COMPARISION OF TWO PROPAGULES TYPES of Beauveria bassian against Trialeurodes vaporariorum
Year
: 2004
Abstract: Beauveria bassiana invades their host initially through yeast
bodies, a obligatory parasitic cycle among most entomopathogenic fungi.
virulence of B.bassiana (ATCC 74040) which cultured on SDAY in Yeastlike
cycle toward third nymphal stage of Trialeurodes vaporariorum were
investigated. The conidia of fungus in this phase developed by budding
from germinating conidia after 24h incubation. Average size of cells were
5-10 μm. Colony of fungus were initially circular some later were cover
with mycelia. On the basis of isolate type,timing and growth rate of yeast
inoculum productin varied. Conidia and yeast-like had similar virulence
against Trialeurodes vaporariorum , and average mortality were 65.4 %
with 106 cells/ml. and 78.5 % with 10 7 cells/ml.,respectively. The results
of bioassay indicated that the Yeast-like bodies are effective inoculum for
B. bassiana against insects rather than conidia against some pests. Production
of well-defined yeast phase culture may be essential work for using
bodies, a obligatory parasitic cycle among most entomopathogenic fungi.
