“…In addition, many species of dung‐breeding insects have multiple generations/year. Depending on the climate, the number of generations/year for the pestiferous horn fly is commonly 6 to 9 (Showler et al, 2014), but may be as many as 30 (Melo et al, 2020). Repeated exposure of a pest species to insecticidal residues in dung across multiple generations following a single application of LongRange to cattle may be desirable, but further enhances the risk to populations of nonpest and beneficial species.…”

Cattle treated with LongRange®, an injectable formulation of the parasiticide eprinomectin, fecally excrete insecticidal residues for an extended period post application. We examined the nontarget effect of these residues by comparing insect communities developing in dung of untreated cattle (week 0) with those developing in dung of cattle treated 1, 2, 4, 8, 12, 16, 20, and 24 or 25 weeks previously. Chemical analyses of dung showed that eprinomectin concentrations peaked at 1 week post application and were still detectable at 25 weeks. Results from two separate experiments showed that dung of untreated cattle supported more total insects (beetles, flies, parasitoid wasps) and insect species than did dung of cattle treated for ≤12 weeks (Experiment 1) and ≤25 weeks (Experiment 2) previously. For the two experiments, an effect of residue on individual taxa was either not detected (nine cases) or was determined to suppress insect development in dung of cattle treated for 8–12 weeks (two cases), 12–16 weeks (three cases), 16–20 weeks (two cases), or 24 or 25 weeks (six cases) previously. Flies and their parasitoid wasps were particularly sensitive to residues with suppression often at or near 100%. These results show that cattle treated with LongRange in spring will fecally excrete residues for the entire grazing season with an associated simplification of the dung insect community. The effect of this simplification on the long‐term health on dung‐breeding populations of insects on pastures and dung degradation was not examined in the present study, but merits future research.

La mosca de los cuernos Haematobia irritans es un ectoparásito hematófago cosmopolita de gran importancia en la ganadería. En México, H. irritans se distribuye por todo el país y se encuentra durante todo el año. La fluctuación de la población de H. irritans está relacionada con las condiciones climáticas. A pesar de su amplia distribución, los efectos sobre la salud animal y su impacto negativo en la producción de carne y leche, existen pocos datos sobre su infestación y su epidemiología es limitada. Este trabajo es una revisión sobre la situación actual de H. irritans en bovinos en México, su impacto económico, métodos de control, perspectivas y oportunidades de investigación.
