Automictic parthenogenesis in the parasitoid Venturia canescens (Hymenoptera: Ichneumonidae) revisited.
Both arrhenotokous and thelytokous reproduction are known to occur in the parasitoid wasp Venturia canescens. The cytological mechanism of thelytoky was previously reported to involve the formation of a restitution metaphase after the reduction division, but the exact nature of the subsequent divisions, whether reductional or equational, remained unclear. We reinvestigated the cytological mecha...
متن کاملThelytokous parthenogenesis in eusocial Hymenoptera.
Female parthenogenesis, or thelytoky, is particularly common in solitary Hymenoptera. Only more recently has it become clear that many eusocial species also regularly reproduce thelytokously, and here we provide a comprehensive overview. Especially in ants, thelytoky underlies a variety of idiosyncratic life histories with unique evolutionary and ecological consequences. In all eusocial species...
متن کاملStudy of the subfamily Ophioninae (Hymenoptera: Ichneumonidae) in southern Iran
تحقیق حاضر جهت تعیین گونههای زیرخانواده Ophioninae (Hymenoptera: Ichneumonidae) در بعضی قسمتهای جنوبی ایران (استانهای فارس و هرمزگان) انجام شد. نمونهها طی سالهای 1391-1392 با استفاده از تلههای مالیز، نوری و تور حشرهگیری در زیست‌گاههای مختلف جمع‌آوری شدند. دوازده گونه متعلق به سه جنس (Enicospilus Stephens, 1835؛ Ophion Fabricius و Eremotylus Forster) شناسایی شدند که از بین آنها پنج گونه...

متن کاملStatus of Ichneumonidae (Hymenoptera: Ichneumonoidea) in Cuba.
Current understanding of Cuban ichneumonids (Hymenoptera: Ichneumonoidea) is analysed. A new Subfamily (Tersilochinae) including 13 genera and two species are first reports for Cuba. In contrast with Braconidae, the sister group, the ichneumonids are poorly known because of the lack of local taxonomists and bacause nets, rather than interception, light and yellow pan traps have been used. Using...
