyroyal (Mentha pulegium) and peppermint (Mentha piperita) were tested. Two concentrations were used for essential oils (1.5% and 3%) and for hydrosols (100% and 75%) with contact and fumigant application. Mortality rate was determined after 24h of treatment. Highest values were recorded at 3% E.O concentration with contact assay comparing to fumigation. As it’s EO (99.44%), O. vulgare hydrosol has significant insecticidal activity reaching 80% of mortality rate. Chemical composition of essential oils using Gas Chromatography coupled to Mass Spectrometry (GC/MS) was studied. Bioactive compounds include carvacrol and m-cymene (O. vulgare and T. vulgaris), pulegone and l-menthone (M. pulegium) and Linalool and linalyl acetate (M. piperita). Data obtained relieved the importance of these plants as source of natural bioactive compounds against D. opuntiae.

Toxics or Lures? Biological and Behavioral Effects of Plant Essential Oils on Tephritidae Fruit Flies

et al. 2021

View full text Add to dashboard Cite

The family Tephritidae (Diptera) includes species that are highly invasive and harmful to crops. Due to globalization, international trade, and human displacement, their spread is continuously increasing. Unfortunately, the control of tephritid flies is still closely linked to the use of synthetic insecticides, which are responsible for detrimental effects on the environment and human health. Recently, research is looking for alternative and more eco-friendly tools to be adopted in Integrated Pest Management (IPM) programs. In this regard, essential oils (EOs) and their main compounds represent a promising alternative to chemical insecticides. EOs are made up of phytoconstituents formed from the secondary metabolism of many plants and can act as attractants or toxics, depending on the dose. Because of this unique characteristic, EOs and their main constituents are promising tools that can be used both in Sterile Insect Technique (SIT) programs and in the “lure and kill” technique, exploiting the attractiveness of the product in the former case and its toxicity in the latter. In this article, current knowledge on the biological and behavioral effects of EOs and their main constituents on tephritid fruit flies is reviewed, mainly focusing on species belonging to the Anastrepha, Bactrocera, Ceratitis, and Zeugodacus genera. The mechanisms of action of EOs, their real-world applications, and challenges related to their use in IPM are critically discussed.

“…Their antimicrobial activity increases the shelf life of foods [6]. Some essential oils are antifungal agents useful for food preservation [7][8][9][10][11][12][13][14][15][16]. In addition, these volatile molecules are used in agriculture as soil correctors (redox couple) due to their targeted action and biodegradable nature [17,18].…”

The chemical compositions of eleven wild species of aromatic and medicinal plants indigenous to Algeria, including Thymus, Mentha, Rosmarinus, Lavandula, and Eucalyptus, were analyzed. The identification of the chemical composition of each oil was conducted using GC-FID and GC-MS capillary gas chromatography. The study investigated the chemical variability of the essential oils based on several parameters. These included the impact of the vegetative cycle on oil composition, variations among subspecies of the same species, variations among species within the same genus, the influence of environmental factors on composition variations within a species, chemo typing, and the genetic factors (such as hybridization) contributing to chemical variability. The concepts of chemotaxonomy, chemotype, and chemical markers were examined to understand their limitations and emphasize the importance of regulating the use of essential oils derived from wild plants. The study advocates for an approach that involves the domestication of wild plants and screening their chemical compositions according to more specific standards for each commercially available oil. Lastly, the nutritional implications and the variability of nutritional impact based on the chemical composition of the essential oils will be discussed.
