Resumen
Limitation the number of ixodes ticks is one of the most important tasks of modern science and requires the search for new, highly effective and environmentally hazardous acaricides, so our experiment was aimed at identifying acaricidal properties of essential oils and their individual active components in the population of ixodes ticks in Zaporizhzhia region. The study of acaricidal properties of essential oils was performed in the laboratory conditions. Tampons with wool were soaked in various concentrations of 0.5%, 1%, 3%, 5% and 10% aqueous emulsion of essential oils such as Caryophyllus floris aetheroleum and Limonis aetheroleum, and essential oils of Thymus serpyllum L., Рinus sylvestris L., Salvia officinalis L., Mentha x piperita L. and Eucalyptus viminalis Labill. The essential oils had a significant effect on the lifespan of adult ticks. The results showed the acaricidal effect of Thymus serpyllum essential oils. When searching the acaricidal and repellent properties of individual essential oils components thymole, menthol and citral showed the high activity as acaricides. In the same time, eugenol and borneol proved the effectiveness as repellent. Our research schowed that essential oils are promising as alternative methods of controlling the number of Ixodes ticks in areas where there are conditions for infection with tick infections.

Resumen
The honey bee (Apis mellifera) faces a significant threat from Varroa destructor, causing the losses of millions of colonies worldwide. While synthetic acaricides are widely used to control Varroa infestations, excessive application has led to resistant strains and poses side effects on the host. Consequently, there is an urgent need for a new acaricide that is both effective and affordable, yet safe to use on bees. One potential source of these acaricides is essential oils (EOs) and their constituents. This study evaluated the acaricidal properties of four essential oils (Eucalyptus globulus, Rosemary officinalis, Trachyspermum ammi (Ethiopian and Indian varieties), their constituents and mixture of constituents against V. destructor through the complete exposure method. Our finding showed that a 1:1 mixture of thymol and carvacrol (4 h-LC50 = 42 μg/mL), thymol (4 h-LC50 = 71 μg/mL), and T. ammi oil (4 h-LC50 = 81–98 μg/mL) were the most toxic test samples against V. destructor. Honey bee behavior and selectivity were also assessed with one additional EO Thymus schimperi, indicating that T. schimperi, T. ammi, and their components were selective and did not affect the learning and memory of bees. In conclusion, the thymol and carvacrol (1:1) mixture was shown to be a promising replacement for synthetic acaricides, being three times more toxic than a commercial acaricide, fluvalinate (4 h-LC50 = 143 μg/mL).

Resumen
The evolution of resistance of Rhipicephalus (Boophilus) microplus to synthetic acaricides has given rise to the need for new scientific investigations on alternative ways to control this tick. In this regard, various studies on plants have been developed in an attempt to find extracts with acaricidal properties. Evaluations on plant extracts for controlling R. (B.) microplus have grown intensely over the last decade. There are many advantages from using plant extracts: for example, they can be used in organic cattle farming or even replace synthetic acaricides and they are associated with lower environmental and food contamination, slower development of resistance and lower toxicity to animals and humans. In vitro studies on plant extracts have shown promising results, but most of these extracts have not been tested on animals to validate their use. Difficulties in preparing proper formulations, differences in the chemical composition of plants of the same species due to extrinsic and intrinsic factors and sparse information on active acaricide compounds are hindrances that need to be addressed in order to enable progress within this scientific field.

Resumen
Mites have been a persistent infectious disease affecting both humans and animals since ancient times. In veterinary clinics, the primary approach for treating and managing mite infestations has long been the use of chemical acaricides. However, the widespread use of these chemicals has resulted in significant problems, including drug resistance, drug residues, and environmental pollution, limiting their effectiveness. To address these challenges, researchers have shifted their focus towards natural products that have shown promise both in the laboratory and real-world settings against mite infestations. Natural products have a wide variety of chemical structures and biological activities, including acaricidal properties. This article offers a comprehensive review of the acaricidal capabilities and mechanisms of action of natural products like plant extracts, natural compounds, algae, and microbial metabolites against common animal mites.

Resumen
Chemical characterization of the bulbs of Drimia pancration was conducted to isolate four steroidal saponins (1–4). Earlier, we focused on the structural elucidation of compounds 1–3. Herein, by means of 1H-NMR, 13C-NMR, Nuclear Overhauser Effects (NOE), and 2D-NMR spectra, the full stereochemical structure of 4 is reported, and all the 1H and 13C signals are assigned. Compounds 1–4 were tested for their acaricidal properties against the two-spotted spider mite Tetranychus urticae. Our results showed excellent activity of compound 1, with an LD50 (µg/cm2) of 0.29 and a LD90 (µg/cm2) of 0.96, whereas compounds 2, 3, and 4 showed moderate activity. Furthermore, the acaricidal and cytotoxic properties of the crude extract were also investigated. Of note, after 96 h of exposure, the acaricidal activity of compound 1 was higher than that of the positive control, hexythiazox. Indeed, for compound 1, LD50 and LD90 were 0.29 and 0.96 µg/cm2, respectively, while hexythiazox LD50(90) was 18.7 (132.5) µg/cm2. Additionally, D. pancration extract, after 72 h, induced a high cytotoxic effect in HaCaT and THP-1 cell lines, with an IC50 of 7.37 ± 0.5 µg/mL and 3.50 ± 0.15 µg/mL, respectively. Overall, D. pancration can be considered as a green source of novel acaricides effective against mites of agricultural importance, such as T. urticae, pending proper field validation and the assessment of non-target effects on other invertebrate species.

Resumen
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.

