Mantodea plays a special role in the food chain as a group charismatic generalist predators. They regulate invertebrate populations while themselves being prey for many larger animals such as reptiles and birds. The present study focuses on Fench Guiana where about 78 species are known within eight families. This diversity represents a challenge for specimen identification.The MANGF project aims at developing a DNA metabarcoding approach to facilitate and enhance the monitoring of mantises as indicators in ecological studies. As a first step towards that goal, we assembled a library of DNA barcodes using the standard genetic marker for animals, i.e. a portion of the COI mitochondrial gene. In the present contribution, we release a library including 425 records representing 68 species in eight different families. Species were identified by expert taxonomists and each record is linked to a voucher specimen to enable future morphological examination. We also highlight and briefly discuss cases of low interspecific divergences, as well as cases of high intraspecific divergences that might represent cases of overlooked or cryptic diversity.

Understanding resin flows within 3D interlock fabrics involves addressing a dual-scale flow problem. Indeed, the fluid can flow through inter-yarn channels, characterized by a unit cell mesoscale morphology, but also within yarns considered as homogeneous equivalent porous media. The former is assumed to follow the Stokes’ law while the latter be related to the Darcy’s law, directly linked to the microscopic intra-yarn fiber volume fraction (FVF) field. In this work, a coupled Stokes–Darcy steady-state flow within a 3D woven textile, modeled at mesoscale, is solved through a finite element monolithic approach with a mixed velocity-pressure formulation, stabilized by the Variational MultiScale Method (VMS) and implemented in the Z-set software. The fabric permeability tensor is then computed without any assumptions on its nature and analyzed both through its diagonal components, its eigenvectors and eigenvalues. The main contribution of this study lies in examining the influence of variations of the inter-yarn porous medium morphology, through textile compaction and geometrical reduction to prevent edge flows, and the intra-yarn permeability (from complete field to unique value) on the overall fabric permeability.

This article presents an innovative approach to modeling particle bed growth through suspension dead-end filtration, a process of paramount importance in various industrial and environmental contexts. More precisely, it focuses on the numerical formulation of a continuous approach based on a Stokes-Darcy coupling. In a Level-Set/FEM frame, this model effectively captures the dynamic evolution of particle beds (cake), taking into account the interaction between suspended particles and porous media. Model validation is also a key focus of this paper. Numerical tests are carried out under various conditions, and their results are compared with analytical solutions and experimental data drawn from the literature. This permits corroboration of the predictive capabilities of the model, confirming the robustness and accuracy of the proposed approach. Firstly, Stokes-Darcy coupled flows are investigated in simplified cases such as rectangular geometries and coaxial cylinders. These scenarios serve as benchmarks to assess the model performance under simple and varied conditions. Additionally, the more challenging case of a three-dimensional anisotropic flow between two ellipsoids is addressed, where the evolution of the cake takes place in three dimensions. Through rigorous analysis and comparison with analytical solutions, the model is proved efficient in capturing the inherent complexities of such scenarios. Finally, richer two-dimensional Stokes-Darcy flows are considered, in the presence of both impermeable and permeable obstacles, representing a crucial step towards modeling real industrial processes. This last study highlights not only the formation of particle-free zones but also the practical relevance of this work.

Vates marmorata n. sp. and Vates patrinata n. sp. (Mantidae, Vatinae) are described from French Guiana. The new species are close to V. biplagiata and V. festae, all exhibiting strong tubercles along pronotal margins but differing in male genital structures. Description, images, and measurements of anatomical parts are presented, along with distributional, natural history, and DNA barcoding data. A key to species of Vates known in French Guiana is formulated. This study highlights the value of DNA barcoding in disclosing hidden diversity in Mantodea, especially when coupled with traditional taxonomic tools.

Transient two-phase flows within fibrous media are considered at local scale. Upscaling these flows constitute a key procedure towards a tractable description in an industrial context. However, the task remains challenging as a time-dependent behaviour is observed within a geometrically complex structure with interplay of various physical phenomena (capillary effects, viscous dissipation, etc.). The usual upscaling strategies encountered in both soil sciences and composite materials communities are reviewed, compared, and finally adapted to reach a method that is relevant to describe fibrous media imbibition. Using finite element flow simulations on statistical representative volume elements, the proposed approach first considers several definitions for saturation in order to characterise the flow dynamics as well as the characteristic length associated with the transient behaviour. Next, two methods are proposed to assess a resulting capillary pressure, demonstrating the importance to properly define the capillary pressure acting on the interface. The first one considers the mean pressure jump at the interface, while the second one uses a machine-learning technique, namely Gaussian process regression, to retrieve the mean curvature of the interface. Those methods are found to be both consistent and in agreement with the results from the literature. Finally, a novel approach that stochastically describes the position of the flow front through a presence distribution is detailed. The spread of the front can be compared to the saturation length, and its value has been found to be small enough to be neglected at upper scale, justifying the use of sharp interface models for similar porous media and flow settings.

