“…According to Fernandez et al [ 132 ] α- trans -bergamotene was the major component of the EO of the fruits of Garcinia gardneriana and showed toxicity against Aedes aegyptus mosquito larvae. Vinturelle et al [ 133 ] reported that the EO of Copaifera officinalis contained α- trans -bergamotene as one of the compounds with the highest content and caused 84.60% mortality in engorged females of the tick Rhipicephalus microplus. The authors attributed this toxicity to the presence of sesquiterpenes, including α- trans -bergamotene, in the chemical profile of the EO.…”

The essential oils (EOs) of Myrciaria floribunda (Mflo) and Myrcia sylvatica (Msyl) (Myrtaceae) were obtained by hydrodistillation. The analysis of volatile constituents was performed by GC/MS. Preliminary toxicity was assessed on Artemia salina Leach. The antioxidant capacity was measured by the ABTS•+ and DPPH• radical inhibitory activities. The results indicate that the Mflo EO had the highest yield (1.02%), and its chemical profile was characterized by high levels of hydrocarbon (65.83%) and oxygenated (25.74%) monoterpenes, especially 1,8-cineole (23.30%), terpinolene (22.23%) and α-phellandrene (22.19%). Regarding the Msyl EO, only hydrocarbon (51.60%) and oxygenated (46.52%) sesquiterpenes were identified in the sample, with (Z)-α-trans-bergamotene (24.57%), α-sinensal (13.44%), and (Z)-α-bisabolene (8.33%) at higher levels. The EO of Mflo exhibited moderate toxicity against A. salina (LC50 = 82.96 ± 5.20 µg.mL−1), while the EO of Msyl was classified as highly toxic (LC50 = 2.74 ± 0.50 µg.mL−1). In addition, relative to Trolox, the EOs of Mflo and Msyl showed significant inhibitory effects (p < 0.0001) against the DPPH• radical. This study contributes to the expansion of chemical and biological knowledge on the EOs of Myrtaceae species from the Amazon region.

“…In this work, EOAp inhibited the oviposition more than 80%. Ribeiro et al [37] found that EO from Hesperozygis ringens (which has a content of 86.0% oxygenated monoterpene Pulegone), inhibited egg laying by 76.4% at concentration of 5%; Piper nigrum and Pelargonium roseum EOs at identical concentration inhibited oviposition by 83% and 87.5%, respectively [35]. Those results suggest that sub-lethal doses of essential oils may have an effect on tick fecundity.…”

“…An acaricide that kills females before the third day can prevent egg-laying, disrupting the tick's life cycle [35] because engorged females begin laying eggs on day 3 or 4 after dropping from the host. In this work, none of the EO Ap/Lm killed the female ticks immediately after the treatment; however, all the ticks died around day 4 (±1.69) in 4% EO Ap .…”

Control measures against common cattle tick Rhipicephalus microplus are of the upmost importance because of considerable, deleterious impact on a farm’s economy. Due to resistance phenomena to synthetic acaricides being a constraint in affected farms, the search for plant derivatives as acaricides has increased dramatically in recent years. In this work, essential oils obtained from two Ecuadorian plants, Ambrosia peruviana and Lepechinia mutica (EOAp, EOLm), traditionally used as insecticides in indigenous communities, were studied on larvae and engorged females at the parasitic stages of R. microplus. Larvae and females were treated with five (0.0625, 0.125, 0.25, 0.50 and 1%) and six concentrations (0.125, 0.25, 0.50, 1, 2 and 4%), respectively, of each EOsAp/Lm. A 98–99% larval mortality was achieved with 0.5% of both EOsAp/Lm. EOAp inhibited oviposition and egg hatching up to 82% and 80%, respectively, and had an overall efficacy of 93.12%. Efficacy of EOLm was 72.84%, due to the low influence of EOLm on reproductive parameters. By steam distillation and GC-MS analysis, γ-Curcumene was identified as the main constituent (52.02%) in the EOAp and Shyobunol (10.80%) in EOLm. The results suggest that major components of both essential oils should be further studied as promissory acaricides against R. microplus.

“…Due to the necessity of finding alternative methods for controlling these ectoparasites, research involving plant derivatives has been encouraged and shows promising results. Remarkably, using phytomedicines rich in bioactive compounds with action against different life stages of ticks has gained attention (Banumathi et al, 2017;Vinturelle et al, 2021). For example, Plectranthus amboinicus (Lour.)…”

Chemical acaricides are used as the primary method for controlling Rhipicephalus (Boophilus) microplus. However, the incorrect use of these compounds over the years has led to the emergence of resistant tick populations. This study aimed to evaluate the effectiveness of different combinations of synthetic acaricides and the essential oil of Plectranthus amboinicus on engorged females of R. (B.) microplus. Engorged females were obtained from infested bovines in dairy farms in the Agreste mesoregion of Pernambuco, Brazil. Five different combinations of commercial synthetic acaricides: I) Chlorpyrifos 30.0g + Cypermethrin 15.0g + Fenthion 15.0g; II) Chlorpyrifos 8.5g + Cypermethrin 15.0g + Ethion 16.0g; III) Deltamethrin 50.0g; IV) Amitraz 12.5g; V) Chlorpyrifos 15.0g + Cypermethrin 25.0g + Piperonyl butoxide 50.0g, and the 1% essential oil of P. amboinicus were used for the Adult Immersion Test. Only the combinations I and V of synthetic acaricides and essential oil showed efficacy over 95%. The findings of this study demonstrate that ticks’ resistant populations are present in the study area, and the essential oil of P. amboinicus is a promising compound for developing products used for tick control. Finally, it is paramount to implement educational activities to improve farmers' awareness of the rational use of acaricides.
