Abstract
Asexual lineages in the parasitoid wasp Lysiphlebus fabarum (Hymenoptera: Braconidae: Aphidiinae) have previously been shown to have occasionally undergone sexual reproduction and recombination with males from related sexual populations. In the present study, the cytogenetic system of asexual females in this species is shown by 4',6-diamidino-2-phenylindole dihydrochloride (DAPI) staining to be central fusion automixis. This system has the potential to allow occasional sex and recombination without leading to an elevation of ploidy and with the maintenance of at least some heterozygosity. No evidence of the bacterial symbiont Wolbachia was found, and the observed system was compared with that in parasitoid wasps where asexuality is the result of Wolbachia infection.
