Ovipositor-inspired steerable needle: design and preliminary experimental evaluation
Bioinspiration & Biomimetics, 2017Flexible steerable needles have the potential to allow surgeons to reach deep targets inside the human body with higher accuracy than rigid needles do. Furthermore, by maneuvering around critical anatomical structures, steerable needles could limit the risk of tissue damage. However, the design of a thin needle (e.g.

Flexible ovipositor sheaths in parasitoid Hymenoptera (Insecta)
Arthropod Structure & Development, 2003The structure of the ovipositor sheaths is examined in a number of parasitic wasps as well as a few non-parasitic taxa. Parasitic wasps in the families Aulacidae, Braconidae, Ichneumonidae, Megalyridae, and Stephanidae with a very elongate, external ovipositor have the lateral wall of the sheath finely transversely subdivided by narrow furrows.

The gustatory sensilla on the endophytic ovipositor of Odonata
Arthropod Structure & Development, 2013The present paper aims at describing the fine structure of coeloconic sensilla located on the cutting valves of the endophytic ovipositor of two Odonata species, the anisopteran Aeshna cyanea (Aeshnidae) and the zygopteran Ischnura elegans (Coenagrionidae), by carrying out parallel investigations under SEM and TEM.

Superextension and supercontraction in locust ovipositor muscles
Journal of Insect Physiology, 1983Abstract A ten times elongation of certain abdominal intersegmental muscles occurs in female locusts during digging prior to oviposition. During and after oviposition the muscles contract, shortening by up to 90% or more, restoring the resting positions of the abdominal segments.

Testing hypotheses of adaptive variation in cricket ovipositor lengths
Oecologia, 1993We experimentally tested a series of hypotheses proposed by Masaki (1979, 1986) for the evolution of ovipositor length in crickets. Female crickets use the ovipositor to bury eggs in the soil, where it was hypothesized to protect their eggs from desiccation, cold and other disturbance.
