I solved my question by removing all Index-related files such as
.idx .ilg or .ind
fom the
/tmp/lyx_tmpdir.T15697/lyx_tmpbuf
and saved the document under a new name.
I also put a macro in the preamble of the document
%%macro for index nom
\newcommand{\IndexDef}[1]{\textit{#1}}
and in the document itself
Kalanchoe|IndexDef
where Kalanchoe is a plant name which should appear in the name index as
italics.
However, the page number appears italic, not the plant name.
How should I change the command in the preamble to achieve that?
\newcommand{\IndexDef}[1]{\textit{#1}}
---->??
