An experiment was conducted to introduce
the entomopathogen Beauveria bassiana (Balsamo)
Vuillemin (Ascomycota: Hypocreales) as an endophyte
in jute (Corchorus olitorius), a bast fibre crop through
seed treatment. Colonization of root, leaf, stem, capsule,
and seed were assessed through plating on selective
medium and PCR based detection using B. bassiana
specific SCAR markers. Endophytic colonization was
detected in all the plants grown from treated seeds, but
all the plant parts were not colonized. Colonization was
detected in leaves, stems, and green capsules but not in
roots and seeds. The endophytic colonization was
influenced by both plant part and sampling period.
Colonization was greater in leaves (55.87%) compared
to stems (12.53%) and capsules (42.44%). The percent
colonization was higher in case of 60 days old plants
(43.34%) than in 30 days (23.89%) and 120 days
(35.39%) old plants. As B. bassiana has already been
reported to be pathogenic on jute pests, namely
semilooper (Anomis sabulifera) and bihar hairy caterpillar (Spilosoma obliqua), its season long endophytic
colonization within jute plant suggests a novel approach
of biological control of these pests through seed
treatment with the entomopathogen.ot Available
