interpretation of this list is difficult because
it does not constitute an independent sam-
ple of all parasitoid species. One might
expect that the frequency of unisexual
reproduction would be high particularly
for solitary species and species with
extremely small individuals, because for
them the encounter between the sexes
might be the most difficult. Indeed several
trichogrammatid and mymarid genera
appear to be well represented. However,
being small is not a prerequisite for unisex-
ual reproduction, because some of the
largest parasitic wasps species also have
unisexual biotypes, e.g. Pelecinus polyturator
(Johnson and Musetti, 1998).
