dc.description.abstractThysanoptera are haplo-diploid insects that reproduce either via arrhenotoky or thelytoky. Beside genetically based thelytoky, this reproduction mode can also be endosymbiont induced. The recovery of these females from their infection again leads to the development of males. Functionality of these males ranges widely, and this might be associated with sperm structure. We analyzed the sperm ultrastructure in three different species belonging to both suborders with different reproduction systems via electron microscopy. Beside the different reproduction modes, and adaptations to their life style, the arrhenotokous species Suocerathrips linguis (Thysanoptera: Tubulifera) and Echinothrips americanus (Thysanoptera: Terebrantia) possess typical thysanopteran-like sperm structure. But endosymbiont-cured males from the thelytokous species Hercinothrips femoralis (Thysanoptera: Terebrantia) possess several malformed spermatozoa and a large amount of secretions in their testes. Spermiophagy seems to be typical. It indicates a highly conserved mechanism of the male developmental pathways, despite the observed decay. However, this decay would explain why in some species no stable arrhenotokous line can be re-established.eng
