“…Our results are well consistent with other studies where it has been found that DM was more effective against ticks and showed 70 % mortality at the dose (25 ppm) when compared with Cym [14]. Further, Batiste Alentron et al [15] have reported that the Cym was more toxic than fenvalerate on the larval and adult stage of Drosophila melanogaster; Age and condition of ticks before are pivotal as to the variability of results [16], these factors were standardized in standard laboratory conditions, and consistent results were obtained.…”

Arthropods are highly effective vectors for a number of life threatening pathogens, parasites, viruses etc., across the world. Hyalomma dromedarii Koch is the prominent tick species infesting camels. Therefore, in this research we studied the insecticidal efficacy of commercially available deltamethrin (DM), Cypermethrin (Cym) and α-Cypermethrin (α-Cym) in the fight against the adult of H. dromedarii through in vitro immersion bioassays. In this study, different concentrations of all selected synthetic insecticides (25, 50, 100, and 150 ppm) were freshly prepared. In toxicity assays, compared to Cym, adult tick mortality was found to be higher in DM followed by α-Cym treated ticks. The mortaltiy rates were increased after 48 h post-treatment of synthetic pyrethroids when compared with 24 h and the LC50 values for 24 h posttreatment with DM, Cym and α-Cym were 66.93, 129.72, and 81.08 ppm respectively, whereas that 48 h post-treatment were 4.23, 37.25, and 3.12 ppm. Our findings suggest that the DM and α-Cym were more effective against adult Hyalomma dromedarii than Cym.

“…The tabulated data concluded that the efficiency of Butox 5% and diazinon was more than that of 10% hexane extract against infested ticks. Despite the fact that the data of our current study indicated that synthetic chemical insecticides were more efficient in controlling ticks than neem extract oil, the application of neem at higher doses on affected animals might offer many advantages for the control of ectoparasites without the risk of toxicity to them (72).…”

Acaricidal Properties of Four Neem Seed Extracts (Azadirachta indica) on the Camel Tick Hyalomma dromedarii (Acari: Ixodidae)

Tick infestation remains one of the major health problems that affect the productivity and comfort of camels. The control of ticks mainly relies on using chemical acaracides. Limited information is available on the potential benefits and activity of various neem extracts on Hyalomma ticks. The present study investigated the acaricidal activity of neem seed extracts at different concentrations against developmental stages of the camel tick Hyalomma dromedarii in comparison to Butox and diazinon. The acaricidal activity of three extracts, namely, hexane extract (HE), methyl chloride extract (MCE), and methanol extract (ME), of neem seeds (Azadirachta indica) were tested at varying concentrations of 5, 10, 15, and 20% on engorged H. dromedarii female ticks at days 1, 3, 5, 7, 12, 16, 20, 28, 37, and 43 after treatment (DPT). Interestingly, results of applying different neem seed extracts to engorged H. dromedarii female ticks showed that the most effective extract was hexane at concentration 20%, causing 100% mortality at 1st day post-application, while methanol extract at 20% and dichloromethane extract at 20% caused the death of all ticks at 28th day posttreatment as compared to Butox® 5.0 and Diazinon-60, which resulted in mortality of all ticks at 3 and 5 DPT, respectively. In addition, no mortality was reported with the application of aqueous extract (AE), which served as the control group. Furthermore, the neem hexane extract exhibited high efficacy against reproductive performance of female ticks, whereas no fertility or oviposition was reported at all of their concentrations. Additionally, no hatchability occurred using all neem extracts, except the aqueous extract, which showing no effect. In the present study, larvae responded more rapidly to the plant extracts, whereas mortality of all larvae was recorded at 24 h after treatment with 5% hexane. Taken together, this study pointed out that the acaricidal effect of hexane extract of neem seeds was more effective and could be economically used for controlling H. dromedarii ticks.

“…The present outbreak of ASF in India is still not known in the context of transmission involving tick vectors/biting flies/infective secretions and tissues or possibility of indirect transmission by fomites. Since Ornithodoros species have already been found to be associated with other diseases and its prevalence has been reported from Gujarat [ 52 , 58 ], Nilgiri Hills and the adjoining areas of Tamil Nadu [ 59 ], there may be a possibility of involvement of Ornithodoros species with the present outbreak of ASF in NE India. The paucity of research on prevalence of Ornithodoros ticks and their probable role in the transmission of various diseases of animal and public health importance in the country might further enhance the possibility of future outbreaks of ASF in other pig rearing states of India.…”

African swine fever (ASF) is one of the most important transboundary diseases of pigs. ASF has been identified in India for the first time in domestic pigs from outbreaks reported in two of the northeastern states, Arunachal Pradesh and Assam in 2020. A total of 11 ASF outbreaks in different regions killed over 3700 pigs and devastated the economy of small-scale livestock owners of both the states. Considering the first outbreak of ASF in India, a generic risk assessment framework was determined to identify potential risk factors that might favor future emergence of the disease. Based on the Indian scenario, we considered population density of host, farming practice, availability of biological vectors and wildlife reservoirs, epidemiological cycles, and international trade to analyze the possibility of future outbreaks of ASF and chances of establishment of endemism. On critical analysis of the identified risk factors associated with ASFV transmission, we observed that the risk factors are well preserved in the Indian geography and might participate in future outbreaks, further disseminating the disease to nearby countries. Since no vaccine is currently available against ASF, the domestic and the wild pigs (wild boars and the endangered pygmy hogs native to India) of this region are under constant threat of infection. For the near future, this region will have to continue to rely on the implementation of preventive measures to avoid the devastating losses that outbreaks can cause. The various adaptive control strategies to minimize the risks associated with the transmission of ASF, keeping our views to Indian settings, have been described. The risk-analysis framework presented in the study will give a further understanding of the dynamics of disease transmission and will help to design control strategies and corresponding measures to minimize the catastrophic consequences of ASF disease.
