AUTOMICTIC PARTHENOGENESIS AND ITS GENETIC CONSEQUENCE IN BACILLUS-ATTICUS-ATTICUS (INSECTA PHASMATODEA)

, 1993
The meiotic divisions in the eggs of the diploid thelytokous stick insect Bacillus atticus atticus (2n=34 or 33) were examined in Feulgen squashes. The reduction division is normal and results in two interphase nuclei.

Strategies of Laying Workers in Populations of the Honeybee, Apis mellifera {Hymenoptera:

, 2008
In colonies of Apis mellifera Linnaeus 1758, VP develop their o.varies and start laying eggs after they become queenless. Usually dd develop from these Qlaid eggs (arrhenotokous parthenogenesis). In Apis mellifera capensis Escholtz 1822 laying 89 produce

Meiotic recombination dramatically decreased in thelytokous queens of the little fire ant and their sexually produced workers

, 2011
The little fire ant, Wasmannia auropunctata, displays a peculiar breeding system polymorphism. Classical haplo-diploid sexual reproduction between reproductive individuals occurs in some populations, whereas, in others, queens and males reproduce ...

Parthenogenesis under influence of microbes in Thysanoptera

, 2008
Der Reproduktionsmechanismus der meisten Thysanopteren beruht auf Haplodiploidie (EVANS et al. 2004). Die Mehrzahl der Arten vermehrt sich durch Arrhenotokie. Bei einigen Arten sind Männchen jedoch sehr selten, sie vermehren sich durch Thelytokie.

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

Studies 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 ...
