Odour conditioning of ovipositor probing in a parasitic wasp

Ethology Ecology & Evolution, 1995
We investigated the occurrence of odour learning in the ovipositor probing activity of Leptopilina boulardi, a parasitoid of Drosophila larvae. A device was set up to observe the probing behaviour in response to an odour. Systematic and persistent probing in response to the odour (banana) was observed after associative conditioning, i.e., after the ...

Structure of ovipositors and cladoendesis of Saltatoria, or Orchesopia

Entomological Review, 2016
The oldest circumscriptional names of the taxon under consideration are Orchesopia Rafinesque, 1815 and Saltatoria Latreille, 1817. The recent Saltatoria are divided into two subordinate taxa whose circumscriptional names are Dolichocera Bey-Bienko, 1964 and Caelifera Ander, 1936 [= Metorthoptera Crampton, 1927 = Brachycera Bey-Bienko, 1964 (non ...

Superextension and supercontraction in locust ovipositor muscles

Journal of Insect Physiology, 1983
Abstract 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.

Flexible ovipositor sheaths in parasitoid Hymenoptera (Insecta)

Arthropod Structure & Development, 2003
The 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.

Structure of the Ovipositor of Hylotrupes bajulus (Coleoptera: Cerambycidae)

Annals of the Entomological Society of America, 1986
The female of Hylotrupes bajulus (L.) has an elongated ovipositor comprising modified abdominal segments 8 and 9, intersegmental membrane 8/9, and a pair of distal gonostyli. When not in use, the ovipositor is retracted within abdominal segment 7. An internal apodeme attached to the base of the 8th sternite allows for extension and retraction of the ...

The Functional Morphology and Interpretation of the Insect Ovipositor

The Canadian Entomologist, 1961
Elsewhere (Scudder, 1957a), I have outlined briefly a revised interpretation of some basal structures in the insect ovipositor. It was shown that in insects other than the Machilidae, the female genitalia has a common plan, this plan differing from that usually taken as the basic type. Whilst Snodgrass (1933) based his interpretations of all the higher

The Ovipositor System of Isostasius (Platygastroidae: Platygastreidae)

The ovipositor of Isostasius species is unique to the Platygastridae family and is characterized by a system of coiled valvulae. This morphological structure acts as a hypodermic needle comprising hollow tubes that facilitate egg-laying. The coiling mechanism assists in oviposition in parasitoid wasps, encouraging egg deposition in isolated larvae with

Reinterpretation of some Basal Structures in the Insect Ovipositor

Nature, 1957
SNODGRASS1 based his interpretation of the female genitalia of the higher insect orders on the condition in Machilidae. In this family the ovipositor on the eighth and ninth segments is derived from the limb bases. The limb bases of the eighth segment (first genital) may be termed the first gonocoxae (1Gx) with the styli, the first gonostyli (1Gs) and ...
