“…These products have been developed for use against a range of veterinary and medical pests including dust mites, ticks, ectoparasitic mites (including D. gallinae ), scabies mites ( Sarcoptes scabiei ) and head lice ( Pediculus humanus capitis ). Such products may be highly efficacious, with MiteStop® reported to be more effective against D. gallinae than the synthetic organophosphate phoxim [19]. This same group has recently shown that a similar product (Licener®) can be highly efficacious against the human head louse [20], as are comparable products based on work elsewhere [21].…”

Present and future potential of plant-derived products to control arthropods of veterinary and medical significance

et al. 2014

The use of synthetic pesticides and repellents to target pests of veterinary and medical significance is becoming increasingly problematic. One alternative approach employs the bioactive attributes of plant-derived products (PDPs). These are particularly attractive on the grounds of low mammalian toxicity, short environmental persistence and complex chemistries that should limit development of pest resistance against them.Several pesticides and repellents based on PDPs are already available, and in some cases widely utilised, in modern pest management. Many more have a long history of traditional use in poorer areas of the globe where access to synthetic pesticides is often limited. Preliminary studies support that PDPs could be more widely used to target numerous medical and veterinary pests, with modes of action often specific to invertebrates.Though their current and future potential appears significant, development and deployment of PDPs to target veterinary and medical pests is not without issue. Variable efficacy is widely recognised as a restraint to PDPs for pest control. Identifying and developing natural bioactive PDP components in place of chemically less-stable raw or 'whole’ products seems to be the most popular solution to this problem. A limited residual activity, often due to photosensitivity or high volatility, is a further drawback in some cases (though potentially advantageous in others). Nevertheless, encapsulation technologies and other slow-release mechanisms offer strong potential to improve residual activity where needed.The current review provides a summary of existing use and future potential of PDPs against ectoparasites of veterinary and medical significance. Four main types of PDP are considered (pyrethrum, neem, essential oils and plant extracts) for their pesticidal, growth regulating and repellent or deterrent properties. An overview of existing use and research for each is provided, with direction to more extensive reviews given in many sections. Sections to highlight potential issues, modes of action and emerging and future potential are also included.

“…Therefore, the use of biological materials instead of chemicals in the control of parasites was documented in the last few years. It is proven that the naturally occurring products in plant extracts have potency against different pathogens and are mostly safe in use (Nassar et al 1997;Abdel-Ghaffar and Semmler 2007;Mehlhorn 2008;Cenci et al 2007;Abdel-Ghaffar et al 2009;2010a, b). The present study aims to examine the incidence of the most dominant cestodes infecting sheep and their prevalences throughout the whole year.…”

Out of 2,343 examined sheep throughout the whole year, 271 were found to be infected with tapeworms (11.5%). The highest infection rate (22.1%) was recorded in autumn, while the lowest (6%) occurred in summer. Six species of cestodes were identified according to their prevalence: Moniezia expansa (74%), Moniezia denticulata (8.5%), Moniezia benedeni (4.8%), Moniezia trigonophora (2.7%), and Thysaniezia giardi (2.7%), T. giardi was recorded in Egypt for the first time. M. expansa was found throughout the year with two peaks in January (92.3%) and June (88.5%). SEM examination revealed that M. expansa scolex has four triangular suckers guarded by an X-shaped fibrous band that makes them open permanently. Also, there is a Y-shaped apical part at the scolex center which may be an embryonically non-developed rostellum. The whole worm body surface is covered with unidirectional microtriches. TEM showed that the tegument is underlaid by a thick fibrous interstitial layer below which an outer circular and an inner longitudinal muscular layer are arranged. Beneath these structures the subtegumental cells are found which have spherical electron-dense inclusions and various other cell organelles. Moreover, M. expansa has interproglottidal glands which contain secretory vesicles and secretions. For biological control of this parasite, different concentrations of crude plant extract of Artemisia cina were used in vitro and in vivo. In vitro, the results indicated that the plant extract is efficacious at all concentrations tested. Electron microscopic examination showed that many structures of the treated worms were affected. The most affected sites were the scolex and the microtriches of the outer tegumental surface. In vivo, treatment of heavily infected animals showed an antihelminthic effect, since the complete absence of eggs was recorded 9 days after treatment when fecal investigations were done.

“…In addition, in the past, resistances have been developed against most of the older insecticides, e.g., phoxim has today only a reduced efficacy against the red bird mite, D. gallinae ). On the other hand, the biological compound MiteStop® based on a neem seed extract has a very high and broad efficacy against a wide spectrum of mites, ticks, and insects that molest animals and humans (Heukelbach et al 2006;Abdel-Ghaffar et al 2008a, b;Abdel-Ghaffar and Semmler 2007;Schmahl et al 2010;Semmler et al 2009;Abdel-Ghaffar et al 2009;Locher et al 2010a;b). Just recently, it was shown that this product is not only able to kill general pests of animals and humans but also acts very specifically against the biting lice of horses ) and against beetles from the families Tenebrionidae and Dermestidae, the larvae of which may enter the plumage of poultry and feed on tiny feathers or on skin debris .…”

Effects of a neem seed extract (MiteStop®) on mallophages (featherlings) of chicken: in vivo and in vitro studies

Mallophages of birds (featherlings) are mostly very tiny and can even as adults better be recognized by their movements than by their elongate body shape when using just the naked eye. Since some species (e.g., the "shaft louse" Menopon gallinae, the elongate feather louse Lipeurus caponis, or Columbicola sp.) may pierce the pulp of feathers or the skin by their biting or scratching mandibles and thus lick the excreted blood, they may be extremely dangerous especially to young birds, even if they only feed by nibbling along the feather surface and/or eat epidermal debris. The present paper reports on the successful treatment of different races of fowls being severely infested with both above cited species. This in vivo treatment was done either by a short dipping of the whole fowl into the 1:33 dilution (with tap water) of a neem seed extract (MiteStop®) or by spraying them with the freshly diluted product. It was seen that the dead mallophages dropped down from the feathers as soon as they were dry again. As a precaution, a second treatment was done by some owners 1 week after the first one in order to eliminate all stages, which eventually might have hatched from untouched nits during the time interval between the two treatments. When controlling the treated fowls 4 weeks after the treatment, in no case (treated once or twice), living motile stages were diagnosed indicating the high efficacy of this nontoxic neem seed extract. When treating in vitro cutoff feathers contaminated with L. caponis, it was seen under the stereomicroscope, that the mallophages tried to run away from the 1:33 water-diluted active compound indicating that there is also a repellent effect. Treated L. caponis stopped leg movements within 3 min and died on their feathers within 1-20 min. Then, the last slight trembling movements of their legs and convulsions of their intestine stopped finally.
