The entomopathogenic fungus Beauveria bassiana is one of the most promising bio control agent against Plutella xylostella. Laboratory bioassays were conducted to study the virulence of ten isolates of B. bassiana against 3rd instar larvae of the P. xylostella. The B. bassiana isolates used in the study were obtained from cadaver of Indarbela quadrinotata. Initially, a survey was carried out in ten guava orchards located at SHUATS, Mahewa, Jhalwa, Preetam Nagar, Khusrubagh, Meza, George Town, Johnstonganj andAllahpur of Allahabad district, and Kaushambi in September to October during 2013-2015 and total 20 isolates were obtained. Maximum 4 isolates were collected from Jhalwa. Isolate Bb 3 from Jhalwa (63.33%) recorded maximum mean per cent mortality. All this isolate showed promise for use as bio control agents against P. xylostella.
