| dc.description | The effectiveness of two acaricides was evaluated for control of populations of the southern cattle tick, Boophilus microplus on dairy cattle in St. Croix, U.S. Virgin Islands. Two different concentrations of a microencapsulated (ME) formulation of permethrin (0.05% and 0.10% ai) and one concentration of coumaphos emulsifiable concentrate (EC) (0.117% ai) were sprayed on Holstein heifers that had a natural infestation of ticks. The length of residual activity of EC coumaphos and ME permethrin at 0.05% (ai) was at least four days, and for ME permethrin at 0.10% ai at least seven days.There was no apparent increase in the residual activity period of ME permethrin in comparison to that in field trials of other formulations of permethrin against B. microplus. Percentage control for the three treatment groups from days 4 through 21 was ME permethrin (0.05% ai) 96%; ME permethrin (0.10% ai), 97%; coumaphos, 98.3%. There were no significant differences among the treatment groups (F = 2.21, df = 2,17, P> 0.10). This research confirms the usefulness of permethrin as an alternative to coumaphos for control of B. microplus populations on cattle. | en-US |
| dc.description | Se evaluaron dos acaricidas por su efectividad para controlar las poblaciones de la garrapata sureña Boophilus microplus en ganado lechero en Santa Cruz, Islas Virgenes Americanas. Se asperjaron dos concentraciones diferentes de una formulación microencapsulada (ME) de permetrína (0.05 y 0.10% ia) y una concentración de coumaphos concentrado emulsificable (0,117% ia) sobre novillas Holstein que presentaban una infestación natural de garrapatas. La actividad residual del coumaphos y la permetrina ME (0.05% ia) fue por lo menos de cuatro días y la de permetrina ME (0.10% ia) fue de por lo menos siete días. El largo del periodo residual de la permetrina ME sobre el Boophilus microplus no aumentó en comparación con experimentos de campo con otras formulaciones de permetrinas. El porcentaje de control para los tres tratamientos desde los días 4 al 21 fue: permetrina ME (0.05% ia), 96%; permetrina ME (0,10% ia), 97%; coumaphos, 98.3%. Las diferencias entre las medias de los diferentes tratamientos no fueron significativas (F= 2.21; g.l. = 2,17, P> 0.10). Esta investigación confirma que la permetrina es una alternativa para el control de B. microplus en poblaciones de ganado. | es-ES |
