“…Recent work has demonstrated that a combination of DEET and plant‐derived organic fatty acids may provide an effective and long‐lasting repellent effect against Culicoides . Citronella oil, while known to be an effective mosquito repellent, has been repeatedly shown to have either no repellent effect or potentially an attractant effect on Culicoides .…”

SummaryAfrican horse sickness (AHS) is an arboviral disease of equids transmitted by Culicoides biting midges. The virus is endemic in parts of sub-Saharan Africa and official AHS disease-free status can be obtained from the World Organization for Animal Health on fulfilment of a number of criteria. AHS is associated with case fatality rates of up to 95%, making an outbreak among naïve horses both a welfare and economic disaster. The worldwide distributions of similar vector-borne diseases (particularly bluetongue disease of ruminants) are changing rapidly, probably due to a combination of globalisation and climate change. There is extensive evidence that the requisite conditions for an AHS epizootic currently exist in disease-free countries. In particular, although the stringent regulations enforced upon competition horses make them extremely unlikely to redistribute the virus, there are great concerns over the effects of illegal equid movement. An outbreak of AHS in a disease free region would have catastrophic effects on equine welfare and industry, particularly for international events such as the Olympic Games. While many regions have contingency plans in place to manage an outbreak of AHS, further research is urgently required if the equine industry is to avoid or effectively contain an AHS epizootic in disease-free regions. This review describes the key aspects of AHS as a global issue and discusses the evidence supporting concerns that an epizootic may occur in AHS free countries, the planned government responses, and the roles and responsibilities of equine veterinarians.

“…The use of mesh to protect stabled horses (Barnard, 1997;Meiswinkel et al, 2000) and the efficacy of insect repellents or insecticides applied to mesh surrounding light traps against Culicoides midges have been reported (Braverman and Chizov-Ginzburg, 1998;Page et al, 2009Page et al, , 2014Venter et al, 2011Venter et al, , 2014Del Río et al, 2014a, b). In contrast to the proven efficacy (Lengeler, 2004) and extensive use of pyrethroid-treated mesh against mosquitoes, the use of similar material to protect 3 horses against Culicoides midges has received limited attention (Carpenter et al, 2008a).…”

The efficacy of alphacypermethrin-treated high density polyethylene (HDPE) mesh applied to jet stalls against Culicoides biting midges (Diptera: Ceratopogonidae) was determined by mechanical aspiration of midges from horses and using Onderstepoort 220V downdraught black light traps in four blocks of a 3 x 2 randomised design under South African field conditions. The alphacypermethrintreated HDPE mesh applied to the stall significantly (P = 0.008) reduced the number of Culicoides midges, predominantly Culicoides (Avaritia) imicola Kieffer, mechanically aspirated from horses housed in the stall. The mesh reduced the Culicoides midge attack rate in the treated stall compared to the untreated stall and a sentinel horse by 6 times and 14 times, respectively. The number of Culicoides midges and C. imicola collected in light traps from the untreated and alphacypermethrin HDPE mesh-treated stalls did not differ significantly (P = 0.82). Alphacypermethrin-treated HDPE mesh could be used to reduce exposure of horses in jet stalls to Culicoides midges, specifically C. imicola, and the risk of midge-borne Orbivirus transmission.

“…The essential oil of C. winterianus showed a protective response that was statistically different from the control after the third accumulated dose (8.75 mg/mL). Cymbopogon winterianus has been cited as a plant with strong repellent properties on mosquitoes and other insects since 1901 [24] . A study by Deletre et al [7] .…”

Most of the hematophagous insects act as disease vectors, including Aedes aegypti, responsible for transmitting some of the most critical arboviruses globally, such as Dengue. The use of repellents based on natural products is a promising alternative for personal protection compared to industrial chemical repellents. In this study, the repellent effect of essential oils extracted from Lippia thymoides, Lippia alba, Cymbopogon winterianus, and Eucalyptus globulus leaves was evaluated. Essential oils used showed repellent activity against Ae. aegypti in laboratory bioassays, obtaining protection rates above 70 % from 3.75 mg/mL and higher concentration for all analyzed oils. GC/MS identified 57 constituents, which were used in the ligand‐based pharmacophore model to expose compounds with requirements for repellents that modulate mosquitoes behavior through odorant‐binding protein 1 Ae. aegypti. Ligand‐based pharmacophore model approach results suggested that repellent activity from C. winterianus, L. alba, and L. thymoides essential oils’ metabolites is related to Citronelal (QFIT=26.77), Citronelol (QFIT=11.29), Citronelol acetate (QFIT=52.22) and Geranil acetate (QFIT=10.28) with synergistic or individual activity. E. globulus essential oil's repellent activity is associated with Ledol (0.94 %; QFIT=41.95). Molecular docking was applied to understand the binding mode and affinity of the essential oils’ data set at the protein binding site. According to molecular docking, Citronelol (ChemPLP=60.98) and geranyl acetate (ChemPLP=60.55) were the best‐classified compounds compared to the others and they can be explored to develop new repellents.
