The effect of temperature on the growth of acaropathogenic fungi from Hirsutella genus

The aim of the study was to determine effect temperature on growth four species acaropathogenic fungi genus Hirsutella (isolated from mites) grown in vitro Sabouraud (SDA) and Czapek-Dox media. effects seven ranges (5–35°C) were tested under laboratory conditions. Observations colony carried out every 5 days until day 25 by measuring diameter colonies mm. rate test isolates calculated mm per day. conducted studies showed that thermal optimum most between 20°C 25°C, with individual values varying depending type medium which inoculum developed. fungus highest range thompsonii var. synnematosa. It only strain developed both types culture medium, also at 35°C. fastest 25°C. cultures reached larger sizes SDA rather than medium.
