Galeopsomyia fausta (Hymenoptera: Eulophidae) is a thelytokous parasitic wasp attacking the citrus leafminer,Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae). To improve the performance of that wasp as a natural enemy, the nature of its uniparental reproduction was studied.

Chromosoma, 1976
Two mosaic sibling embryos of the Australian plague locust, Chortoicetes terminifera are reported with haploid and diploid cell lines in widely differing proportions. One small chromosome pair involved in the two cases has alternative morphology and a B-chromosome is present in one.

Chromosoma, 1972
Parthenogenesis is reported in three soft scales with 2n=16. In the unfertilized eggs of all three, oogenesis is normal and diploidy is restored by the fusion of the division products of the haploid female pronucleus. In Lecanium putmani Phillips 12 of 13 uninseminated females collected in the wild produced only males.

AbstractThelytokous reproduction was developed and fixed in arrhenotokous Muscidifurax raptor Girault and Sanders by mating hybrid females, of interhemispheric strains, with naturally occurring males of M. uniraptor Kogan and Legner. A change in ovipositional behavior was shown by these mated hybrid females which subsequently produced thelytokous Fx ...

Haplodiploidy is the sex determination mode of all Hymenoptera. Whereas most species reproduce by arrhenotokous parthenogenesis (males develop from unfertilized eggs and females from fertilized eggs), many reproduce by thelytokous parthenogenesis (unfertilized eggs develop into diploid females).
