“…An analogous study found that Metarhizium species produced conidia with oval and rod‐like morphologies, as well as pale green pigmentation [15–17]. In contrast, the fungal isolates had conidia that were similar in size and shape to those described by Goldsmith et al [37].…”

“…Los HE son importantes antagonistas de insectos plaga que habitan en el suelo (Uzman et al, 2019), y su presencia ha sido ampliamente estudiada en México en diversos cultivos como cítricos (Galán-Franco et al, 2011) Bravo et al, 2021). En Arkansas, EUA y utilizando como insecto trampa el ácaro Amblyomma americanum (Acarina: Ixodidae), lograron aislar e identificar molecularmente a las especies de M. robertsii y M. guizhouense (Goldsmith et al, 2021); lo que demuestra la capacidad de adaptación de estas dos especies a diferentes condiciones ambientales y hábitats. En este estudio, la mayor abundancia de HE se presentó durante la temporada de lluvias, presentando el 64,7% de las larvas micosadas, seguramente favorecido por la humedad que se presenta en esa época del año, la cual beneficia la germinación de conidios y su propagación en el suelo (Ignoffo, 1992).…”

“…To accomplish this objective, un-engorged A. americanum adults and nymphs of both sexes were obtained from sheep and rabbit hosts housed at the Oklahoma State University (OSU) Tick Rearing Facility, Stillwater, OK. A native isolate of M. robertsii, Savoy P10N1 (ARSEF 14329), was sub-cultured from an infected A. americanum inoculated from a preliminary bioassay. Savoy P10N1, hereafter called P10N1, was isolated from a field-collected tick exposed to soil collected from the Savoy Beef Cattle Research Complex in Savoy, AR (36.128°N, 94.333°W) (Goldsmith et al 2021). Conidia of P10N1 were suspended in a solution of 0.05% Tween 80, 1.5 mg/L penicillin G, and 2.5 mg/L streptomycin.…”
