“…Data about the repellency of the components agreed with recent literature. Indeed, citronellol 7% resulted repellent ( Ferreira et al, 2017 ) as well as geraniol 1% ( Khallaayoune et al, 2009 ) and 1,8-cineol ( Pålsson et al, 2008 ), while linalool ( Tabari et al, 2017 ) and linalyl-acetate scored uneffective.…”

Sensitivity of Entomopathogenic Fungi and Bacteria to Plants Secondary Metabolites, for an Alternative Control of Rhipicephalus (Boophilus) microplus in Cattle

et al. 2018

Boophilus (Rhipicephalus) microplus is a one host hard tick widespread in warm climates worldwide, responsible for great economic losses. To avoid resistance in ticks population, induced by the repeated administration of conventional acaricides and/or the presence of residues in the environment in meat and in milk, an alternative approach can be achieved using entomopathogenic microorganisms such as fungi and bacteria, or essential oils (EOs). The aim of the present study was to evaluate the in vitro sensitivity of Beauveria bassiana, Metarhizium anisopliae, Scopulariopsis sp, Bacillus thuringiensis and Proteus mirabilis to Eucalyptus globulus, Lavandula hybrida, Pelargonium graveolens EOs and to their main constituents such as lynalool, linalyl-acetate, geraniol, citronellol and 1,8 cineole. EOs has been chemically characterized by GC-MS. Fungal isolates were tested by a microdilution assay to achieve minimal inhibitory concentration (MIC) of both EOs and main components. The sensitivity of bacteria was evaluated by an agar disk diffusion. The results obtained show the feasibility of an integrate approach for an eco-friendly control of R. microplus by use of both entomopathogenic fungi and P. graveolens EO. L. hybrida could be an interesting alternative when B. bassiana is not employed. Conversely, a combined use of B. thuringiensis and EOs would not be advisable in the integrate control of ticks.

“…The treated filter paper was clipped to one rod, on the other rode, a filter paper was treated with ethanol 70% acted as a negative control. Another, third rode contained a positive control filter paper treated with standard repellent, DEET (N,N-diethyl- 3-methylbenzamide), at concentration of 7.5% [ 24 ]. Nearly 30 larvae of R .…”

Acaricidal activity of Foeniculum vulgare against Rhipicephalus annulatus is mainly dependent on its constituent from trans-anethone

et al. 2021

Globally, the economic losses due to hard ticks infestation and the control of the associated diseases have been calculated at USD $13.9–18.7 billion per year. The economic impact is related to its direct damage to the skins, blood loss, anemia, severe immunological reactions and indirect losses that related to the effects of hemoparasites, cost of treatment for clinical cases and expenses incurred in the control of ticks. The current study evaluated the acaricidal activities of fennel Foeniculum vulgare essential oil and its main components; trans-anethole and fenchone; against R. annulatus. GC–MS analysis revealed that this oil contained 16 components representing 99.9% of the total identified compounds with E-anethole being the predominant component(64.29%), followed by fenchone (9.94%). The fennel oil and trans-anethole showed significant acaricidal activities. The LC50 of the fennel oil was attained at concentrations of 12.96% for adult ticks and 1.75% for tick larvae meanwhile the LC50 of trans-anethole was reached at concentrations of 2.36% for adult tick and 0.56% for tick larvae. On the contrary, fenchone showed no any significant adulticidal activities and its LC50 attained at a concentration of 9.11% for tick larvae. Regarding repellence activities, trans-anethole achieved 100% repellency at the concentration of 10% while fennel showed 86% repellency at the same concentration. Fenchone showed no repellency effect. Treatment of larvae with fennel, trans-anethole, and fenchone LC50 concentrations significantly inhibited the acetylcholinesterase activity. Meanwhile, glutathione s-transferase activity was significantly decreased in fennel treated larvae but no significant effect was found in the larvae of trans-anethole and fenchone groups. These results indicate that the acaricide effect of fennel oil may attributed to its high content of trans-anethole. This was supported by potent adulticidal, larvicidal, and repellency effects of trans-anethole against Rhipeciphalus annulatus tick and therefore it could be included in the list of acaricide of plant origin.

“…The essential oils that are found in plants generally also have a repellent effect, such as thymol (which, in addition to the repellent effect, killed R. microplus larvae) (Novelino et al 2007), eugenol (Zeringóta et al 2013) and an extract from Lippia alba (Lima et al 2016). In addition, methods for detecting natural compounds with repellent activity on R. microplus larvae have been developed and standardized (Chagas and Rabelo 2012;Ferreira et al 2017;Wanzala et al 2014).…”

Pests and Vector-Borne Diseases in the Livestock Industry

View full text Add to dashboard Cite

Worldwide the livestock industry, from small farmers to large industrialized farms, is affected by arthropods and arthropod-borne diseases at various scales, which cause huge losses and are a constraint to socio-economic development. Farmers make considerable efforts to prevent and control pest and disease incidence, often requiring the use of vaccines, if available, drugs and pesticides. Examples of current problems are presented, to set the stage for the detailed and state-of-the-art presentations of specific cases of livestock pests and their associated diseases and modern methods of prevention and control.
