Evidence for Carboniferous origin of the order Mantodea (Insecta: Dictyoptera) gained from forewing morphology
The homology statement implies that the total-group Mantodea arose as soon as the Late Carboniferous, i.e. about 175 million years earlier than previously estimated, suggesting a survivorship of several main Pterygota lineages at the end-Permian extinction event higher than previously expected.
Venation pattern and revision of Orthoptera sensu nov. and sister groups. Phylogeny of Palaeozoic and Mesozoic Orthoptera sensu nov.
In this analysis the Orthoptera were not clearly affected by the Permo-Triassic biodiversity “crisis” and the relationships between Caelifera and Ensifera sensu nov., and those between the major clades of modern EnsiferA sensuNov.
Cnemidolestodea (Insecta): An ancient order reinstated
- O. Béthoux
- 1 January 2005
This work has found the first evidence of the extinction of a high‐rank insect taxon at this period, and the hypothesis that insects experienced a faunal turnover from the Late Carboniferous to the Early Permian needs to be tested.
An integrative phylogenomic approach illuminates the evolutionary history of cockroaches and termites (Blattodea)

The first nuclear phylogenomic study of termites and cockroaches with a thorough approach to divergence time analysis, identification of endosymbionts, and reconstruction of ancestral morphological traits and behaviour shows that most subgroups of Blattodea evolved in the Cretaceous.
At last, a Pennsylvanian stem-stonefly (Plecoptera) discovered

Continuing efforts on the systematics of Pennsylvanian winged insects indicate a fauna more diverse than previously appreciated, which suggests that insects already had a long, yet undocumented, history by this time.
Earliest Evidence of Insect Endophytic Oviposition
The antiquity of the insect endophytic oviposition behavior suggests that it could have been important during the emergence and diversification of the insects group.
New Data on Homocladus grandis, A Permian Stem-Mantodean (Polyneoptera: Dictyoptera)
The range of morphological variation exhibited by the new material, in addition to wing morphology variability documented in extant mantises and roaches, suggest that H. grandis is a strephocladid species that exhibits a combination of character states unique to dictyopteran insects.
WING VENATION PATTERN OF PLECOPTERA ( INSECTA : NEOPTERA )
- O. Béthoux
Some consider the order Plecoptera as the sister-group of all neopterous insects. Hence the interpretation of Plecoptera wing venation has critical implications for character polarization among basal…
A first higher-level time-calibrated phylogeny of antlions (Neuroptera: Myrmeleontidae).
- B. Michel, Anne-Laure Clamens, O. Béthoux, G. Kergoat, F. Condamine
- Biology, MedicineMolecular phylogenetics and evolution
- 1 February 2017
Dating analyses indicate that the antlion family likely originated in the Cretaceous, between 135 and 138 million years ago (depending on the set of fossil calibrations), and that all higher-level lineages appeared during the EarlyCretaceous.
An Innovative Control Strategy of a Single Converter for Hybrid Fuel Cell/Supercapacitor Power Source
- T. Azib, O. Béthoux, G. Remy, C. Marchand, E. Berthelot
- Engineering, Computer ScienceIEEE Transactions on Industrial Electronics
- 1 March 2010
An innovative control strategy for hybrid power sources dedicated to automotive applications, based on a cascaded control loop with a decoupling strategy in the frequency domain, is detailed.
