Effect of the Essential Oil of Clausena anisata (Rutaceae) and Palm Kernel Vegetable Oil on Engorged Females of Three Species of Ixodidae Cattle Ticks

“…Indeed, the death of A. variegatum engorged females has been dose-dependent since they survive and lay eggs when the essential oil of C. anisata dose drops. These results were observed by Pazinato et al (2016) and dos Santos, Vogel and Monteiro (2012) who additionally note the inhibition of oviposition and hatching as a function of dose. The decrease in toxicity of the essential oil of C. anisata is caused by the decrease in the amount of essential oil in the various dilutions on the one hand; this greatly reduces cuticle alteration by the essential oil (Chiasson & Beloin, 2007; Chiasson et al, 2004 a and b) and consequently slows down the diffusion of the essential oil, which probably can no longer effectively damage the cuticle.…”

“…Essential oil of C. anisata would have the same properties and was able to partially or totally inhibit pré-oviposition, oviposition, eggs laid, hatching and therefore, reduce A. variegatum reproductive efficiency. Several authors (Pazinato et al, 2016;Yessinou et al, 2016) have made the same observations with most other essential oil from plants and have highlighted that their effectiveness is due to monoterpenoids which are the major compounds. This has been confirmed by Gazim et al (2011) who showed that monoterpenoids compounds of essential oils had effects on the growth, moulting, fecundity, and development of insects and mites.…”

“…(B. ) Nowadays, the use of plant extracts with acaricide properties, as new control methods, is being explored to cope with tick threats (Pazinato et al, 2016;Yessinou et al, 2016;Chagas et al, 2014), although their essential oils are volatile.…”

Preventing tick attachment to dogs using essential oils

“…These metabolites are volatile molecules of low molecular weight and usually contain two or three major terpene or terpenoid components, which constitute up to 30% of the oil (Bakkalai et al, 2008). There is a growing body of evidence indicating that they possess varying mechanisms of action against arthropods; they have been shown to inhibit feeding and the synthesis of chitin, decrease growth, development or reproduction, and affect behaviour including acting as repellents (Pazinato et al, 2016;Rosado-Aguilar et al, 2017). The efficacy of essential oils is often attributed to the oil's major component(s); however, there is also evidence that the various oil components may work in synergy (Nerio et al, 2010).…”

Conservation des extraits aqueux de feuilles de neem, d’hyptis et de papayer et efficacite contre les ravageurs du niebe au Benin

“…Les crises alimentaires marquées ces dernières années par la famine en Afrique, entraînent le développement des technologies endogènes pour répondre aux besoins alimentaires de la population. La lutte agrobiologique contre les ravageurs des plantes constitue l'un des facteurs de réduction de la famine et différentes technologies ont été mises au point dans le monde (Giglioti et al, 2011, Pazinato et al, 2016, dans la sous-région ouestafricaine (Kwaifai et al, 2015 ;Mamuda et al, 2016) et au Bénin (Affokpon et al, 2017) pour améliorer son efficacité. Des études ont montré l'efficacité des dérivés du neem sur les ravageurs de maïs, du sorgho et du niébé (Mukendi et al, 2014;Tamgno et Ngamo Tinkeu, 2014).…”
