The advancement of the livestock farming in sub-Saharan Africa is restricted by tick infestation. With conventional pesticides posing a threat to human and the environment, natural products are alternative anti-tick source. This study characterized the essential oils from Tithonia diversifolia, Lavandula angustifolia and Cymbopogon citratus leaves by GC-MS and, for acaricidal and repellence of R. appendiculatus. GC-MS analysis detected various chemical compounds, some of the isolated compounds have anti-tick properties. The repellence of T. diversifolia essential oil at 5% v/v was the weakest against adult ticks. All essential oils at 15% v/v paralysed nymph after 20 mins, with C. citratus after 24 h causing high mortality of nymph and adult ticks. Exposure to L. angustifolia did not achieve 50% mortality after 24 h. All essential oils caused complete inhibition of moulting of engorged larvae. The study demonstrated that the essential oils of the ethno-veterinary plants may be a source of anti-ticks agents.

AbstractBiocompounds are promising tools with the potential to control pathogenic microorganisms. The medicinal plant species Ocotea odorifera, Ocotea puberula and Cinnamodendron dinisii, distributed along Brazilian biomes, are sources of chemical compounds of biological interest. This study aimed to evaluate the antifungal activity of the essential oils of O. odorifera, O. puberula and C. dinisii essential oils upon the mycotoxin producers Alternaria alternata, Aspergillus flavus and Penicillium crustosum. The essential oils where characterized by gas chromatography coupled to mass spectrometer (CG-MS). The majority compounds identified were: safrol (39.23%) and camphor (31.54%) in O. odorifera, Beta-caryophyllene (25.01%) and spathulenol (17.74%) in O. puberula, and bicyclogermacrene (23.19%) and spathulenol (20.21%) in C. dinisii. The Minimal Inhibitory Concentration (MIC) of antifungal activity considered diameters higher than 10 mm after 72 h of incubation at 30 ºC. A. alternata presented higher resistance to O. odorifera and C. dinisii oils. The inhibitory effect of O. odorifera on A. flavus showed stabilization at oils concentrations between 50% and 80%, increasing at 90% and 100% (pure oil) treatments. We observed that the essential oils of O. odorifera and C. dinisii have potential in the control of the analyzed fungi species. The essential oil of O. odorifera presented a better activity in all the assays, which can be related to the presence of safrole and phenylpropenes, compounds with known antifungal activity.

Electrophysiological responses based on electroantennographic detection (GC-EAD) and electroantennography (EAG) analysis of Naupactus bipes beetles (Germar, 1824) (Coleoptera: Curculionidae: Brachycerinae) were used to test volatile oils of Piper gaudichaudianum, P. regnellii and P. hispidum. In the EAG experiments, female and male beetles showed significant EAG response to the three volatile oils of Piper species, with the females’ responses slightly higher than the males’. The experiments with GC-EAD revealed that some terpenoids (namely, α-pinene, β-pinene, myrcene, α-copaene and germacrene) present in the leaf essential oils of the Piper species are perceptible to female and male beetles.
