Improving and increasing livestock production system yield requires parasite control, especially ticks, which stifle the emergence of successful breeding units. Effective environmentally friendly and biological parasite control is urgently required. The purpose of this study was to evaluate the effects of the essential oil of Clausena anisata (Rutaceae) and of palm kernel vegetable oil compared to a reference chemical acaricide, flumethrin, on the biological parameters of the engorged females of three major tick species in the Maritime Region of Togo. The topical tests applied consisted respectively of depositing a drop of 75μL and 5μL of the crude extracts and their dilutions on the back of each female of Amblyomma variegatum, Rhipicephalus (Boophilus) decoloratus, and Rhipicephalus (Boophilus) microplus (Ixodida: Ixodidae). Fifteen females and three replicates were tested, incubated at 28 ± 1°C, 85-95% RH, 12: 12 L:D, and were monitored daily. C. anisata caused 100% mortality in all engorged females and its 1/8 dilution destroyed 100% of eggs laid by A. variegatum. Palm kernel vegetable oil caused 100% mortality in female species of the genus Rhipicephalus (B.). Flumethrin was very toxic to ticks. Since Palm kernel vegetable oil has a significant toxicity, the two oils tested can be an alternative control of the studied ticks after additional studies.

The control of tick species that affect animal production is vital for the economic welfare of the cattle industry. This study focused on testing the acaricidal activity of the essential oil from the leaves and stems of Tagetes minuta against several Brazilian tick species, including Rhipicephalus (Boophilus) microplus, Rhipicephalus sanguineus, Amblyomma cajennense and Argas miniatus. The chemical composition of the essential oil was determined by chromatography and spectroscopy analyses, which revealed the presence of monoterpenes. The adult immersion test (AIT) and the larval packet test (LPT) were used to evaluate the efficacy of T. minuta essential oil in tick management at concentrations of 2.5, 5, 10, 20 and 40%. The results demonstrated that the T. minuta essential oil had over 95% efficacy against four species of ticks at a concentration of 20%. These results suggest that the essential oil of T. minuta could be used as an environmentally friendly acaricide.

Background: Tick-borne diseases (TBDs) cause significant losses among livestock and impact the livelihoods of livestock communities worldwide including Somalia. Infections with Babesia and Theileria species are endemic in Somalia yet there is a lack of adequate information on their prevalence. Objective: The present study aimed to assess the prevalence of Cattle Piroplasmosis in three districts of Lower Shabelle Region, Somalia using microscope and to identify the available tick species found in the sampled cattle during the study. Methods: A total of 127 Cattle blood were examined for Piroplasms (Babesia and Theileria) using Microscope during January to February 2020. The available ticks were collected in 70% Ethanol. Results: The overall prevalence of Piroplasmosis was 123/127 (96.9% 95% CI: 92.1-99.1%). About 45 out of 127 (35.4% 95% CI: 27.1-44.1%) samples were positive for either Theileria or Babesia, while 78 out 127 (61.4% 95% CI: 52.4-69.9%) samples were mixed infected with both them. Risk factors like age, body condition, sex, lymphnode enlargement and presence of ticks were found to be insignificantly associated with Babesiosis and Theileriosis. For both infections the mean PCV of infected animals was insignificantly lower than non-infected animals. Six tick species belonging to two genera (Rhipicephalus and Amblyomma) were identified in the investigated cattle, including, R. pulchellus (64.7%), R. (Boophilus) microplus, (2%) R. (Boophilus) decoloratus (2%), R.evertsi, (3.9%) A. gemma (15.7%) and A. lepidum (11.8%). Conclusion: This study revealed a very high prevalence of Piroplasmosis in the study area and co-infections were more common than single infections. Further studies in other areas in the country are recommended.

