Convergence in the ovipositor system of platygastroid wasps (Hymenoptera) [PDF]

open access: yesJournal of Hymenoptera Research, 2017
It is widely accepted that there are two ovipositor system types in Platygastroidea. The Scelio-type ovipositor system features telescoping conjunctiva between metasomal tergites 6 and 7 and operates via internal changes in hydrostatic pressure alone ...

On the Morphology of the Ovipositor of Certain Anthomyian Genera* [PDF]

open access: greenAnnals of the Entomological Society of America, 1921
This difficult family of flies has caused not only the systematist but also the economic entomologist no little misapprehension due to the unsatisfactory conception of existing taxonomic characters. The generic definitions are also ambiguous and are at present undergoing a thorough revision.

Morphology and function of the ovipositor mechanism in Ceraphronoidea (Hymenoptera, Apocrita) [PDF]

open access: yesJournal of Hymenoptera Research, 2013
The ovipositor of apocritan Hymenoptera is an invaluable source of phylogenetically relevant characters, and our understanding of its functional morphology stands to enlighten us about parasitoid life history strategies. Although Ceraphronoidea is one of

Morphology of exophytic ovipositors in dragonflies (Odonata: Gomphidae, Corduliidae, Libellulidae), with particular reference to ovipositor muscles and sensilla [PDF]

open access: hybridInternational Journal of Odonatology, 2011
A comparative study of female external genitalia was carried out in representatives of three dragonfly families that lay eggs exophytically, with special emphasis placed on skeletal musculature and sensilla. Female external genitalia are characteristically represented by the vulvar lamina and rudiments on the 9th sternum.

Extraordinary drilling capabilities of the tiny parasitoid Eupelmus messene Walker (Hymenoptera, Eupelmidae) [PDF]

open access: yesJournal of Hymenoptera Research, 2023
In the course of evolution, animals and particularly insects, have developed efficient and complex mechanisms for survival. Biomimetics aims to find applications for these features of organisms (or organs) in industry, agriculture, and medicine.
