Unformatted text preview: e killing is the result of successful copulation, whereby Wolba chi a -infected haploid eggs are
killed by the infection itself, leaving only diploid eggs in the brood, and thus resulting in an allfemale, but much smaller than normal, filial generation; this presumably serves the purpose of
reserving all the available resources for the diploid female offspring, thus increasing their chance
of surviving and passing on the infection, by eliminating those known not to pass on the
infection. Finally, in feminization, the Wolba chi a will override the normal masculine
development of the haploid males, and instead force them to become haploid females and
pseudo-females, which are often infertile. (Werren, 2003)
From the patterns of offspring formation thus described, this experiment was conceived
with two main goals in mind: the fir
Wolba chi a infection also result in phenotypic modification of mating patterns of their N asoni a
host when mating with other, nonsecond goal was to distinguish
between infected and uninfected strains of N asoni a based on crosses and sex-ratio analysis alone.