Resumen
This research was aimed at evaluating in vitro and in vivo effects of lemongrass (Cymbopogon flexuosus Stapf.) oil, citronella (Cymbopogon winterianus Jowitt) oil and eucalyptus (Corymbia citriodora) oil on cattle ticks (Rhipicephalus (Boophilus) microplus), each of which corresponds to an essential oil experiment. Negative control group end eight concentrations of lemongrass oil, citronella oil and eucalyptus oil (0.5; 1; 2; 5; 10; 20; 50; 100%), were used on in vitro trials with engorged female ticks. The efficacy control ticks was 0; 20; 39; 99.5; 100; 100; 100; 100 and 100%, for lemongrass oil, of 0; 34.5; 43; 48; 82; 99; 99; 100 and 100%, for citronella oil and 0; 30.5; 75.5; 91; 100; 100; 100; 100 and 100%, of oil, respectively. On in vivo trial eighteen Holstein cows were allocated to three groups for each treatment (negative control, essential oil - level estimated by regression analysis, accounting for 95% efficacy of control ticks on in vitro trial and amitraz at 0.025%). Engorged female ticks were counted before (mean of days -3, -2, -1) and after treatment (1, 2, 3, 5, 7, 10, 14, 21 days). Twenty one days after application of the products, the efficacy on control ticks was 0; 54 (lemongrass oil at 2%) and 74.5%; of 0; 91.3 (citronella oil at 8.6%) and 60%; and 0; 96.4 (eucalyptus oil at 3.5%) and 69%, respectively for in vivo treatments. On the 1st and 2nd milked after treatments, physiologic variables were evaluate and milk samples were collected to evaluate organoleptic properties in milk and yoghurt (negative control x phytotherapic treatment). Similar results were found with sensorial acceptance test of milk and physiologic variables, in the three in vivo experiments.

Resumen
The objective of the study was to explore IK used to control ticks and associated diseases. A structured questionnaire (n = 250) were administered randomly to collect IK amongst the households active in goat production. Challenges on the use of ethno veterinary plants were also captured using focus group discussions. There was an association between goat ownership and gender, males used IK (70%) more than their female counterparts. Ticks were ranked as the major ectoparasites affecting goat productivity. Amongst ticks, Amblyomma species were ranked as the most important. Cissus quadrangularis. Lin (32%), Gomphocarpus physocarpus E. Mey (27%) and Portulaca pilosa L. (25%) plants had the highest FL values for their use to control ticks. Four plant species were identified to treat goats against tick-borne diseases. Pittosporum viridiflorum Sims and Boophane disticha were reported to treat heart water. Aloe marlothii A.Berger and Erythrophleum africanum (Benth.) Harms plants cure anaplasmosis. Livestock farmers hold substantial knowledge of ethno-veterinary plants to control ticks and their associated challenges. More research is required to affirm the acaricidal properties claimed to promote and optimize sustainable use of these medicinal plants.

Resumen
Abstract With many drug molecules, the replacement of a carbon atom with a silicon atom is known to lead to a lowering of toxicity and a prolonged manifestation of the physiological effect. ‘Torque’, an acaricide developed by Shell in the 1970s, has the formula [(PhMe CCH)3Sn]2O. This acaricide has been derivatized to the (PhMe ECH)3SnX (X = Cl, ½O; E = C, Si) compounds, whose biological properties show that the silyl analogue of Torque was equally effective. By using [(PhMe SiCH)3Sn]2O (silyl-Torque) and (PhMe SiCH hSnCl as starting reagents, we have synthesized a series of tris(phenyldimethylsilylmethyl)aryloxy- and aklyloxyacetates [eqn (47.1)], arylcarboxylates [eqn (47.2)], and dithiophosphates [eqn (47.3)].

Resumen
Aerogels, composed of complex network of interlinked nanostructures, show 50% non-solid volume. Due to their unique properties, they are used as a carrier for active ingredients used to control agricultural pests as well as veterinary medicines. They can also be used as a carrier material for the application of entomopathogenic bacteria and viruses for the biological control of pests. Many aerogel-based formulations of herbicides, insecticides, acaricides, fungicides, bactericides, rodenticides, nematicides, piscicides and molluscicides effectively control the target pests. Practically, aerogels enhance the effectiveness of insecticides by increasing their penetrations. Furthermore, intensive research is required to develop latest aerogel-based pesticides with better utilization under effective integrated pest management programs in agriculture.

Resumen
To develop screening methods and identify nematocidal effects of anthelmintics in vitro, we used the methodology we developed [2]. Our purpose was to find nematocidal properties among well-known pesticides: anthelmintics, acaricides, insecticides, molluscicides, and drugs used in plant protection, veterinary medicine and in medicine. In case nematocidal properties are detected, they can be used in practice to control phytohelminths. In our research, this is a selection to detect nematocidal substances for screening objects. The screening objects are nematodes of different ecological groups, namely Caenorhabditis elegans, Turbatrix aceti, and Ditylenchus destructor. The nematicidity assessment was carried out by comparison with the control and reference options. As a result of the studies, references were determined for in vitro screening methods for nematocidal activity of anthelmintics. Phytoverm, CE (Aversectin C (2g/L)) was taken as a reference. Nematode mortality was determined by the Schneider-Orelli’s formula. Of the tested anthelmintics, nematocidal effect was detected in Albendazole, Decaris, Vermox, Levamisole, Tetramisole, and Iversan. The result of the studies for nematicidity of pesticides and anthelmintics found that the in vitro screening method developed by us was effective in identifying substances with nematocidal properties.
