1973), Humber (1992), and Carruthers
et al.
(1993) identify
Paecilomyces farinosus
as an important
naturally occurring pathogen of
B. tabaci
in India and
the U.S. However, the identity of the Indian isolates is
questionable in light of the recent discoveries in India
and throughout Asia of extensive epizootics of
Paecilo-
myces fumosoroseus
(Lacey
et al.,
1993). Furthermore,
the U.S. isolates from Texas and California (Humber,
1992) have been reidentified (by S.P.W.) as
P. fumosoro-
seus
based on the size and color of the conidia from
in
vitro
cultures (measuring 1–2
3
3–5 μm and colored
varying shades of pink to mauve, turning gray with
age)
