Similar but distinct ovipositor steering mechanisms in members of the parasitic wasp families Gasteruptiidae and Aulacidae are described. In both of these there are abrupt stops near the apex of each of the upper and lower ovipositor valves. These stops, which are closely apposed when the ovipositor is at rest, prevent the lower valves from being extended posteriorly relative to the upper valve. Attempts to extend the lower valves posteriorly force the ovipositor to bend dorsally. This ability…

The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae)
TLDR
It is reported that in the ichneumonid group of koinobiont spider-ectoparasitoids (“polysphinctines”), several putatively ancestral taxa, parasitic on ground-dwelling RTA-spiders (a group characterised by retrolateral tibial apophysis on male palpal tibiae), lay their eggs in a specific way.
Morphology and ultrastructure of sense organs on the ovipositor of Trybliographa rapae, a parasitoid of the cabbage root fly.
TLDR
The ovipositor of the parasitoid wasp Trybliographa rapae was examined by scanning and transmission electron microscopy and it is suggested that the remaining dendrites are gustatory, and as such probably respond to factors present in host haemolymph.
Sense organs on the ovipositor of Macrocentrus cingulum Brischke (Hymenoptera: Braconidae): their probable role in stinging, oviposition and host selection process
TLDR
The morphology and ultrastructure of sense organs on the ovipositor and sheath of Macrocentrus cingulum Brischke (Hymenoptera: Braconidae) are described using scanning and transmission electron microscopy, and the olistheter-like interlocking mechanism, as well as the morphology of the ventrals and dorsal valve tips and the ventral valve seal may be important in stinging, oviposition and in the host selection process.
The ovipositor apparatus of basal Hymenoptera (Insecta): phylogenetic implications and functional morphology
TLDR
The skeleto‐musculature of the ovipositor apparatus and the external sculpture of the 1st and 2nd valvulae was studied in representatives from all ‘symphytan’ families and the configuration of the musculature did not display much variation among the taxa examined.
The ovipositor actuation mechanism of a parasitic wasp and its functional implications
TLDR
The findings improve the comprehension of hymenopteran probing mechanisms, the function of the associated muscles, and the forces and damage‐limiting mechanism that are involved in drilling a slender terebra into a substrate.
Morphology and function of the ovipositor mechanism in Ceraphronoidea (Hymenoptera, Apocrita)
TLDR
Overall, the ceraphronoid ovipositor system is highly variable and can be described by discrete, distinguishable character states, however, these differences do not reflect the present classification of the superfamily and might represent parallelisms driven by host biology.
Structure and Sense Organs of Ovipositors of an Endoparasitoid Aprostocetus causalis and an Ectoparasitoid Quadrastichus mendeli in Leptocybe spp.
TLDR
The morphology, types, distribution, length, and width of these sensilla and microtrichia were described, and their possible functions are discussed in conjunction with the stinging, oviposition, and the host selection process.
Structure and function of the stylets of hematophagous Triatominae (Hemiptera: Reduviidae), with special reference to Dipetalogaster maxima.
TLDR
Compared the morphological structure of the stylets (mandibles and maxillae) of four triatomine species and analyzed the feeding process of Dipetalogaster maxima, finding that the mechanical interaction of the two maxillary abutments enables the distal opening of the food channel but might also support the movements of the maxillary bundle attributable to different bending moment distributions.
Manganese and zinc in the ovipositors and mandibles of hymenopterous insects
X-ray microanalysis of the ovipositor and mandibles of various hymenopterous insects has revealed the presence in many species of up to 10% wt/wt of either zinc or manganese in the cuticle. These
Functional anatomy of the ovipositor clip in the parasitoid leptopilina heterotoma (Thompson) (Hymenoptera : Eucoilidae), a structure to grip escaping host larvae
TLDR
The functioning of the ovipositor clip is discussed and it is suggested that this wasp can hold a host larvae in a fixed position until the larva is paralyzed.

A mechanism for movement of eggs along insect ovipositors
TLDR
The mechanism by which eggs are moved along the length of the ovipositor of insects is described, which involves a series of posteriorly orientated scales that catch the surface of the egg as it emerges from the oviduct and move it along the ovipsitor as the valves oscillate back and forth.
Biosystematics and Morphology of Symphyta. Ii. Biology of Gall-Making Nematine Sawflies in the California Region
Female sawflies in 3 genera of tenthredinid Hymenopterain the subfamily Nematinae (Phyllocolpa, Pontania, and Euura) incite a gall (procecidium) on Salicaceae during oviposition by injecting modified
Evolutionary Morphology of the External Insect Genitalia. 2. Hymenoptera
TLDR
The Hymenoptera have the least sexually dimorphic combined with the least specialized genitalia among the Pterygota and the ovipositor has lost its egg-laying function in the latter and becomes the sting.
Evolutionary Morphology of External Insect Genitalia. 1. Origin and Relationships to Other Appendages
TLDR
The notum formed through fusion of the dorsal (euventral) rami of gonapophyses IX is a landmark in both sexes of nearly all insects.
Host finding by Rhyssa persuasoria (L.), and ichneumonid parasite of siricid woodwasps.
TLDR
Females are able to detect and parasitize dead hosts in logs, demonstrating that sound is not a necessary stimulus for drilling, and is not essential for host detection.
Ovipositor structure and relationships within the Hymenoptera, with special reference to the Ichneumonoidea
TLDR
The morphology, function and phylogenetic significance of the hymenopterous ovipositor, as revealed by transverse sections, is explored and functional interpretations are given for several characters, with particular reference to substrate penetration, passage of the egg along the ovipOSitor and stinging.
Biosystematics and Morphology of Symphyta. I. Stem-Galling Euura of the California Region, and a New Female Genitalic Nomenclature
TLDR
The morphology of the female ovipositor reflects the physical structure and ecology of the host plant and the site galled, as well as the phylogeny of the insect, and can be used to delineate both willow and sawfly taxa.
Ovipositor mechanics of the braconine wasp genus Zaglyptogastra and the ichneumonid genus Pristomerus
TLDR
The multiply-arched, apical quarter to half of the ovipositors of Zaglyptogastra species are capable of flexing ventrally through up to 180°, an action which juxtaposes swollen lower valve sections with weak concave narrowings of the upper valve.