Hierodula transcaucasica Brunner von Wattenwyl, 1878, is here reported for the first time in France. A well settled and probably widespread population of this species is discussed. Some considerations of the potential impacts on the local ecosystems and its future spreading in Europe as an invasive species are given.

Microwave heating of pure alumina is studied experimentally and numerically, in a 2.45 GHz single-mode cavity, for different density levels. Even considering a constant incident power, the results show a complex evolution of the alumina temperature: first a two-step increase, then a maximum, and finally a cooling stage. In addition, a density dependence of the heating efficiency is observed: a more efficient heating occurs for lower densities. Using the effective medium approximation (EMA) to derive the physical data as functions of density, the numerical simulations are in contradiction with the experiments, proving that the EMA approach is not able to correctly predict the imaginary part of the permittivity. Furthermore, the simulations do not accurately describe the first moments of the heating, nor the long-term evolution of the temperature (cooling). We then explain the origin of this discrepancy: the need to adjust the movable stub on the one hand, and to account for heat exchange between the cavity and its surroundings on the other.

Despite recent developments in the systematics of Acanthopinae Burmeister, 1838, the generic identity of two species, Acanthops parva Beier, 1942 and A. soukana Roy, 2002 remained ambiguous. The examination of the types and of previously unstudied specimens necessitated the creation of two new genera. Royacanthops n. gen. is introduced to accommodate Acanthops soukana Roy, 2002, and a new species from Brazil. Parvacanthops Schwarz & Moulin, n. gen. is proposed for Acanthops parva Beier, 1942. The resulting new combinations are Royacanthops soukana (Roy, 2002) n. comb. and Parvacanthops parva (Beier, 1942) n. comb. The male of R. soukana n. comb. is described for the first time. Three specimens from Brazil are described as Royacanthops confusa Schwarz & Moulin, n. gen., n. sp. The new genera are easily separated from other genera of Acanthopinae by morphological and genital characters. The geographic distribution of the two genera is briefly discussed.

The little mantid Callimantis antillarum (Saussure, 1859) is recorded for the first time from Anguilla. It is the first report in Eastern Caribbean Islands while the species is known from Virgin Islands and Greater Antilles.

Recently detected in Martinique, Chloronia antilliensis Flint, 1970, is known from Dominica and Saint Lucia islands. During an entomological survey for a diachronic study of some insects’ families in the south of the Parc National de Guadeloupe, a female of this species was observed. It is confirmed that this endemic species of Eastern Caribbean Islands is related to the wetlands of mountain areas.

Background: The management of bleeding originating from the guttural pouch (GP) has a high success rate, but the resolution of the macroscopic inflammatory lesions in the case of mycosis (GPM) is highly variable; the resolution of neurological disorders is inconstant and challenging. Objectives: Our aim was to test the feasibility and safety of topical oxygen therapy (TOT) in horses after induction of GPM and in cases with naturally occurring disease. Study design: This study was an in vivo experimental and retrospective two-phase study. Methods: During phase 1, the pilot study, both GPs were inoculated with Aspergillus fumigatus. One GP was randomly assigned to receive one to four TOT 30 min sessions with 100% medical oxygen at 9 L/min. Follow-up endoscopic images were assessed for scoring macroscopic inflammatory lesions of the pharynx and both GPs. In phase 2, the clinical study, TOT was administered for 45 to 60 min at 15 L/min in six horses presenting with GPM. Results: In phase 1, TOT administration was easy to perform in the standing horse with no adverse effects. After more than two administrations, macroscopic inflammatory lesions decreased more quickly in size in the treated GP. In phase 2, horses were treated with TOT only (n = 1) or combined with a transarterial coil embolization (TACE) procedure (n = 5). After TOT and discharge from the hospital, nasal discharge resolved in three horses, and improvement was noted in the fourth one. Between days 2 and 10 after admission, upper respiratory tract endoscopy (URTE) indicated size reduction and alteration in the appearance of all the macroscopic inflammatory lesions. The partial or total recovery of neurological disorders (2/4 laryngeal hemiparesis, 3/5 dysphagia, 1/2 dorsal displacement of the soft palate (DDSP), and 1/1 Horner's syndrome) was recorded. Main limitations: In phase 1, the small number of horses did not allow for statistically significant conclusions; in phase 2, clinical signs at admission varied between horses, which made comparison difficult. Conclusions: In adult horses, TOT alone or in combination with TACE is feasible and safe with a propensity to reverse the course and the progression of inflammatory lesions without additional local or systemic treatment.

