Le quart de la biodiversité forestière est « saproxylique » (associée au bois mort et aux micro-habitats portés par les [vieux] arbres). Les insectes coléoptères, riches de 2663 espèces attachées à 74 familles en France, et qui dominent le cortège saproxylique avec les champignons, constituent ainsi un groupe indicateur fréquemment utilisé dans l...
In the nineties, John Cairns emphasized the importance of developing a field of «landscape ecotoxicology». Indeed, landscape features influence both abiotic and biotic processes, such as pollutant transfers in the different compartments of the environment, or population dynamics of beneficial organisms. Realistic ecotoxicological scenarios therefor...
An illustrated key to french species of the genus Corticaria is provided.
An identification key in French and English is presented for the 18 Salpingidae species found in France. For each species are proposed short diagnosis, life history, and updated distribution map in France, based on collection specimens and selected litterature data.
Lyctoxylon dentatum (Pascoe, 1866) (Coleoptera Bostrichidae Lyctinae) a été observé pour la première fois en France à Versailles (Yvelines), dans un lot de tuteurs horticoles en bambou importés d’Asie. L’espèce cohabitait avec Dinoderus minutus (F., 1775) (Bostrichidae Bostrichinae) et Tarsostenus univittatus (Rossi, 1792) (Cleridae).
L’objectif de cet ouvrage de terrain est de permettre une identification simple et accessible de près de 500 espèces de coléoptères du Bassin parisien. Les auteurs se sont affranchis des clefs dichotomiques habituellement utilisées pour l'identification, ce qui rend la démarche accessible aux naturalistes comme au grand public curieux de nature. Le...

3,4-Dihydro-9-hydroxy-3-m ethylisocoum arin [R (-) - mellein] was identified as the major component of themale wing gland pheromone of the bumble-bee wax moth, Aphomia sociella L. (Pyralidae, Galleriinae). The presence of Aspergillus ochraceus Wilhelm, a mellein producing microorganism, was detected in the intestinesof last-instar larvae andinbumbl...
Paysandisia archon was accidentally introduced into Europe where it damages endemic and ornamental palms, also threatening the date palm from North Africa. Little was known about sex pheromones in the Castniidae day-flying moth before a recent paper that concluded on the absence of female sex pheromone in P. archon. A putative identification of a s...
The five synthetic pheromone components of the West Indian sugarcane borer (WISB), Metamasius hemipterus (L.) (Coleoptera, Curculionidae) were tested in the field. The combination of sugarcane (SC) and the major pheromone compound, 4-methyl-5-nonanol (1) was attractive. However, the addition of 2-methyl-4-heptanol (2) or 2-methyl-4-octanol (3) was...
The synthesis of difluorinated analogue of an insect sex pheromone has been accomplished through intramolecular radical cyclization and lipase-catalyzed reaction. Optically active α,α-difluoroeldanolide and its antipode have been synthesized. Dose-response curves constructed from electroantennogram responses of female moths showed the difluoroanalo...

L’étude de l’entomofaune des saproxyliques de la forêt de la Tour du Lay à permis de mettre en évidence une part importante des coléoptères présent sur la forêt mais ce relevé faunistique ne pourrait constituer à lui seul un inventaire exhaustif. Un travail important reste à réaliser pour aller plus loin et poser les bases d’un suivi local et dépar...
In 2005, the Department of Seine-et-Marne (25 km away from Paris, France) initiated a large project dedicated to monitor the biodiversity (fauna, flora and habitats) on its territory. For the study of the fauna, five vertebrate groups and five insect groups have been retained, among which the saproxylic beetles.
This group is monitored by means of...
Males and females of many moth species exhibit important differences in sexual behaviours. Much research in this field has focused on the male-specific behaviour, electrophysiology and molecular biology of sex pheromone reception. Female-specific behaviours have been less well studied although, like male-specific behaviours, they could provide oppo...
Dès 1988, le Conseil de l'Europe encourageait les gouvernements européens à utiliser prioritairement les organismes associés au bois mort, dits saproxyliques, pour évaluer l'état de conservation des forêts (Recommandations R(88)10 et 11 sur la protection des organismes saproxyliques et de leurs biotopes). Toutefois, presque 20 ans après, peu d'outi...
Attraction of the large pine weevil, Hylobius abietis (L.) (Coleoptera: Curculionidae) to pine logs was enhanced by the presence of weevils already on the logs. We investigated the volatiles emitted by insects feeding on host trees to determine the mechanism of the attraction. Chemical analyses of the collected volatiles showed large amounts of mon...
The violet click beetle Limoniscus violaceus (P.W.J. Müller, 1821) (Elateridae) is a threatened species inhabiting hollow trees. The habitat of the beetle was examined in the managed forest of Grésigne (southwestern France). Emergence traps (nylon mesh covering the whole opening of the tree cavity) were set up on 111 oak trees to assess the occurre...

Techniques for continuous rearing of Rhynchophorus palmarum, using either a semi-synthetic diet or fresh pieces of sugarcane, are described. Both methods successfully provided small numbers of adults within 4 months. Use of sugarcane was cheaper than the semi-synthetic diet. The method was also useful for rearing R. vulneratus.
Male American palm weevils (APWs),Rhynchophorus palmarum (L.) produced two sex-specific compounds, which were disclosed by volatile collections on Supelpak-2 and gas chromatography. One was a minor compound, not always detected. The major male-produced volatile was identified as (2E)-6-methyl-2-hepten-4-ol through coupled gas chromatography-mass sp...
Four components, (Z)-9-tetradecenal (8.6%), (Z,E)-9,12-tetradecadienal (4.8%), (Z)-11-hexadecenal (49.5%), and (Z)-13-octadecenal (37.1%), were identified in extracts of female pheromone glands of the European sunflower moth,Homoeosoma nebulellum (Lepidoptera: Pyralidae) using GC and GC-MS analyses. EAG and single-cell recordings of male antennal r...
Field trapping of the American palm weevil (APW),Rhynchophorus palmarum, showed that the combination of caged male APWs and palm stem was much more attractive to APWs of both sexes than palm stem alone. Caged female APWs did not enhance the attractiveness of the palm. Caged APWs without palm stem were not attractive. Virgin laboratory-bred males we...
The synthesis of four stereoisomers of the female-produced sex pheromone [(2R,6R,10R)-, (2S,6R,10R)-, (2S,6S,10S)-, and (2R,6S,10S)-1a] of the rice moth (Corcyra cephalonica) was achieved by starting from (R)-2a, (R)- or (S)-3a, and (R)- or (S)-4 and using alkylation of alkyl phenyl sulfones as the coupling reaction. Behavioral bioassay of each iso...
Behavioral observations of the rice moth (Corcyra cephalonica, Pyralidae, Galleriinae) in the laboratory have shown that a male wing-gland pheromone induces attraction of female moths. This pheromone was identified as a blend of (E,E) and (Z,E)-farnesal. Wing-gland extracts or synthetic compounds were shown to be attractive to females by inducing w...
Laboratory investigations of mating behavior in the rice moth,Corcyra cephalonica Stainton (Lepidoptera: Pyralidae; Galleriinae) showed that male moths are attracted at short range to live, virgin female moths and to female abdominal-tip extract. Volatiles collected from virgin female moths contained one component eliciting an electroantennographic...
