Estrategias de Control

• Hospedador Agente y Ambiente (T°)

• Distintos comportamientos , preferencias , ciclos de vida y susceptibilidad a Hongos

• Adaptacion a la garrapatablanco y al ambiente propiode la garrapata

Condiciones de Campo

High temperature, strong solar ultraviolet (UV) radiation and desiccation, often severely reducing the persistence of fungal conidia in the field; and, thereby, reduce the efficacy of fungal biological control products

Rangel et al., 2004; Braga et al., 2002

Entomopatogenicidad Diferencial

• Thermotolerance and cold activity

• Genotypes An intensive search for promising fungal biological control agents of ticks, particularlyRhipicephalus microplus Éverton K.K. Fernandesa,b Isabele C. Angeloa, Drauzio E.N. Rangel, Veterinary Parasitology 182 (2011) 307– 318
