Scanning electron microscopy analysis of the antennal sensilla in therare saproxylic beetle Elater ferrugineus (Coleoptera: Elateridae)

This work provides the first morphological analysis (both at gross and fine level) of the antennal structures in the genusElater (Coleoptera, Elateridae). The typology, number and distribution patterns of the antennal sensilla in the rare saproxylicElater ferrugineus (both male and female) were studied using scanning electron microscopy (SEM). The serrate antennae ofE. ferrugineus consisted of a scape, a pedicel, and nine flattened flagellomeres. Overall, 10 types of sensilla were identifiedaccording to their morphological features: one type of sensilla chaetica (Ch), one type of Böhm sensilla (Bo), three types ofsensilla trichodea (Tr.1–3), two types of sensilla basiconica (Ba.1–2), one type of sensilla styloconica (St), one type ofgrooved peg sensilla (Gp) and one type of sensilla campaniformia (Ca). A marked sexual dimorphism was found at bothgross and fine scale. The male antenna was bigger (8.6 mm) than the female one (7.0 mm) and carried one type of sensillatrichodea (Tr.2) absent in female antennae possibly responsible for reception of the female-emitted sex pheromone. Thefemale antenna carried a higher number of sensilla (~ 9800) than the male one did (~7,000), with more abundant sensillachaetica (Ch) and basiconica (Ba.1 and Ba.2)

The PLATO Mission

International audiencePLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2 R_(Earth)) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations from the ground, planets will be characterised for their radius, mass, and age with high accuracy (5 %, 10 %, 10 % for an Earth-Sun combination respectively). PLATO will provide us with a large-scale catalogue of well-characterised small planets up to intermediate orbital periods, relevant for a meaningful comparison to planet formation theories and to better understand planet evolution. It will make possible comparative exoplanetology to place our Solar System planets in a broader context. In parallel, PLATO will study (host) stars using asteroseismology, allowing us to determine the stellar properties with high accuracy, substantially enhancing our knowledge of stellar structure and evolution. The payload instrument consists of 26 cameras with 12cm aperture each. For at least four years, the mission will perform high-precision photometric measurements. Here we review the science objectives, present PLATO's target samples and fields, provide an overview of expected core science performance as well as a description of the instrument and the mission profile at the beginning of the serial production of the flight cameras. PLATO is scheduled for a launch date end 2026. This overview therefore provides a summary of the mission to the community in preparation of the upcoming operational phases
