Red mite, Dermanyssus gallinae is one of the serious pests, damaging to the egg production in chickens. Moreover, the overuse of chemical insecticides caused pest resistance and environmental residual toxicity. Therefore, this work provides a screening method to select entomopathogenic fungi as a candidate of environmentally safe control agent, having high miticidal activity against D. Gallinae. The virulence test was conducted using a spraying method. Of the several species, Beauveria species showed high virulence and mycosis were observed. Some isolates were produced on eight cereal grains in Petri dish conditions. Millet, perilla seed and barley showed the high conidia production. Conidia of the isolates produced on millet and rice showed high thermal stability, when exposed to 45℃. Based on these results, this work suggests that entomopathogenic fungi could be used to control the D. Gallinae.