First Occurrence

This study aims to report the occurrence of parasitism byAmblyomma ovale (Koch, 1844) in dogs in the municipality of Apodi, Rio Grande do Norte, Brazil. Specimens were identified as being one female and two males of A. ovale, besides; the animal was infested by five females of Rhipicephalus(Boophilus) microplus and seven females and three males of R. sanguineus. The finding ofA. ovale confirms results in the literature that these ticks, reported in several species of wild carnivores, can also infect dogs in Brazil. The distribution of this tick species in several Brazilian states has already been confirmed, but this is the first report in the State of Rio Grande do Norte. This finding highlights the risk of the carrying of emerging and re-emerging pathogens to peridomestic hosts are as, either because of the frequency of these ticks in wild environments or the presence of infected wild animals near peridomestic environments, exposing domestic dogs to parasitism byA. ovale ticks and, therefore, to agents potentially carried by this ectoparasite.

ABSTRACT: Brazil has one of the largest commercial cattle herds in the world, which naturally coexist with an enormous number of parasitic species. Southern cattle tick, Rhipicephalus (Boophilus) microplus, is among these species, interfering with animal productivity and causing losses to the beef and dairy cattle sector. The use of chemical acaricides in the control of this mite has resulted in the emergence of resistant populations. In this sense, alternative control measures using plants as sources of botanical acaricides have shown to be effective. Eugenia pyriformis Cambess is a Brazilian plant with antioxidant and antimicrobial activity; however, there are no reports on its acaricidal activity in the literature. The present study aimed to evaluate the acaricidal and larvicidal potential of E. pyriformis leaf essential oil (EO) on southern cattle tick at different stages of the reproductive cycle. E. pyriformis leaves were collected and dried, and had their EO extracted by hydrodistillation (3h) using a modified Clevenger apparatus. Chemical analysis was performed by gas chromatography coupled with mass spectrometry (GC/MS), and 32 compounds belonging to the sesquiterpene class were identified: hydrocarbons (17.98%) and oxygenated forms (81.96%), with spathulenol (43.65%) and caryophyllene oxide (12.17%) as the most common. The EO was evaluated by the Adult Immersion Test at the concentrations (500.00 to 3.12mg/mL) in which the following parameters were measured: mortality of females (%), hatchability of eggs (%), and product efficiency (%). Larvae were assessed by the Larval Packet Test at concentrations ranging from 25.00 to 0.00004mg/mL. Lethal concentrations (LC) required for killing 50 and 99.9% of adult females and larvae were determined using Probit analysis. LC50 and LC99.9 of EO were 0.06 and 24.60mg/mL and 1,208.80 and 2,538mg/mL for larvae and adult females, respectively. Action of the EO in the free-living cycle of R. (B.) microplus larvae was another parameter assessed. To this end, the larvae were deposited in pots containing Brachiaria decumbens and, after migration to the leaf apex, a solution containing LC99.9 (24.60mg/mL) of the EO was sprayed. After 24h, 72.25% of the larvae had died, indicating stability of the EO when subjected to uncontrolled temperature and humidity conditions. The mechanism of action through which the EO killed the larvae and adult females was investigated by the Bioautographic Method, which showed inhibition of 3.15mg/mL of the EO on the acetylcholinesterase (AChE) enzyme. The results found in the present experiment indicate that E. pyriformis essential oil is an alternative in the control of southern cattle tick in the larval (parasitic) and free-living cycle (non-parasitic) stages under field conditions.

Essential oil from leaves of Nemuaron vieillardii (Baill.) Baill., a shrub used in the kanak pharmacopeia, was analyzed by gas chromatography and combined gas chromatography-mass spectrometry. The main compounds identified were safrole (49.7%), linalool (8.0%), δ-cadinene (5.1%), caryophyllene oxide (4%) and α-copaene (2.4%). This chemical composition is consistent with leaf oils of the Atherospermataceae family and demonstrates the proximity of the two genera Nemuaron and Atherosperma as regards to their essential oil compositions. The modified Larval Packet Test (LPT) was used to assess acaricidal effect of N. vieillardii essential oil on larvae of the cattle tick Rhipicephalus (Boophilus) microplus and LC50 was then calculated to 14.67%. High content of safrole in this oil which is suspected of being a human carcinogen, poses the problem of the use of this oil in a perspective of development of alternative tick control strategy and in the traditional medicinal consumption of Nemuaron vieillardii.