Summary Whereas Mantises of Trinidad and Tobago have been comprehensively studied, species occurring on more northern islands of Lesser Antilles are little known. The present work aims at updating the current knowledge on Mantises from Eastern Caribbean Islands by compiling data from both published and grey literature, museum specimens as well as specimens we and others collected during surveys conducted over the last decades. Thesprotiella insularis (Bonfils, 1967) is revealed to be widely distributed on islands harboring moist and wet forests from Martinique to Guadeloupe. Liturgusa dominica Svenson, 2014 occurs in humid and subhumid forests of Dominica and Marie-Galante. Gonatista reticulata (Thunberg, 1815) and Thesprotia caribea Rehn & Hebard, 1938 appear restricted to the northernmost islands of the Northeast Lesser Antilles. Musonia surinama Saussure, 1869 is present in the grassland of St Martin and of Southern islands (Barbados, St. Vincent, and Grenada). Lobocneme lobipes (Redtenbacher, 1892) is only present in St. Vincent and Grenada. Epaphrodita undulata (Saussure, 1870) is re-established as synonym of Epaphrodita musarum (Palisot de Beauvois, 1805); this species was described from St. Lucia, but has not been recorded for over 150 years. Finally, a specimen of Bantiella trinitatis Giglio-Tos, 1915 was collected on Martinique in 1975, but this species was not collected again. Despite intensive searching, four non-endemic species once recorded on the archipelago have not been recorded again and might correspond to temporary settlements or to erroneous data. Acontista multicolor Saussure, 1870 does not appear to currently occur on Guadeloupe. Distribution, ecology and phenology of these species are discussed.

Recent years have seen the development and democratization of continuous fibre composite materials for the manufacture of primary aeronautical structures. Composite materials exhibit excellent specific properties compared to aluminium alloys historically used for these applications. The need in cadence improvement leads the aeronautic industry to consider new processes for primary aeronautical structures manufacturing. Therefore, new dry reinforcements are developed, such as the HiTape® reinforcement designed by Hexcel Reinforcements. HiTape® plies are designed for automated laying in order to build dry stacks that can be formed and infused/injected by a liquid resin afterwards to greatly increase the production rates. To understand and predict results from the forming stage, numerical models are considered as a useful tool. In this work, we propose a new computational approach to model the forming stage of dry HiTape® stacks. The HiTape® ply is a slender structure, exhibiting a transversely isotropic behaviour in large deformations as well as a non-linear bending behaviour. Another particularity is that the bending stiffness of the ply is not directly related its membrane stiffness. When stacks are considered, inter-ply phenomena (opening and sliding) appear and greatly influence the bending stiffness of the structure. To model every of these specificities, diverse techniques are used: solid-shell elements are considered to answer the ply slenderness, embedded elements approach helps to model the membrane/bending behaviours decoupling, frictional cohesive zone model stands for inter-ply phenomena and the particular behaviour of the ply is described using a non-linear physical-invariant based hyperelastic constitutive. The finite element (FE) software Abaqus will be used in this work.

In the context of developing competitive liquid composites molding processes for primary aircraft structures, modeling the forming stage of automatically-placed initially flat stacks of dry reinforcements is of great interest. In the case of HiTape®, a dry unidirectional carbon fiber reinforcement designed to achieve performances comparable to state-of-the-art pre-impregnated materials, the presence of a thermoplastic veil on each side of the material for both processing and mechanical purposes should also be considered when modeling forming in hot conditions. As a dry unidirectional reinforcement, HiTape® is expected to exhibit a transversely isotropic behavior. Computation cost and strong characterization challenges led us to model its behavior at the forming process temperature (above the thermoplastic veil melting temperature) through a homogeneous equivalent continuous medium exhibiting four ‘classical’ deformation modes and a specific structural mode, namely out-of-plane bending. The response of both single plies and stacks of HiTape® to this latter structural mode was characterized at the forming process temperature using a modified Peirce flexometer . Results on single plies showed a non-linear softening moment-curvature behavior and a corresponding flexural stiffness much lower than what can be inferred from continuum mechanics. Moreover, testing stacks revealed that the veil acts as a thin load transfer layer between the plies undergoing relative in-plane displacement, i.e. inter-ply sliding. This inter-ply response was then characterized separately at the forming process temperature thanks to a specific method relying on a pull-through test. Experiments performed at pressures and speeds representative of the forming stage revealed that a hydrodynamic lubricated friction regime predominates, i.e. a linearly increasing relationship between the friction coefficient and the modified Hersey number. From an industrial point of view, high forming pressures and low speeds are therefore recommended to promote inter-ply slip to limit the occurrence of defects such as wrinkles.
