“…The larvae of these flies are carnivorous and feed on the body tissues and fluids of livestock (condition known as myiasis) (Zumpt, 1965) to such an extent that animal production and health is detrimentally affected (Farkas et al, 1997;Snoep et al, 2002;Sotiraki and Hall, 2012). The condition has been managed by the use of chemical pesticides either in the environment or on the animals themselves (Tellam and Bowles 1997).…”

Ethnopharmacological relevance: The leaves of Clausena anisata are used traditionally to expel maggots from wounds of animals in Zimbabwe. We have previously proved in the laboratory that the plant certainly affects the behaviour and growth of blowfly larvae. The objective of this study was to isolate and identify the active compounds responsible for this activity. Materials and Methods:The acetone extract of C. anisata leaf powder was separated by solvent-solvent partition into five fractions. The n-hexane fraction was the most active in the larvicidal assay and therefore subjected to open column chromatography on silica gel. Results:The isolated compound was identified by nuclear magnetic resonance (NMR) and mass spectroscopy (MS) as the pyranocoumarin, seselin, chemically known as 2,2-dimethylpyranocoumarin . It inhibited feed intake in the first and second instars of blowfly larvae at the minimum concentration tested of 1ppm resulting in significant lower mass pupae (13.5 ± 0.5 mg and 22.4 ± 0.4 mg for the first and second instar larvae respectively) compared to the solvent control group (26.19 ± 0.8 mg) (p < 0.05).Conclusions: This is the first report of the isolation of seselin from the leaves of C. anisata and the first report of the compound having an effect against blow fly larvae.

“…A epidemiologia de miíases em ovinos criados na Holanda indicou que a região mais acometida foi a cauda dos animais e foram relacionadas principalmente a elevadas temperaturas e umidade relativa do ar (Snoep et al 2002). Esses relatos podem sugerir que diferenças de manejo e a região geográ-ϐica de criação dos animais possam inϐluenciar os locais de ocorrências das lesões, ou possivelmente ás espécies de moscas prevalentes em cada região geográϐica.…”

Pesq. Vet. Bras. 32(6):490-494, junho 2012 490 RESUMO.-A ocorrência de miíases cutâneas foi veriϐicada em 10 diferentes criatórios de ovinos no norte de Minas Gerais, Brasil, durante o período de um ano, onde foram analisados os fatores relacionados a essas parasitoses. Os rebanhos possuíam predominantemente animais mestiços Santa Inês, criados em sistemas semiextensivo. Foram registrados 50 casos e a maior incidência foi observada nos meses de março (22%) e abril (18%), períodos de maiores temperaturas e umidade relativa do ar. As patas foram as regiões mais frequentemente acometidas (34% dos casos). As lesões por pododermatites (38% dos casos), onfaloϐle-bites (10%), linfadenite (6%) e dermatobiose (6%) foram os fatores mais frequentemente relacionados às miíases. As Cutaneous myiasis was investigated in 10 sheep herds during one year in northern Minas Gerais, Brazil, and factors related to its occurrence were analyzed. The sheep were predominantly hybrid Saint Inês, bred in semi-extensive systems. A total of 50 cases were registered and the highest incidence occurred during March (22%) and April (18%), months with high temperatures and high relative humidity of the air. There was no inϐluence of sex and age for the occurrence of myiasis. The lesions were mostly found on the legs (34% of the cases). Pododermatitis (38% of the cases), omphalophlebitis (10%), lymphadenitis (6%) and dermatobiosis (6%) were the predisposing factors more frequently associated with myiasis. The myiasis was not correctly treated by the owners, but after implantation of a correct therapy, 92% of the lesions presented cure within 7 to 30 days. The results show the importance of preventive strategies based on the predisposing factors identiϐied in this study. The constant inspection, identifying wounds and precociously treating the lesions, should be routine especially at the end of rainy season and when predisposing factors are present.INDEX TERMS: Cochliomyia hominivorax, miyasis, sheep, predisposing factors, semiarid.

“…However, the context is quite different: principal insect attacks concern the Calliphoridae and Sarcophagidae (Dipterous inducing myiasis) that are particularly dangerous because larvae grow in sheep tissues, digging in. Attacks, mainly observed in the area around the tail, seem linked to dung spread by the tail (Snoep et al, 2002). In such a context, docking is widely considered to prevent faecal soiling and fly strike.…”

“…In such a context, docking is widely considered to prevent faecal soiling and fly strike. However, scientific studies are not unanimous: whereas French et al (1994a) showed that intact lambs underwent more fly attacks than docked lambs, in relation with improved rear cleanliness, two other studies (French et al, 1994b;Snoep et al, 2002) showed that docking was associated neither to a lower myiasis prevalence nor to less insect attacks. In addition, docking lambs too short can increase the incidence of fly strike (Watts and Marchant, 1977;Watts and Luff, 1978; see also Watts and Perry, 1975;.…”

Routinely performed painful procedures are of increasing interest and, in 2001 (Royal Order, May 17), Belgium prohibited docking in several vertebrates including horses. In 2004, opponents to this decision submitted a Bill (Doc51 0969/001) to Parliament, intending to obtain derogation for Belgian draught horses, which were traditionally docked. The Animal Welfare Council of Belgium, an official body advising the Minister of Public Health, was asked to evaluate this complex question, including biological, ethical and socio-economic aspects, on the basis of the available peer-reviewed studies. In this context, this study reviews legal aspects (overview of the European legislation), zootechnic aspects (uses of the Belgian draught horse) and biological aspects (pain potentially related to docking; horses’ welfare linked to insect harassment and hygiene, communication and reproduction) of tail docking in draught horses. We conclude that (1) there is no benefit for horses in tail docking, including Belgian draught horses, (2) potential advantages of docking are essentially in favour of humans and these advantages could be scrupulously re-evaluated, taking into account practices of other countries. Therefore, there is no need to dock any horse other than for veterinary reasons.
