“…In agricultural crops, entomopathogenic fungi applied to foliage may be affected not only by sunlight exposure but also by rain, temperature variation, humidity, leaf surface chemistry, and phylloplane microbiota (see Jaronski 2010). On parasiteinfested livestock, in addition to the environmental factors noted above, the efficacy of topically applied fungal products may challenge the host-skin environment, with special consideration to the skin temperature, pH, secretions, sweat (with many components such as a wide range of ions), and skin microflora (Polar et al 2008;Fernandes et al 2012). Therefore, screening for promising fungal strains and formulating them for their tolerance to UV is just one of the basic important factors to be considered before evaluating the efficacy of the formulation in complex field experiments for pest control.…”

Ultraviolet radiation from sunlight is probably the most detrimental environmental factor affecting the viability of entomopathogenic fungi applied to solar-exposed sites (e.g., leaves) for pest control. Most entomopathogenic fungi are sensitive to UV radiation, but there is great inter- and intraspecies variability in susceptibility to UV. This variability may reflect natural adaptations of isolates to their different environmental conditions. Selecting strains with outstanding natural tolerance to UV is considered as an important step to identify promising biological control agents. However, reports on tolerance among the isolates used to date must be analyzed carefully due to considerable variations in the methods used to garner the data. The current review presents tables listing many studies in which different methods were applied to check natural and enhanced tolerance to UV stress of numerous entomopathogenic fungi, including several well-known isolates of these fungi. The assessment of UV tolerance is usually conducted with conidia using dose-response methods, wherein the UV dose is calculated simply by multiplying the total irradiance by the period (time) of exposure. Although irradiation from lamps seldom presents an environmentally realistic spectral distribution, laboratory tests circumvent the uncontrollable circumstances associated with field assays. Most attempts to increase field persistence of microbial agents have included formulating conidia with UV protectants; however, in many cases, field efficacy of formulated fungi is still not fully adequate for dependable pest control.

“…The entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae are the most promising bio controllers against both agricultural [1,2] and medical/veterinary pests, including some important arthropods ticks and mites, which parasitize humans and/or animals, i.e., Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Psoroptes spp., Dermanyssus gallinae [3][4][5][6][7].…”

“…Los hongos entomopatógenos han demostrado tener gran potencial para el control biológico de Rhicephalus (Boophilus) microplus (Ojeda-Chi et al, 2011;Fernandes et al, 2012). En condiciones de campo, la patogenicidad puede estar afectada por factores macroclimáticos tales como temperatura, humedad y radiación solar, así como factores microclimáticos, como secreciones químicas de la piel del animal, microflora y temperatura de la piel, los cuales Beauveria bassiana 1.3X10 12 conidias/ml, con 67.42 % en condiciones de campo, con aplicaciones repetidas cada 15 días, en horas de baja radiación solar (07:00-08:00); este porcentaje de mortalidad disminuyó con el paso de los días debido a que había una interacción entre el ambiente, las garrapatas del animal y los hongos, que condiciona la efectividad de estos últimos.…”

ResumenEn México el problema principal de la ganadería bovina, en lo particular en el trópico, es controlar las garrapatas Rhicephalus (Boophilus) microplus, ya que el uso inadecuado de los tratamientos químicos ha creado resistencia en esos parásitos. El control biológico en garrapatas es un concepto nuevo y ha sido una medida efectiva, que ha permitido mantener estas dentro de parámetros económicos y zoosanitarios aceptables. Una de las posibilidades reales en este campo para controlar garrapatas Rhicephalus (Boophilus) microplus de importancia pecuaria es el uso de hongos entomopatógenos como el Metharrizium anisopliae y Beauveria bassiana. La finalidad del presente estudio fue observar la capacidad patógena de dos cepas de Metarhizium anisopliae a dosis de 1X10 8 conidias/ml y 1.3X10 12 conidias/ml, y de una cepa de Beauveria bassiana a una dosis de 1.3X10 12 conidias/ml en unidades de producción en bovinos de doble propósito, en los municipios de Emiliano Zapata
