Abstract: The effect of UVC ray s on bioma ss development of Beauve ria bas siana (Ba lsa mo ) Vuillemin combinationwith c hemi cals, vegetable oils a nd oth er s ub s trate s as a dju va nt s were evaluated by expos ing the combinationfor 10 to 50 minute s and 2, 3 and 5 hour s under l abo r atory conditions. It was establish ed that the bioma ssprodu ced b y B. bassiana with or without adjuvants in culture medium after exposure to UVC rays decrea sedwi th increas e in the exposure periods. After 5 hr s UVC rays exposure, the treatment with adjuvant sunfloweroil 1.0 per cent maintain ed its s up eriority over rest of the treatment s a nd d eve loping highe st (6.13 g) biomas s /40 ml medium of B. bassiana fungal mat. It was at par with sunflower oil 0.5 % (6 .07 g). The next effectivetreatments fo r the UVC protectability reflecting in fungal biomass production we re groundnut oil 1.0 %(5.70 g) and 0.5 % (5.63 g). Treatment wi th Tween 80 0.5 % (2 .63 g), mola sses 2.0 % (3.13 g) a nd Tween 80 1.0% (zero g) consistently proved to be inefficient for UVC ray s protectability for B. ba ssia na . As adjuvantsvegatableoils, g hee and indigo 0 .5 % and 1 % gave considerable protection to B. bas s iana from the UVC ra ysproducin g the bioma ss 4.47 to 6.13 g against 6.20 g and 2 .9 2 g biomass development in the une x po sed andex po se d control, resp ectively.
