Lysiphlebus orientalis (Hymenoptera, Braconidae), a new invasive aphid parasitoid in Europe - evidence from molecular markers [PDF]

open access: yes, 2017
We report the occurrence of Lysiphlebus orientalis in Serbia, an aphid parasitoid from the Far East that is new to Europe and has the potential to become invasive.

The Evolutionary Genetics of Thelytokous Parthenogenesis in Eusocial Hymenoptera

open access: yes, 2014
The phenomenon of thelytoky, the asexual production of diploid female offspring, is being increasingly uncovered among the eusocial Hymenoptera. Thelytoky is associated with a number of fascinating and novel reproductive systems. In this thesis I investigate the evolutionary and genetic consequences of thelytokous parthenogenesis, with particular focus

Studies on the thelytokous parthenogenesis in the scorpion, Liocheles australasiae (Fabricius)

open access: yesStudies on the thelytokous parthenogenesis in the scorpion, Liocheles australasiae (Fabricius)
本論文は,サソリ類(蛛形綱,サソリ目)において初めて,雌性産生単為生殖の過程および機構を,組織学的観察,核学的観察,および核DNA量の測定にもとづいて解明したものである。 ヤエヤマサソリはアジア・太平洋地域に広く分布し,沖縄県八重山諸島を分布の北限とする胎生のサソリである。西表島のヤエヤマサソリ個体群が雌性産生単為生殖によって維持されていることは,野外調査および実験室内での個別継代飼育によって明らかにされていたが,母虫卵巣内において卵の成熟から発生の単為的開始に至る過程および機構については,不明であった。 著者は,卒業研究以来約6年間にわたって,多数のヤエヤマサソリを実験室内で個別継代飼育し,厳密な単為的条件下で,卵の成熟から発生の開始に至る間の核DNA量の変遷を共焦点レーザー顕微鏡下で測定し ...
