“…The comparative assessment of the effect of areki (an alcoholic extract of cereal grains in Ethiopia comparable to ethanol produced in a factory) and a commercial acaricide against nymphs and adult ticks on cattle showed that areki was effective as an ethno-veterinary acaricide. Similar results reported from other countries such as in Benin (Dougnon et al 2014;Adehan et al 2016;Anagew et al 2017;Ravindran et al 2017). Pesticides of plant origin work in various ways against ticks.…”

Ticks are a major group of ectoparasites of livestock. A study was conducted to determine the efficacy of locally brewed alcoholic beverage (areki) against ticks on cattle. A sample of 285 cattle owners were purposively selected from the study area. Experiment 1 was a spray of the test materials on affected body parts of animals (150 ml per animal). Treatments include untreated (negative control), areki, and commercial acaricide (positive control). Before spray, each animal was inspected for tick infestation, and the number, growth stage of the ticks was recorded including risk factors (age, sex, health status, feed status, size). Experiment 2 was a toxicity bioassay test of ticks, with four dilution levels with water, i.e., 100%, 50%, 25% and 0% areki by volume. In experiment 1, areki and the commercial acaricide were equally effective. Significantly more live ticks were found on the control and more dead ticks on acaricide and areki. All dilutions were effective in the toxicity bioassay test. In contrast to dead ticks, live tick numbers after spray did not vary with respect to animal health status, body size, sex, breed type, feed supply, and residence (rural and urban). According to the regression analysis, some of the study sites, type of breeds, feed supply, health status of the animal, and spray treatments played significant role in the mortality of ticks (encouraging or discouraging mortality). In general, the current study showed that areki was a promising product for the management of ticks on cattle in Woldia area of Ethiopia.

“…Además, argumentan que tiene efecto alelopático que inhibe germinación y crecimiento de otras especies y presenta asociación con micorrizas arbusculares, lo que le brinda ventajas para su establecimiento. Hacia el norte del departamento, en el municipio Sitio Nuevo, las especies predominantes son Cynodon nlemfuensis (tolerante a inundaciones) y Echinochloa polystachya (presente en zonas pantanosas u orillas de ríos y complejos cenagosos) coincidiendo con la descripción de Díaz-Céspedes et al (2020) quienes afirman que las mejores repuestas en productividad se presentan en zonas húmedas y se comporta bien en condiciones de inundación. Así mismo, se encontró gramíneas que crecen de forma natural, donde sobresalen Bothriochloa pertusa como una especie invasora en el cultivo de banano y Dichanthium aristatum (Quintero-Pertúz et al, 2020).…”

El objetivo principal de esta investigación fue identificar especies con potencial para incorporarse a sistemas agroforestales en 63 unidades productivas de ocho municipios del departamento del Magdalena (Colombia). Mediante recorridos en campo y el apoyo de los productores, se realizó el reconocimiento de la composición de especies vegetales presentes en los sistemas productivos, seguido de su identificación empleando claves taxonómicas y así, obtener el inventario de las mismas, el hábito de crecimiento y los usos más comunes. Los resultados reportaron 122 especies, de las cuales el 66 % son árboles, el 28 % hierbas terrestres y el 6 % arbustos. El 81 % de las especies sirven para sombra, cercas vivas, forrajes, medicinales, ornamentales y protectoras de fuentes de agua, mientras que 35 % son maderables y 29 % forrajeras. Se concluye que las especies seleccionadas presentan características deseables para sistemas agroforestales en el trópico seco.

“…The role of secondary metabolites of plants such as phenols, flavonoids, terpenoids, alkaloids, essential oils, quinones, tannins, saponins and sterols in eliciting defense against pests is well known. The extracts of many plants with promising acaricidal properties were reported from our laboratory too [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. In addition to their direct acaricidal activity due to neurotoxicity, many herbal extracts produced accelerated degeneration of salivary glandular tissue and changes in the morphophysiology of reproductive organs in ticks [ 19 , 20 ].…”

Modulation of the PGE2-Mediated Pathway in the Eclosion Blocking Effect of Flumethrin and Terpenoid Subfraction Isolated from Artemesia nilagirica in Rhipicephalus annulatus

et al. 2021

Prostaglandins are a group of important cell-signaling molecules involved in the regulation of ovarian maturation, oocyte development, egg laying and associated behaviors in invertebrates. However, the presence of prostaglandin E2 (PGE2), the key enzymes for PGE2 biosynthesis and its interference by drugs were not investigated previously in the ovary of ticks. The present study was undertaken to assess the modulation of the PGE2-mediated pathway in the eclosion blocking effect of flumethrin and terpenoid subfraction isolated from Artemisia nilagirica in Rhipicephalus annulatus ticks. The acaricidal activities and chemical profiling of the terpenoid subfraction were performed. The localization of the cyclooxygenase1 (COX1) and prostaglandin E synthase (PGES) enzymes and the quantification of PGE2 in the ovaries of the ticks treated with methanol (control), flumethrin and terpenoid subfraction were also undertaken. In addition, the vitellogenin concentration in hemolymph was also assayed. Both flumethrin and the terpenoid subfraction of A. nilagirica elicited a concentration-dependent inhibition of fecundity and blocking of hatching of the eggs. The COX1 could not be detected in the ovaries of treated and control ticks, while there was no significant difference observed in the concentration of vitellogenin (Vg) in them. The presence of PGES in the oocytes of control ticks was confirmed while the immunoreactivities against PGES were absent in the vitellogenic oocytes of ticks treated with flumethrin and terpenoid subfraction. The levels of PGE2 were below the detection limit in the ovaries of the flumethrin-treated ticks, while it was significantly lower in the ovaries of the terpenoid subfraction-treated ticks. Hence, the prostaglandin E synthase and PGE2 were identified as very important mediators for the signaling pathway for ovarian maturation and oviposition in ticks. In addition, the key enzyme for prostaglandin biosynthesis, PGES and the receptors for PGE2 can be exploited as potential drug targets for tick control. The detection of PGES by immunohistochemistry and quantification of PGE2 by LC-MSMS can be employed as valuable tools for screening newer compounds for their eclosion blocking acaricidal effects.
