“…Based on present study, the plant extracts which extracted from P. dioscoridis are promising for the control of T. urticae and both of acetone and methanol were favourable to plant extraction. The present results of P. dioscoridis are in agreement with those documented by Ebadollahi et al (2016), Ebadollahi et al (2017), Fatemikia et al (2017 and Nicolle et al (2016). Example, Pervin and Ayşegül (2016), they evaluated the efficacy of insecticides extracted from three different plants such as Xanthium strumarium L., Tanacetum parthenium L. and Hypericum calycinum L. against green peach aphid (Myzus persicae Sulzer) and found the extracts showed nymphal mortality of 89%, 88% and 57%, respectively at the highest concentration (12%).…”

Senna septemtrionalis (Arsenic bush) Fabaceae and pulchea dioscoridis (pluchea) Asteraceae were collected from farm of faculty of Agriculture, Al-Azhar University, Assiut, Egypt during flowering stages. The extracts obtained from S. septemtrionalis and P. dioscoridis were tested against two-spotted spider mite Tetranychus urticae Koch as acaricidal. Bioassay experiments were carried out under laboratory and field conditions using two different solvents (Acetone and Methanol) by direct leaf spaying. The amount of plant extracts applied at laboratory condition were 1, 2, 3, 4 and 5% concentrations at 27±2°C temperatures and 65±5% relative humidity (RH.) on adult females and eggs of T. urticae. The concentration applied at the field was 4% concentration and dimethyl salphoccied (damson) was used by rate 0.1% as a solvent. The results revealed that, the concentration 4 and 5% gave high mortality than the low concentrations for all solvents. The extracts obtained from P. dioscoridis plant were the highest effective on eggs (67.72% at concentration 5%), adult females (86.51% for acetone and 82.02% for methanol after three days and at concentration 5% under laboratory conditions) and population of T. urticae (71.81 % for acetone and 76.82% for methanol after one week at concentration 4% under field conditions). When, S. septemtrionalis extracted by acetone as solvent gave high results at concentrations 2, 3, 4 and 5% after three days from spraying, while when extracted by methanol was effective only at 4 and 5% concentrations, both plants recorded highly reduction percentages after one week when applied on Cucumis sativus (Cucurbitaceae) cucumber under field condition at concentration 4%. Whereas, the P. dioscoridis extracts were the best. The acetone was the best solvent for both plants.

In recent years, there has been a growing interest in the screening of natural active ingredients from Eucalyptus essential oils because of their evident importance in practical utility and their undeniable therapeutic properties. Based on this, the aim of the present study was to investigate the chemical profile of the essential oils of the trunk bark of Eucalyptus torquata Luehm. (ETEO), and E. salmonophloia F. Muell. (ESEO), growing in Tunisia. The in vitro cytotoxic properties of the extracted EOs were also evaluated against two human cancer cell lines: breast carcinoma cell lines MDA‐MB‐231 and colorectal cancer cell lines SW620. The analysis by gas chromatography coupled with mass spectrometry (GC/MS) led to the identification of 32 compounds from the ETEO, with the dominant constituents being the monoterpenes trans‐myrtanol (73.4 %) and myrtenol (4.7 %), and the apocarotene (E)‐β‐ionone (3.9 %). In the case of ESEO, 29 compounds were identified with trans‐myrtanol (25.0 %), decanoic acid (22.1 %), nonanoic acid (9.8 %), γ‐elemene (6.5 %), γ‐maaliene (5.5 %), and α‐terpineol (5.3 %) as the main components. The cytotoxicity of EOs against the two chosen cell lines was tested using Crystal Violet Staining (CVS) assay and 5‐fluorouracil as a reference drug. The two EOs exhibited a significant dose‐dependent inhibition against the viability of the used cell lines. Their inhibitory effects were particularly observed towards SW620 colon carcinoma cells with IC50 values of 26.71±1.22 and 22.21±0.85 μg/mL, respectively, indicating that both oils were more cytotoxic for SW620 cells compared to MDA‐MB‐231 one.

“…Although a precise EO mode of action is still missing, there is proof that the chemically various ingredients of EOs present a wide range of activities, linked chiefly to arthropod nervous systems and detoxification strategies. There is proof that in TSSM, EO may perhaps interact with distinctive molecular targets, i.e., tyramine and octopamine receptors, the GABA system (modification of ionic channels), and the cholinergic system (reserve of acetylcholine esterase), as well as with diverse enzymes, e.g., Cyt P450 monooxygenase, phosphatases, and glutathione-S-transferase [ 40 , 41 , 42 , 43 , 44 ]. One more anticipated mode of action is an intervention with pheromone creation, therefore influencing behavior and reproduction, and interfering with the juvenile hormones’ assimilation as well asecdysones regulating growth and development [ 45 ].…”

Eggplant is repeatedly attacked by numerous pests, particularly two-spotted spider mite (TSSM), which considerably decline plant productivity. Synthetic acaricides are frequently applied for controlling TSSM, resulting in environmental pollution. The utilization of rational novel substances which repel or prevent TSSM establishment represents a sustainable eco-friendly to reduce the utilization of agrochemicals. A greenhouse investigation was done for assessing the bio-acaricidal activity of mustard (Brassica juncea L.) fixed oil (MFO), jasmine (Jasminum grandiflorum L.) essential oil (JEO), or lavender (Lavandula angustifolia L.) essential oil (LEO), and their influences on eggplant growth and productivity. The results demonstrated that JEO represents the most acaricidal properties against TSSM followed by MFO and/or LEO compared to control. Spraying with natural oils significantly improved eggplant growth, i.e., plant height, number of leaves, and branches/plant, in addition to the leaf area and relative leaf dry mass of the 3rd–5th upper leaves. The JEO had the strongest positive effect compared with other oils or control. Additionally, Natural oils application significantly increased photosynthetic pigment, chlorophyll a:b ratio, and nitrogen, phosphorus, potassium, ascorbic acid, and phenols. The application of oils increased yield and its quality. In this study, JEO (2.5 mL/l) is shown to be extremely promising for the progress of new eco-friendly acaricides, improving plant growth and increasing eggplant yield.
