An extensive survey was conducted in the Kumaun and Garhwal divisions of Uttarakhand. Both insect cadavers and soil samples were collected for the purpose of isolation of local strains of entomopathogenic fungi. Nomuraea rileyi was the most predominant entomopathogen isolated from the mycosed larvae followed by Beauveria bassiana. Trichoplusia orichalcea showed more cases of mycosis. Some B bassiana affected coleopteran (beetle) in the soybean field were also collected. Maximum number of mycosed cadavers were collected in the month of September, followed by November and October respectively and none in December. The maximum number of mean diseased insects per meter square was reported at Fatehpur area of Udham Singh Nagar District in the month of September. Isolates were extracted from soil samples also. 52 soil samples were collected for this purpose. Metarhizium anisopliae followed by B bassiana dominated the soil samples. The collected soil samples upon testing yielded a total of six entomopathogenic fungi among which M anisopliae was the predominant one.
