“…Reduction of the risk of infection focuses often on the recurrent treatment of equids, with the objective to decrease the presence of eggs which might result in elevated counts of third-stage larvae in the ground [ 28 ]. However, certain anthelmintics might be ecotoxic on organisms in charge of enriching the soil, such as the dung beetles, and necessary for decomposing manure [ 29 , 30 ]. Some measures have been pointed to limit the contamination of grasslands, as the regular manual collection of feces (every 2-4 days) or pasture rotation [ 27 , 31 ].…”

The integrated control of strongyles was assayed for a period of three years in wild equids (zebras, European donkeys, and African wild asses) captive in a zoo and infected by strongyles. During three years control of parasites consisted of deworming with ivermectin + praziquantel; equids also received every two days commercial nutritional pellets containing a blend of 104 - 105 spores of the fungi Mucor circinelloides + Duddingtonia flagrans per kg meal. Coprological analyses were done monthly to establish the counts of eggs of strongyles per gram of feces (EPG). The reductions in the fecal egg counts (FECR) and in the positive horses (PHR) were calculated fifteen days after deworming; the egg reappearance period (ERP) and the time elapsed from the previous deworming (TPD) were also recorded. Four anthelmintic treatments were administered during the assay, three times throughout the first 2 yrs, and another treatment during the last one. FECR values of 96-100% and 75-100% for the PHR were recorded. The ERP oscillated between eight and twenty-eight weeks, and the TPD ranged from four to eighteen months, increasing to the end of the trial. No side effects were observed in any of the equids. It is concluded that integrated control of strongyles among equids captive in a zoo can be developed by anthelmintic deworming together with the administration of pellets manufactured with spores of parasiticide fungi every two days.

“…On the other hand, females could invest more than males in immunity to extend their lifetime and thus maximize their rate of egg production (Rolff 2002). Previous studies have indeed shown that ivermectin affects male and female dung beetles differently (Desneux et al 2007;González-Tokman et al 2017b). Although the negative effects of ivermectin and herbicides on dung beetles have been documented, this knowledge has come mainly from controlled laboratory conditions.…”

The use of veterinary medical products and herbicides is a common practice in intensified livestock systems. These compounds affect nontarget organisms that perform important ecosystem functions, such as dung beetles. The assessment of body condition allows us to determine how individuals respond to changes in the environment. However, assessments of how contamination associated with cattle farming affects coprophagous insects such as dung beetles have not been conducted in natural systems. In the present study, we evaluated the effect of ivermectin (an antiparasitic drug) and herbicides on the body condition of 3 species of dung beetles collected in the field: Copris incertus, Euoniticellus intermedius, and Digitonthophagus gazella. We recorded 3 condition indicators (body size, lipid mass, and muscle mass) of beetles collected from 19 livestock ranches in northeastern Mexico. In general, the use of ivermectin had adverse effects on C. incertus and E. intermedius whereas the effects were positive for D. gazella. Conversely, the use of herbicides had adverse effects on D. gazella and positive effects on C. incertus. The different effects of ivermectin and herbicides found in males and females show that sex can be important in determining individual responses to environmental contamination. Importantly, we provide the first evidence under natural conditions that native and exotic species of dung beetles are highly sensitive to different types of livestock management, with veterinary medications and herbicides having the ability to alter body condition. Changes in dung beetle condition can reduce the ecosystem services that dung beetles provide in livestock systems. Environ Toxicol Chem 2019;38:2392–2404. © 2019 SETAC

Se utilizó información proveniente de literatura para compilar el listado de la fauna de Onthophagus de México. Se encontraron un total de 120 especies, de las cuales 85 son endémicas de México. Se incluyen los patrones de distribución originalmente propuestos porHalffter (1964) y comentarios adicionales para la mayoría de las especies. Se encontraron registros de especies para todos los estados de la República Mexicana, con excepción de Baja California. México es el centro de diversificación de Onthophagus de América, con aproximadamente el 62% de las especies descritas para el continente. Oaxaca es el estado con mayor riqueza de especies y mayor número de endemismos. Se discuten los factores que promovieron la diversificación de Onthophagus en México. Onthophagus mesoamericanusZunino y Halffter, 1988 es resucitado de la sinonimia previa.
